Problems solved by technology

This method often needs to manually install the target on the structure. Although the cost of the sensor is saved, it is difficult to avoid the danger and complicated labor of manual installation. The labor cost is still high, and there are also problems such as poor target recognition effect.

Embodiment Construction

[0038] Specific technical solutions of the present invention will be described in connection with examples and drawings.

[0039] A method of disoburious target transmission tower based on computer vision, such as image 3 As shown, including the following steps:

[0040] Step 1: Select the appropriate camera according to the environment of the electrified electric tower, build the equipment, require the camera to shoot video clarity is not less than 4K, the frame rate is not less than 60 frames, select the transmission tower to be tested (ie, the region) and the inner angle point. The camera focusing the camera to the transmission tower is taken to take a video of the transmission tower to generate vibration and displacement structure deformation, transfer the video to the computer. like figure 2 , C is the region of interest, B is the inner corner point.

[0041] Step 2: Gray grayscale, binctification processing by frame by the computer.

[0042] Step 3: Use computer to identify ...

Abstract

The invention provides a target-free power transmission tower displacement and vibration identification method based on computer vision. The method comprises the steps of: employing a camera to shoot a video of vibration and displacement generated by an external force of an electric tower, and employing a computer to carry out the frame-by-frame processing of the video shot by the camera; through image graying, binarization processing, inner contour detection, feature contour screening, electric tower to-be-detected part image interception, key point detection and the like, obtaining the coordinates of a specific inner corner point of an electric tower feature contour, and tracking the inner corner point to identify displacement and vibration conditions of a power transmission tower; and finally, calculating a scale factor of conversion from pixels to a real distance by using the structural size of the power transmission tower, and calculating the real distance of displacement of the power transmission tower. The structure safety detection of a power transmission tower is realized by using equipment such as a camera and a computer and adopting a non-contact measurement method, so that the detection efficiency is improved, the rapid, safe and efficient inspection of a power transmission tower can be realized, and the manpower and sensor cost is reduced to a great extent.

Description

Technical field [0001] The present invention provides a method based on computer vision-free target transmission tower displacement sensing identification method, belonging to the field of computer visual technology. Background technique [0002] The total number of 220kV and above the service tower has exceeded 200,000, and the main support structure of the transmission line is an important energy engineering infrastructure. In order to ensure the safe operation of the transmission tower, extend its service life, must regularly perform structural health testing and maintenance of the transmission tower. In the structural health test of the power transmission tower, the vibration and structural deformation displacement of the transmission tower are not important. [0003] The method of measuring the vibration and structural deformation displacement of the transmission column has two types of contact and non-contact formula. The contact method often needs to install a large number...
