Problems solved by technology

[0004] The above scheme uses the accelerometer to determine the displacement, and the gyroscope to determine the attitude. The role of each sensor in generating the trajectory of space activity is relatively simple. Since the person is walking, the equipment equipped with the orientation sensor is also in a shaking state, and the above scheme is used to measure out The error of the space activity trajectory is relatively large, and the feasibility is not high

Abstract

The invention discloses a space-activity-track generating method and device. The space-activity-track generating method includes the steps that it is determined that a local machine is in the off-line state in which geographical location information can not be obtained; movement sensing data which is generated by an aspect sensor and used for representing spatial position variation of the local machine is obtained; according to the movement sensing data of one or more aspect sensors, one or more primary tracks are generated; after the local machine is recovered to be in the outer net accessing state, the multiple primary tracks are uploaded to a cloud-terminal server so that the multiple primary tracks can be fitted to spatial movement tracks when the local machine is in the off-line state. In addition, the invention further provides an intelligent device for carrying out the generating method. According to the method, the intelligent device is in the off-line state, the spatial movement tracks are generated according to the movement sensing data of the self-assembled aspect sensor of the intelligent device, the tracks generated with the method are accurate, reliable and suitable for various environments.

Description

technical field [0001] The present invention relates to the technical field of navigation, and more specifically, to a method and device for generating a trajectory of space activity. Background technique [0002] Navigation has become an indispensable part of our daily life. Whether driving or walking, navigation provides us with timely and effective services. Navigation is a method of guiding a certain device from one point of a specified route to another point, which requires a clear and complete map or path between the two points. The most advanced navigation technology is the Global Positioning System (GPS), which has been widely used in vehicle anti-theft, personnel positioning and other fields. It first locates the target, and then navigates according to the map that has been drawn. The navigation route is a necessary condition for navigation, and it cannot be navigated for some spatial scenes that lack the support of the navigation route. [0003] Generally, the ge...
