stereovslam

Feature-based visual simultaneous localization and mapping (vSLAM) with stereo camera

Since R2024a

Description

Use the stereovslam object to perform visual simultaneous localization and mapping (vSLAM) with stereo camera data. To learn more about visual SLAM, see Implement Visual SLAM in MATLAB.

The stereovslam object extracts Oriented FAST and Rotated BRIEF (ORB) features from incrementally read images, and then tracks those features to estimate camera poses, identify key frames, and reconstruct a 3-D environment. The vSLAM algorithm also searches for loop closures using the bag-of-features algorithm, and then optimizes the camera poses using pose graph optimization.

Note

To use the stereovslam object, you must have a Navigation Toolbox™ license.

Creation

Syntax

vslam = stereovslam(intrinsics,baseline)

vslam = stereovslam(reprojectionMatrix,imageSize)

vslam = stereovslam(___,Name=Value)

Description

vslam = stereovslam(intrinsics,baseline) creates a stereo visual SLAM object, vslam, using the rectified stereo camera intrinsic parameters intrinsics, and the baseline distance between the rectified left and right cameras.

The object represents 3-D map points and camera poses in world coordinates, and assumes the camera pose of the first key frame is an identity rigidtform3d transform.

Note

The stereovslam object runs on multiple threads internally, which can delay the processing of an image frame added by using the addFrame function. Additionally, the object running on multiple threads means the current frame the object is processing can be different than the recently added frame.

vslam = stereovslam(reprojectionMatrix,imageSize) creates a stereo visual SLAM object vslam using the stereo camera reprojection matrix, reprojectionMatrix, and the image size, imageSize.

vslam = stereovslam(___,Name=Value) sets properties using one or more name-value arguments in addition to any combination of input arguments from previous syntaxes. For example, MaxNumPoints=850 sets the maximum number of ORB feature points to extract from each image to 850.

Input Arguments

intrinsics — Rectified stereo camera intrinsic parameters

cameraIntrinsics object

Rectified stereo camera intrinsic parameters, specified as a cameraIntrinsics object.

baseline — Distance between rectified left and right cameras

nonnegative scalar

Distance between the rectified left and right cameras, specified as a nonnegative scalar. Stereo vSLAM algorithms typically track the primary (or left) camera, in which case the baseline is greater than zero. A negative baseline value indicates a negative disparity range, and the vSLAM algorithm tracks the secondary (or right) camera instead.

reprojectionMatrix — Reprojection matrix

4-by-4 matrix

Reprojection matrix, specified as a 4-by-4 matrix of the form:

$${\left[\begin{array}{cccc}1& 0& 0& -cx\\ 0& 1& 0& -cy\\ 0& 0& 0& f\\ 0& 0& 1/b& 0\end{array}\right]}_{,}$$

where f and (cx, cy) are the focal length and principal point of rectified primary camera, respectively. b is the baseline of the virtual rectified stereo camera.

You can obtain the reprojection matrix by using the rectifyStereoImages function.

imageSize — Image size produced by camera

two-element vector

Image size produced by the camera, in pixels, specified as a two-element vector of the form [nrows ncols]. The elements nrows and ncols represent represents the number of rows and columns, respectively.

Properties

DepthScaleFactor — Depth scale factor

scalar

This property is read-only.

Depth scale factor, specified as a scalar in real-world units (e.g., meters). The depth scale factor depends on the depth sensor, and it is typically expressed in the same unit as the depth measurements provided by the sensor (e.g., millimeters, centimeters, or meters). It is the conversion factor that relates the depth values to real-world distances. In other words, it provides the necessary information to transform the depth measurements into metric scale.

For the world 3-D coordinates (X,Y,Z), where Z represents depth at any pixel coordinate (u,v), Z would be computed as Z = P/depthScaleFactor, where P represents the intensity value of the depth image at pixel (u,v). You must set this property at object creation.

ScaleFactor — Scale factor for image decomposition

1.2 (default) | scalar greater than 1

This property is read-only.

Scale factor for image decomposition, stored as a scalar greater than 1. The scale factor is also referred to as the pyramid decimation ratio. Increasing the value of ScaleFactor reduces the number of pyramid levels, and computation time, but at the cost of tracking performance. Decreasing this value, increases the number of pyramid levels, which can improve tracking performance, at the cost of computation speed. The scale value at each level of decomposition is ScaleFactor^{(level – 1)}, where level is any value in the range [0, NumLevels-1]. Given an input image of size M-by-N, the image size at each level of composition is M_level-by-N_level, where:

$$\begin{array}{l}{M}_{level}=\frac{M}{ScaleFacto{r}^{(level-1)}}\\ N_{level}=\frac{N}{ScaleFacto{r}^{(level-1)}}\end{array}$$

You must set this property at object creation.

Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint64 | uint32

NumLevels — Number of decomposition levels

8 (default) | scalar greater than or equal to 1

This property is read-only.

Number of decomposition levels, specified as a scalar greater than or equal to 1. Increase this value to extract keypoints from the image at more levels of decomposition. Along with the ScaleFactor value, NumLevels controls the number of pyramid levels on which the object evaluates feature points.

The image size at each decomposition level limits the number of levels at which you can extract keypoints. The image size at a level of decomposition must be at least 63-by-63 for keypoint detection. The maximum level of decomposition is:

$$leve{l}_{\max }\text{ = floor}\left(\frac{\log \left(\min \left(M,N\right)\right)-\log \left(63\right)}{\log \left(\text{ScaleFactor}\right)}\right)+1$$

If either the default value or the specified value of NumLevels is greater than level_max, the object reduces NumLevels to level_max and returns a warning. You must set this property at object creation.

Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint64 | uint32

MaxNumPoints — Maximum number of ORB feature points uniformly extracted from each image

1000 | positive integer

This property is read-only.

Maximum number of ORB feature points uniformly extracted from each image, specified as a positive integer. Values are typically in the range of [800, 2000], depending on the resolution of the image. When the number of extracted features is less than the value of MaxNumPoints, then the object uses all feature points. You must set this property at object creation.

DisparityRange — Disparity range

[0 48] (default) | two-element vector of integers

This property is read-only.

Disparity range, specified as a two-element vector of integers of the form [min max]. The elements specify the minimum and maximum disparity, respectively. The range must be within the width of the image, and the difference between the minimum and the maximum must be divisible by 16.

UniquenessThreshold — Minimum value of uniqueness

15 (default) | nonnegative integer

Minimum value of uniqueness, specified as a nonnegative integer.

The function marks the estimated disparity value K for a pixel as unreliable if:

v < V×(1 + 0.01×UniquenessThreshold),

where V is the sum of the absolute difference (SAD) corresponding to the disparity value K, and v is the smallest SAD value over the whole disparity range, excluding K, K–1, and K+1.

Increasing the value of UniquenessThreshold results in the function marking disparity values for more pixels as unreliable. To turn off the uniqueness threshold, set this value to 0.

TrackFeatureRange — Range for the number of feature points to identify key frame

[30 100] | 2-element vector

This property is read-only.

Key frame feature point range, stored as a two-element vector of the form [lowerLimit upperLimit]. This property specifies the minimum and maximum numbers of tracked feature points a frame must contain for the object to identify it as a key frame. The TrackFeatureRange and the SkipMaxFrames properties enable you to control the frequency at which frames in the tracking process become key frames. You must set this property at object creation.

The success of tracking depends on the number of tracked points in the current frame, with one of these results:

• Tracking is lost — The number of tracked feature points in the current frame is less than the lowerLimit set by the TrackFeatureRange argument. This indicates that the image does not contain enough features, or that the camera is moving too fast. If the object does not accept enough frames as key frames, to improve tracking, you can increase the upperLimit value of the TrackFeatureRange property and decrease the SkipMaxFrames property to add key frames more frequently.

• Tracking is successful — The object identifies the current frame as a key frame. The number of tracked feature points in the current frame is in the range set by TrackFeatureRange.

• Tracking adds key frames too frequently — The number of tracked feature points in the current frame is greater than the upperLimit set by the TrackFeatureRange property. This indicates that the camera is moving very slowly, which produces an unnecessary number of key frames. To reduce the frequency at which the object adds key frames and improve tracking, you can increase the value of the SkipMaxFrames argument.

For more details, see the addFrame object function.

SkipMaxFrames — Maximum number of skipped frames

20 | positive integer

This property is read-only.

Maximum number of skipped frames, stored as a positive integer. When the number of tracked features is consistently greater than the upperLimit set by the TrackFeatureRange property, use the SkipMaxFrames property to control the frequency of adding new key frames. The object identifies the current frame as a key frame when the number of skipped frames since the previous key frame added equals the value of SkipMaxFrames.

LoopClosureThreshold — Minimum number of matched feature points between loop closure key frames

60 | positive integer

This property is read-only.

