The invention relates to an intelligent light supply system for an infrared dome camera. The intelligent light supply system comprises a hardware part and a software part; the hardware part comprises a main control chip, a CCD camera, a light source driving chip, an infrared lamp panel and a control keyboard; the main control chip is separatelyconnected with the CCD camera and a light-sensitive resistor; the main control chip and the CCD camera perform signal feedback; the CCD camera is controlled by the control keyboard; the light source driving chip is connected with the infrared lamp panel; and the software part comprises a real-time multiple system of a CCD lens and a matching algorithm of the brightness of an infrared lamp and the multiplying power of a lens. According to the invention, on the basis of the matched design of the brightness of the infrared lamp and the multiplying power of the lens, current flowing through the infrared lamp is changed according to the current magnification when an image is acquired; the brightness of the infrared lamp is adjusted; therefore, energy consumption is effectively reduced; and the overexposure phenomenon of the centre of an image subjected to short-distance acquisition because the infrared lamp is too bright under the low multiple can be greatly improved.
Description
Technical field
The invention belongs to traffic intelligent administrative skill field, relate in particular to a kind of infrared ball machine Intelligent supplemental lighting system.
Background technology
What CCTV camera imaging relied on is optical imaging sensor, mainly respond to extraneous light and be converted into the signal of telecommunication, more even do not have in light situation at light, all generally by widening time for exposure gain amplifier value object, but image noise is at this time very large, can not meet the requirement of safety monitoring, so giving environment light-supplementing that video camera shines is exactly the most direct method, light filling is generally with infrared light, because infrared light human eye is difficult for catching, but the optical imaging sensor of video camera can be responded to infrared light, be equivalent to strengthen extraneous light by people for adding infrared light, so even can reach in the completely unglazed situation of external environment and monitor, but at present in actual applications, the light-supplementing system of infrared spherical camera still exists following two problems: light compensating lamp is generally in series by multiple infrared lamps, and the infrared lamp light intensity of common infrared spherical camera designs by maximum distance, once infrared lamp is opened, its operating current will be larger, power consumption is naturally just large, heating is serious, work long hours and can cause the infrared lamp life-span to decline, and the life-span of infrared lamp has directly determined the life-span of infrared spherical camera, can be because infrared lamp brightness be excessively strong in the time of monitoring closer object, lighting angle is too concentrated and generation picture centre overexposure phenomenon.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of infrared ball machine Intelligent supplemental lighting system, solves infrared lamp luminous intensity consistent all the time, and brightness causes excessively by force the problem of the picture centre overexposure of taking.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
Infrared ball machine Intelligent supplemental lighting system, comprise hardware components and software section, described hardware components comprises main control chip, power supply, crystal oscillator, ccd video camera, light source drive chip, photo resistance, infrared light board and supervisory keyboard, described main control chip respectively with power supply, crystal oscillator, ccd video camera is connected with photo resistance, main control chip and ccd video camera carry out mutual signal feedback, described ccd video camera is controlled by supervisory keyboard, described photo resistance is controlled by main control chip, photo resistance is connected with light source drive chip, described smooth source drive chip is connected with infrared light board, described software section comprises real-time times of number system of CCD camera lens and infrared lamp brightness and lens ratio matching algorithm.
Described ccd video camera camera lens is arranged on infrared light board center.
Beneficial effect of the present invention: based on the design that matches of infrared lamp brightness and camera lens multiplication factor, gathering when image according to current multiplication factor, thereby change the size of current that flows through infrared lamp by main control chip control, with the light-supplementing system of common infrared spherical camera under any multiple infrared lamp output be all compared with high-high brightness, the design has reduced the brightness of infrared lamp under identical multiple, effectively save energy consumption, particularly reduce the heating of infrared light board, and greatly improve because the bright closely collection picture centre overexposure phenomenon problem causing is crossed in infrared lamp brightness under low multiple.
Brief description of the drawings
Fig. 1 is the structured flowchart of the embodiment of the present invention.
Detailed description of the invention
For making object of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing, embodiments of the present invention are at length set forth.
With reference to figure 1, infrared ball machine Intelligent supplemental lighting system, comprise hardware components 1 and software section 2, described hardware components 1 comprises main control chip 15, power supply 14, crystal oscillator 13, ccd video camera 12, light source drive chip 17, photo resistance 16, infrared light board 18 and supervisory keyboard 11, described main control chip 15 respectively with power supply 14, crystal oscillator 13, ccd video camera 12 is connected with photo resistance 16, main control chip 15 carries out mutual signal feedback with ccd video camera 12, described ccd video camera 12 is controlled by supervisory keyboard 11, described photo resistance 16 is controlled by main control chip 15, photo resistance 16 is connected with light source drive chip 17, described smooth source drive chip 17 is connected with infrared light board 18, described software section 2 comprises real-time times of number system 21 of CCD camera lens and infrared lamp brightness and lens ratio matching algorithm 22.
Described ccd video camera 12 camera lenses are arranged on infrared light board 18 centers.
Power supply 14, crystal oscillator 13 and main control chip 15 in described hardware components 1 form little SCM system, in main control chip 15, embed timer, the timer embedding produces digit pulse receiving after the signal of camera lens, change the register value on timer by programming, thereby produce different digital pulse signals; Photo resistance 16 passes to light source control chip 17 after receiving signal, and light source control chip 17 carries out light modulation to the LED lamp on infrared light board 18 after receiving the signal of photo resistance 16, realizes the lamplight brightness that infrared lamp and ccd video camera 12 lens ratio match.
Described software section 2 is realized light filling and is divided two steps to carry out, first ccd video camera 12 camera lenses are by communicating with main control chip 15 mainboards, when serial port of mainboard receives after the control command that camera lens is zoomed in or out, corresponding flag bit carries out set, by judging whether the multiplication factor that this flag bit just can real-time query camera lens changes, once and camera lens multiplication factor changes, system will be obtained camera lens multiplication factor immediately. Secondly, for realizing camera lens multiplication factor and infrared lamp brightness matches, system call respective algorithms, application of formula is mapped brightness and camera lens multiplication factor, sends signal and realize by hardware components 1 adjusting of infrared lamp brightness.
Above one embodiment of the present of invention are had been described in detail, but described content is only preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention. All equalization variation and improvement etc. of doing according to the present patent application scope, within all should still belonging to patent covering scope of the present invention.
