The present invention is applicable to the field of computer technology, and provides a method, device, equipment, and storage medium for detecting abnormal switching of a day-night camera device. The method for detecting abnormal switching of a day-night camera device includes: acquiring a differential image, which is before and after the action of a filter The difference image between the images collected by the camera device; the feature map between the single layers of the difference image: Y=R×k+G×m+B×n, where R, G, and B are the difference images respectively The data obtained by single-layer separation, k, m, and n are the coefficient values preset according to the training results; the sparse algorithm is used to judge whether the switching of the day-night camera device is abnormal according to the feature maps between the single layers of the difference image. This scheme constructs the feature map between each single layer of the differential image, and then judges whether the switching of the day and night camera device is abnormal through the sparse algorithm according to Y. Compared with manual detection of whether the switching of the filter is abnormal, the detection efficiency is effectively improved and the Labor cost.
Description
technical field [0001] The invention belongs to the field of computer technology, and in particular relates to a method, device and storage medium for detecting abnormal switching of a day-night camera. Background technique [0002] A day and night type camera is a camera that can be used both day and night. A filter switching device, such as an IR-CUT double filter switching device, is generally used in a day-night camera device to perform filter work. The specific workflow of the filter switching device is: during the daytime, switch the filter to filter out infrared light to ensure the imaging effect of the image; during the nighttime, remove the filter to ensure full spectrum transmission and improve the brightness of the image. . However, during the use of the day-night camera device, due to environmental factors, poor hardware materials, or aging of the device, the filter switching device may switch abnormally. [0003] In the prior art, whether the filter switching...
