A laser three-dimensional measuring system and its measuring method

Abstract

The invention provides a laser three-dimensional measurement system and a measurement method thereof which are used for performing three-dimensional measurement on to-be-measured objects in any shapes. The laser three-dimensional measurement system includes an X movement shaft, a plurality of Y movement shafts vertical to the X movement shaft, a movement control system fixed on the X movement shaft, an image acquisition device and an automatic rotation moving slide stage which are fixed on the X movement shaft, a laser three-dimensional measuring device fixed on the automatic rotation moving slide stage, and clamps fixed on the Y movement shafts, wherein the clamps are used for fixing measured objects. According to the laser three-dimensional measurement system of the invention, image acquisition of the measured objects is realized through the image acquisition device; image processing is performed on acquired images through the image acquisition device, so that the surface profiles of the measured objects can be obtained; accurate translation and rotational positioning are performed on the measured objects through the movement control system; and therefore, laser three-dimensional measurement of real-time profile tracking can be realized. With the laser three-dimensional measurement system adopted, the automation of detection can be realized, and detection efficiency, detection accuracy and detection accuracy can be improved.

Description

technical field [0001] The invention relates to laser measurement technology, in particular to a general real-time contour tracking laser three-dimensional measurement system and a measurement method thereof. Background technique [0002] In the detection process, objects with regular shapes can be automatically detected by laser three-dimensional measurement method, but it is difficult to realize automatic detection for objects with arbitrary shapes. At present, the detection and measurement methods used by most manufacturers are manual inspection, and there are often many uncertainties in the results of manual inspection, which have not been quantified. Inspectors repeat high-intensity operations every day, and it is impossible for them to accurately judge each product. On the one hand, the above-mentioned methods cause customer complaints and product returns artificially during the inspection process, which will bring a lot of money and reputation loss to the company; on...
