摘要
研究了基于二维平行轮廓线的前列腺三维表现重建问题。采用Roberts边缘检测算子检测前列腺的边缘,提取其轮廓线。分析了BPL1算法在处理相信轮廓线无匹配部分时存在的缺陷。文章采用BPL1算法和相信轮廓线同步前进法相结合的方案襀了前列腺表现的三维重建,给出了实验结果。实验表明重建的三维表面清晰、准确。
This paper implements the surfaces reconstruction of prostate. The arithmetic operator of Roberts is used to get the contours of prostate. After analyzing the imperfect of the algorithm of BPL1 on having no.match part between two contours, this paper adds the algorithm of synchronized operation to BPL1 and applies it to the reconstruction of prostate. The result of prostate＇s surfaces is clear and exact.
