Abstract: The Measuring System of human traumatical surface by applying computer graphics(SYSTEM)is developed on the methods of palm and coordinate paper, and complied with C language. The show of the SYSTEM is in the form of menu Prompt, There are many merits in high speed, simple operation,lower expenses, more accuracy, avoiding the emergence of conjecture and so on. The import resources are including scaner and camera. The SYSTEM allows you to calibrate the distortion of screen and tO identify the image forms of TIF or PCX. The SYSTEM measures the areas of human traumatical surface by eclating the pixels in RAM. This research achievement has been applied on many traumatical cases of forensic clinic in our institute.

Key words: computer, trauma, surface measurement
