Description
Technical field
The present invention relates to gait analysis field, exactly refer to a kind of three-dimensional gait analysis instrument.
Background technology
Human motion is that nervous system is controlled 1000 polylith muscle and had the rhythm and pace of moving things to shrink, and drives 200 polylith skeletons around the result of more than 100 joint synergy movements.Although life science has made great progress in recent years, it is also very far away that but range simulation brain is controlled the process of limb motion, therefore the researcher such as rehabilitation medicine, Science of Physical Culture and Sports generally adopts the macroscopic motion of observer's limbs to diagnose human motion function disease, assessment human body recovery process, instructs athletic training and selection.
The method of existing Measurement and analysis gait has following several:
1, footprinting: be to make to detect by an unaided eye, do some simple time and space records.Sprinkle on the ground pulverized limestone, allow person to be measured walk on the ground sprinkled with pulverized limestone to record simultaneously person's walking to be measured apart from discrete time.Walked rear observation and measurement sprinkled with the ground footprint of pulverized limestone, thereby drawn the result of gait analysis.There are a lot of significantly defects in this method, such as: time is long; Need to expend a large amount of manpowers; Analysis be take subjectivity as main, and accuracy is lower; The data that obtain are less; Clinical report hand filling, wastes time and energy and easily makes mistakes.
2, video method: human walking procedure is absorbed by video equipment (CCD photographic head), then frame by frame pointwise carry out dot-matrix analysis, its advantage is that equipment is simple, experimenter's gait is more natural, but because its analyzing and positioning mainly relies on manually, higher to operation requirements, error ratio is larger, and can only carry out two dimensional surface analysis, the degree of accuracy of three-dimensional spatial analysis can not be guaranteed.
3, infrared light type: accept the Infrared of skin-marker transmitting or reflection by infrared camera, and send out according to corresponding model analysis, carry out three-dimensional reconstruction, thereby draw the 3 D motion trace that partes corporis humani divides.Its advantage is technology maturation, and data result is accurate, simple and quick; Shortcoming is to have requirement to pasting the position of reflective spot, pastes to such an extent that will definitely directly not affect measurement result; In measuring process, can not there is foreign body gear between reflective spot and photographic head, comprise tested personnel self, so personnel can not be accompanied or assist in tested personnel side.Otherwise affect data acquisition; Higher to environmental requirement, need to be equipped with the room what a area is larger, photographic head installs after angle, can not arbitrarily change; Expensive, operating process is responsible for, and majority is used at laboratory, seldom sees in clinical use, has limited to a certain extent phase popularization.
4, ultrasonic type: the principle of ultrasonic type is similar to infrared light type, the ultrasonic emitting probe being carried by body surface sends ultrasound wave, accepts, according to certain model setting through ultrasound wave receiving transducer around, carry out three-dimensional reconstruction, draw the 3 D motion trace of human body.Its advantage is that equipment price is relatively cheap, operates also relatively simply, and data are also more accurate; But ultrasound wave easily reflects, must eliminate the interference of object around, surrounding is had relatively high expectations, simultaneously because gauge point volume is larger, the gauge point quantity that body once carries has certain restriction, only the suitable human body Segmental analysis that carries out.
