Abstract

The invention relates to the technical field of dam body crack detection, and discloses a dam image crack detection device and method based on binocular vision, and the method comprises the steps: original image collection, image processing, crack position determination, crack length and width calculation, and the like. According to the technical scheme, a basic method for calculating the length and the width of the crack by utilizing an image acquired by the visible light camera and detecting the length and the width of the crack based on a binocular vision technology is used, so that the accuracy is higher.

Description

technical field [0001] The invention relates to the technical field of crack detection, in particular to a binocular vision-based dam image crack detection device and method. Background technique [0002] After the dam is used for a long time, due to the action of water erosion, erosion, etc., cracks will be formed and cause leakage, which will cause serious safety hazards to the safety of the dam. Therefore, it is necessary to regularly detect the cracks in the dam. The current situation of dam crack detection is mainly manual, relying on large machinery such as inspection trucks to send special equipment for bridge detection to the dam body, looking for cracks with the naked eye and measuring the crack size with a special crack observer or ruler. This manual detection method is inefficient, costly and has potential safety hazards. [0003] With the development of UAV technology, the advent and application of various types of high-precision sensors and high-performance ele...
