Abstract

The invention discloses a weld joint structure three-dimensional point cloud measurement method, and the method comprises the steps: controlling a line structured light sensor to project a laser line to cover a target region, and enabling the target region to be the region where a to-be-detected weld joint is located; acquiring measurement data of the target area based on a distance measurement sensor, an attitude measurement sensor and the linear structured light sensor; and generating a three-dimensional point cloud of the to-be-detected weld joint structure based on the measurement data and outputting the three-dimensional point cloud. According to the scheme of the invention, the line structured light sensor, the distance measurement sensor and the attitude measurement sensor are integrated to automatically and comprehensively measure the weld joint structure and obtain the three-dimensional point cloud of the to-be-detected weld joint architecture. The efficiency and precision of weld joint measurement are improved, comprehensive coverage measurement of the weld joint is achieved, and the three-dimensional point cloud of the weld joint structure is obtained.

Description

technical field [0001] The invention relates to the technical field of weld seam measurement, in particular to a three-dimensional point cloud measurement method for weld seam structures. Background technique [0002] With the development of the industrial level, the types and numbers of welding products are increasing, and the welding quality of welding products is also getting more and more attention. Welding quality mainly depends on the overall size of weld structure, weld structure and mechanical properties, etc. Among them, the overall size of weld structure is an important indicator to measure welding quality. Today, weld seam measurement is an important step in the production line. [0003] In the prior art, the weld seam is usually measured manually, and the operator uses a welding calibration ruler to measure the weld seam. The problem of the prior art is that the manual measurement of the weld structure using a welding calibration ruler has low measurement effic...
