Embodiments of the present application provide an exposure adjustment method, device, computer-readable storage medium and electronic equipment, which relate to the field of image processing. The method includes: detecting a target area conforming to the target feature in an image captured by the camera device; when the target area is detected, adjusting the exposure target value of the camera device according to the brightness value of the target area; A first auxiliary area conforming to a first preset feature is detected in the image; the first auxiliary area includes a target area; when the first auxiliary area is detected, an exposure target value of the imaging device is adjusted according to the brightness value of the first auxiliary area. The present application can adjust the exposure of the camera device stably and accurately, so as to improve the recognition rate of the content in the target area.
Description
technical field [0001] The present application relates to the field of image processing, in particular, to an exposure adjustment method, device, computer-readable storage medium and electronic equipment. Background technique [0002] Surveillance camera equipment such as electric police and checkpoints can record road traffic conditions in real time and provide protection for people's travel safety. It usually takes road images continuously in real time, and then detects the license plate numbers of vehicles in the road images. [0003] However, in scenarios such as forward lighting and backlighting, although the exposure of the entire picture captured by the monitoring camera equipment is normal and the brightness is appropriate, the brightness of the license plate of the vehicle may be overexposed or underexposed. This will cause these over-exposed or under-exposed license plates to not be recognized correctly. At this time, if there is a traffic incident in violation o...
