Is it possible for OSDK to obtain stereo vision images in multiple directions at the same time?

Keywords: OSDK stereo vision，advance sensing

The OSDK sample itself does not support simultaneous acquisition of stereo video stream in multiple directions. If it is needed, you can try multi-threaded processing.

Because the OSDK USB port on the 430 is USB 2.0, the theoretical maximum transfer rate of USB2.0 is 480Mbps, that is, 60MB/s, and the actual maximum bandwidth is smaller.

The stereo vision image is divided into 6 directions, two images in each direction, the stereo vision image displayed with 20 fps VGA (640x480) resolution, the theoretical bandwidth of a single channel (2 images) is 12MB/S

The actual measurement can take 2-3 directions images (4-6 images) at the same time, and the bandwidth is 24-36MB/S. Taking into account some scheduling overhead and USB also enumerates virtual serial ports, there is some bandwidth occupation, so it is recommended not to exceed 3 channels(6 images) of images.
