Embodiment 1

[0026] figure 1 It is a schematic flow chart of a wiper control method provided by Embodiment 1 of the present invention. This embodiment is applicable to the control of wipers on a vehicle. The method can be executed by a wiper control device, which can be implemented by software and / or hardware form is realized.

[0027] Such as figure 1 Described, the method of the present embodiment comprises:

[0028] S110. Acquire the image of the region to be detected, and divide the image of the region to be detected into at least one subregion image to be detected according to a preset division rule.

[0029] Generally, a driving recorder is installed on a vehicle. Drive recorder is used for recording the video image and sound in the whole process of vehicle driving. The image of the area to be detected may be: an image captured on a driving recorder, an image captured by the user within a preset range, and optionally, an image of both sides of the vehicle road and the driving roa...

Embodiment 2

[0046] On the basis of the above technical solution, the target raindrop detection model needs to be trained in advance, so as to determine the probability value corresponding to each sub-region image according to the target raindrop detection model. figure 2 It is a schematic flowchart of the training target raindrop detection model provided by the second embodiment of the present invention.

[0047] Before introducing the technical solution of this embodiment, it should be noted that,

[0048] Such as figure 2 As shown, the method of the embodiment of the present invention includes:

[0049] S201. Divide the training sample set into at least two training sample subsets; use one of the sample training subsets as a current calibration sample.

[0050] Before training the raindrop detection model, obtain a preset number of sample sets, and divide the sample set into a test sample set and a training sample set according to a preset division ratio; wherein, the training sampl...

Embodiment 3

[0079] As a preferred embodiment of the above embodiment, image 3 It is a schematic flowchart of a wiper control method provided by Embodiment 3 of the present invention.

[0080] Such as image 3 Described, the method of the present embodiment comprises:

[0081] S301. Initialize.

[0082] It can be understood as starting the application and calling the pre-trained target raindrop detection model.

[0083] S302. Collect images in real time, select a focus area and divide the grid.

[0084] During the driving of the vehicle, the driving recorder installed on the vehicle can collect video images around the vehicle. The collected images of both sides of the road and the road can be used as key attention areas. The grid method is used to divide the focus area into grids to obtain at least one grid.

[0085] S303. Use the pre-trained raindrop detection model to detect the small image.

[0086] Before the images of at least one grid are input to the raindrop detection model, ...

Abstract

The embodiment of the present invention discloses a wiper control method, device, device, and storage medium. The method includes: acquiring an image of a region to be detected, and dividing the image of the region to be detected into at least one subregion to be detected according to a preset division rule image; input the images of the sub-regions to be detected into the pre-trained target raindrop detection model, and determine the raindrop probability value corresponding to the image of the sub-region to be detected; determine the total raindrop volume according to the raindrop probability value, and control it according to the total raindrop volume The wipers work. The technical solution of the embodiment of the present invention solves the technical problem that the raindrop sensor needs to be attached to the windshield in the prior art, which affects the vision and is not easy to replace when damaged, and realizes the control of the wiper according to the pre-trained raindrop detection model. The technical effect of higher efficiency and lower cost.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of device control, and in particular to a wiper control method, device, device and storage medium. Background technique [0002] The wiper is an important part of the car, which can play a role in assisting driving, thereby improving driving safety and convenience. In the prior art, there are mainly two ways to control the sweeping of the wiper. The first method requires user participation. Optionally, when the user confirms that the wiper needs to be swept, manually turn on the wiper control switch; another implementation method is: control the rotation state of the wiper motor based on the information detected by the raindrop sensor, so as to realize Control of the wipers. Common raindrop sensors are divided into light-sensitive and piezoelectric, both of which need to be pasted on the front windshield, which has a certain impact on the visual effect and is not easy to replace w...
