To keep the technical problem to be solved in the present invention, technical solution and advantage clearer, below in conjunction with attached drawing and tool
Body embodiment is described in detail.
The present invention provides one kind aiming at the problem that Learning Studies of the existing people to marine organisms are confined to observation level
Control the method and system of virtual sea biology.
Embodiment one
As shown in Figure 1, the method for control virtual sea biology provided in an embodiment of the present invention, comprising:
S101 obtains the gesture information of user；
S102, judges whether the gesture information obtained is included in preset gesture, if so, being believed using the gesture obtained
The target organism that breath controls in pre-set virtual sea biosystem is moved.
The method that virtual sea biology is controlled described in the embodiment of the present invention, obtains the gesture information of user；Judgement obtains
Gesture information whether be included in preset gesture, if so, being controlled using the gesture information obtained pre-set virtual
Target organism in marine organisms system is moved.In this way, by the interactive form of gesture control and virtual sea biosystem
It combines, observation operation is carried out to marine organisms by gesture and control operates, for example, rotation, overturning, mobile etc., make user
Carried out with virtual sea biology it is directly interactive, can effectively solve the problem that people can not contact in person, operate marine organisms thus can not
The difficulty of marine organisms is furtherd investigate, so that cognitive learning marine organisms rise to interactive experience level by observation level, thus
Condition caused by water environment and environmental restrictions can not be detached from by abolishing marine organisms.
In the present embodiment, the target organism is the biology that will operate of the user in virtual sea Systematic selection.
In the present embodiment, the gesture information that the gesture information of user can be obtained by acquiring unit, and will acquire is uploaded
To virtual sea biosystem, it is added in frame data；Wherein, the acquiring unit can be sensing equipment, and the sensing is set
It is standby to be docked with virtual sea biosystem.
In the present embodiment, before sensing equipment is docked with virtual sea biosystem, also need to determine virtual sea biology
System is suitable for the gesture used；And plug-in unit needed for adding the docking sensing equipment in virtual sea biosystem.
In the present embodiment, the sensing equipment is docked with virtual sea biosystem includes:

In the present embodiment, four kinds of preset gesture objects can be called by frame gesture list: draw a circle, sweep away, downward, preceding
It stretches, and corresponding with corresponding function, in practical applications, preset gesture can be determined by actual conditions.
In the present embodiment, in observing interface, sweeping gesture corresponds to marine organisms model and rotates counterclockwise, and gesture of drawing a circle is corresponding
It rotates clockwise, downward gesture correspondence downwardly turns over, and extension gesture correspondence is flipped up；In simulated operation interface, gesture of protracting
Corresponding master control marine organisms biology advances, and gesture of drawing a circle is corresponding to be retreated, and sweeping gesture correspondence moves to right, and downward gesture moves to left.In reality
In the application of border, the corresponding function of every kind of gesture can be determined by actual conditions.
In the present embodiment, marine organisms rotation, overturning, movement all around can control by these four gestures.
In the specific embodiment of the method for aforementioned control virtual sea biology, further, what the judgement obtained
Whether gesture information is included in preset gesture, if so, controlling pre-set virtual sea using the gesture information obtained
Target organism in foreign biosystem carries out movement
The gesture information for the present frame that will acquire and the gesture information of particular frame before compare, and determine description hand fortune
Dynamic characteristic value；
Judge whether the characteristic value for describing hand exercise is greater than the control threshold of preset first gesture；
If more than the gesture information then obtained is first gesture, and pre-set using the gesture information control obtained
Target organism in virtual sea biosystem is moved, wherein the first gesture is any hand in preset gesture
Gesture.
In the present embodiment, when carrying out gesture identification, the movement of hand need to be analyzed, it is specific: the present frame that will acquire
The gesture information of gesture information and particular frame before compares, and determines the characteristic value of description hand exercise, for example, rotation is sat
Mark, rotation angle, displacement.
In the specific embodiment of the method for aforementioned control virtual sea biology, further, to exclude environmental disturbances
Gesture identification rate is promoted, is that four kinds of gestures set corresponding control threshold, the control threshold set needed for different gestures has difference
It is different, the reference method that control threshold is set as
Rf=(EquivDiameter/2)+σ
Wherein, Rf indicates that gesture feature radius, EquivDiameter are indicated with gestures detection region with the equivalent of area circle
Diameter, σ indicate control threshold.
In the present embodiment, control threshold needed for gesture of drawing a circle are as follows: least radius 5mm, minimum angles 1.5* radian；To assistant
Control threshold needed for gesture are as follows: minimum downward velocity 50mm/s, least displacement 3mm in 0.1 second；Control threshold needed for sweeping gesture
Are as follows: minimum length 150mm, minimum downward velocity 1000mm/s；Control threshold needed for gesture of protracting are as follows: minimum speed forward
50mm/s, least displacement 5mm in 0.1 second.
In the specific embodiment of the method for aforementioned control virtual sea biology, further, in the hand for obtaining user
