Long jump detection method and device

Abstract

The invention discloses a long jump detection method and a detection device, which realize the long jump detection based on vision, and obtains the actual long jump distance of a long jump person by obtaining the image data of a long jump area for analysis and detection. The problems that current long jump detection cannot guarantee actual long jump distance precision, and equipment is high in manufacturing cost, inconvenient to carry and the like are solved.

Description

technical field [0001] The invention belongs to the field of sports equipment, and in particular relates to a long jump detection method and detection device. Background technique [0002] In traditional standing long jump measurement, physical education teachers usually measure the distance with a tape measure on ordinary flat ground, record the scale on the ground with chalk, and record the long jump results by visual inspection. There are certain misjudgments and missed judgments, and the long jump measurement method is limited by the venue. [0003] In recent years, some automatic long jump measurement devices based on infrared sensor arrays have appeared one after another. These devices usually require a fixed long jump area for installing sensors, which makes the measurement device not easy to move, and cannot be changed at any time. The flexibility is poor. In the prior art, laser radar and a spirit level are also used to realize long jump detection. This type of met...

Problems solved by technology

[0003] In recent years, some automatic long jump measurement devices based on infrared sensor arrays have appeared one after another. These devices usually require a fixed long jump area for installing sensors, making the measurement device not easy to move, and the site cannot be changed at any time, which has poor flexibility.

In the prior art, laser radar and a spirit level are also used to realize long jump detection. This type of method requires a relatively flat ground as the long jump site, and laser radar equipment as the detection equipment. The disadvantage of this type of method is that the laser radar equipment is relatively expensive, and Only one-dimensional data is easily disturbed by environmental factors; there are also methods that use a camera plus a jumping mat, add a pressure sensing device to the jumping mat and then trigger the camera to take pictures to detect people's long jumps. Instantly trigger the pressure sensor on the jumping mat to take pictures to judge the person's landing point. This method uses the image vision method, but the jumping mat is needed to trigger the camera to take pictures, and it is not based on pure image visual judgment. This method is suitable for long jumpers. Some other actions such as standing on the ground after a long jump, or standing unsteadily and falling to the ground, etc., these illegal actions cannot be detected
