[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

Embodiment 1
[0042] The present invention provides a long-jump detection method, and the steps of the method are as follows: figure 1 shown, can be divided into two parts, calibration and measurement;
[0043] Calibration:
[0044] like figure 2 As shown, this is an example of calibration. First, a site is arbitrarily selected, and a long jump detection device is set up. The long jump detection device provides a field of view, and the field of view corresponds to a long jump area 100; at the same time, the long jump detection device The depth image and visible light image of the long jump area 100 can be obtained;
[0045] Subsequently, a static depth image and a static visible light image of the long jump area 100 are obtained, the static depth data of the long jump area 100 is obtained by analyzing the static depth image, and the static visible light data of the long jump area 100 is obtained according to the static visible light image, wherein, The static depth data refers to the di...

The invention discloses a long jump detection method and a detection device, which realizes the long jump detection based on vision, obtains the actual long jump distance of the long jumper by analyzing and detecting the image data of the long jump area, and solves the problem of the actual long jump distance in the current long jump detection The accuracy cannot be guaranteed, and the equipment is expensive and inconvenient to carry.
Description
technical field [0001] The invention belongs to the field of sports equipment, and in particular relates to a long jump detection method and a detection device. Background technique [0002] In traditional standing long jump measurement, physical education teachers often measure the distance with a tape measure on ordinary flat ground in advance, record the scale on the ground with chalk, and record the long jump result by visual inspection. The judgment of students' take-off and crossing the line is only determined by the naked eye. 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, so that the measurement device is not easy to move, and cannot be changed at any time. The site has poor flexibility. In...
