description The invention provides an indoor positioning system. The system comprises a processor, at least one image acquisition device and at least one movable device, the image acquisition device is fixedly installed on the indoor ground or an indoor wall, the processor is in communication connection with the image acquisition device, and the indoor positioning system further comprises a calibration mechanism. The calibration mechanism is fixedly installed on at least one movable device, the calibration mechanism comprises a plurality of calibration points, the calibration points are parallel to one another and are separated from one another by a certain calibration distance, and the image acquisition device is used for acquiring at least two indoor images and feeding back the indoor images to the processor. And the processor is used for obtaining the final displacement of the movable device according to the indoor image and the calibration distance, and positioning the movable device according to the final displaceme
