Parameter adjustment method and device of image collector, equipment and storage medium

Abstract

The embodiment of the invention discloses a parameter adjustment method and device of an image collector, equipment and a storage medium. The parameter adjustment method of the image collector comprises the steps of determining a target image block in an image and a brightness type of the target image block according to brightness information of at least two image blocks in the image collected by the image collector; determining the position region type of the target image block; and according to the brightness type and the position region type of the target image block, determining a brightness parameter adjustment strategy of the image collector for adjusting the brightness parameter of the image collector and / or an image collected by the image collector. According to the embodiment of the invention, the brightness parameter is adaptively adjusted according to different brightness and different positions of the monitored object in the image collected by the image collector, and the quality of the image collected by the image collector is integrally improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of monitoring, and in particular to a parameter adjustment method, device, device and storage medium of an image collector. Background technique [0002] The rapid development of surveillance technology has allowed cameras to enter thousands of households, and at the same time put forward higher requirements for cameras. The full-color camera can accurately restore the color of the object at night, and the picture is more vivid and vivid. However, limited by the light-sensing performance of the sensor, full-color cameras must show better image effects in dark environments, and supplementary light must be added to enhance the brightness of the foreground to ensure that the collected images are clear. [0003] In the existing automatic light supplement technology, the image acquisition sensor acquires the image data of the scene environment, forms an image histogram through calculati...

Problems solved by technology

[0004]However, the histogram cannot accurately reflect the brightness value of the current image, so adjusting the fill light intensity according to the histogram cannot match the real brightness of the image well

In addition, this solution needs to collect some empirical data, the steps are cumbersome and interfered by empirical values, resulting in a mismatch between the intensity of the fill light and the brightness value of the image, and the quality of the collected image is poor
