Embodiment Construction
[0197] The core point of the present invention is to use a built-in acceleration sensor and an orientation sensor for a sports or mobile device, and obtain the trajectory or path of the motion or mobile device by processing the acceleration sensing signal and the orientation sensing signal through an information processor. Due to the accumulative effect of the error caused by the measurement error of the acceleration sensor and the orientation sensor and the calculation error of the information processor, the calculated motion trajectory or path deviation is too large. The position information of the reference position is added as the reference information of the calculated motion trajectory or path. Correction of calculation results. In order to achieve this goal, it is necessary to add a reference device at the reference position, and transmit the position information of the reference position to the motion or mobile device to participate in the calculation of the motion trac...

The invention discloses an electronic device for obtaining the three-dimensional motion trail of an object based on network computation. An electronic device is embedded into an object and comprises an orientation sensing component, an acceleration sensing component, an altitude sensing component, a communication component, a network communication interface, a storage component, an information processing component, wherein the communication component includes a near field wireless communication module and / or a wire communication module and communicates with a position reference device installed at a position reference point in a near field wireless communication mode or a wire communication mode so as to obtain the position information of the position reference point; and the information processing component transmits a triaxial orientation sensor signal, an altitude sensor signal and the position information of the position reference point combined with a triaxial acceleration sensorto a remote device and then computes the three-dimensional motion trail of the electronic device with respect to the position reference point. The electronic device can obtain the position, the orientation and the three-dimensional motion trail of the moving object at any time and solves the problems of losing way and direction.
Description
technical field [0001] The present invention relates to an electronic device for obtaining a three-dimensional motion trajectory of an object based on network calculation, in particular to an electronic device that uses an acceleration sensor, an orientation sensor, and an altitude sensor to measure and combine the network to calculate a three-dimensional motion trajectory, and uses multiple position reference points to correct the three-dimensional motion trajectory. equipment. Background technique [0002] From ancient times to the present, people have been exploring how to locate their own location and orientation, so as not to lose their way and fail to reach their destination. The appearance of the early compass provided a convenient solution for people to determine the orientation, but because of its function of providing general orientation information, the accuracy of the orientation was not high, and it was impossible to know the information of the location. The ap...
