文献中提出了一种大型锻件尺寸的热测量方法，可以实现对大型锻件的远距离、在线、非接触式的尺寸测量，不仅改善了测量的工作条件，而且大大提高了测量精度。该系统以摄像机为主要传感器，测量次数较多。
A thermal measurement was provided for the dimension of the large-size forging workpiece in literature.It can achieve the long-distance,on-line and untouched dimension measure of the large-size forging workpiece,so it not only improves the working condition of measure,but also advances the precision of measure greatly.CCD camera is the main sensor in the system,and it needs more times to measure.In this paper,a new mathematical model is provided for CCD picture-processing,and it can calculate the ellipse section dimension of forging workpiece by two times.
