Abstract

The present application provides an image processing method and device, which are applied to video cameras. The method includes: adjusting the exposure of the color image sensor based on the first original preview image collected by the color sensor; The second original preview image collected at the same time, adjusts the exposure of the black and white image sensor through the infrared supplementary light device; respectively obtains the first effective preview image and the second effective preview image collected by the exposure adjusted color image sensor and the black and white image sensor simultaneously , wherein, the first effective preview image clearly displays the road environment information, and the second effective preview image clearly displays the license plate information of the vehicle driving on the road; the first effective preview image and the second effective preview image are synthesized to obtain The output target image can realize the complete monitoring of the road monitoring area and improve 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...
