Method and device for generating space activity track

Abstract

The invention discloses a method and device for generating a space activity track. The method comprises the following steps: confirming an offline state of the machine when the geographical location information cannot be acquired; acquiring motion sensing data which is generated by a position sensor and is used for representing the change of the space position of the machine; and respectively generating one or more preliminary tracks according to the motion sensing data of one or more position sensors, and fitting the preliminary tracks into the space activity track when the machine is under the offline state. Besides, the invention further provides intelligent equipment for executing the method. The invention provides the method for generating the space activity track by the intelligent equipment under the offline state according to the motion sensing data of the position sensor arranged on the intelligent equipment. The generated track is accurate and reliable and is suitable for various environments. The space activity track generated according to the method can be used for offline navigation, offline addressing, spatial arrangement construction, and the like, so as to promote the user experience.

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...

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
