Image-recognition-based distance measuring device and measuring method of standing long jump

Abstract

The invention, which belongs to the technical field of sporting goods, provides an image-recognition-based distance measuring device and measuring method of standing long jump. The measuring device iscomposed of a jumping carpet (3) and a distance measuring mechanism (1). A controller and a shooting module controlled by the controller are arranged in the distance measuring mechanism (1). Besides,the measuring method includes: S1001, shooting an original picture; S1002, carrying out black-and-white processing on the original picture; S1003, carrying out perspective transformation and pixelation processing on the original picture; S1004, starting testing; S1005, shooting a secondary image; S1006, carrying out black-and-white processing on the secondary image; S1007, carrying out perspective transformation and pixelation processing on the secondary image; S1008, carrying out pixel comparison; and S1009, obtaining a long jump distance. According to the image-recognition-based distance measuring device and measuring method of standing long jump, the long jump performance is determined based on the image recognition; the measurement precision is high; and personnel wasting is avoided and the cost is low.

Description

technical field [0001] The invention relates to a standing long jump distance measuring device and a measuring method based on image recognition, belonging to the technical field of sporting goods. Background technique [0002] The standing long jump is a sport that can reflect the physical coordination and explosive power of the human body during exercise, and also reflects the individual's physical fitness to a certain extent. During the school period, the standing long jump is usually a must for a campus physical fitness test test items, so it has a broad mass base. [0003] In the traditional standing long jump test, it is usually completed in the sand pit. The students participating in the long jump test stand at the take-off point and then jump into the sand pit. Then at least two other testers fix the measuring stick at the take-off point and the jumping point respectively. To read the scores at the end of the test, it is generally necessary to manually record the sc...

Problems solved by technology

[0003] In the traditional standing long jump test, it is usually completed in the bunker. The students participating in the long jump test stand at the take-off point and jump into the bunker, and then at least two other testers fix the measuring stick at the take-off point and the jumping point respectively. Generally, a dedicated score recorder is required to manually record the score, so the traditional test method needs to occupy at least two to three additional score recorders, resulting in a certain waste of personnel, and at the same time, the work efficiency is relatively high. low

[0004] In the prior art, there is also a standing long jump test device with certain achievements automatically recorded, but the existing test device is relatively huge in size, difficult to move, and expensive at the same time, which is not a small investment for the school. Increased the financial burden of the school to a certain extent
