热图生成方法
摘要：
本发明涉及一种热图生成方法，包括：视频图像获得步骤，获得需进行识别的监控区域的视频图像；遮挡区确定步骤，根据所述视频图像，确定所述监控区域中的需识别遮挡区；遮挡区人数确定步骤，利用WiFi技术获得所述需识别遮挡区中的人数；非遮挡区确定步骤，确定所述监控区域中需识别的非遮挡区；非遮挡区人数确定步骤，利用视频识别技术识别所述非遮挡区的人数；人口密度确定步骤，利用所述遮挡区人数确定步骤所识别出的人数和所述非遮挡区人数确定步骤所识别出的人数，确定所述监控区域的人口密度。
摘要（英）：

The invention relates to a thermal map generating method comprising: a video image obtaining step of obtaining a video image of a monitoring area to be recognized; an occlusion area determining step of determining an occlusion area needing recognition in the monitoring area based on the video image; a step of determining the number of people in the occlusion area which utilizes wifi technology to obtain the number of people in the occlusion area needing recognition; a non-occlusion area determining step of determining a non-occlusion area needing recognition in the monitoring area; a step of determining the number of people in the non-occlusion area which utilizes video recognition technology to obtain the number of people in the non-occlusion area; and a population density determining step which uses the number of people recognized by the step of determining the number of people in the occlusion area and the number of people recognized by the step of determining the number of people in the non-occlusion area to determine the population density of the monitoring area.
