Based on Opencv binocular camera camera program

This article shares the specific code of Opencv binocular camera program for your reference. The specific content is as follows

The binocular camera I use is an usb cable connected to the computer. The operating environment is vc2015, opencv3.0. Save the pictures from the left and right cameras separately.