Minimum number of matched feature points between loop closure key frames, stored as a positive integer.

CustomBagOfFeatures — Custom bag of features for loop detection

[] (default) | bagOfFeaturesDBoW object

Custom bag of features for loop detection, specified as a bagOfFeaturesDBoW object. The bagOfFeaturesDBoW enables you to create a custom bag of words (BoW) from feature descriptors, alongside options to utilize a built-in vocabulary or load a custom one from a specified file.

Verbose — Progress information display

[] (default) | 1 | 2 | 3

Progress information display, specified as [], 1, 2, or 3. Paths to the location of log files, when they are created, is displayed on the command line.

Verbose value	Display description	Display location
[] or false	Display is turned off
1 or true	Stages of vSLAM execution	Command window
2	Stages of vSLAM execution, with details on how the frame is processed, such as the artifacts used to initialize the map.	Log file in a temporary folder
3	Stages of vSLAM, artifacts used to initialize the map, poses and map points before and after bundle adjustment, and loop closure optimization data.	Log file in a temporary folder

Examples

Stereo Visual SLAM Using UTIAS Data Set

Perform stereo visual simultaneous localization and mapping (vSLAM) using the data from the UTIAS Long-Term Localization and Mapping Dataset provided by University of Toronto Institute for Aerospace Studies. You can download the data to a directory using a web browser, or by running this code:

ftpObj = ftp("asrl3.utias.utoronto.ca");
tempFolder = fullfile(tempdir);
dataFolder = [tempFolder,"2020-vtr-dataset/UTIAS-In-The-Dark/"];
zipFileName = [dataFolder,"run_000005.zip"];
folderExists = exist(dataFolder,"dir");

Create a folder in a temporary directory to save the dowloaded file and extract its contents.

if ~folderExists  
    mkdir(dataFolder) 
    disp("Downloading run_000005.zip (818 MB). This download can take a few minutes.") 
    mget(ftpObj,"/2020-vtr-dataset/UTIAS-In-The-Dark/run_000005.zip",tempFolder);

    disp("Extracting run_000005.zip (818 MB) ...") 
    unzip(zipFileName,dataFolder); 
end

Downloading run_000005.zip (818 MB). This download can take a few minutes.

Extracting run_000005.zip (818 MB) ...

Create two imageDatastore objects to store the stereo images.

imgFolderLeft = [dataFolder,"/images/left/"];
imgFolderRight = [dataFolder,"/images/right/"];
imdsLeft = imageDatastore(imgFolderLeft);
imdsRight = imageDatastore(imgFolderRight);

Specify the intrinsic parameters and the baseline of the stereo camera, and use them to create a stereo visual SLAM object. The focal length, principal point, and image size is in pixels, and the baseline is in meters.

focalLength = [387.777, 387.777];  
principalPoint = [257.446, 197.718];  
imageSize = [384,512];            
intrinsics = cameraIntrinsics(focalLength,principalPoint,imageSize);
baseline = 0.239965; 

vslam = stereovslam(intrinsics,baseline,MaxNumPoints=600, ...
    TrackFeatureRange=[30 120],SkipMaxFrames=5);

Process each pair of stereo images and visualize the camera poses and 3-D map points.

for i = 1:numel(imdsLeft.Files)
    leftImage = readimage(imdsLeft,i);
    rightImage = readimage(imdsRight,i);
    addFrame(vslam,leftImage,rightImage);

    if hasNewKeyFrame(vslam)
        % Query 3-D map points and camera poses
        xyzPoints = mapPoints(vslam);
        [camPoses,viewIds] = poses(vslam);

        % Display 3-D map points and camera trajectory
        plot(vslam);
    end

    % Get current status of system
    status = checkStatus(vslam);
    
    % Stop adding frames when tracking is lost
    if status == uint8(0)
        break
    end

Tips

• The stereovslam object:

  • Does not account for lens distortion. You can undistort the images by using the undistortImage function before adding images.

  • Assumes images have been rectified. You can rectify undistorted stereo images by using the rectifyStereoImages function before adding images.

  • Runs on multiple threads internally, which can delay the processing of an image frame added by using the addFrame function. Additionally, the object running on multiple threads means the current frame the object is processing can be different than the most recently added frame.

• The camera poses are the poses of the primary camera, which corresponds to the input image I1 added by the addFrame object function.

• The object represents 3-D map points and camera poses in world coordinates. The object assumes the camera pose of the first key frame is an identity rigidtform3d transform.
