The invention provides an image acquisition and detection method and device, electronic equipment and a computer readable storage medium. The method comprises the following steps: carrying out image acquisition on an environment, and carrying out target identification processing on the acquired image; when an object is identified from the collected image, detecting a brightness mean value of a target area including the object; according to the brightness mean value, determining a target exposure index required to be used when image acquisition is carried out again; carrying out image acquisition on the object in the environment based on the target exposure index, and carrying out identity detection processing according to an acquired target image containing the object. According to the invention, the image meeting the identity detection requirement can be acquired, so the identity detection efficiency and accuracy are improved.
Description
technical field [0001] The invention relates to computer image processing technology, in particular to an image acquisition and detection method, device, electronic equipment and computer-readable storage medium. Background technique [0002] With the continuous development of image processing technology, face recognition technology, as a means of identity authentication, plays an increasingly important role in application scenarios such as payment systems, attendance systems, and access control systems. Therefore, to ensure image quality, for the above applications has important meaning. [0003] Related technologies generally improve the dynamic range of camera acquisition by wide dynamic range to ensure the brightness of the acquired image. However, in the actual application process, it is found that the cost of wide dynamic range image acquisition is too high, and it still cannot provide images that meet the needs of identification under complex lighting conditions such...
