Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a multi-camera synchronous triggering system with high precision and low power consumption. Background technique [0002] Binocular stereo vision measurement imitates the way humans observe the world, observes the same object from two or more points at the same time to obtain images from different perspectives, matches the same pixels between images, and then according to the parallax (offset between pixels) and triangulation principle to obtain the three-dimensional space information of the measured object. Camera synchronization means that each camera is exposed at the same time. For stationary objects, multi-camera exposure out of sync will not bring obvious errors to the measurement, but for moving objects, especially high-speed moving objects, multi-camera exposure out of sync will cause measurement errors. Bring huge error, even can't match the same pixel. [00...
