Long jump distance measuring method based on double lasers

Abstract

The invention provides a long jump distance measuring method based on double lasers. The method comprises the steps of verifying the information of an examinee, and stopping the examination if the examinee does not pass the examination, if so, performing an examination, measuring the long jump distance of the examinee through the laser distance measuring plate and the laser distance measuring instrument, and acquiring the test distance, obtaining test distances of limited times of the examinee, taking out the farthest test distance as an examination score of the examinee, and reporting generation information and examination time, and acquiring the test distance by moving the laser distance measuring instrument to a position needing to be tested. The collected distance data is more accurate.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a long-jump ranging method based on dual lasers. Background technique [0002] The standing long jump is one of the items that must be tested every year in the <<National Student Physical Health Standards>> test from junior high school to university graduation. The test method of the standing long jump: It is required to take off at rest behind the take-off line, and stepping on the line is not allowed. The test is conducted three times, and the one with the best record is the final result. In the traditional test, the manual measurement method requires more than two testers to measure repeatedly through the tape, and then read and record. The work efficiency is low, the workload of repeated measurement is heavy, it is easy to cause fatigue of the testers, and the subjective factors of the testers are affected Test Results.

In the traditional test, the manual measurement method requires more than two testers to measure repeatedly through the tape, and then read and record. The work efficiency is low, the workload of repeated measurement is heavy, it is easy to cause fatigue of the testers, and the subjective factors of the testers are affected Test Results

[0003] Existing comparative document CN201720416447; title is: a standing long jump rangefinder based on dual laser rangefinders: it uses dual laser rangefinders for distance measurement, and this method mainly uses a tripod to place it on the foothold for measurement, because The foothold is on the bunker, which may be uneven and cannot be guaranteed to be flat, so that the two emitted lasers are not on the same horizontal plane. By manually rotating the angle value, there is a large error in the angle value, and there is an error in the calculated distance.

The accuracy of the data obtained by this method is not high
