Abstract

An orthogonal projection sampling method is proposed in this paper and is applied in the reconstruction of incomplete data field by using the prior knowledge algorithm based on the modified ART, by which the satisfying reconstruction results can be obtained even with less sampling directions and limited sampling angular range. The Mean Square Error (MSE) and peak value between the origin field, the reconstructed field using orthogonal projection sampling method and traditional projection sampling method are analyzed with the numerical simulation of computer. The results indicate that the orthogonal projection sampling can reduce the MSE greatly in the reconstruction of incomplete data. Thus our researches provide a new means for the reconstruction of incomplete data field.
