Abstract

The embodiments of the present application propose a positioning method, apparatus, and terminal device based on fusion information. The method includes: acquiring first positioning information of the target user at a first moment, and acquiring a first environment image of the target user at the first moment; acquiring measurement positioning information of the target user at a second moment; acquiring at the second moment For the second environment image of the target user, according to the first environment image and the second environment image, determine the positioning increment of the target user from the first moment to the second moment; according to the first positioning information and the positioning increment, determine the positioning increment of the second moment. Predicted positioning information; based on the measured positioning information at the second moment, update the predicted positioning information at the second moment to obtain the second positioning information of the target user at the second moment, and output the second positioning information. The present application can be applied to scenarios such as vehicle positioning, conference room positioning, shopping mall positioning, etc., which enriches positioning methods and effectively improves positioning accuracy.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a positioning method, device and terminal equipment based on fusion information. Background technique [0002] With the advancement of science and the development of technology, the application scenarios of terminal devices such as smart phones are becoming more and more extensive. Among the many application scenarios of terminal devices, location-based services aim to provide accurate and convenient indoor positioning services, which can significantly improve our daily life. In many scenarios such as shopping malls, parking lots, large office buildings and hospital healthcare, the importance of indoor positioning and navigation technology is becoming more and more prominent. Indoor location-based services such as finding the specific location of the meeting room in the mobile phone and finding a parking space in the underground parking lot. [0003] At present, the...
