Use Edge Detection Method and Matlab for Time Measurement in Athletics Field
Yiting Weng · 2022
Even though the technology of real-time recording in the Athletics field is highly developed, it is still not easy for people to calculate the time from a recorded video. People can only estimate the time with their eyes if a randomly chosen video is given. So in this paper, the method will be introduced to provide a fundamental choice to solve such a problem. The process will be based on the Matlab program as it is a convenient tool providing an essential technique for image processing. For the detail of this method, the Edge Detection method and Hough Transform are used to locate the edge of athletes and tracks to find out the time score from a running race video. Even though the result may have an error in about 0.03 seconds, it is much more precise than calculating from the human eyes and, as a result, can have practical use with further development.
