Referring to fig. 5, the method may specifically include the following steps:
and S501, receiving a tire induction signal from an induction sensor to start the current detection equipment.

That is, when starting switch received tire response signal, vision camera detector began work, and after the tire passed through, vision camera detector learnt the tire through the tire data that the backstage surveyed that the detection zone has been crossed to the tire, and then vision camera detector automatic shutdown work. The start-stop design of the visual camera detector is not only used for protecting the working life of the visual camera detector, but also used for ensuring that data acquired by the visual camera detector during working is pattern data of a required tire, so that the phenomenon that the visual camera detector acquires excessive useless data to influence the processing of a background software algorithm is avoided. The controller receives three-dimensional coordinate data from the vision camera detector when the tire to be detected passes through the detection area, and generates a simulated sectional view according to the three-dimensional coordinate data.

Specifically, the pattern depth is predicted through two times of detection, for example, the vehicle runs 30000km in the last detection, and the tire pattern depth is 18 mm; at this time of detection, the vehicle has traveled 50000km, and the pattern depth is 17mm, and assuming that the tire replacement criterion is that when the pattern depth is 1mm, the number of miles that can be traveled continuously is (50000 + 30000)/(18-17) × (17-1), and the number of miles that can be traveled continuously is 320000 km.
