Calibration method for TOF elevator safety light curtain alarm area

The invention provides a TOF elevator safety light curtain alarm area calibration method which comprises the steps that S1, a TOF light curtain sensor is triggered to be in a calibration mode, and the TOF light curtain sensor emits a fan-shaped TOF safety light curtain; s2, in a calibration mode, four mark points are placed in a fan-shaped range of the TOF safety light curtain, and the TOF safety light curtain automatically identifies and calculates an area defined by the four mark points; s3, whether an object exists in an area defined by the four mark points or not is judged; and S4, if the object exists, the TOF safety light curtain gives an alarm prompt. Based on the calibration method of the TOF safety light curtain, after the same TOF safety light curtain device leaves a factory, the client can set the detection area of the device by itself according to the size of the alarm area which is actually needed, so that the problem that different product models are set to meet the requirements of different cli
