Problems solved by technology
In terms of precision measurement, the measurement accuracy is far from enough and has not yet reached the ideal value
Especially in terms of binocular measurement (that is, stereo measurement), the matching accuracy is still not up to date. Because the same spatial point has different spatial positions in the two cameras, there is a certain parallax. How to calculate the parallax depends on the distance between the two left and right images. Matching, if the matching accuracy cannot be achieved, the subsequent 3D reconstruction will be more difficult, that is to say, stereo matching and 3D reconstruction are still a major problem in visual measurement

Embodiment
[0040] The invention is positioned as an important supporting module in the visual measurement system, which is used for unified control of laser emitters and industrial cameras, and is the technical basis of laser scanning imaging. The visual measurement system consists of figure 1 shown.
[0041] Such as figure 2 Shown: The integrated control system uses STM32F429 produced by ST Company as the main control chip, and three components including the control board, laser module board and secondary power supply board are designed, and Ethernet and RS485 are extended on the control board. The interface can perform data interaction with the host computer and other network devices, and realize unified control of laser transmitters and industrial cameras. The system connects the image host computer and other peripherals in a bridging manner, so that the image host computer can operate all peripherals through UDP commands, thereby effectively improving the working quality and effic...
