Elevator protection method based on TOF camera

The invention discloses an elevator protection method based on a TOF camera. The TOF camera is mounted over an elevator door, through images collected by the TOF camera, different algorithms are adopted in a landing door and car door, the position close to an elevator car door and the elevator car door, whether an obstacle exists nearby the elevator door is judged, according to the judging result,corresponding action is carried out, safety run control over an elevator is achieved, accidents are prevented, and safety of a person or animals is ensured. 本申请公开了一种基于TOF相机的电梯保护方法，TOF相机安装在电梯门的正上方，通过设TOF相机采集的图像，分别对厅门与轿门处、靠近电梯轿门、电梯轿门处采用不同的算法，对电梯门附近是否存在障碍物进行判断，根据判断结果进行相应动作，实现对电梯的安全运行控制，防止事故的发生，保护人或动物的安全。
