Abstract

The invention provides a laser demarcation device calibration system which comprises a base, a support and eight sampling light tubes. The support is fixed on the base, the sampling light tubes are fixed on the support, each sampling light tube comprises a collimator, a digital camera, a lens positioning sleeve and a light tube sleeve, each collimator is fixed on the support through the corresponding light tube sleeve, each lens positioning sleeve is fixed on the corresponding collimator, each digital camera is connected with the corresponding lens positioning sleeve sequentially through an interface converting member and a lens sleeve, and a USB (universal serial bus) interface is arranged at the front end of each digital camera. The laser demarcation device calibration system is combined with technology of light tube small angle measuring, machine vision measuring, data fusion and the like to perform accuracy detection and calibration on a laser demarcation device, and detection results can be quantified, stored and subjected to database creating management. The laser demarcation device calibration system is convenient to assemble and disassemble, simple to calibrate and small in occupied area, damage of laser to human eyes can be greatly reduced, workload of personnel can be reduced, influences of subjective factors of human beings can be avoided, and efficiency and accuracy of detection and calibration are improved.

Description

technical field [0001] The present invention relates to a calibration system for a laser line thrower, in particular to a digital detection and calibration system for a laser line thrower based on machine vision measurement technology. Background technique [0002] The laser line thrower is a new type of laser miniaturized surveying and mapping measuring instrument. Due to its low cost, simple operation, reliable accuracy and non-contact measurement method, the laser line thrower is widely used in machining, furniture manufacturing, architectural decoration, etc. The field has been popularized and the market prospect is broad. Most of them use 635nm laser diodes, which can project visible red horizontal straight lines and lead vertical lines on the surface of the object to be shot, such as the wall, to play the role of marking the reference line, so the laser line projector is also called the laser line marker. In recent years, a line projector using a green laser with a wa...
