After the elevator runs for a long time, the traction wheel groove will be excessively worn. If the wheel groove is worn to a certain extent and is not replaced, it will be dangerous. In practical application, it is found that the wear between the wheel grooves of the traction wheel is not uniform. Therefore, the traction wheel needs to be tested regularly for replacement. The detection methods in the prior art have high requirements for inspectors and rich experience; Secondly, the 1.25 times braking test requires the handling of weights, which is time-consuming and laborious, and the braking test has the possibility of no legal stop of the lift car, which has serious potential safety hazards. Moreover, the current inspection is only the confirmation of the traction wheel wear results, which cannot monitor the traction wheel wear process, nor predict the remaining service life of the traction wheel, that is, how long it can be used. With the development of visual recognition technology, it is possible to detect the traction wheel by visual recognition. The wheel groove part is reconstructed by visual recognition, and then the wear degree of the wheel groove can be analyzed. However, if 3D reconstruction is needed, the target needs to be photographed from multiple angles through the camera, which is far away from human eyes. Therefore, for the immovable camera, at least two cameras are required, but the angles between the two cameras, between the cameras and between the whole camera support and the installed elevator need to be accurately adjusted.
