The invention is suitable for the technical field of automatic detection, and provides a bolt looseness detection method, terminal equipment and a storage medium, and the method comprises the steps: obtaining an image containing a bolt; extracting a to-be-detected target area image in the acquired image; performing affine transformation on the to-be-detected target area image according to the to-be-detected target area image and the first template image to generate a first target area image; performing binarization processing on the first target area image and the first template to generate asecond target area image and a second template image; and judging whether the bolt is loosened or not according to the second target area image and the second template image. According to the bolt looseness detection method, the terminal equipment and the storage medium provided by the embodiment of the invention, the second target area image is obtained by processing the acquired image, and thenthe bolt looseness is automatically detected by comparing the difference between the second target area image and the second template image.
Description
technical field [0001] The application belongs to the technical field of automatic detection, and in particular relates to a method for detecting bolt looseness, a terminal device and a storage medium. Background technique [0002] In various engineering structures such as buildings and bridges, bolts are often used to connect the internal steel structures, which has become one of the most common forms at present. However, the bolts are affected by vibration and external loads during long-term use, which will cause them to loosen. Loose bolts will result in the loss of clamping force acting on the joints of the steel structure, which will affect the stiffness of the engineering structure and bring potential danger. Therefore, timely detection of the health and working conditions of bolts plays a vital role in ensuring the normal and safe service of engineering structures. [0003] There are many methods of bolt looseness detection based on contact sensors. The bolt loosen...
