Abstract

The invention discloses a concrete bridge crack detection device based on digital image processing. The device is characterized by comprising a power supply module, a distance measuring module, an image obtaining module, an image processing module, a crack characteristic extracting module, and a crack information storage module. The image obtaining module and the distance measuring module are individually connected to the image processing module, and the image processing module, the crack characteristic extracting module, and the crack information storage module are sequentially connected to the power supply module. The device is safe and reliable, the detection cost is reduced, furthermore, the artificial interference factors are effectively removed, and the problems such as discontinuous images, missed photo shooting, repeated photo shooting, low detection accuracy, low detection efficiency, and the like, are solved.

Description

technical field [0001] The invention relates to the field of bridge detection, in particular to a digital image processing-based crack detection device for concrete bridges. Background technique [0002] Bridges are an important part of the transportation system. Many bridges in our country have already experienced aging phenomena. In recent years, due to the influence of overloading and overrunning, many bridges that have not been built have also encountered some problems. These bridges have some potential safety hazards, so relevant inspections of bridges are required. In the test results, the cracks at the bottom of the bridge and at the piers are one of the important indicators to indicate the quality of the bridge. [0003] For the cracks on the bottom of concrete bridges, the main detection method at home and abroad is manual detection. The implementation of the manual detection method is mainly to observe the cracks at the bottom of the bridge through a telescope, o...
