摘要
针对传统的信息单点采集法易受峰值信噪比影响而导致成像精度低和成像中心偏移问题,设计了一种虚拟现实仿真中图像合成过程的信息多点采集方法。利用摄像机的成像原理建立了摄像机坐标系,通过坐标系转化公式确定了摄像机的内外参数,进行了摄像机的标定。利用立体视觉原理,从不同角度获取了物体或场景图像的相关信息,完成了图像合成过程的信息多点采集。通过实验得出以下结论:合成后图像中心与实际中心位置相符,信息采集的精度较高。
Traditional single point information acquisition method is easily affected by the peak signal-to-noise ratio, which leads to low imaging accuracy and imaging center offset, a multi-point information acquisition method for image synthesis process in virtual reality simulation is designed. The camera coordinate system is established by using the imaging principle of the camera. The internal and external parameters of the camera are determined by the transformation formula of the coordinate system, and the camera calibration is carried out.Based on the principle of stereo vision, the information of objects or scenes is obtained from different angles, and the multi-point collection of information in the process of image synthesis is completed. The following conclusions are obtained from the experiments: the synthetic image center is in accordance with the actual center position, and the accuracy of information acquisition is high.
