The invention relates to a marker recognition method based on visual detection of tower shaking. Based on the recognition of the scale in the image by the target detection network, the ratio of the non-scale area in the target bounding box to the target bounding box in the image and the scale are calculated respectively. The ratio of the part outside the bounding box of the target to the entire scale; the above two ratios are weighted and summed to obtain the recognition accuracy value of the bounding box of the target; take the smallest one of the recognition accuracy values of all target bounding boxes of the scale, then the corresponding The target bounding box is the optimal bounding box, which is the final recognition scale. The method of the present invention is based on target detection, and optimizes the image recognition scale with the best quality through the method of maximizing fitting, so as to improve the accuracy of calculating tower shaking.
Description
technical field [0001] The invention belongs to the technical field of tower foundation rings, and in particular relates to a marker identification method based on visual detection of tower shaking. Background technique [0002] At present, the detection of the inclination of the foundation ring of the wind turbine tower requires construction personnel to carry professional optical levels, squares and other equipment to perform optical tracing measurements on the bottom of the tower 8-16 times a week. This process requires one person to move the square to the calculated position. At a specific position, another person reads the ruler through the scope, and the reading needs to be recorded manually. This measurement process cannot be completed by a single person, and the calculation work cannot be completed at the measurement site. The response result can only be obtained after returning to the office and performing mathematical model calculations. Therefore, the traditional...
