利用OpenGL实现全景图像跳转的算法设计

针对现有全景图像跳转技术的不足,研究中提出一种利用专业的图形程序接口OpenGL来实现的全景图像全新跳转方法。该方法将采集到的全景图像进行坐标解析,再采用几何变换消除图像的变形,随后进行图像的投影变换,然后进行视口变换,得到屏幕坐标。当视图屏幕点击位置发生变化时,则可以和全景坐标进行匹配判断,实现图像的跳转。通过对比实验验证,结果表明所设计的算法使得跳转时间从50ms降低到30ms,节省了40%的时间。

In view of the shortcomings of the existing panoramic image jump technology,this paper proposes a new panoramic image jump method using professional graphics program interface OpenGL.By this method,the collected panoramic image is analyzed,and then the geometric transformation is used to eliminate the deformation of the image.Then,the projection transformation of the image is carried out,and then the screen coordinates are obtained by the transformation of the views.When the click position of the view screen changes,it can match with the panoramic coordinates to realize the image jump.The experimental results show that the algorithm reduces the jump time from 50 ms to 30 ms and saves 40%of the time.
