| Abstract: | This paper describes a new method of finding the point of intersection between the straight line and the free curve utilizing the pixel distinguishing function of computer upon the monitor. Using this method,the pixel on the curve is regarded as the target. Following the tracks of the straight line of interpolating computations point by point and distinguishing every pixel to catch the objectives,the goal of obtaining intersections will be completed. This method provides a new solution to the problems of obtaining intersections between the straight line and the free curve encountered in engineering. |
