Testing system and testing method for tire slip amount based on edge-enhanced recognition

Abstract

The invention discloses a testing system for tire slip amount based on edge-enhanced recognition. The testing system comprises a test bed and a work station, wherein the test bed comprises a glass bedplate and a framework arranged on the glass bed plate; a tire is arranged in the framework; a rolling control device is connected to the tire; lasers are arranged on the framework side walls which are in front-back correspondence along the rolling direction of the tire; a circle of LED illuminating lamps are arranged below the glass bed plate in a mode of enclosing a contact surface between the tire and the glass bed plate; a camera is arranged at a position, opposite to the contact surface between the tire and the glass bed plate below the glass bed plate; the work station is in data connection with the LED illuminating lamp and the camera, and is used for receiving image data, as well as processing and displaying the data. The testing system disclosed by the invention has the advantagesthat the discrimination precision of tire contact and off-ground time is improved, detection precision and test repeatability of the wear testing system are improved, and the test for static imprintand dynamic slip can be realized; the testing system has the advantages of higher functional expansibility, simple operation, good repeatability and high test precision.

Description

technical field [0001] The invention relates to tire slippage testing, in particular to a tire slippage testing system and testing method based on edge enhancement recognition. Background technique [0002] The wear of tires in actual use is one of the most concerned factors for vehicle safety. Indoor tire abnormal wear testing and analysis technology has been widely used in the production and testing of tire companies, but how to quickly, accurately and effectively analyze tire abnormal wear is still an important direction for the development of tire wear testing technology at home and abroad. [0003] At present, the existing technical methods are as follows: the patent publication number is CN206496732U, and the patent name is a rolling tire tread slip measurement system. In this patent, it is mentioned that the displacement method wear test system of the tire friction energy testing machine based on vision is mainly through the Pre-defined marking points on the tire, an...
