基于视频检测的教室人数统计系统的研发

Research and Development of Classroom Number Statistics System based on Video Detection

教室人数统计方法,该方法适用于在教室这个特定场景下使用,将采集视频的摄像头垂直向下拍摄,能够有效地避免人体相互遮挡和重叠,能够将人体目标划分为单独的个体。实验数据表明,该方法计算精度可达90%左右,计算速度可达每秒20帧左右。与现有方法相比,该方法在精度、实时性和健壮性方面都有很大的提高。

Statistical Method of Classroom Number.The method is suitable for the classroom which is the particular scenario.When the video is shooting , use the camera downward vertically, it can effectively avoid human bodies are shaded and overlapped each other. It can divide human targets into individual objects. The experimental data show that the computational accuracy of this method is about 90%, and the computing speed can reach about 20 frames per second. Compared with the existing methods, it has a great improvement in accuracy, real-time and robustness.
