Background

The results of the current standing long jump test are mostly measured by manual measurement and infrared equipment, the measurement modes have the problems of inconsistent test standards, incapability of automatically corresponding testers and test results, low test efficiency, large workload of referees and the like, and particularly, the infrared measurement equipment needs to work in a live mode, so that certain danger is brought to the safety of the personnel participating in the test.

Manual measurement: the test result of manual measurement is directly related to the basic quality and skill of the measuring staff, and the measured results are inconsistent due to inconsistent subjective standards of different measuring staff. Meanwhile, the precision of measuring tools such as a tape measure and the like can also influence the measuring result. Under the condition that a large number of testers participate in the test together, the workload of the testers is large, the results need to be recorded manually, and the test efficiency is low.

Infrared sensing measurement: infrared sensing measurements rely on the cooperative operation of an infrared transmitter and an infrared receiver. When standing long jump tester is in the middle of infrared emitter and infrared receiver, the infrared ray of infrared emitter transmission is sheltered from by the tester, and infrared receiver can't receive infrared signal, shelters from position department and is the position that standing long jump tester both feet were located promptly to calculate the score. The system also calculates the score when the infrared ray is shielded by the non-measuring object. And the result and the precision of the infrared measurement are related to the density of the infrared emission matrix. The infrared sensing measuring equipment has the common problem that the infrared sensing measuring equipment is easily interfered by foreign matters to misreport scores, and the infrared sensing equipment for standing long jump test has low measuring score precision due to cost reasons.

The common problem of the standing long jump testing method and the device is that the free standing long jump performance cannot be accurately measured based on the consistent standard, the automation and intelligence degrees are low, the testing efficiency is low, and the workload of a measurer is large.

Particularly, the standing long jump test method and device need to rely on a take-off wire as a basis for take-off and measurement of scores, and cannot realize take-off test at any place in a test area because accurate score measurement cannot be performed. However, the standing jump of the jumping line is relied on, because the jumping is not accurate to step or jump over the line, the tester usually takes the jump at a certain distance from the jumping line, on one hand, the existence of the jumping line brings the pressure of the worker for stepping the line and making a foul, and the athletic ability of the tester cannot be fully exerted, on the other hand, the test result is not the real standing jump distance of the tester, but only the distance between the landing point and the jumping line after the tester takes the standing jump, and the distance is usually smaller than the real standing jump distance, so the test result reflects not the real ability and level of the tester.

Disclosure of Invention

The invention aims to provide a method and a device for testing the free standing long jump, which change the current mode of the test of the free standing long jump, do not need to set a jump wire, test personnel freely jump at any place in a test area, use a camera and machine vision to carry out rule judgment and score measurement of the free standing long jump test, identify the jump point of the free standing long jump of the test personnel, calculate the distance between the jump point and the landing point as the score of the standing long jump, and realize automation, standardization and intellectualization of the free standing long jump test.

And then judging the normativity of the test process action: whether the single foot falls to the ground or not.

And after the tester lands on the ground, judging that the tester lands on a single foot if the moving distance of the single foot exceeds the landing distance threshold within the landing time threshold range.

If the result is judged to be that the single foot falls to the ground, the test result is invalid.

Then judging whether other parts of the body contact with the ground or not: whether the buttocks touch the ground or not and whether the buttocks support the ground or not.

After the tester lands on the ground, the buttocks of the tester lands on the ground within the threshold range of the landing time, and the buttocks of the tester lands on the ground within the range behind the feet.

And after the tester lands, judging that the tester holds the ground by hands and is behind the two feet within the range of the landing time threshold value.

If the buttocks touch the ground or hold the ground by hands, the touch position or the hold position of the buttocks is taken as the landing point. And if not, taking the point closest to the jumping point in the two feet of the landing transient frame as the landing point. And calculating the straight line distance between the landing point and the take-off point to obtain the free standing long jump test result.
