The invention discloses an indoor positioning method and device, electronic equipment and a storage medium, and relates to the field of artificial intelligence such as computer vision, image recognition, augmented reality and deep learning. The method can comprise the steps: obtaining at least two frames of images collected by a to-be-positioned user through an intelligent terminal, wherein the acquired images at least comprise two different interest points respectively located in different images, and respectively acquiring attitude information of the intelligent terminal during each image acquisition; respectively carrying out image identification on each collected image, and respectively obtaining the position information of each identified interest point; determining the positioning position of the user according to the position information of each interest point and the posture information corresponding to the image where each interest point is located. By applying the scheme of the invention, the implementation cost can be reduced, and the accuracy of the positioning result can be improved.
Description
technical field [0001] The present disclosure relates to the field of artificial intelligence technology, and in particular to indoor positioning methods, devices, electronic equipment and storage media in the fields of computer vision, image recognition, augmented reality and deep learning. Background technique [0002] At present, commonly used indoor positioning methods mainly include: 1) Indoor positioning based on hardware signal sources, laying signal sources in the area to be positioned in advance, and using the user's smart terminal to receive signals emitted by the signal source to achieve user positioning; 2) Based on visual features The matching indoor positioning method scans the area to be positioned in advance, collects visual image data and establishes a high-precision visual map, and realizes user positioning through feature matching and other methods; 3) The indoor positioning method based on image recognition recognizes the collected images ( The high-level...
