测量物体的等角线有许多成熟的方法,用于大物体测量的光学方法有影栅云纹和投影云纹法。本文不采用云纹法,而采用投影栅方法,将在物体上发生畸变的栅输入到图 There are many sophisticated methods of measuring the isometry of objects. The optical methods used for the measurement of large objects include moiré and projection moiré. This article does not use the moire method, and the use of projection grid method, the distortion of the object in the grid input to the map
