Abstract

The invention discloses a camera image processing method, a codec and a storage device. The camera image processing method comprises the following steps: acquiring a camera image; determining whetherthere are a person and a vehicle exist in the camera image at the same time; detecting the speed of the person and the speed of the vehicle when there are both person and vehicle in the camera image at the same time; determining a faster one and a slower one according to the speeds; and calling an identification image program corresponding to the faster one for image identification, and then calling an identification image program corresponding to the slower one for image identification. Thus, the identification function of the identification type camera can be ensured, the identification efficiency is improved, and the identification effects for to-be-identified objects in different scenes and different reflectivity can be taken into consideration.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a camera image processing method, a codec and a storage device. Background technique [0002] With the popularization of camera intelligent recognition function, more and more cameras need to have the ability of face recognition, license plate recognition and customized recognition requirements in practical applications. In order for the camera to work normally at night, it is necessary to supplement light in the monitoring area of ​​the camera, conventionally used infrared or white light. The face features of the key recognition category are generally diffuse reflective surfaces, while the license plate features are generally strong reflective surfaces, or stronger reflective surfaces than human faces. At this time, we are faced with a technical contradiction: to ensure that the camera can recognize the farthest face at night or when the environment is dark, ...
