Allows to grab images from a PointGrey camera using FlyCapture SDK.
To use this class install first FlyCapture SDK https://www.ptgrey.com/flycapture-sdk. Installation instructions are provide here https://visp.inria.fr/3rd_flycapture.
Once installed configure ViSP using cmake to detect FlyCapture SDK and build ViSP to include FlyCapture SDK support.
This class was tested under Ubuntu and Windows with the following cameras:
The following example shows how to use this class to capture images from the first camera that is found.
If more than one camera is detected, you can use setCamera(const unsigned int &) to select the camera of interest.
It is also possible to capture images from multiple cameras. The following example shows how to capture simultaneously images from multiple cameras.

exposure_auto | : If true set auto exposure, if false set manual exposure applying exposure_value parameter. |
exposure_value | : This is the average intensity of the image. It will use other available (non-manually adjustable) controls to adjust the image. Specifically, when shutter and gain are both in auto mode, manually adjusting the exposure is actually adjusting the auto-exposure, which tries to make the average intensity of the image 1/4 of the auto-exposure value e.g. exposure is 400, the camera will try to adjust shutter and gain so that the average image intensity is 100. When the auto-exposure mode is enabled for exposure, the camera tries to manipulate shutter and gain such that 5% of the image is saturated (pixel value of 255). |
