【摘要】：在现代信息社会中,便携式的手持观测终端的研究越来越受到重视。对这些便携式的手持设备所具有的功能要求也是越来越多,单一功能的设备已经无法满足用户的需求。手持终端的使用范围也越来越大,在平安城市建设、公安执法、海上监控等特殊领域都已经普及。本文设计的一种具备目标定位功能的昼夜观测系统,采用可见光成像的CCD摄像机和利用红外线成像的热成像探测器进行视频的输入。在白天光线充足的时候,将成像系统切换到CCD成像上,在夜晚或者光线不够好的情况下将成像系统切换到热成像上。其中,热成像是利用景物本身向外辐射出的红外线来进行成像的,具有良好的隐蔽性,适合军事侦察中使用。系统集成了 GPS/BD2定位功能,在我们国内可以通过北斗二代卫星进行定位,具有定位功能;系统集成了电子罗盘功能,可以获得观测者所处位置的方位信息;系统还集成有激光测距机功能,可以指向目标物,测出观测者和目标物之间的距离信息。整个系统通过三节18650锂电池进行供电,可以保障系统连续工作时间,还配有电量检测功能,实时监控系统的电量。系统内部通过核心的运算处理单元TMS320DM368对所测数据进行处理,可以计算出目标物所处位置的坐标信息。系统的电路部分可以对输入的视频进行一系列的解码和编码操作,实现摄录和拍照功能,方便用户进行下一步的取证分析工作。
[Abstract]:In modern information society, more and more attention has been paid to portable handheld observation terminals. These portable handheld devices have more and more functional requirements, single function devices can not meet the needs of users. The use of handheld terminals has become more and more widespread in the construction of peaceful cities, public security law enforcement, maritime surveillance and other special fields. A day and night observation system with the function of target location is designed in this paper. The CCD camera with visible light imaging and the thermal imaging detector with infrared imaging are used to input video. When there is enough light during the day, the imaging system is switched to CCD imaging, and the imaging system is switched to thermal imaging at night or when the light is not good enough. Among them, thermal imaging is based on infrared radiation from the scene itself, which has good concealment and is suitable for military reconnaissance. The system integrates GPS / BD2 positioning function, which can be located by Beidou second generation satellite in our country, the system integrates electronic compass function, and can obtain the position information of the observer. The system also integrates the function of laser rangefinder, which can point to the object and measure the distance information between the observer and the object. The whole system is powered by three sections of 18650 lithium battery, which can guarantee the continuous working time of the system, and also has the function of measuring the electric quantity and monitoring the power of the system in real time. In the system, the measured data can be processed by the core processing unit TMS320DM368, and the coordinate information of the position of the object can be calculated. The circuit part of the system can perform a series of decoding and coding operations on the input video, realize the functions of recording and photographing, and facilitate the next step of forensic analysis.
