Problems solved by technology

GPS and other satellite positioning technologies have higher coordinate positioning accuracy in the plane direction, but lower positioning accuracy in the altitude direction
Therefore, in the face of complex three-dimensional traffic, even if travelers use the navigation and positioning function of electronic devices to choose travel routes, they may still choose the wrong road due to the inaccurate positioning in the direction of altitude.

Abstract

The embodiment of the invention provides an altitude measurement method and electronic equipment, and relates to the technical field of positioning and navigation. The method comprises the following steps: 1, when the electronic equipment is located at the first position, the altitude corresponding to the first position is obtained through a navigation positioning device and an electronic map, andwhen the electronic equipment moves from the first position to the second position, the altitude corresponding to the second position is obtained according to the altitude corresponding to the firstposition and the sensor data measured by the sensor. According to the scheme, the altitude measurement precision can be improved. In addition, the hardware cost of the electronic equipment does not need to be increased, and the universality and the practicability of the scheme are guaranteed.

Description

technical field [0001] The present application relates to the field of terminal technologies, and in particular to a method for measuring altitude and electronic equipment. Background technique [0002] With the three-dimensional development of urban traffic, traffic forms such as viaducts, overpasses, and tunnels are becoming more and more common. These three-dimensional traffic is of great significance to the development of urban traffic and the rapid passage of vehicles. However, the three-dimensional traffic brings difficulties to the traveler's road choice to a certain extent. Travelers often choose the wrong road when facing the intricate three-dimensional traffic. [0003] At present, users can use electronic devices with navigation and positioning functions to select travel routes. Currently, the navigation and positioning functions of electronic devices mainly rely on satellite positioning technologies such as the global positioning system (GPS). GPS and other s...
