Problems solved by technology

[0004] However, when the infrared strobe device is used for supplementary light, the image captured by the camera will appear color cast or black and white, which is not conducive to the driver's behavior and vehicle structured information (vehicle structured information can include body color, license plate Information, etc.) for analysis, does not meet the current traffic checkpoint camera requirements

Abstract

The invention provides an image acquisition method and system. The image acquisition method provided by the invention comprises the following steps: controlling a camera to switch between a first working mode and a second working mode according to an event detection result; in the first working mode, receiving visible light flashing supplementary light, and controlling a first image sensor to perform visible light image acquisition; in the second working mode: receiving visible light non-explosion flash light supplement and infrared light supplement, controlling the first image sensor to perform visible light image acquisition, controlling the second image sensor to perform infrared image acquisition, and performing fusion processing on the visible light image and the infrared image. According to the image acquisition method and system provided by the invention, the image acquisition method simultaneously suitable for night and daytime can be provided, so that the problem of light pollution or the problem that the obtained snapshot image does not meet the requirement can be avoided.

Description

technical field [0001] The present application relates to the technical field of image acquisition, and in particular to an image acquisition method and system. Background technique [0002] Cameras for traffic checkpoints are used to collect and capture video images of passing vehicles. When capturing, it is generally required to be able to obtain information such as license plate color, license plate number, body color, and driver’s face information in the vehicle. When taking pictures, the traditional method is to use a camera with a visible light strobe device. The visible light strobe device is mainly used to shine light through the front windshield of the vehicle into the car for supplementary light. [0003] When the visible light strobe device is used for supplementary light, the visible light has light pollution at night, which will affect the driver and cause driving safety hazards. In order to avoid the above problems, in recent years, infrared light strobe devic...
