Abstract

The invention is suitable for the technical field of image processing, and provides a defect detection method and device, and terminal equipment. The method comprises the steps: obtaining a two-dimensional image and a depth image of a detected object; performing image processing on the two-dimensional image to obtain first defect information of the measured object; performing image processing on the depth image to obtain second defect information of the detected object; and acquiring target defect information contained in the first defect information and the second defect information, and identifying the target defect information as defect information of the measured object. The defect detection method is an automatic detection method, equipment such as scaffolds does not need to be erected, the safety risk, the inspection cost and the engineering quantity are reduced, and the detection efficiency is improved; the regular inspection requirements can be met; errors caused by subjectivejudgment during human eye observation and detection are avoided, so that the detection accuracy is improved. Moreover, two different images are compared to obtain a detection result, and the detectionaccuracy is further improved.

Description

technical field [0001] The present application belongs to the technical field of image processing, and in particular relates to a defect detection method, device and terminal equipment. Background technique [0002] Generally, the gates of hydropower stations are controlled by hydraulic hoists. After several years of operation, the surface of the piston rods of these hoists has a certain degree of corrosion. If the piston rod is corroded to a certain extent, it will damage the sealing performance of the oil cylinder during operation. Moreover, the pollutants that have been corroded and fallen off will also pollute the oil, and even lead to the blockage and failure of the control valve, which will eventually cause the hoist to fail to open and close normally. . Therefore, it is necessary to frequently inspect the appearance and corrosion of the piston rod of the hydraulic hoist. Due to the special space environment where the piston rod of the hydraulic hoist is located, and...
