Abstract

The invention provides an image processing method and device applied to a camera, and the method comprises the steps: carrying out exposure adjustment of a color image sensor based on a first originalpreview image collected by the color sensor; based on the first original preview image and a second original preview image collected by the black-white image sensor at the same moment, carrying out exposure adjustment on the black-white image sensor through an infrared light supplementing device; acquiring a first effective preview image and a second effective preview image which are collected bythe color image sensor and the black-and-white image sensor at the same time after exposure adjustment, wherein the first effective preview image clearly displays road environment information, and the second effective preview image clearly displays license plate information of vehicles running on a road; and synthesizing the first effective preview image and the second effective preview image toobtain a target image for output, thereby realizing complete monitoring of the road monitoring area and improving the monitoring effect of the camera.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to an image processing method and device. Background technique [0002] At present, in the field of intelligent transportation, in order to ensure that the captured images can clearly identify information such as vehicle outlines and license plates, road surveillance cameras are generally used in conjunction with supplementary light equipment such as fill lights, strobe lights, or exposure lights. With the assistance of various supplementary light equipment, the traffic camera can capture the vehicles on the road to obtain a clear image. [0003] Existing road monitoring cameras mainly use the exposure flash light in the visible light band to capture images, or use the constant light in the visible light band to fill in the light on the license plate to make the image imaging obtain a clear license plate or other vehicles. information. However, no matter whet...
