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 trajectory generation method and device. The generation method comprises the steps that the situation that a machine is in an off-line state of failing to obtain geographical location information is determined; motion sensing data which is generated by direction sensors and represents the space position changes is obtained; when the machine is returned to a state of having access to the outside network, the motion sensing data is uploaded to a cloud server so as to fit space activity trajectories of the machine in the off-line state according to the motion sensing data. The invention further provides an intelligent device used for executing the generation method. The invention provides the method for generating the space activity trajectories according to the motion sensing data of the multiple direction sensors in the off-line state. The generated space activity trajectories are accurate, reliable and suitable for various environments. The space activity trajectories generated according to the method can be used for offline navigation, offline addressing, spatial layout construction and the like, and therefore the user experience is improved.

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...
