gigecam

Create gigecam object to acquire images from GigE Vision cameras

Syntax

g = gigecam

g = gigecam('IPAddress')

g = gigecam(devicenumber)

g = gigecam('serialnumber')

Description

g = gigecam creates the gigecam object g and connects to the single GigE Vision^® camera on your system. If you have multiple cameras and you use the gigecam function with no input argument, then it creates the object and connects it to the first camera it finds listed in the output of the gigecamlist function.

When the gigecam object is created, it connects to the camera and establishes exclusive access. You can then preview the data and acquire images using the snapshot function.

g = gigecam('IPAddress') creates a gigecam object g where IPAddress is a character vector value that identifies a particular camera by its IP address and connects it to the camera with that address.

g = gigecam(devicenumber) creates a gigecam object g, where devicenumber is a numeric scalar value that identifies a particular camera by its index number, and connects it to that camera.

g = gigecam('serialnumber') creates a gigecam object g where serialnumber is a character vector value that identifies a particular camera by its serial number.

Examples

Create a gigecam Object Using No Arguments

Use the gigecam function with no input arguments to connect to the single GigE Vision camera on your system. If you have multiple cameras and you use the gigecam function with no input argument, it creates the object and connects it to the first camera it finds listed in the output of the gigecamlist function.

Use the gigecamlist function to ensure that MATLAB^® is discovering your camera.

It creates the object and connects it to the Photonofocus AG camera.

Create a gigecam Object Using IP Address or Serial Number

Use the gigecam function with the IP address or serial number of the camera as the input argument to create the object and connect it to the camera with that address or number.

Use the gigecamlist function to ensure that MATLAB is discovering your cameras.

Create an object, g, using the IP address of the camera. You can also create the object in this same way using the serial number. You use the same syntax, but use a serial number instead of the IP address, also as a character vector.

g = gigecam('169.254.242.122')

g =

It creates the object and connects it to the Matrix Vision camera with that IP address.

Create a gigecam Object Using Device Number as an Index

Use the gigecam function with an index as the input argument to create the object corresponding to that index and connect it to that camera. The index corresponds to the order of cameras in the table returned by gigecamlist when you have multiple cameras connected.

Use the gigecamlist function to ensure that MATLAB is discovering your cameras.

It creates the object and connects it to the Matrix Vision camera with that index number, in this case, the second one displayed by gigecamlist. If you only have one camera, you do not need to use the index.

Input Arguments

IPAddress — IP address of your camera

character vector

IP address of your camera, specified as a character vector. This argument creates a gigecam object g where IPAddress is a character vector value that identifies a particular camera by its IP address. When you use the gigecam function with the IP address of the camera as the input argument, it creates the object and connects it to the camera with that address. You can see the IP address for your camera in the list returned by the gigecamlist function.

Example: g = gigecam('169.254.192.165')

Data Types: char | string

devicenumber — Device number of your camera

numeric scalar

Device number of your camera, specified as a numeric scalar. This number identifies a particular camera by its index order. It creates the object corresponding to that index and connects it to that camera. The index corresponds to the order of cameras in the table returned by gigecamlist when you have multiple cameras connected.

Example: g = gigecam(2)

Data Types: double

serialnumber — Serial number of your camera

character vector

Serial number of your camera, specified as a character vector. This argument creates a gigecam object g where serialnumber is a character vector value that identifies a particular camera by its serial number. When you use the gigecam function with the serial number of the camera as the input argument, it creates the object and connects it to the camera with that number. You can see the serial number for your camera in the list returned by the gigecamlist function.

Example: g = gigecam('022600017445')

Data Types: char | string

Tips

• When the gigecam object is created, it connects to the camera and establishes exclusive access. You can then preview the data and acquire images using the snapshot function.

• You cannot create more than one object connected to the same device, and trying to do that generates an error.
