Abstract: A human monitoring system includes a plurality of cameras and a visual processor. The plurality of cameras are disposed about a workspace area, where each camera is configured to capture a video feed that includes a plurality of image frames, and the plurality of image frames are time-synchronized between the respective cameras. The visual processor is configured to receive the plurality of image frames from the plurality of vision-based imaging devices and detect the presence of a human from at least one of the plurality of image frames using pattern matching performed on an input image. The input image to the pattern matching is a sliding window portion of the image frame that is aligned with a rectified coordinate system such that a vertical axis in the workspace area is aligned with a vertical axis of the input image.
Abstract translation: 人类监控系统包括多个照相机和视觉处理器。 多个摄像机围绕工作区域设置，其中每个摄像机被配置为捕获包括多个图像帧的视频馈送，并且多个图像帧在各个相机之间是时间同步的。 视觉处理器被配置为从多个基于视觉的成像设备接收多个图像帧，并且使用在输入图像上执行的模式匹配从多个图像帧中的至少一个检测人的存在。 图案匹配的输入图像是与整流坐标系对准的图像帧的滑动窗口部分，使得工作区域中的垂直轴与输入图像的垂直轴对齐。
