警察作为高危险性的职业一方面是由于执法环境导致的,另一方面是因为存在着太多的不确定性,警用装备的现代化建设是当前公安、刑警工作的重要组成部分。采购适用的配装、技术先进的警用装备是现代化建设的重要环节,在日常工作当中起到了极其重要的作用。

据统计,犯罪分子在夜间实时犯罪的概率最大。因为夜间存在极大的可隐蔽性和迷惑性,方便实时犯罪。那么,有哪些专业设备可以配合警察在夜间抓捕罪犯或者警备巡逻呢?

晚上能用到的专业设备有两大类:1、红外热成像仪;2、夜视仪。这两大类设备各有利弊。

1、红外热成像仪

红外热成像仪最核心的部件是红外探测器,红外探测器会感知来自目标表面的红外热辐射,通过热成像仪的镜头,反应到红外探测器的成像平面上,根据物体表面温度不同,呈现不同的图像。红外热成像仪最主要的特点是不主动发生红外,而是被动接受来自目标的红外热辐射,优点非常明显了,具有极强的隐蔽性,不容易被目标发现,这在执行任务时显得尤为关键,有可能直接决定任务成败。红外热成像仪在发现目标方面优势明显。

2、夜视仪

夜视仪是一种夜晚观测目标的隐蔽设备。夜视仪的原理是将来自目标的人眼看不到的光(微光或者红外光)信号转换为电信号,然后再把电信号放大,并把电信号转换为人眼可见的光信号。专业讲:夜视仪原理就是通过目镜将光线聚焦在影象增强器上来采集和增强现有光线,在增强器内部,一个光电阴极会被光“激活”,并将光子能量转变成电子,这些电子经过一个位于增强器内部的静电区域被加速后,撞击在磷表面屏幕上(就好象一个绿色的电视屏幕),形成人眼可见的图象。经过对电子的加速,增强了亮度和图象的清晰度。

夜视仪最主要的优点是容易识别目标,防止误伤或者抓错犯罪分子。夜视仪上面一般都有一个红外灯,作为辅助光源。在微光情况可以关闭红外灯,更具有隐蔽性。但是在全黑或者光线很暗的情况下,就必须开启红外灯。这也存在着一个弊端,容易被被观测目标发现,有可能导致任务的失败。

红外热成像智能夜视视频监控技术 https://www.hjkir.com/industry/en/1569.html Thu, 08 Apr 2021 06:22:03 +0000 https://www.hjkir.com/?p=1569 Infrared thermal imaging technology is a passive infrared night vision technology. Its principle is based on the fact that all objects whose temperature is higher than absolute zero in nature radiate infrared rays all the time. At the same time, this infrared radiation carries the characteristic information of the object, which provides an objective basis for using infrared technology to distinguish the temperature and heat distribution field of various measured targets. Using this feature, after the power signal radiated by the heating part of the object is converted into an electrical signal through the photoelectric infrared detector, the imaging device can simulate the spatial distribution of the temperature on the surface of the object one by one. Finally, after being processed by the system, a thermal image video signal is formed and transmitted to the display screen to obtain the thermal image corresponding to the thermal distribution on the surface of the object, that is, the infrared thermal image.

Intelligent night vision video surveillance technology is the application of computer vision and pattern recognition technology in the field of video surveillance. It can automatically detect, recognize, track and analyze the targets in video images, so as to provide users with key information useful for monitoring and early warning.

The on-board night vision system based on infrared thermal imaging is an active safety device for vehicles, which uses infrared thermal imaging technology to assist drivers to see the road ahead at night and in the case of low visibility, identify pedestrians in front of the vehicle, assist drivers to predict the road ahead and the location of pedestrians, prevent hazards in advance, and reduce traffic accidents.

Using the infrared thermal imager and its supporting software and infrared thermal imaging algorithm technology, we can realize 24-hour uninterrupted and barrier free monitoring of border areas, border and coastal defense posts, unattended border defense stations, unmanned pirates, entry and exit ports, etc. by using the function of dynamic monitoring and detection system, we can make up for the shortcomings of satellite remote sensing and ground mobile monitoring, and provide all-weather, all-weather Uninterrupted information on the actual situation and dynamic changes of border management, so as to realize the scientization, systematization, real-time and visualization of border management. The system can also be used normally under various climatic conditions and no light at night, realizing 24-hour real-time recording of sea / ocean conditions, timely discovering the status of the shipbuilding industry, island and island ecological environment monitoring, illegal sand mining, illegal reclamation / use of the sea, random sewage discharge at the entrance to the sea, illegal development of islands, cross-border fishing by fishermen of other countries, and other phenomena, so as to facilitate the smooth channel, effective management of sea / Island Provide good intelligent assistance in maritime border defense management.
