Syntax

poseTable = mountingPose(multiSensorObj)
[mountingAngles,mountingLocation] = mountingPose(multiSensorObj,name)

Description

poseTable = mountingPose(multiSensorObj) returns a table containing the mounting poses of all sensors in multiSensorObj.

example

[mountingAngles,mountingLocation] = mountingPose(multiSensorObj,name) returns the mounting orientations and locations for the sensor or sensors in multiSensorObj specified by name.

Get the transformation from the front camera to the front lidar sensor.

tform = transformation(multiSensorObj,"front_camera","front_gt");

Get the camera intrinsic parameters of the front camera.

camIntrinsicsFront = intrinsics(multiSensorObj,"front_camera");

Get the mounting angles and mounting location of the front camera.

[mountingAngles,mountingLocation] = mountingPose(multiSensorObj,"front_camera");

Input Arguments

collapse all

Multi-sensor parameters object to get mounting poses from, specified as a multiSensorParameters object.

Name of the sensor, specified as a string scalar, character vector, M-element string array, or an M cell array of character vectors.

Output Arguments

collapse all

Mounting poses of all the sensors, returned as a table. The table contains the name, mounting angles, and mounting locations of all sensors in multiSensorObj.

Mounting orientation angles of the sensor, returned as a three-element vector or an M-by-3 matrix in which each row is of the form [yaw pitch roll], with respect to the reference frame coordinate system. The yaw, pitch, and roll are positive rotations about the z-axis, intermediate y-axis, and intermediate x-axis of the reference frame, respectively. Units are in degrees.

Mounting location of the sensor, returned as a three-element vector or an M-by-3 matrix in which each row is of the form [x y z], expressed in the reference frame, in meters.
