Problems solved by technology

This timing method is very inconvenient. Not only does it require the runners to carry the logo to affect the running movement, but it also usually needs to install various radio frequency devices that can identify the runner's logo on the finish line. The installation is troublesome and the work is cumbersome, which is not conducive to convenient and fast running. timing

Embodiment Construction

[0026] Below, in conjunction with accompanying drawing and specific embodiment, the present invention is described further:

[0027] Such as figure 1 Shown, a kind of timing method of middle-distance running motion, comprises the following steps of carrying out successively:

[0028] Step 1: Preset at least one color identification, and establish an RGB array and the upper and lower limits of the RGB array for each color identification, for example, the lower limit of red is (0,0,200) and the upper limit is (90,90,255), and the establishment of the RGB array The upper limit and the lower limit are for the purpose of allowing the computer to create a mask for the color logo to identify the color logo more accurately. At the same time, a one-to-one mapping relationship is established between each color identifier and the athlete, so that the athlete can be identified through the color identifier. The number of color identification settings means that the computer can identify ...

Abstract

The invention relates to a timing method for middle and long-distance running. The method sequentially comprises the following steps of 1, presetting color identifiers; 2, obtaining a frame image; step 3, preprocessing the frame image to obtain a processed image; 4, processing the contour area of the image to obtain an effective image; 5, identifying the convex hull of the effective image, and obtaining the angular point of the convex hull and the abscissa value of the angular point; 6, comparing the horizontal coordinate of the leftmost corner of each effective image with the horizontal coordinate of the central axis in sequence according to the frame time of the effective image; and 7, determining that the time of a final athlete arriving at the end line is the frame time of the final timing frame image. By adopting the method, the timing is convenient and the accuracy is higher. Meanwhile, the result of the method is not affected by the runway chaos condition. Therefore, the timingfor the simultaneous running of a large number of athletes can be tested.

Description

technical field [0001] The invention relates to the technical field of sports timing, in particular to a timing method for middle and long-distance running. Background technique [0002] In sports such as long-distance running, the lap timing is usually performed by manually pinching the watch in the past. Later, radio frequency technology is gradually used to realize timing. Laps and timings are figured out. This timing method is very inconvenient. Not only does it require the runners to carry the logo to affect the running movement, but it also usually needs to install various radio frequency devices that can identify the runner's logo on the finish line. The installation is troublesome and the work is cumbersome, which is not conducive to convenient and fast running. timing. Contents of the invention [0003] In view of the deficiencies in the prior art, the object of the present invention is to provide a timing method for middle and long distance running, which can s...
