Abstract: The key issues such as vision sensor, sampling planning are
studied for reverse engineering. For the developed sensor, the
low sensitivity to the incident angle and the high linearity
between the output and the input are carried out. During
digitizing, the adaptive sampling planning method based on the
curvature of surface and the slope of tangent line of measured
point is proposed. After integrating the vision sensor, CNC
milling and relevant software, the reverse engineering system
based on computer vision is developed. The experiment shows that
this system is reliable and efficient.
