Abstract
The utility model discloses a mechanical wrist motion capture device, which comprises an outer ring and an inner ring arranged in the outer ring, and the inner ring and the outer ring adopt a rotating manner for connection; a support and a hand-held frame connected with the support are arranged in the inner ring, and a first angle sensor is mounted at the joint between the hand-held frame and the support; a second angle sensor is mounted on the outer ring, and a friction wheel is arranged on the second angle sensor; part of the inner ring is extended out of the outer ring and is in rotating contact with the friction wheel; a forearm bracket is also arranged in the inner ring. When the inner ring rotates relative to the outer ring, the inner ring drives the friction wheel to rotate by means of friction, so that the second angle sensor on the outer ring is driven to rotate, and at the moment, the change of rotational angle along the direction of the forearm can be measured; the first angle sensor at the joint between the hand-held frame and the inner ring can measure the change of the pitch angle of the palm. The technical means of the mechanical wrist motion capture device is simple and easy, and compared with optical capture and electromagnetic capture, mechanical capture has the advantages of low cost, high precision, simple calibration and the like.
Description
Technical field
The utility model relates to motion capture device, relates in particular to a kind of mechanical type Wrist-sport trap setting.
Background technology
Movement capturing technology can obtain the motion state of object in true environment, at aspects such as virtual reality, motion analysis, game and military trainings, all has corresponding application.Mechanical motion trap setting is comprised of a plurality of joints and rigidity connecting rod conventionally, in rotating joint, angular transducer is housed, and can record the situation of change of joint rotational angle.The relative optics of mechanical type trap setting catches and electromagnetism catches, and have the advantages that cost is low, and precision is high, and calibration is simple.People's wrist has three freedoms of motion, two upset frees degree of rotary freedom along orientation arm and palm.Wrist-sport trap setting can record the motion change of wherein one or more frees degree.But more existing mechanical wrist motion capture devices can only catch wrist freedom of motion separately, such as one that only catches in the rotation of wrist or the flip-flop movement of palm.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming and defect of prior art, provides that a kind of cost is low, precision is high, calibrate simple mechanical type Wrist-sport trap setting.
The utility model is achieved through the following technical solutions:
A mechanical type Wrist-sport trap setting, comprises outer ring and is placed in the inner ring in outer ring, and inner ring adopts the mode of rotating to be connected with outer ring;
In described inner ring, be provided with support and hand-held of being connected with support, at hand-held, with support junction, the first angular transducer be installed;
The second angular transducer is installed on described outer ring, and the second angular transducer is provided with friction pulley;
A part for described inner ring is stretched out outside outer ring and with friction pulley and is rotated and contact;
In described inner ring, be also provided with a forearm bracket;
On described the first angular transducer and the second angular transducer, be provided with separately the signaling interface being connected with external equipment.
Described forearm bracket comprises a bottom bracket and the bracket being flexibly connected with bottom bracket.
Described friction pulley adopts rubber wheel.
The utility model has the following advantages compared with prior art:
Inner ring adopts the mode of rotating (mechanical rotation) to be connected with outer ring; Coordinate hand-held of inner ring and the routing motion of the first angular transducer and the second angular transducer; Can measure wrist along angle variation and the luffing angle variation of forearm direction rotation simultaneously.
During work, outer ring is fixed, and when inner ring is when outer ring rotates, inner ring drives friction wheel from rotation by frictional force, and then drives the second angular transducer rotation on outer ring, at this moment can measure along the angle variation of the rotation of forearm direction.Hand-held the variation that can measure palm luffing angle with the first angular transducer of inner ring hinged place.
This device technique means are simple and easy to do, and mechanical type catches with respect to optics and catches and electromagnetism seizure, have with low costly, and precision is high, calibrates the advantages such as simple.
