步法

This is an untouched measuring way. The cameras are calibrated in the way of RAC two steps, first. With the polynomial interpolation, the pictures catched from the steel plate are treated to detect the edge in subpixel with a cross window arithmetic operators, which can fit non uniform illumination, keep the edge character and do filter in a better way. Three-dimensional scenery could be rebuilt from the two-dimensional pictures with the methods of least square fitting and contradictorily clairvoyance. Thus, the distance and its variance of two points in the given position of the plate can be achieved. It is expected that this study can provide a new and useful tool to the research on the theory of distortion of line heating.

This algorithm lights five pixels in a loop between the coordinate information of line's start and end points. Therefore, the speedof generating of straight line can be accelerated. Compared with the four-step, it is the speed that increased by about 20% while the complexity is almost the same. Meanwhile the five-step still maintains the precise of the traditional line scan conversion algorithm.
