Abstract

The invention discloses a handheld linear structured light tire wear detection device, which comprises a shell and a front shroud, a laser emitter and a camera are arranged in the shell; a C-shaped sliding rail and a flexible cloth curtain hoop are arranged at the front end of the front protective cover; the C-shaped sliding rails are symmetrically distributed at the front end of the front protective cover up and down; the flexible cloth curtain hoop is connected with the C-shaped sliding rail in a sliding manner; an edge wing strip is arranged at the rear end of the flexible cloth curtain hoop; curtain hanging points are arranged on the side wing strips and the front protective cover, the flexible light shielding curtain is fixed to the two sides of the front protective cover through thecurtain hanging points on the front protective cover and the curtain hanging points on the flexible cloth curtain hoop and can be adjusted along with adjustment of the U-shaped flexible cloth curtainhoop, interference of external light on image collection can be avoided, and the image collection quality and the device stability are improved. A structured light vision measurement method is adoptedto extract the depth of the tire pattern, the precision is high, light strip feature image information extraction is simple, the real-time performance is high, and active control is achieved.

Description

technical field [0001] The invention relates to the field of structured light visual measurement, in particular to a hand-held linear structured light tire wear detection device and a detection method. Background technique [0002] As the only part of the car in contact with the ground, tires are very fragile and belong to the "vulnerable parts" of car parts. Among them, the pattern of the tire plays a vital role in the driving process of the car. The pattern of the tire can increase the friction between the tire and the ground, remove water, improve the braking performance and handling performance of the vehicle; help the tire dissipate heat and reduce the The probability of damage; reduce tire noise, enhance driving comfort, etc. Therefore, tire pattern wear detection is a necessary work for car owners or personnel in the car service industry. [0003] Most of the existing tire wear detection methods rely on visual observation or measurement with vernier calipers, etc., ...
