Embodiment Construction
[0053] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.
[0054] The inventor found in the research that when the night vision mode is turned on, the images taken in the bright environment and the dark environment respectively have a large difference in the u component and the v component; and, in the dark environment and the night vision compensation light is turned on Next, the average value of the u component and the mean value of the v component of the pixels in the target area in the image captured by the camera are concentrated in an ...

The invention provides a control method and a device for night vision compensation lamp switch and a law enforcement instrument, and the method comprises the steps: determining an ambient light intensity value according to a light intensity value collected by a light sensor; when the ambient light intensity value is greater than a preset first light intensity value and a night vision compensationlamp is in an on state, obtaining a u component mean value and a v component mean value used for representing pixel points of a target area in an image currently shot by the camera; controlling the night vision compensation lamp to be turned off at least under the condition that the u component mean value and the v component mean value do not belong to the preset area; wherein the preset area is an area formed in a rectangular coordinate system formed by a u component mean value and a v component mean value of a pixel point of a target area in a preset test image; when the u component and thev component do not belong to the preset area in the rectangular coordinate system, the condition that the current environment is a bright environment can be accurately obtained, and therefore the problem of switching jitter of the night vision compensation lamp is solved.
Description
technical field [0001] The present application relates to the field of image processing, in particular to a control method and device for a night vision compensation light switch. Background technique [0002] When the mobile body enforcement device is performing law enforcement at night, since the light sensor detects that the environment is dark, it is necessary to turn on the night vision compensation light to start the night vision recording to ensure the capture of the picture. When the turned-on night vision compensation light encounters obstacles and reflects the light of the compensation light back to the body camera, it will cause the light sensor to misjudge that the external environment is brighter, which will cause the law enforcement recorder to turn off the night vision compensation light to stop the night vision mode. After the night vision compensation light is turned off, it will periodically cause the ambient light to be dark -> turn on the night vision ...
