Embodiment 1

[0055] Such as figure 1 As shown, a camera self-cleaning device 100 proposed in Embodiment 1 of the present invention includes: a casing 1, a transparent cover 2, and a fan 4; the opposite first side and the second side of the casing 1 are respectively provided with An opening 11 and an air hole 12, the opening 11 is in the form of a neck; the transparent cover 2 is connected to the inner wall of the housing 1 near the opening 11 to cover the opening 11, and the transparent cover 2 A plurality of ventilation holes 3 are provided at intervals between the edge of the housing 1 and the inner wall of the housing 1; the fan 4 is arranged inside the housing 1 near the second side for One side blows air; wherein, the space between the fan 4 and the transparent cover plate 2 inside the housing 1 is used to set the camera module 200, and the inner wall of the housing 1 and the camera module 200 An air duct 5 can be formed therebetween, and the air duct 5 communicates with the ventilat...

Embodiment 2

[0079] Embodiment 2 of the present invention proposes a camera system, which includes: figure 1The camera self-cleaning device 100 is shown; the camera self-cleaning device 100 includes: a casing 1, an opening 11 and an air hole 12 are respectively provided on the opposite first side and the second side of the casing 1, and the opening 11 is a constricted mouth form; transparent cover plate 2, the transparent cover plate 2 is connected with the inner wall of the housing 1 near the opening 11 to cover the opening 11, and the edge of the transparent cover plate 2 is connected with the shell A plurality of ventilation holes 3 are arranged at intervals between the inner walls of the body 1; a fan 4 is arranged inside the housing 1 near the second side for blowing air to the first side; Wherein, the space between the fan 4 and the transparent cover plate 2 inside the casing 1 is used for setting the camera module 200, and the inner wall of the casing 1 and the camera module 200 can...

Embodiment 3

[0086] Embodiment 3 of the present invention proposes a camera system control method, which is stored in the controller of the camera system in the form of a program, or stored in the general controller of the device, vehicle, or robot that uses the camera system, such as Figure 6 As shown, the camera system control method includes:

[0087] 301. Acquire a first frame of image.

[0088] Specifically, the image is obtained by the camera module through the transparent cover. The specific method for the camera module to obtain the image is known to those skilled in the art, and will not be described in detail in the embodiment of the present invention.

[0089] 302. Perform brightness detection and out-of-focus detection on the first frame of image.

[0090] Specifically, since the camera self-cleaning device protects the camera module, dust, water droplets, frost, and fog all fall on the camera self-cleaning device, especially on the transparent cover, and then the camera modu...

Abstract

The invention relates to a camera self-cleaning device, a camera system and a camera system control method, and relates to the technical field of cameras. The main technical solution is: camera self-cleaning device, which includes: housing, transparent cover plate, fan; the opposite first side and second side of the housing are respectively provided with openings and air holes, and the openings are in the form of shrinkage; the transparent cover The plate is connected to the inner wall of the housing close to the opening to cover the opening, and a plurality of ventilation holes are arranged at intervals between the edge of the transparent cover plate and the inner wall of the housing; the fan is arranged inside the housing near the second side, It is used to blow air to the first side; wherein, the space between the fan inside the housing and the transparent cover is used for setting the camera module, and an air duct can be formed between the inner wall of the housing and the camera module, and the air duct communicates with the ventilation hole And the air hole, the wind blown by the fan is blown out through the air duct and the ventilation hole in turn. Solve the technical problems that the camera lens is easily covered by dust, raindrops and frost.

Description

technical field [0001] The invention relates to the technical field of cameras, in particular to a camera self-cleaning device, a camera system and a camera system control method. Background technique [0002] As the most important sensor of self-driving cars, robots, and other smart devices, cameras are inevitably affected by weather and the environment during use, such as dust occlusion, raindrop adhesion, frost coverage, etc. These harsh environmental conditions will greatly affect The imaging quality of the camera lens affects the perception of the surrounding environment, and ultimately affects the normal and safe operation of self-driving cars, robots or other smart devices. [0003] Therefore, how to obtain a camera that can solve the problems of dust occlusion, raindrop adhesion and frosting, that is, obtain a camera with self-cleaning function, requires further research by technicians. Contents of the invention [0004] The main purpose of the present invention i...
