Abstract

The invention discloses an intelligent location tracking manipulation pen and a processing method of spatial interaction sensor original data. The manipulation pen comprises a pen-like shell and an intelligent control circuit board, the intelligent control circuit board is arranged in a containing cavity of the pen-like shell, and the intelligent control circuit board comprises a motion sensor, a processing unit, a communication unit, a feedback prompting unit and a space coordinate signal unit. The method comprises the steps that firstly, the motion sensor detects parameters of a manipulation pen sensor; secondly, the processing unit reads the original data of the manipulation pen sensor, and whether the original data of the sensor is valid or not is judged; thirdly, the processing unit conducts average filtering on the original data of the sensor, and the euler angle parameter and the quaternion of the manipulation pen are obtained; fourthly, the euler angle parameter and the quaternion of the manipulation pen are transmitted to a special interactive device through the communication unit, and a spacial sensor of the manipulation pen is determined. The drift phenomenon is solved, a nine-axis motion sensor and the infrared track technology are utilized, so that the precision for tracking the spacial sensor of the manipulation pen is greatly improved, and the user experience is improved.

Description

technical field [0001] The invention relates to the field of 3D stereo technology, in particular to an intelligent position tracking control pen and a processing method for raw gesture data. Background technique [0002] The existing interactive control pen has a built-in motion sensor and an infrared transmitter, and is used in conjunction with a 3D display device through an HDMI cable. The HDMI cable transmits the spatial data of the control pen to the 3D display device for processing, and the 3D display device is tracked and controlled through an infrared tracking module. The infrared transmitter of the pen determines the approximate position of the control pen, superimposes the spatial data transmitted by the HDMI cable to determine the precise position of the cursor, and operates the 3D content on the 3D display device. However, this control pen mainly has the following problems : [0003] 1. Through the HDMI cable, the space and motion data detected by the motion sens...

Problems solved by technology

[0005] Aiming at the problem that when the existing control pen is used in conjunction with the 3D display device, the 3D display device freezes, the 3D display device crashes, and the cursor appears to "drift", resulting in poor user experience, an intelligent position tracking control pen and gesture is proposed. The processing method of the original data, the processing unit is set in the intelligent control circuit board of the control pen, and the acceleration parameters, angular velocity parameters and direction parameters of the three degrees of freedom detected by the nine-axis sensor are fused to obtain the Euler angle parameters of the control pen And quaternions, transmitted to a specific interactive device to position the space sensor of the smart position tracking control pen, greatly reducing the processing burden of the interactive device, the direction sensor data detected by the geomagnetic sensor in the nine-axis sensor unit is very important to the existing smart position The space sensor data of the tracking control pen is effectively corrected, which improves the tracking accuracy of the space movement position of the intelligent position tracking control pen. In the present invention, the USB data line of the HID protocol is used to connect with the interactive device, which has strong versatility
