Novel indoor positioning method for smart home robot

The invention relates to the technical field of smart home and industrial intelligent control, in particular to a novel indoor positioning method for a smart home robot. The method comprises the following steps that a camera with an infrared module is arranged at the top of an intelligent home robot, all indoor rooms are traversed under manual command, and images of the tops of all the rooms are collected and spliced into a whole roof image; placing the whole roof image in the same world coordinate system; the whole roof image is processed, corresponding feature information is extracted, and the feature information represents the area, sufficient to position, of each room ceiling; scanning an image of the top of the room at the current position by using a camera with an infrared module; and the feature information is compared, so that the current coordinate information of the smart home robot is determined according to the ceiling feature information, and the requirements of certain positioning, calculation a
