| Abstract: | The principle of an imaging sensor used for on line measurement of workpieces produced by high speed hot forming is presented. And a new compensation method of the synthesis error of on line measurement of the image sensor signal is given by proof test and theoretic analysis of the major factors which resulted in the errors. Through this new method, the difficulties in direct on line measurement of some errors are overcome by means of the on line estimated value of correlative parameters which are easy to determine, and the compensated amount of the corresponding error is given. Its application to the hot forming testing field showed that the measuring precision of this new method is satisfactory. |
