A method for measuring standing long jump distance based on image recognition

Abstract

The invention relates to a method for measuring standing long jump distance based on image recognition, which belongs to the technical field of sporting goods. It is characterized in that it includes a jumping mat (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), and the following steps are also included: Step 1001, taking the original picture ; Step 1002, black and white processing is carried out to original picture; Step 1003, carry out perspective transformation and pixelation processing to original picture; Step 1004, test starts; Step 1005, take secondary image; Processing; step 1007, performing perspective transformation and pixelation processing on the secondary picture; step 1008, performing pixel comparison; step 1009, obtaining the long jump distance. This image recognition-based standing long jump distance measurement method confirms the long jump performance through image recognition, and the measurement is accurate while avoiding the waste of personnel and low cost.

Description

technical field [0001] The invention relates to a method for measuring standing long jump distance based on image recognition, which belongs 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 scores by a dedic...

[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 scores by a dedicated score recorder. Therefore, the traditional test method needs to occupy at least two to three additional score recorders, resulting in a certain waste of personnel. At the same time, the work efficiency is relatively low. 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
