Problems solved by technology
The invention discloses a tire pattern depth rapid measurement device, which comprises a shell, a calculation unit, a camera, a switch, a first reflecting mirror, a second reflecting mirror and a laser, and is characterized in that: the laser and the camera are horizontally arranged in the shell and are parallel to each other; and the first reflecting mirror and the second reflecting mirror are respectively arranged at positions opposite to the laser and the camera, the angle between the first reflecting mirror and the horizontal direction is 45 degrees and is not changed, the angle between the second reflecting mirror and the horizontal direction is adjustable between 50 degrees and 80 degrees, the shell is provided with a window above the first reflecting mirror, a switch is arranged at the upper part of the shell and is positioned in front of the window, the calculation unit is in communication connection with the camera and the laser through signal lines and used for controlling the camera and the laser to work and operating data, and the switch is connected with the computing unit and used for controlling the laser and the camera to work. The position of the groove of the pattern can be accurately and effectively extracted based on a calculation method of a local threshold. The whole device has the advantages of being accurate in measurement, small in error, simple in structure and capable of greatly reducing the size of detection equipment.
