Problems solved by technology

[0002] At present, there are more and more applications of on-board sensors in the world, especially the application of cameras is becoming more and more popular. For example, in the field of automatic driving, images are collected by on-board cameras to perceive the surrounding environment information of the vehicle during driving, so as to safely control the self-driving vehicles. Driving requires high-reliability vehicle-mounted cameras to collect high-quality images, but the light intensity is constantly changing due to environmental changes, such as day, night, tunnels, culverts, bridge holes, etc. The focal length of the camera lens varies greatly. If a fixed-focus lens is used to shoot under different light intensities, the image quality will vary greatly. For example, if the fixed-focus lens is set to adapt to the light intensity during the day, the fixed-focus lens will be The image quality of the night shot is poor; if the fixed focus lens is set to adapt to the light intensity of the night, the image quality of the fixed focus lens is poor in the daytime

Embodiment 1

[0026] see figure 1 , is a schematic structural diagram of a vehicle-mounted image acquisition system in an embodiment of the present invention, the system includes a controller 1, a plurality of cameras 2 respectively connected to the controller 1, a light sensor 3, and an encoder 4, wherein:

[0027] The controller 1 is used to receive the light intensity of the current environment from the light sensor 3; select a camera suitable for the light intensity from the plurality of cameras 2 as the target camera; when the current working camera is different from the target camera, At the same time, turn on the target camera and turn off the current working camera, and use the target camera as a working camera to collect images; and, for receiving images collected by the working camera, and sending the received images to the encoder;

[0028] The encoder 4 is used to encode the received image and transmit the encoded image.

[0029] In the embodiment of the present invention, if t...

Embodiment 2

[0054] Based on the same concept as the vehicle-mounted image acquisition system provided in the first embodiment, the second embodiment of the present invention provides a vehicle-mounted image acquisition method. The method is as follows: Figure 7 shown, including:

[0055] Step 701, obtaining the illumination intensity of the current environment;

[0056] Step 702: Select a camera suitable for the illumination intensity from the plurality of cameras as a target camera;

[0057] Step 703, when the current working camera is different from the target camera, turn on the target camera and turn off the current working camera, and use the target camera as the working camera to capture images;

[0058] Step 704: Encode the image collected by the working camera, and transmit the encoded image.

[0059] Preferably, in an example, in step 703, turning on the target camera and turning off the current working camera may specifically include steps A1 to A3, such as Figure 8 shown, ...

Abstract

The invention discloses an image collection system and method for a vehicle-mounted terminal, so as to improve the quality of an image collected by the vehicle-mounted terminal. The system comprises acontroller, multiple cameras, a light sensor and an encoder, whereinthe multiple cameras, the light sensor and the encoder are connected with the controller respectively, and the controller is used for receiving the illumination intensity of a current environment from the light sensor, selecting one camera adapted to the illumination intensity from the multiple cameras to take as a target camera,and when a current working camera is not the same as the target camera, turning on the target camera and turning off the current working camera, and taking the target camera as the working camera tocollect an image, and is used for receiving the image collected by the working camera and sending a received image to the encoder; and the encoder is used for encoding the received image and transmitting an encoded image.
