The embodiment of the present application provides a detection method and system for a plate-shaped irregular curved surface workpiece. The method includes: obtaining the standard parameter information of the workpiece to be tested from the database according to the number of the workpiece to be tested, which may include the length information corresponding to the number , width information, thickness information, and profile information; obtain the three-dimensional point cloud data information of the workpiece to be measured through the image acquisition device, and determine the measurement parameter information of the workpiece to be measured according to the three-dimensional point cloud data information of the workpiece to be measured; by comparing the measurement parameter information Determine whether the workpiece to be tested is qualified or not with the standard parameter information. It solves the technical problem that there is no effective method for measuring various parameter information of the plate-shaped irregular curved surface workpiece in the related art.
Description
technical field [0001] The present application relates to the technical fields of machine vision and data processing, and in particular, to a detection method and system for a plate-like workpiece with an irregular curved surface. Background technique [0002] With the advent of the era of intelligent production, Chinese manufacturing is gradually moving towards informatization and intelligence. The measurement system, especially the measurement of irregularly shaped large workpieces, is an important part of the quality monitoring function in industrial production. It is one of the current research hotspots to ensure that it can quickly and accurately measure various parameters of the measured workpiece. The measurement of irregular surface objects is more complicated. Since the measured surface itself cannot be used as a benchmark, the accuracy of the free-form surface is mainly measured by the contour. [0003] The methods currently used in industrial measurement of profi...
