摘要：
This paper proposes a 3D laser scanning technology for the pinhole camera with lens distortion. On the basis of the pinhole camera mathematical model, we improve the extraction algorithm of Harris corner points, and introduce the professional 2D RAC calibration, 3D reconstruction, and 3D volume calculation. With the help of stepper motor, and the camera, we can capture a series of images and obtain the object 3D surface information. Furthermore, we use the line laser with Gaussian distribution as the measurement illuminant, and select the samples at the peak of intensity distribution. This brings both high accuracy and speed of measurement.
