Abstract

The invention discloses a positioning method of a distance measurement laser point of a remote distance measurement system based on coaxial dual lasers. According to the invention, the mode that green laser and red distance measurement laser are coaxially transmitted is utilized to realize the fact that a user can view a scene picture at a client operation end, and the functions such as measurement on actual distance, storage and filing, video caption superposition and the like can be realized through any two point in a picture identified and point-selected by the green laser, thereby solvingthe problem of visual positioning of the laser point in the remote distance measurement system under the conditions of long measurement range and strong ambient light.

Description

technical field

[0001] The invention relates to a distance-measuring laser point positioning method of a remote distance-measuring system based on dual-light coaxial implementation. Background technique

[0002] The remote distance measurement system adopts the combination of laser distance measurement and network video, so that the user can watch the live picture at the client operation end, and measure the actual distance between any two points in the selected picture, which is convenient for the user to remotely measure the remote distance. Measurement of the length of any object at the location of the ranging terminal and the distance between two points. Practice has proved that the system has a good application prospect in engineering survey, port, highway and subway construction survey, crop growth supervision and analysis, geological safety and other aspects. However, in practical applications, the following problems often occur when the ranging laser point is visual...
