extinction fringe

First,the outer edge of the fabric sample is identified;next,the contour line from the panoramic raster stripes image is extracted;then positioning and computing the height of raster stripes to obtain the 3D coordinates of sampling points in raster stripes;finally,the 3D fabric drapability image of the specimen is reconstructed using bicub.

首先识别出试样的边缘轮廓,然后从全景光栅图像中提取等高线信息,对光栅条纹进行定位,计算出光栅条纹所在位置的空间高度,从而得到试样上光栅取样点的三维坐标数值,再利用双三次贝赛尔曲面重建试样悬垂形态的三维图像。

The laser stripe image gathered in the structured light measurement system is needed to be processed effectively.

在结构光测量系统中需要对采集到的激光条纹图像进行有效处理。

Firstly,the radial laser stripe is projected sequentially on the various positions on the tire tip.

详细说明了获取车轮胎冠切点的不同方法,提出1种基于立体视觉和激光投影的车轮切平面测量方法,该方法依次向车轮胎冠上不同位置投射径向激光条纹,并通过条纹提取,平面拟合和坐标转换方法获取车轮胎冠切点,进而计算出车轮的切平面方程。
