摘 要:To inspect the surface quality of steel bar,we designed an automatic system including linear camera and laser.Through the comparison among kinds of cameras,we select linear CCD to our system.The laser is also chosen by us with its high luminance and performance.Through a series of computation,we select the appropriate camera lens to our device.At last,we draw the whole detection system.This device has been used well and provides a good foundation for prospective image processing.
