REAL-TIME IMPLEMENTATION OF CALCULATING DEPTH INFORMATION BY IMAGE SEQUENCES ACQUIRED FROM THE PARALLEL MULTI-VIEWPOINTS
-
摘要: 引入了平行多视点的概念,从平行多视点获取的多幅图象中可以求得深度信息。通过利用图象的FFT变换,将时域中很难解决的问题变换到频域中来解决,避免了复杂的匹配运算,极大地简化了求取图象点、面深度信息的问题,并且提高了深度求取的实时性、全面性和准确性。介绍了算法原理及特点,并给出了实验结果及分析。

Abstract: A new algorithm of calculating depth information by image sequences acquired from the parallel multi-viewpoints is discussed. By means of orthogonal transformation of image (in this paper, the authors use fast Fourier transformation), the matching problem, which is difficult to solve in time domain, is put into transformation field in frequency domain. -
