Author(s): 
Pages: 210-214
Year: Issue:  2
Journal: JOURNAL OF BEIJING INSTITUTE OF TECHNOLOGY

Keyword:  三维坐标测量编码图案投影图案识别;
Abstract: 为改进后的图案编码的识别和三维坐标的计算提供理论和技术依据.测量物体的三维坐标,恢复物体三维面形图.用3灰度级块状图案构成编码图案投射到被测物体上,通过新的解码算法实现对应点之间的匹配,并用坐标变换方式计算三维坐标.找出了对应点并给出对应点的三维坐标公式,测出了简单物体的三维坐标,恢复了三维面形.所用方法具有操作简单,数据获得快,易于实现的特点.
