Research And Design Of Interactive Game Platform Based On Somatosensory Technology

With the development of science and technology change rapidly, to improve the user requirements of the operation in the game, more and more people has been focused on the interactive game based on somatosensory technology. Compared with the traditional network game, it does not need to rely on the mouse and keyboard and other computer peripherals to operate in the plane, it can through the userhandheld somatosensory equipment to perceive the game. This paper focuses on the research in the somatosensory equipment system, positioning based on somatosensory technology, whether could achieve precise positioning, directly affects the user experience.This paper focuses on the research of gyroscope and camera localization algorithm. At the same time, according to the research, put forward the improved localization algorithm, and explains the reasons for the improvement of the gyroscope and camera positioning algorithm. The innovation of this paper is to achieve multiplayer interactive games, so the network platform is another important part of this paper.Through detailed research on somatosensory technology, and realized the design of human-computer interaction system, the gyroscope and camera positioning technology mainly explores the following aspects:The advantage of acceleration sensor and the gyro combination as the displacement signal acquisition system, introduced and analyzed these two kinds of sensors, focused on data fusion technology based on Calman filter, finally, realized the sensor data fusion algorithm based on Calman filter in the somatosensory device, processed the two sensor data and then fusion for somatosensory equipment track.Correcting the gyroscope and accelerometer data. The noise from the inside and outside the somatosensory equipment system, studied on the arithmetic mean filtering algorithm and made analysis and multi order simulation, the simulation results show that the filtering algorithm has a good smoothing effect on bare data. In view of the drift phenomenon of the acceleration sensor and the gyro, in the analysis of the zero drift of reference point after collection, put forward the zero offset value of zero drift self calibration dynamic reference point algorithm according to the operation state.Analyzing the image obtained from camera using different image processing technology, on the basis, selected the image processing method for the system. The appropriate image processing method:image enhancement technology and algorithm of the two value image processing, image edge detection and image feature extraction.Calibrated camera, established camera model, calculate the camera internal parameters and external parameters, with the internal and external camera parameters, calculated the somatosensory equipment angle and coordinate in the world coordinate system and to calculate the coordinates of somatosensory equipment on the3D screen.
