Abstract
The invention discloses a fill light lamp automatic control method based on video analysis. The fill light lamp automatic control method based on the video analysis achieves the automatic control over a fill light lamp according to the changing of brightness values in a monitoring area. The fill light lamp automatic control method based on the video analysis achieves the self-adaptive control over the fill light lamp according to the changing of ambient brightness, avoids electric energy waste and light pollution to the environment by the fill light lamp, avoids the phenomena that the definition of monitoring video images declines due to insufficient light and the fill light lamp may flicker, saves equipment investment, shortens mounting construction cycles, and improves the reliability of system working.
Description
Technical field
The present invention relates to the technical field of video monitoring regional light compensating lamp, specifically a kind of light compensating lamp autocontrol method based on video analysis.
Background technology
Be accompanied by socio-economic development, in social security strick precaution, control of traffic and road field, the application of video monitoring system is more and more universal, in order in the situation that night or illumination are bad, to guarantee that video image has enough definition, need to adopt light compensating lamp to provide illumination to video monitoring regional, light compensating lamp becomes an important component part in video monitoring system.Control to light compensating lamp in video monitoring system has two kinds of methods, and the one, fixed time, open or close light compensating lamp in the predefined time of system; The 2nd, adopt the light sensor ambient light, open light compensating lamp when illumination is not enough, close light compensating lamp when illumination is sufficient.
Fixed time can't meet the light filling needs in weather condition sudden change situation, as the dark that before the heavy rain arriving, dark clouds are bearing down on the city. causes; And because weather replaces, the daybreak of a local every day, day dark asynchronism(-nization), fixed time is prone to that to open the light compensating lamp time excessively slow, affect video monitoring system and gather picture rich in detail, or it is too early to open the light compensating lamp time, causes the meaningless loss of electric energy, brings ambient light contamination.
The light sensor method can effectively make up the deficiency of fixed time, but most light sensors installation site is not in the zone of video monitoring, can not accurately reflect the brightness of guarded region, and be subject to after ambient dust is polluted opening light compensating lamp all day, both cause the huge waste of electric energy, brought extra light pollution to environment again.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of light compensating lamp autocontrol method based on video analysis, variation according to brightness value in guarded region, the autocontrol method of realization to light compensating lamp, guarantee video monitoring system by day, image that all can clear acquisition monitoring zone under night and sudden change weather conditions.
Technical scheme of the present invention is:
A kind of light compensating lamp autocontrol method based on video analysis specifically comprises the following steps:
(1), the video image in the camera acquisition guarded region, and be sent in real time embedded host;
(2), embedded host receives the video image that video camera transmits, and analyzing and processing obtains the real-time luminosity value of guarded region;
(3), embedded host reads the current state of light compensating lamp in real time, if light compensating lamp is " unlatching " state, and the real-time luminosity value of guarded region is greater than while closing threshold value, closes light compensating lamp; If light compensating lamp is " closing " state, and the real-time luminosity value of guarded region is less than while opening threshold value, opens light compensating lamp; Wherein, close threshold value and be greater than the unlatching threshold value.
Described embedded host is determined the ambient brightness analyzed area after processing the guarded region video image of camera acquisition, reduces the operand needed while processing; Then the video image in Luminance Analysis zone is converted to corresponding grey scale signal, obtains the single frames brightness value of guarded region after average; Finally, impact brightness value detected for eliminating environmental interference and noise of equipment, embedded host adopts the method for multiframe smothing filtering to obtain the real-time luminosity value of guarded region.
The power supply of described light compensating lamp is connected to the output contact of relay circuit, and level shifting circuit is converted to the level signal that drives relay circuit to the level signal of embedded host output; When being output as high level signal, open light compensating lamp, when being output as low level signal, close light compensating lamp.
Described video camera, embedded host, level shifting circuit, relay circuit are arranged in same protective cover.
Advantage of the present invention:
(1), the present invention is according to the variation of ambient brightness, realizes in video monitoring system the adaptive control of light compensating lamp is opened to light compensating lamp when luminance shortage, closes light compensating lamp when brightness is good;
(2), the ambient brightness that gathers of the present invention is by Video Analysis Technology, takes from the real-time video of monitoring scene, the brightness value obtained accurately, reliable;
(3), to take high-performance ARM/DSP chip be processor in the present invention, in monitoring scene, select a zone that not blocked by external object as the Luminance Analysis zone, reduce operand when embedded host carries out video analysis, reduced the requirement to the embedded host performance;
(4), the present invention avoided the waste of energy of light compensating lamp and the light of environment disturbed, and also avoided the monitor video image to descend because of the definition that the illumination deficiency causes;
(5), the present invention is without extra light sensor is installed, and saved equipment investment and installation cycle, improved the system works reliability;
(6), the present invention adopts different threshold parameters, the scintillation of having avoided light compensating lamp to occur when opening and closing light compensating lamp.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is workflow diagram of the present invention.
Embodiment
See Fig. 1, Fig. 2, a kind of light compensating lamp autocontrol method based on video analysis specifically comprises the following steps:
