| description | The invention discloses a depth camera safety control method and device and a ToF depth camera. The depth camera safety control method comprises the following steps: S10, acquiring a RAW image acquired by an image sensor; s20, selecting pixel points in a certain area in the RAW image, and calculating a pixel overexposure proportion and average light intensity; and S30, performing safety judgment according to the pixel overexposure proportion and the average light intensity, and adjusting the integral time of the pixel. Safety judgment is carried out according to the pixel overexposure proportion and the average light intensity, the integral time of the pixels is adjusted, the exposure time under the short-distance condition is shortened, and therefore human eye laser safety protection is achieved.
本发明公开了一种深度相机安全控制方法、装置、及ToF深度相机，包括：S10、获取图像传感器所采集的RAW图像；S20、选取所述RAW图像中一定区域内的像素点，计算像素过曝比例以及平均光强度；S30、根据所述像素过曝比例以及平均光强度进行安全判断，调节像素的积分时间。本发明根据像素过曝比例以及平均光强度进行安全判断，调节像素的积分时间，降低近距离情况下的曝光时间，从而实现人眼激光安全保护。 |
