Flexible-layout vision-assisted laser galvanometer scanning system and on-site calibration method thereof

The invention provides a flexible-layout vision-assisted laser galvanometer scanning system and an on-site calibration method thereof. The system comprises a laser galvanometer scanning system, a visual positioning device and a calibration device. The calibration device is a piece of calibration flat plate, wherein one surface of the calibration flat plate is an interval-known black circular array standard template pattern, and the other surface is a smooth plane suitable for laser spot imaging. The calibration method enables the calibration result of the laser galvanometer scanning system to be also suitable to a field binocular system coordinate system through coordinate transformation relation of coordinate systems of the calibration results of the binocular stereo vision system coordinate system and an original galvanometer scanning system, thereby realizing on-site calibration of the laser galvanometer scanning system; the calibration method is simple to operate, short in consumed time, high in calibrati
