Coplanar adjustment system and method for laser profiler array

Abstract

The invention discloses a laser profiler array coplanar adjustment system and method. A multi-laser profilometer is used for shooting markers, a coordinate system is established, positional relationships between each laser profilometer and the markers are calculated so as to calculate positional relationships between different laser profilometers, the laser profiler array coplanar adjustment method is anintuitive adjustment methodwhich converts coplanar adjustment into position adjustment for laser profilometers, by adjusting the position of the laser profilometersthrough an adjusting structure, the position information of the laser profilometers is fed back in real time duringadjustment, and finally the multi-laser profilometer reaches a coplanar state. According to the laser profiler array coplanar adjustment system and method, data feedback of laser profilometers are used for coplanar adjustment, multiple laser profilometers can be subjected to the coplanar adjustment simultaneously, laser ray coplanar adjustment information can be converted into intuitive laser profilometer position adjustment information,a real-time feedback characteristic is obtained,and through the laser profilometer array coplanar adjustment method, the problems of great difficulty, low efficiency, and low precision in adjusting the coplanarity of the multi-laser profilometer can be solved.

Description

technical field [0001] The invention relates to the technical field of installation adjustment, in particular to a coplanar adjustment system and method of a laser profiler array. Background technique [0002] In recent years, with the vigorous development of laser measurement technology and industry, a single laser profiler has been unable to meet people's expectations for large-scale measurement data due to its limited measurement range. The combination of multiple laser profilers to complete measurement tasks has gradually become the current research. hotspot. [0003] During the installation process of the laser profiler, the coplanar adjustment of the laser profiler is a very critical link. The accuracy of the adjustment result directly affects the accuracy of data acquisition and calculation in the subsequent system. Therefore, it is necessary to do a good job of the coplanarity of the laser profiler Adjustment is the first prerequisite for the smooth completion of th...

Problems solved by technology

[0005] The first is that the operator judges whether the laser profiler is coplanar by observing whether the laser lines are on a straight line with human eyes. However, the laser line itself has a certain width, and the overlapping parts of the two laser lines are brighter and thicker than a single laser line. It is difficult to judge whether the laser line is aligned with the naked eye; if the operator looks directly at the laser line for a long time, it will cause certain damage to the eyes; coplanar adjustment needs to adjust three dimensions, and adjusting one dimension will affect the other two dimensions. Personnel often adjust repeatedly in the "coming to a coplanar state", and the final adjustment result is also an "almost coplanar state". From the above, it can be seen that this method is not only difficult to adjust, but also low in efficiency and accuracy. Difficult to meet expectations

[0006] The second is to make a coplanar mold in advance, and fix the position of the laser profiler through the mold. This method is limited by the mechanical structure, and different molds need to be made in different positions, and the mold requires high processing accuracy, making high processing accuracy The cost of the mold is very high, and the cost of the mold is higher than the price of the project itself. Most projects cannot afford the high mold cost, so this method is abandoned
