Embodiment Construction

[0183] 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...

Abstract

The invention provides a method for obtaining self-movement locus of an object. The method comprises the following steps: setting at least one fixed object as a position reference point, wherein a start point of the movement of the object is provided with one position reference point; transferring position information of the position reference point into the object and then taking the position information as a current movement reference point of the object; using a direction sensor and an acceleration sensor which are mounted on the object to measure a direction value and an acceleration valueduring the movement of the object; computing the movement locus of the object by using the direction value and the acceleration value which exist during the movement of the object together with the current movement reference point of the object, and storing the movement locus of the object into a storage component of the object; when the object passes the position reference point, transmitting the position information of the position reference point into the object for purpose of correcting the movement locus of the object, and obtaining the corrected movement locus of the object. The methodcan realize and obtain the position, the direction and the movement locus of the moving object at any time and solve the problem of way and direction loss.

Description

technical field [0001] The invention relates to a method for obtaining the object's own motion trajectory, in particular to a method for calculating the motion trajectory by using an acceleration sensor and an orientation sensor, and using a plurality of position reference points to correct the motion trajectory to obtain the object's own motion trajectory. 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 appearance of the compass has improved the accuracy of the azimuth information, but it is still impossible to know the informat...
