通过直线判断图像的倾斜角度，并将其自动旋转正(Judging the tilt angle of an image by a straight line and automatically rotating it forward)

说明：  本设计是将安卓技术、单片机技术、无线通信技术等相关技术应用到视频监控系统中，可实现视频监控系统的设备移动化，由可移动监控平台、控制软件两部分组成。通过无线网络对监控平台进行移动方向、速度的控制，平台上的安卓手机摄像头实时采集视频图像信号并通过无线WiFi网络将视频信号实时传输到手机端观看。具有控制方便，监控灵活，模块化，可拓展性强等优点，可应用于险情探测、防爆、现场巡视、家庭安防、图像采集等领域。此部分是电脑端Java程序。(This design applies Android technology, microcontroller technology, wireless communication technology and other related technologies to the video surveillance system, which can realize the equipment mobility of the video surveillance system. It consists of mobile monitoring platform and control software. The mobile direction and speed of the monitoring platform are controlled by wireless network. The Android mobile camera on the platform collects video image signals in real time and transmits them to the mobile terminal for viewing through wireless WiFi network. It has the advantages of convenient control, flexible monitoring, modularization and expansibility. It can be used in danger detection, explosion-proof, on-site inspection, family security, image acquisition and other fields.)

计算平面面形的pv值和rms值，通常用在光学表面形貌测量中(Calculating the Pv value and RMS value of the plano surface)

说明：  基于多站纯方位粒子滤波目标跟踪系统，多个观测站，匀速直线运动目标(Target tracking system based on multi-station bearings-only particle filter)
