The invention provides a synchronous acquisition device and a method for two-dimensional and three-dimensional images. The acquisition device comprises a scanning unit used for acquiring the daytime frames and the night frames of a to-be-detected workpiece, and a calculation unit used for processing the daytime frames and the night frames and generating a two-dimensional texture diagram and a three-dimensional point cloud diagram of the to-be-detected workpiece. The scanning unit is in communication connection with the calculation unit. The calculation unit is further used for controlling the working state of the scanning unit. The two-dimensional texture diagram is obtained through the image splicing process according to displacement information between daytime frames. The three-dimensional point cloud diagram is obtained through the image splicing process according to the displacement information between night frames. The coordinate correspondence relation exists between the two-dimensional texture diagram and the three-dimensional point cloud diagram. According to the synchronous acquisition device and the method for two-dimensional and three-dimensional images, the two-dimensional texture diagram and the three-dimensional point cloud diagram of the to-be-detected workpiece can be acquired synchronously. Meanwhile, the three-dimensional point cloud diagram and the two-dimensional texture diagram accurately correspond to each other in XY coordinate relationship, so that collecting and measuring results are more accurate.
Description
Technical field [0001] The invention belongs to the field of image acquisition, and relates to a synchronous acquisition device and method for two-dimensional and three-dimensional images. Background technique [0002] The 3D scanning technology based on structured light is a high-tech integrating light, mechanical, electrical and computer technology. It is mainly used to scan the spatial shape and structure of the workpiece to obtain the spatial shape information of the workpiece surface. Among them, online high-speed scanning often uses a single camera with a structured light emitter, which is widely used because of its simple structure and fast measurement speed. The principle is that the structured light emitter is used to project the pattern onto the surface of the scanned workpiece. The camera acquires the projected pattern that is deformed due to the unevenness of the surface of the scanned workpiece, thereby obtaining the surface morphology information of the scanned work...
