Problems solved by technology

However, this IMU sensor can only obtain the angle information of the terminal device on the three axes when it rotates and moves, but cannot obtain the position information of the terminal device on the three axes. If the position of the terminal device on the three axes is obtained in advance information, it is also necessary to perform attitude estimation by setting up a camera outside the terminal device. This method has a very large amount of calculation, and the use of an external camera and the use of computing equipment lead to very high costs.

Abstract

The invention discloses a motion information detection system and method. The motion information detection system includes an information processing device and at least two information detection devices, each information detection device includes a three-axis attitude measurement sensor, and the at least two information detection devices are arranged on different objects to be measured in series, so The information detection device is used to transmit the sensing data detected by the three-axis attitude measurement sensor to the information processing device, and the information processing device is used to transmit the data transmitted by the at least two information detection devices respectively The sensing data and the endpoint distance between the two serial connection endpoints of each object to be measured are used to determine the six-degree-of-freedom motion information of the serial connection endpoints of each object to be measured, thereby obtaining rich motion information of the object to be measured.

Description

technical field [0001] The present invention relates to the field of information technology, and in particular, to a motion information detection system and a motion information detection method. Background technique [0002] During the use of a terminal device such as a handheld device, in order to obtain the motion information of the terminal device, a sensor is usually installed in the terminal device, and the motion information of the terminal device is obtained by analyzing and calculating the sensing data detected by the sensor. [0003] In the existing terminal equipment, the motion information of the terminal is mainly obtained by installing a three-axis attitude measurement sensor, such as installing an IMU sensor in the terminal equipment. However, this IMU sensor can only obtain the angle information of the terminal device in the three axes when it rotates and moves, but cannot obtain the position information of the terminal device in the three axes. information,...
