Abstract

The invention discloses an indoor positioning method and system. The method comprises the steps of: obtaining a first ceiling shot image of an indoor practical ceiling by a camera, calculating a corresponding conversion matrix from the first ceiling shot image to the practical ceiling; controlling an indoor device to be positioned to emit light signals to the practical ceiling, and generating corresponding projection points on the practical ceiling; obtaining a second ceiling shot image including the projection points by the camera, and calculating the coordinates of the projection points on the second ceiling shot image; and according to the conversion matrix, converting the coordinates of the projection points on the second ceiling shot image into the corresponding practical coordinates on the practical ceiling, and positioning the device to be positioned according to the practical coordinates. In this way, the device to be positioned is positioned, the positioning method is simple, the positioning error is small, the practicability is high, and great convenience is provided to a user.

Description

technical field [0001] The present invention relates to the technical field of indoor positioning, in particular to an indoor positioning method and system. Background technique [0002] Indoor positioning refers to the realization of position positioning in the indoor environment. It mainly adopts wireless communication, base station positioning, inertial navigation positioning and other technologies to form an indoor position positioning system, so as to realize the position monitoring of people and objects in the indoor space. At present, indoor positioning technology mainly adopts sound wave or ultrasonic positioning, wireless radio frequency signal (such as router signal) positioning, etc. These positioning methods have problems such as poor anti-interference ability and large positioning error, and the algorithm is relatively complex, high cost, and not practical. . [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention...
