Passenger car tire balance point identification system

Abstract

The invention provides a passenger car tire balance point identification system, thereby solving a technical problem that the existing equipment can not be upgraded and modified by the existing spot mark detection scheme in the prior art. The system comprises a conveyor belt, a photoelectric switch, an illumination source, a camera, an image analysis module and a comparison analysis module. The photoelectric switch includes a light-emitting assembly and a receiving assembly that are arranged at the two sides of the conveyor belt; the photoelectric switch is connected to the camera and triggersthe camera to work; the illumination source and the camera are arranged above the conveyor belt; and the illumination source and the camera work cooperatively. According to the system provided by theinvention, the camera is controlled by the photogate to work; and the structure is simple and the cost is low. A few of devices are installed for the conveyor belt and modification of most of existing spot mark devices can be realized. The camera exposure time is short and the picture definition is improved; with an HSV color model, the work difficulty of the image analysis module is reduced andthe working efficiency of the image analysis module is improved; and because of an externally arranged processing module, remote control of the identification system is realized.

Description

technical field [0001] The invention relates to the field of image recognition, in particular to a passenger car tire balance point recognition system. Background technique [0002] In the process of purchasing tires, passenger vehicle manufacturers usually require tire manufacturers to perform dynamic balance experiments on the tires and mark the balance point on the side of the tire. The mark is usually a red, white or yellow circular or ring pattern . However, due to some uncontrollable factors in the production process, these dot marks have various abnormalities, such as curling, rollover, damage, etc. From the appearance point of view, these circles are deformed or missing. [0003] Existing equipment only has the ability to mark, and cannot detect whether the mark is intact. In the prior art, due to the small installation space of the existing equipment, it is difficult to transform, and the detection scheme of the mark is only applicable to the production of the mark...
