Embodiment in the present invention, those of ordinary skill in the art are obtained all other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
In order to make full use of Kinect body-sensing technology, it is necessary to which a variety of intelligent identification technologies are added in being emulated in training on electric power
With combination.The present invention identifies the action message acquired in Kinect using template matches and dynamic programming techniques, and according to pre-
The description of finite state machine in case, the state of the action control state machine identified is shifted, complete the control to emulating behavior.
To reach above-mentioned purpose, it is necessary to the limbs nodal information that is obtained to Kinect carries out static segmentation and identification, then
With reference to the continuity of action in time, using template matching method and dynamic programming techniques are combined to identify the one of start-up
Individual action is intended to.These actions are applied in training, also finite state machine need to be utilized in simulation scenario before emulation starts
To be intended to be described to the everything of start-up, the action body of start-up is controlled by state machine after simulation run
Test.
Fig. 1 shows the method flow diagram that training on electric power emulation is realized based on kinect in the embodiment of the present invention, including
Following steps:
S101, the movement posture information based on kinect acquisition start-ups;
Static analysis first is made to the kinect limbs nodal informations obtained, including pre-processes, split, the extraction of border wheel Guo
And the identification of limbs node;Further according to the time course of action, the position of action is obtained in the continuous multiple frames obtained from kinect
Sequence information, thus sequence construct direction of motion vector.Advised finally by this direction of motion vector using template matches and dynamic
Draw the method being combined and carry out the action classification that Dynamic Recognition goes out start-up.
Fig. 2 shows the method state diagram based on kinect enhancing training on electric power experience senses, according to Kinect
The 3D positions for the real-time bone node that forwindows sdk are provided, a certain moment can obtain the position of node, so as to know
Angle and relative position between node.In the case of continuous real-time capture, the motion vector of node can be obtained.Again by
The motion vector of artis come identify the action of start-up indicate.These identification process are included to two legs, two-arm and two hands
Identify, but according to the needs of Simulated training, the identification of leg and arm need to only be judged to lift leg, receive leg, carry arm, drop arm, left swing arm
With right swing arm;And the identification to palm then includes changing hands, clench fist, stretch out the bending of the five fingers and each finger and stretch.
Identification to above-mentioned limb action is all divided into following static identification and two steps of Dynamic Recognition.Known with gesture
Exemplified by not, static state identification key step includes pretreatment, Hand Gesture Segmentation, gestures detection, feature extraction;Dynamic process includes the time
The optimization of sequence and template matches etc..Pretreatment based on Kinect dynamic hand gesture recognitions refers in dynamic gesture training and gesture
Before identification, the depth information flow data and bone nodal information flow data obtained from Kinect is pre-processed, need
The hand to be identified is split from whole data field, to reduce follow-up amount of calculation.Complete and then use in Hand Gesture Segmentation
Border-Following algorithms carry out contour detecting processing to segmented picture.
Border-Following algorithms comprise the concrete steps that setpoint color threshold value first, when less than the threshold value, the pixel
Point is arranged to white.When more than the threshold value, the pixel is configured to certain predefined color (as red).Then distinguish
Each pixel in scanned picture successively from different directions, when the pixel of the left and right adjoined therewith two is different value, then the picture
Vegetarian refreshments is boundary point, so as to find out the profile of image.
Finger tip is distinguished with K-curvature algorithms again, the point on image outline is sequentially stored into array, utilizes K-
Curvature algorithms calculate the approximate curvature at any point.I.e. to the J point point (J) on any profile, point (J) is calculated
Between vector and point (J) and point (J+K) between point (J-K) vectorial angle whether within the specific limits, from
And judge whether it is finger tip.K takes 20 herein, the scope for judging angle be 0 to 55 degree between., can if selected angle is excessive
Causing hand, that section is erroneously identified as finger tip close to arm;And if selected angle is too small, cause when finger is shorter
Cannot be discernable by its.
