Reconstruction system and method for sheet three-dimensional surface of flexible body

Abstract

A system for rebuilding surface 3D image of flexible body in thin sheet form consists of a background light source; a sample clamping device with a top point for bending sample here; an image collecting device to collect side projection image of sample at top point; a sample driving device and a computer for controlling the driving device, receiving series of sample side projection image, processing and analyzing the series, picking up side projection image height data of each image and montaging them as per collecting order for forming 3D stereo image of sample surface . 本发明提出了一种用于薄片型柔性体表面三维重建的系统和方法。该系统包括一背景光源，用于发出均匀且具有一定亮度的后向漫反射光；一试样夹持装置，其上夹持有待三维重建的一试样，该试样夹持装置具有一顶点，所述试样在该顶点处弯折；一图像采集装置，用于采集所述试样在所述顶点处的侧面投影图像；一试样驱动装置，其驱动夹持在所述试样夹持装置上的所述试样均匀地通过所述顶点；一计算机，其控制该试样驱动装置动作，同时接收该图像采集装置采集到的所述试样的侧面投影图像的序列，对所述图像序列进行处理和分析，提取每一帧图像的侧面投影高度信息，并按照采集顺序拼接得到所述试样表面的三维立体图像。
