Problems solved by technology
The problem with this method is that there is no sign set for detection on the edge of the canopy that has been built, and only human eyes can be used for detection and estimation, and the accuracy is not high
[0005] At present, there is no stable and mature set of methods for vibration detection of canopy at high-speed rail stations

Embodiment Construction
[0029] The technical solution of the present invention will be further described in conjunction with the accompanying drawings. Such as figure 1 As shown, the technical steps of the high-speed rail station canopy vibration detection method based on video and image registration involved in the present invention include:
[0030] S1. Detection location selection
[0031] Determine the detection point of the awning on the awning to be detected, and then select the corresponding detection position on the ground. The detection position is selected to maintain stability and avoid occlusion, and the angle between the line between the detection position and the canopy detection point and the horizontal plane is between ±45°. After the detection position is determined, the distance D between the detection position and the detection point is measured by a laser range finder.
[0032] S2. Layout of detection marks
[0033] Aim the laser rangefinder at the detection point on the canop...

The invention discloses a high-speed rail station canopy vibration detection method based on video and image registration. A high-speed rail station canopy vibration video is recorded, the automatic image registration technology is adopted to register decomposed video frames, vibration detection signs are automatically recognized from the registered images, and therefore canopy vibration detection is achieved. The high-speed rail station canopy vibration detection method comprises the technical steps of detection position selection, detection sign layout, canopy vibration detection video obtaining, video decomposition, image registration, canopy vibration amplitude calculation and vibration curve drawing. According to the high-speed rail station canopy vibration detection method, on the basis of the characteristics of canopy vibration, the movement detection signs are laid on the ground to record the canopy vibration video, and canopy vibration detection is achieved in a non-contact mode.
Description
technical field [0001] The invention relates to a high-speed rail station equipment detection technology, in particular to a high-speed rail station canopy detection technology. Background technique [0002] my country's high-speed railway has developed rapidly in recent years, gradually forming a high-speed rail transportation network that radiates across the country. The operating mileage of high-speed rail has ranked first in the world, which greatly facilitates people's travel. More and more people choose to travel by high-speed rail. At the same time , the operation safety of high-speed rail has also been paid more and more attention. [0003] The high-speed rail station is one of the most critical links in the operation of the high-speed rail, and it is also the place with the densest population flow. In order to provide more space for activities on the platform, avoid wind and rain from disturbing passengers and locomotives on the platform, and at the same time satisf...
