The invention relates to an elevator door detection method based on TOF light field equipment. The method comprises the following steps that a detection instruction transmitted by an elevator controlsystem is received, a depth information graph comprising a light field in an elevator door frame range is obtained, the depth information graph is depth data of TOF light field equipment, and the depth data are processed by a light field in an elevator door frame range, and collected by a TOF depth data sensor; a sampling range graph corresponding to the elevator door frame range is intercepted from the depth information graph according to pre-acquired original detection range graph information; the sampling range graph is analyzed according to pre-acquired original detection range graph information, and whether an obstacle warning signal or a fault warning signal needs to be sent to an elevator control system or not is judged; the original detection range graph information is grey-scale graph information corresponding to the elevator door frame obtained in a range calibration mode. According to the method, the defect that a blind area exists when the elevator door frame is detected through an infrared light curtain technology in the prior art is overcome.
本发明涉及一种基于TOF光场设备的电梯门检测方法,方法包括:接收到电梯控制系统发出的检测指令,获取包括电梯门框范围内光场的深度信息图,深度信息图为TOF光场设备对TOF深度数据传感器采集的经由电梯门框范围的光场处理后的深度数据;根据预先获取的原始检测范围图信息,从深度信息图中截取与电梯门框范围对应的采样范围图;根据预先获取的原始检测范围图信息,对采样范围图进行分析,判断是否需要向电梯控制系统发送障碍物告警信号或故障告警信号;原始检测范围图信息为在范围标定模式下获取的电梯门框对应的灰度图信息。上述方法解决了现有技术中红外光幕技术检测电梯门框时存在盲区的缺陷。
