    • A method and device for safeguarding a hazardous working area includes a camera system for generating successive 3-D images of the working area, and an evaluation unit comprising a fail-safe foreign object detector, a classifier, a person tracker and a comparator. The foreign object detector generates a first signal comprising a first item of position information, representative of the position of a foreign object in the protection zone. The classifier attempts to identify the foreign object as a person. The person tracker tracks an identified person using a series of current 3-D images and, after each new 3-D image, determines a second item of position information representing the current position of the identified person. If the position of the foreign object according to the first item of position information and the position of the identified person are different from one another, a control signal for stopping the machine is generated.
    • 用于保护危险工作区域的方法和装置包括用于产生工作区域的连续3-D图像的相机系统,以及包括故障安全异物检测器,分类器,人物跟踪器和比较器的评估单元。 异物检测器产生第一信号,该第一信号包括表示异物在保护区中的位置的第一项位置信息。 分类器试图将异物识别为一个人。 人物跟踪器使用一系列当前3-D图像跟踪识别的人物,并且在每个新的3-D图像之后,确定表示所识别的人的当前位置的位置信息的第二项。 如果根据位置信息的第一项目的异物的位置和所识别的人的位置彼此不同,则产生用于停止机器的控制信号。

    • A monitoring device configured to monitor whether a look of a target person is in a proper state suitable for a working environment, and comprising: an image input unit configured to input an image of the target person; a detector configured to analyze the image input by the image input unit and detect a predetermined region of a human body of the target person; a state estimator configured to estimate a state of the predetermined region detected by the detector; a proper state acquisition unit configured to acquire proper state information on a proper state of the predetermined region according to the working environment; and a controller configured to determine whether a present state of the predetermined region of the target person is proper by comparing an estimation result of the state estimator to the proper state information, and perform control according to a determination result.
    • 一种监视装置,被配置为监视目标人物的外观是否处于适合于工作环境的适当状态,并且包括:图像输入单元,被配置为输入目标人物的图像; 检测器,被配置为分析由图像输入单元输入的图像并检测目标人的人体的预定区域; 状态估计器,被配置为估计由所述检测器检测到的所述预定区域的状态; 适当状态获取单元,被配置为根据工作环境获取关于预定区域的适当状态的适当状态信息; 以及控制器,被配置为通过将状态估计器的估计结果与适当状态信息进行比较来确定目标人物的预定区域的当前状态是否正确,并且根据确定结果执行控制。