Because the Kinect frame per second of depth information stream provided is 30FPS, thus even for 2 seconds kind gesture and
Speech, the frame captured in real time constitute a time series close to 60 frames.To same gesture, different people or different time
If completing, the length of the time series is all not quite similar, while continues frame number in a certain direction and be also not quite similar.This is just
Cause to train and identify that difficulty increases, thus be necessary to optimize the length of time series, remove unnecessary information, protect
The characteristic vector for marking the gesture characteristic is stayed, i.e., sampling processing is carried out to the vector after handling after filtering.
S102, the method being combined using template matches and Dynamic Programming go out the action class of start-up come Dynamic Recognition
Not;
The process of dynamic hand gesture recognition is to extract some features to match the action of gesture, present invention selection position and fortune
Dynamic direction vector is as characteristic quantity.Position feature be gesture in each point arrive starting point distance, direction vector for each point with it is previous
The direction of motion that individual point is formed is vectorial (being typically normalized), because position and speed are all scalar, it is impossible to correctly retouch
State the order of hands movement track.And in the case of position is as feature, same gesture, when actuating range is of different sizes, value is different,
So less desirable selection.And speed is for same track, the speed that different people waves the different time is different, no
Gesture can be marked well.So characteristic value is finally used as using direction of motion vector.
Template matching algorithm be it is wherein the simplest realize, that is, establish a template, allow the characteristic of each action
Classification is carried out with template, gesture is differentiated by both similarities, because the time of same gesture has with short, causes to know
Not rate is relatively low.Dynamic time warping (DTW) algorithm need to be used for this, it is a kind of pattern with non-linear normalizing effect
With algorithm, by using to characteristic signal elongate or shorten until consistent with the length of mode standard, to cause and template
Preferably match.Because the application background of the present invention is the experience sense of enhancing start-up, letter can be carried out to the action of operation
Single fixation, therefore the identification of finger movement is carried out using DTW algorithms.
The direction of motion is obtained from finger position twice, and the direction of motion is normalized, finger Y-coordinate below
Y-coordinate less than previous finger represents upward, value 1;Finger Y-coordinate below be more than previous finger Y-coordinate represent to
Under, value is -1;Within the specific limits, then direction value is 0 to the Y-coordinate of finger position twice.The motion sequence of such a finger
(0 ..., 1,1,1 ..., 1,0) or (0 ..., -1, -1, -1 ..., -1,0) is classified as, then the former finger is upward, and the latter represents
Finger is downward.If five fingers are simultaneously downward, then it represents that clench fist;Then represent to stretch the palm upwards simultaneously.The motion sequence of arm is
(0 ..., 1,1,1 ..., 1,0) carry arm is represented;Drop arm is represented for (0 ..., -1, -1, -1 ..., -1,0).The motion sequence of leg is
(0 ..., 1,1,1 ..., 1,0) lift leg is represented;Represent that leg is upright for (0 ..., -1, -1, -1 ..., -1,0).
Equally judge the direction of motion with the difference of the X-axis coordinate of front and rear two positions, by taking right arm as an example, arm X below
The X-coordinate that coordinate is less than previous arm represents inwardly to wave, value 1;The Y that arm Y-coordinate below is more than previous arm is sat
Mark represents outwards to wave, and value is -1;Within the specific limits, then direction value is 0 to the X-coordinate of arm position twice.Such right hand
The motion sequence of arm is (0 ..., 1,1, ..., 1,0) or (0 ..., -1, -1, -1 ..., -1,0), then the former right arm to
Inside wave, the latter represents that right arm is outwards waved.Represent spinning movement with the front and rear wheel Guo area of the left hand palm, area diminish for
1, area becomes greatly -1, and difference in areas is 0 within the specific limits, then motion sequence is that (0 ..., 1,1,1 ..., 1,0) represents rotation,
Motion sequence is (0 ..., -1, -1, -1 ..., -1,0) temporarily without definition.
