Embodiment 1

[0060] figure 1 The flow chart of the camera cleaning control method provided by the embodiment of the present application, such as figure 1 As shown, the camera cleaning control method provided in this embodiment includes the following steps:

[0061] Step 101, determine the current target camera to be cleaned.

[0062] Step 102. Determine the cleaning period of the target camera according to the synchronization signal; wherein, the cleaning period is within a period from the end of the current frame exposure to the start of the next frame acquisition.

[0063] Step 103 , cleaning the target camera within the cleaning period.

[0064] It should be noted that the camera cleaning control method provided in this embodiment may be executed by a camera cleaning control device. In practical applications, the camera cleaning control device can be realized by computer programs, such as application software, computer programs, etc., or by media that store relevant computer programs...

Embodiment 2

[0083] image 3 The flow chart of the camera cleaning control method provided by the embodiment of the present application, such as image 3 As shown, the camera cleaning control method provided in this embodiment, on the basis of the first embodiment above, step 102 specifically includes the following steps:

[0084] Step 201: Determine the acquisition start time of the current frame and the interval between acquisitions of adjacent frames according to the synchronization signal.

[0085] Step 202. Based on the acquisition start time of the current frame, determine the exposure start time of the current frame; wherein, the exposure start time of each frame is consistent with the acquisition start time.

[0086] Step 203: Determine the exposure end time of the current frame according to the acquisition start time of the current frame and the preset exposure time, and determine based on the exposure end time of the current frame and the interval between acquisitions of adjacen...

Embodiment 3

[0095] On the basis of the first embodiment above, in order to further illustrate the camera cleaning control method of the present application, step 102 includes: determining whether the exposure of the current frame has ended at the current moment according to the synchronization signal; if the exposure of the current frame has not ended , then perform the step of determining the cleaning period of the target camera according to the synchronization signal; if the exposure of the current frame has ended, then according to the synchronization signal, determine the remaining duration from the current moment to the start of the next frame acquisition; If the remaining duration reaches the preset threshold, then perform the step of determining the cleaning period of the target camera according to the synchronization signal; if the remaining duration does not reach the preset threshold, then use the next frame as the current frame And execute the step of determining the cleaning pe...

Abstract

The invention provides a camera cleaning control method, device, equipment and system, and the method comprises the steps: determining a target camera which needs to be cleaned at present, determining a cleaning time period of the target camera according to a synchronization signal, the cleaning time period being in a time period from the end of current frame exposure to the start of next frame collection, and in the cleaning time period, cleaning the target camera. According to the method provided by the invention, the time period from the end of exposure of the current frame to the start of collection of the next frame can be obtained according to the synchronizing signal, the cleaning time period of the target camera is determined in the time period, and the information of the current frame is stored in the time period and the collection of the next frame is not started, so that in the determined cleaning time period, when the target camera is cleaned, image acquisition of the target camera is not affected.

Description

technical field [0001] The present application relates to the technical field of vehicle assembly, and in particular to a camera cleaning control method, device, equipment and system. Background technique [0002] With the development of vehicle assembly technology, more and more vehicles are equipped with a vehicle-mounted camera cleaning device, so that the vehicle-mounted camera can be cleaned. [0003] At present, a common camera cleaning control method is to detect whether the camera needs to be cleaned, and if it is determined that cleaning is required, the camera is cleaned. However, cleaning the camera by using the above-mentioned camera cleaning control method will affect the image collection of the camera, thereby affecting the driving experience. Contents of the invention [0004] The present application provides a camera cleaning control method, device, equipment and system for realizing camera cleaning without affecting camera image acquisition. [0005] In ...
