Abstract
The invention relates to an intelligent sit-up testing system used for testing a sit-up sports item. Through the video photographing, a human sit-up sports video image is acquired, and is transmitted to a computer to be processed: four corresponding body surface parts of shoulder joint, hip joint, knee joint and ankle joint on the same side of the human body are chosen to be taken as reference points. The connecting straight line of the reference points of the hip joint and the shoulder joint is taken as a basis to establish a rectangular sport joint which synchronously reflects the upper body exercise and also is named as an upper body joint, and the width of the rectangle is the approved upper body curving variation range or effective region. The connecting straight line of the reference points of the hip joint, the knee joint and the ankle joint is taken as a basis to establish a rectangular sport joint which synchronously reflects the lower limb exercise and also is named as a lower limb joint, and the width of the rectangle is the approved lower limb and knee joint curving variation range or effective region. The reference point of the hip joint is taken as a hinge for the joint sport of the human body, the upper body joint and the lower limb joint are connected to form a complete human sit-up sports joint mode. In the completion process of a sit-up action, according to an included angle formed by the effective region, and the upper body joint and the lower limb joint, whether the action is normative or not is judged to count.
Description
Technical field
The present invention relates to a kind of intelligent sit-up test system that is specifically designed to testing human sit-up movement project.When carrying out sit-ups when test, can be automatically, objectively the quality of human body institute execution or standard being carried out intelligence, to declare (examining) disconnected, and according to analysis result self-clocking, counting.
Background technology
At present, the sit-ups test substantially all is to adopt the artificial counting method, and there are shortcomings such as the testing standard disunity, the testing efficiency that cause because of human factor are low in this method.Also have to adopt and utilize the infrared ray lift-off technology device of counting automatically, but this device can only count simple and mechanically, can not judge automatically whether tested personnel test action in test process meets code requirement.In order to reflect tested personnel's test status comprehensively, accomplish automation, intellectuality, accuracy counting, the invention provides intelligent sit-up test system, this system all can be automatically before each counting whether standard is judged to tested personnel's test action, then according to the result count of judgement.
Technical scheme
According to the video image recognition principle, by the video camera mode, obtain human body sit-up movement video image, be transferred to computer and handle: choose homonymy health shoulder joint, hip joint, knee joint, four corresponding body surfaces of ankle-joint position as reference point.Be connected straight line based on hip joint with the shoulder joint reference point, make up a rectangle motion link of reflection human body upper body exercises synchronously, be called the upper body link, this rectangular width is for allowing the excursion or the valid interval of upper body bending.Be connected straight line with knee joint with the ankle-joint reference point based on hip joint, make up a rectangle motion link of reflection human body lower limbs motion synchronously, be called the lower limb link, this rectangular width is for allowing lower limb and knee-sprung excursion or valid interval.With the hip joint reference point is the hinge of health link motion, and upper body link and lower limb link are coupled together, and constitutes a complete human body sit-up movement link pattern.In the sit-ups actions complete process, whether the angle judgement that is become with the lower limb link according to valid interval and upper body link moves standard and then counting.
Beneficial effect
Simple structure, easy operating, testing efficiency height, counting science are accurate, low cost of manufacture, are easy to popularize.
The specific embodiment
By video camera, obtain human body sit-up movement video image, be transferred to computer.Computer is handled video image: on the video image of human body sit-up movement, choose homonymy health shoulder joint, hip joint, knee joint, four corresponding body surfaces of ankle-joint position, reference point as the motion of health link provides crucial reference point for setting up human body link sport video pattern.On the basis of choosing shoulder, hip, knee, four body surface reference points of ankle-joint, on video image (picture), hip joint is connected with the shoulder joint reference point is a straight line, and on this basis, make up a rectangle motion link of reflection human body upper body exercises (this rectangular width is for allowing the excursion or the valid interval of upper body bending) synchronously, be called the upper body link.In kind, hip joint is connected with the ankle-joint reference point with knee joint is a straight line, make up a rectangle motion link of reflection human body lower limbs motion (this rectangular width is for allowing lower limb and knee-sprung excursion or valid interval) synchronously, be called the lower limb link.On video image (picture), be the hinge of health link motion with the hip joint reference point, upper body link and lower limb link are coupled together, constitute a complete human body sit-up movement link pattern.On video image (picture), human body begins to do the motion of drawing the abdomen from dorsal position, lower limb stretch that to be fixed in ground motionless, last one-tenth seat is lifted in the upper body, when the angle of upper body link and lower limb link is spent less than 90, promptly be judged to be by the action code requirement and finished action or the motion that is transformed into seat from dorsal position, counting is finished sit-ups once.On video image (picture), human body falls into dorsal position after seat begins, lower limb stretch that to be fixed in ground motionless, when the angle of upper body link and lower limb link is spent greater than 165, promptly be judged to be to have finished from seat and convert the action of dorsal position to or be reduced to the motion of sit-ups first position by the action code requirement.
Claims (3)
1. intelligent sit-up test system that is specifically designed to testing human sit-up movement project.It is characterized in that: by video camera, obtain human body sit-up movement video image, be transferred to computer and handle: choose homonymy health shoulder joint, hip joint, knee joint, four corresponding body surfaces of ankle-joint position as reference point.Be connected straight line based on hip joint with the shoulder joint reference point, make up a rectangle motion link of reflection human body upper body exercises synchronously, be called the upper body link, this rectangular width is for allowing the excursion or the valid interval of upper body bending.Be connected straight line with knee joint with the ankle-joint reference point based on hip joint, make up a rectangle motion link of reflection human body lower limbs motion synchronously, be called the lower limb link, this rectangular width is for allowing lower limb and knee-sprung excursion or valid interval.With the hip joint reference point is the hinge of health link motion, and upper body link and lower limb link are coupled together, and constitutes a complete human body sit-up movement link pattern.In the sit-ups actions complete process, whether the angle judgement that is become with the lower limb link according to valid interval and upper body link moves standard and then counting.
