The memories are used to store computer programs (e.g., applications, functional modules, etc. that implement the above-described methods), computer instructions, etc., which may be stored in partition in the memory or memories. And the computer programs, computer instructions, data, etc. described above may be invoked by a processor.
The computer programs, computer instructions, etc. described above may be stored in one or more memories in a partitioned manner. And the computer programs, computer instructions, data, etc. described above may be invoked by a processor.
A processor for executing the computer program stored in the memory to implement the steps of the method according to the above embodiments. Reference may be made in particular to the description relating to the preceding method embodiment.
The processor and the memory may be separate structures or may be an integrated structure integrated together. When the processor and the memory are separate structures, the memory, the processor may be coupled by a bus.
The computer-readable storage medium can be used for executing the camera cleaning method described in any one of the foregoing embodiments when the computer program stored thereon is executed by the processor, and the camera can be cleaned timely and automatically by first acquiring image data of the camera, judging whether dirt exists on the surface of the camera according to the image data, and after the dirt is determined, spraying high-pressure gas to the surface of the lens of the vehicle-mounted camera through the gas outlet nozzle surrounding the surface of the lens. In addition, high-pressure gas is used as a cleaning medium, so that the cleaning agent can be directly supplemented by external air after cleaning every time, special water storage and pipelines are not needed, water supplementing operation in a fixed period is not needed, and the cleaning agent is easier to maintain.
It is to be understood that the invention is not limited to the examples described above, but that modifications and variations may be effected thereto by those of ordinary skill in the art in light of the foregoing description, and that all such modifications and variations are intended to be within the scope of the invention as defined by the appended claims.
