Optical calibration and measurement methods for sit-up tests

Abstract

The invention relates to an optical calibration and measurement method for sit-up tests, comprising the following steps: S1, a plurality of mark lines with different reflectance from a background areaare arranged in the test area and a plurality of quadrilaterals are formed, and with preset length-width ratio of each quadrilateral in the area where the body is located being different from other quadrilateral; S2, when no one is present, the standard test area image is captured by the camera, and the body standard image area is delimited and processed by the algorithm to obtain the standard algorithm graph; S3, a real-time test area image of a test area with a test person is captured, a real-time image area of a body in the real-time test area is found, and the real-time algorithm graph isprocessed to obtain the real-time algorithm graph; S4 AND operation is performed on that real-time algorithm graph and the standard algorithm graph to obtain the effective algorithm graph, and judging and count the sit-up motion of the tester according to the changes of the mark lines in the effective algorithm graph. The method has good test experience, and the test efficiency and the test precision can be guaranteed.

Description

technical field [0001] The invention relates to a calibration and measurement method for a physical fitness test, in particular to a calibration and measurement method for a sit-up test. Background technique [0002] At present, with the development of society and economy, the improvement of people's awareness of health, and the changes in the international situation, the country's enhancement of the overall national physique has been raised to a strategic level. In this context, there is an urgent need for more efficient and accurate monitoring of the national physique. [0003] In the "National Physique Measurement Standards Manual and Standards (Adult Part)" issued by the State Sports General Administration, sit-ups are included as one of the test items for national physique. [0004] However, in the traditional counting method for sit-ups, manual monitoring and counting is usually used, so the test efficiency is not high, and the error rate is large. Long-term repetitiv...
