摘要
直接线性变换(D irect LinearTransformation)解法是建立观测点像方空间坐标和同名点物方空间坐标之间直接线性关系的算法。本次试验通过使用普通数码相机,并应用2维直接线性变换进行了建筑物变形监测的试验研究,试验结果表明,使用普通数码相机代替常规测量方法能够满足变形监测三等精度要求。
Ab The Direct Linear Transformation （DLT） is arithmetic to establish direct linear relationship of points between the image space coordinate system and the object space coordinate system. By using a common digital camera, two -dimensional DLT is tested to monitor tbe structural deformation, which indicates that 3 - order precision requirement for deformation monitoring can be achieved by using common digital cameras instead of traditional survey methods.
