Abstract

The invention relates to a tread pattern depth measuring device and method and a computer readable storage medium, and belongs to the technical field of machine vision measurement, the tread pattern depth measuring device comprises a measurement supporting device, wherein the interior of the measurement supporting device is hollow, and a measuring port is formed in the measurement supporting device; a detection device which is arranged on the measurement supporting device; an imaging device which is arranged in the measurement supporting device and used for emitting an imaging light beam to the tire located at the measurement opening in the top wall, wherein a tread pattern image of the tire is formed after the imaging light beam is reflected; a control processing device which comprises acontrol sub-module and a processing sub-module; the control sub-module which is used for responding to a measurement starting signal sent by the detection device and controlling the imaging device andthe image acquisition device to work; and the processing sub-module which is used for carrying out image processing on the received tread pattern image to obtain the depth data of the tread pattern.Compared with the prior art, the device has the effect of improving the measurement accuracy of the tread pattern depth data.

Description

technical field [0001] The present application relates to the field of machine vision measurement technology, in particular to a tire tread depth measurement device, method and computer-readable storage medium. Background technique [0002] Tire tread pattern, also known as tread pattern, its main function is to increase the friction and drainage capacity between the tread and the road surface, so as to improve the driving performance of the tire, and also increase the aesthetics of the tire. In order to ensure the driving safety of the car, the amount of wear of the tires in use is generally limited. [0003] Measuring the depth of the tread pattern is a straightforward method of evaluating tire wear. At present, life usually uses a hand-held tread pattern depth gauge tool or a hand-held laser depth measuring instrument to manually measure the depth of the tread pattern one by one, and the measured data is saved by manual recording or wireless transmission. In order to im...
