Research on Three-dimensional Measurement Method Based on Single-line Structured Light
Line structured light measurement system has the characteristics of fast measurement and high accuracy.Aiming at the problems of large size and limited scanning range of line structured light 3D measurement system,this paper introduces a 3D measurement system using single-line structured light for rotational scanning,and carries out relevant experiments to verify it.First of all,based on the principle of intersection of perspective projection lines and surfaces,a three-dimensional measurement model of line structured light is established to complete the camera calibration as well as the calibration experiments of the optical plane.A projection mode of rotating line structured light is designed,and the calculation of the rotated optical plane is carried out through the rotation angle,so as to complete the measurement of the face shape of the target object.The experimental results show that the system has high measurement accuracy and can improve the portability of the visual measurement system.
