Problems solved by technology

However, different vehicles have different situations of mud, and the time of automatic water spraying is difficult to control. If a shorter water spraying time is uniformly set, some vehicles cannot be rinsed clean; if a longer water spraying time is uniformly set, it will lead to waste of water

Embodiment 1

[0034] Embodiment 1 of the present invention provides a wheel state recognition method, through which the cleaning state of the wheel can be automatically recognized, and then the water spray switch for cleaning the wheel is controlled according to the recognized cleaning state, specifically, figure 1 It is a flow chart of the wheel state recognition method provided in Embodiment 1 of the present invention, such as figure 1 As shown, the wheel state recognition method provided in this embodiment includes the following steps S101 to S105.

[0035] Step S101: Acquire vehicle images.

[0036] Optionally, when the wheels are being washed, the vehicle is parked at a fixed location, and a camera is set at the location to take pictures during the wheel cleaning process and obtain images of the vehicle. Or, it is also possible to shoot a video of the vehicle in real time during the wheel cleaning process, and extract frame images therein to obtain a vehicle image.

[0037] Step S102...

Embodiment 2

[0063] Embodiment 2 of the present invention provides a water spray control method, through which, the cleaning status of the wheels can be automatically identified, and then the water spray switch for cleaning the wheels can be controlled according to the identified cleaning status, specifically, Figure 4 The flowchart of the water spray control method provided by Embodiment 2 of the present invention, such as Figure 4 As shown, the wheel state recognition method provided in this embodiment includes the following steps S201 to S202.

[0064] Step S201: Identify the washing status of the wheels.

Abstract

The invention provides a wheel state recognition method and device and a water spraying control method and device. The wheel state recognition method comprises the following steps: acquiring a vehicle image; detecting a front image of a wheel in the vehicle image; extracting a wheel contour in the front image; calculating a soil area in the wheel contour; and determining the cleaning state of the wheel according to the size of the soil area. According to the vehicle wheel cleaning device, cleaning control can be carried out, so that waste of water resources is reduced while the vehicle wheel is washed clean.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a wheel state recognition method and device, and a water spray control method and device. Background technique [0002] At present, the domestic air pollution is serious, among which, the dregs and dust generated by construction sites are one of the main causes of air pollution. Slag dust pollution is the unorganized particle pollution generated during the construction process. It includes not only the dust caused by various construction links inside the construction site, but also the mud trucks carrying mud on the road and the dirt trucks dripping on the roads outside the construction site. The resulting secondary traffic raises dust. [0003] In order to solve the above-mentioned secondary traffic dust, many construction sites in cities have installed vehicle washing stations, but it is still impossible to avoid the problem of vehicles carrying mud on the road. On t...
