Abstract
A cascading expansion method of working space and working visual angle of stereo vision system is disclosed. One stereo vision system in the multi stereo vision systems is fixed as the global vision system, and the other stereo vision systems can move the position and adjust the visual angle according to the needs during the working process, so as to effectively expand the working space and working visual angle of the stereo vision system and improve the flexibility of the stereo vision system. For the target to be measured that cannot be seen under the global stereo vision, the indirect positioning of the target to be measured under the global coordinate system can be achieved through other stereo vision systems, so as to overcome the limitation of the limited visual angle of a single stereo vision system and the limited workspace.
