Description
[technical field]
The present invention relates to the monitoring camera field, especially relate to a kind of thermal camera.
[background technology]
Along with accident in the social security is increasing, people are also more and more higher to the requirement of shelter of public safety.Simultaneously, municipal public safety has become the important symbol of weighing urban modernization.The urban public security supervisory control system is exactly in the public place of main crossroads, commerce and trade community keypoint part and public security complexity surveillance equipment to be installed as one of security system of municipal public safety.These surveillance equipments be so that security administration department can obtain the visual information of guarded region and real-time current intelligence in the very first time, search site, recording image after also can the realization accident occuring, and the suspect follows the tracks of etc.The more important thing is that it has played powerful deterrent effect to the crime one's share of expenses for a joint undertaking, guarding side's safety as one " watcher ".
Night vision monitoring of the prior art all is to adopt infrared camera technology at present.Infrared photography is divided into passive type infrared photography and active infra-red shooting.The passive infrared shooting is to utilize any object that the principle of infrared light emission is arranged more than absolute zero (one 273 ℃).Passive infrared is not launched infrared ray, relies on the infrared radiation of target self to form heat picture, so be called again thermal imager.The principle of active infra-red shooting is to utilize a light projector device to send infrared light to the monitored area, and receive the infrared light that the monitored area reflects by camera head, through opto-electronic conversion and circuit amplification ratio after, produce corresponding signal, and then be transferred to control circuit or CPU and process displays image information on final monitoring screen.Most night vision product all is the active infra-red camera technique on the market at present.
The illuminating source of present infrared photography on the market generally all adopts LED.LED makes it become preferably infrared light supply with low power consuming, long-life characteristics.But because LED design and the selection of material is undesirable, the LED product has the shortcoming bad and too short life (too fast light decay) of dispelling the heat.For remote infrared monitoring, what generally adopt at present is single the infrared LED binding array that encapsulates through simple optically focused, forms high-power LED array to long distance light with the large tracts of land binding.But owing to its volume large and as the reasons such as aforementioned life-span weak point, illuminator maintenance cost height, restricting its further development and application.
In the prior art, all night vision infrared lamps all use the light source of fixed angle, generally are between 15 °～30 °.But when the night vision infrared lamp cooperates infrared integrated camera to use, a long way off the longest Jiao's camera lens visual angle often about 4 °.If to be equipped with 15 ° of angle night vision infrared lamps commonly used as example, because this is looked the infrared lamp angle and fixes, almost 93.1% infrared light be can't see do not use fully all beyond the invisible.If when use the infrared lamp of wide-angle more for looking after the monitoring of extensive angle closely, the infrared light of then wasting is more.On the other hand, use the night vision infrared lamp light source of fixed angle, when the camera lens of infrared integrated camera changes to wide-angle and greater than infrared when sending optic angle to spend, can occur again on the monitor screen " flashlight effect ", be bright in the middle of occurring on the monitor screen, four jiaos dark, in picture central overexposure appears and whiting affects picture quality.Especially, be applied to the special dimensions such as public security investigation when this infrared integrated camera, it is more flexible to need infrared integrated camera to use, and picture is more clear.
Comprehensive, because the light projection system of existing video camera all is fixing light projector angle and immutable, when causing camera angle to change, light projector can't unanimously cooperate, cause shooting at close range light not catch up with, the flashlight effect appears again in wide-long shot, the scene that can not clear effective shooting need to monitor.Especially, be applied to the special dimensions such as public security investigation when this infrared integrated camera, it is more flexible to need infrared integrated camera to use, and picture is more clear.
Therefore, develop a kind of new Focusable thermal camera, overcome many defectives of present prior art, become industry problem in the urgent need to address.
