Abstract

The embodiment of the invention discloses a welding seam surface topography three-dimensional imaging device. The imaging device comprises a light source assembly, an interference assembly, an image acquisition assembly and an imaging assembly; the light source assembly is used for emitting light beams required for measuring the surface of a weld joint; the interference assembly is used for receiving the light beams emitted by the light source assembly, reflecting a first path of light beams in the light beams and transmitting a second path of light beams in the light beams; the second path oflight beams is transmitted to the surface of the weld joint; the reflected light beams of the second path of light beams are received; interference light beams formed by the first path of light beamsand the reflected light beams are emitted; the image acquisition assembly is used for acquiring the interference light beams emitted by the interference assembly to obtain an interference image; andthe imaging assembly is used for determining depth information of the surface of the weld joint based on interference fringes formed by the interference light beams in the interference image acquiredby the image acquisition assembly, and performing three-dimensional imaging on the surface of the weld joint based on the depth information.

Description

technical field [0001] The invention relates to imaging technology, in particular to a three-dimensional imaging device for weld surface topography. Background technique [0002] Welding is widely used in the fields of aerospace, automobiles and ships. As one of the effective means of welding quality assessment, weld quality inspection is of great significance for ensuring welding quality, improving welding process and increasing the life of parts. The efficiency and quality of weld formation inspection is directly related to the production efficiency and automation of the production line, and it also plays a positive role in saving labor and improving the working environment of workers. [0003] At present, the surface quality inspection of welds is still mainly based on manual visual observation (or supplemented by grinding). The inspection accuracy depends on the experience and level of the operator, and the inspection efficiency is very low and the quality fluctuates gre...
