The identification object of movement originate in position represented by start amplitude threshold value and identify object set vector threshold and/
Or in angle threshold value;The identification object of position movement is from position represented by start amplitude threshold value to reaching amplitude threshold institute table
During the position shown, identify object in set vector threshold and/or angle threshold value;The identification of position movement
Object reaches position represented by amplitude threshold and identification object in set vector threshold and/or angle threshold value
It is interior;And currently there is the identification in addition to negative identification and other than keeping identification to be in ongoing state (in other words, the rail of movement
Mark or displacement amplitude are increasing).When reaching above-mentioned rule, then cueing track malfunctions.In other words, if identification object is in the body
In the motion process at position always not in the threshold range of identification parameter setting, and represented by the identification object
Position movement generates track and/or displacement during the motion, then will not prompt to malfunction.
Keeping identification, whether position movement is maintained under a certain state during the motion (for example, keeping straight for identification
Vertical or one bending angle of holding), it prompts to malfunction if being not maintained under the state.The identification object for keeping identification includes described three
An angle at least one vector and/or three vectors in a vector between two vectors.Identification parameter setting
One or more threshold values, the threshold value include the vector threshold of three vectors and the angle threshold value of the angle, identification ginseng
Number is determined according to the identification object uses vector threshold and/or angle threshold value.Keep identification reaches rule are as follows: the position is dynamic
The identification object of work is always in set vector threshold and/or angle threshold value.Keep what is identified to reach rule if not reaching,
Then prompt the corresponding mistake for keeping identification.
For displacement identification and negative displacement identification, although described here as towards displacement rather than the identification of object-oriented
, but whether displacement identification and negative displacement identification actually also need recognition site movement in lasting motion state, if position
Movement is not in lasting motion state and then interrupts identification, directly prompt mistake;Or it is re-started since current location
Identification.
Displacement identification identifies whether object reaches scheduled direction of displacement and shift length for judging, mentions if not up to
Mistake is shown.The identification object of displacement identification includes one or more of three skeleton points.Preferably, the position is specified to act
One skeleton point.(direction of displacement can map to the pros of the X-axis in three-dimensional coordinate for identification parameter setting shift length, direction of displacement
To, X-axis negative direction, Y-axis positive direction, Y-axis negative direction, Z axis positive direction, Z axis negative direction, without calculating specific direction of displacement)
And start amplitude threshold value.The start amplitude threshold value of displacement is the value in 0 to 1.For example, start amplitude threshold value can be set to 0.2,
And indicate that position movement starts or displacement identification is opened when the displacement of specified skeleton point is more than the 20% of setting shift length
Begin.The recognition rule of displacement identification includes reaching rule and optional different mistake rule.Displacement identification reaches rule to refer to
It is consistent to determine the direction of displacement being arranged in the moving direction and identification parameter of skeleton point, and the shift length of a persistent movement is greater than
Equal to the shift length being arranged in identification parameter.Different mistake rules includes that the displacement of specified skeleton point is less than start amplitude
When threshold value, origination action insufficient amplitude is prompted;Specified skeleton point displacement amplitude is more than the shifting of start amplitude threshold value, specified skeleton point
The direction of displacement being arranged in dynamic direction and identification parameter is consistent and the shift length of a persistent movement is less than in identification parameter
The shift length of setting, then insufficient amplitude is reached in prompt.
Negative displacement identification identifies whether object reaches scheduled direction of displacement and shift length for judging, if reaching
Prompt error.Similar with displacement identification, identification object includes one or more of three skeleton points.Preferably, the portion is specified
One skeleton point of position movement.Identification parameter setting shift length, (direction of displacement can map in three-dimensional coordinate direction of displacement
X-axis positive direction, X-axis negative direction, Y-axis positive direction, Y-axis negative direction, Z axis positive direction, Z axis negative direction) and start amplitude threshold value.It is no
Determine displacement identification to reach the direction of displacement being arranged in moving direction and identification parameter of the rule for specified skeleton point consistent, once
The shift length of persistent movement is more than or equal to the shift length being arranged in identification parameter and currently has in addition to negative identification and protect
It holds the identification other than identification and is in the ongoing state of movement (in other words, track or displacement amplitude are increasing).When reaching
Above-mentioned rule, then cueing track malfunctions.In other words, if identification object does not press the identification during movements of parts of the body
The direction of displacement of parameter setting is mobile or moving distance is greater than the shift length that the identification parameter is set, then does not prompt
It is wrong.
Above-mentioned identification item is arranged at least one position acted movement, by least one position act and it is described extremely
Motion file of the identification item of few position movement as the movement, the motion file and movement number are associatedly stored
In the standard operation database.
In a specific embodiment, deep-knee-bend is acted, identification item is provided with to trunk, left leg and right leg.Trunk
Identification item include keep identification and displacement identification.In the holding identification of trunk, identification object is only that head center arrives neck
The primary vector at vertebra center is correspondingly arranged the parameter of the primary vector, and saves by the primary vector of trunk in deep-knee-bend mistake
Standard procedure vector library in journey is for subsequent match.When the primary vector of the trunk acquired in real time is more than the threshold of primary vector
Value, then it represents that body is not kept upright, and error is prompted.Herein, due to the characteristic of trunk, when in the vertebra of head center to neck
When the primary vector of the heart is kept upright, it generally can directly assert the vertebra center of neck to the secondary vector at the backbone center of trunk
Also it is kept upright, the threshold value for only setting a vector improves the efficiency of subsequent real-time error to reduce subsequent calculation amount.
In the displacement identification of trunk, identification object is the skeleton point at the backbone center of trunk, and corresponding identification parameter is should
The predetermined displacement distance of skeleton point and scheduled direction of displacement (direction is Y-axis negative direction).When the backbone center of trunk is negative along Y-axis
When direction movement is more than preset distance, then it represents that the identification of position movement is reached.If the backbone center of trunk is along Y-axis negative direction
It is mobile be less than predetermined displacement apart from when, then it represents that the insufficient amplitude of position movement.
Left leg is provided with negative displacement identification, for reminding in deep-knee-bend knee no more than tiptoe.The negative of left leg is displaced
In identification, identification object is the artis of left knee, and identification parameter is predetermined displacement distance, scheduled direction of displacement (direction Z
Axis positive direction) and start amplitude threshold value.When left knee along Z axis positive direction move more than predetermined displacement apart from when, then prompt to indicate
Position stroke defect.When left knee move along Z axis positive direction be less than predetermined displacement apart from when, then it represents that the knowledge of position movement
Do not reach.The identification item of right leg is identical as left leg, and it will not be described here.
In there are some specific embodiments, has for deep-knee-bend, push-up etc. and bob works, it can be only to coming and go back to centre
Process set and identified.For example, movement when only squatting down to deep-knee-bend carries out the setting of identification item and identification is entangled
It is wrong;Movement when only to push-up prostrate carries out the setting and identification error correction of identification item, thus can be further reduced action recognition
Calculation amount to increase the real-time of error correction.
