technical field

The invention relates to an on-site light environment automatic measurement and positioning device, which belongs to the field of photoelectric detection.

Background technique

According to the distance measured by the photoelectric range finder and the azimuth angle measured by the azimuth angle measuring device, the position of the ambient light measuring device can be determined by the triangular geometric relationship. The measurement and control terminal receives the signal from the position positioning device and the signal from the ambient light measurement device and sends out a control driving signal to realize fast, accurate and automatic measurement of light environment data, and is easy to use and operate.

Further, the photoelectric range finder includes a laser range finder and a scanning device, and the scanning device is connected with the azimuth measuring device.
