Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, right The present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, and It is not used in the restriction present invention.
Below in conjunction with specific embodiment the present invention implemented and is described in detail:
Embodiment one:
Fig. 1 shows the flowchart of the sketch learning method based on virtual reality that the embodiment of the present invention one provides, For convenience of description, illustrate only the part relevant to the embodiment of the present invention, details are as follows:
In step S101, receive the virtual reality sketch learning content that user selectes, in the study of this virtual reality sketch Appearance includes: virtual sketch object figure and sketch step.
In embodiments of the present invention, user, before sketch learns, selects the virtual of correspondence according to the painting ability of self Reality sketch learning content, this virtual reality sketch learning content can leave virtual reality sketch learning content in be concentrated, its In, location mode can be classified according to ages or painting ability, such as, is divided into according to ages: child, green grass or young crops are less Year and adult, be divided into according to painting ability level: primary, intermediate and senior, thus, facilitate user to enter according to self-demand Row is selected, it is achieved learn targetedly.
In embodiments of the present invention, sketch step includes: virtual sketch map, pen part solution action message and portion's action Dynamics information.Wherein, virtual sketch map is the sketch map of each decomposition step, and pen part solution action message is a description side in portion To and describe lines length.
In step s 102, the head movement direction of detection user, enter with preset direction according to user's head movement direction Row coupling, this preset direction includes: the first preset direction and the second preset direction.
In embodiments of the present invention, the head movement direction of user can be detected by nine axle sensors, pass through user Head movement direction can obtain the visual angle of user, and then provide the user the virtual reality sketch learning content of correspondence.Root According to preset direction, head movement direction user being detected is mated with preset direction, owing to user is during sketch Head can occur the rotation in other directions, be not each rotation direction be effective head movement direction, it is therefore desirable to By mating with preset direction, after matching effective head movement direction, further according to the preset direction mated, carry For corresponding virtual reality sketch learning content.
In step s 103, according to the preset direction of coupling, the virtual reality sketch learning content of correspondence is exported to user.
In embodiments of the present invention, according to reality application and the custom of user, the most effective head movement direction bag Including comes back hopes vegetarian noodles object forwards, and bows and paint, therefore, the first preset direction be user's head lift prestige to Front, the second preset direction is that user's head lowly sees the direction of paper on desktop.
Further, mating when the head movement direction of user is the first preset direction, then export described virtual to user Sketch object figure, this first preset direction is that user's head lifts prestige forwards.
Mating when the head movement direction of user is the second preset direction, then export sketch step to user, and second presets Direction is that user's head lowly sees the direction of paper on desktop.
In embodiments of the present invention, when the head movement direction of user be user's head lift prestige forwards with first preset Direction is mated, and now, exports virtual sketch object figure so that user can see that the sketch object of required description, thus saves Extra layout studio, add the cost of still life.When the head movement direction of user is that head lowly sees paper on desktop Direction is mated with the second preset direction, now, exports sketch step, and user, after seeing virtual sketch object figure, needs to bow The paper of desktop is described, now, exports sketch step for user, it is simple to user paints with reference to sketch step, Help user learning sketch, improve learning efficiency.
Preferably, under the second preset direction, determine paper region on desktop by default photographic head;
Obtain the image of paper region on desktop, according to the image of paper region on desktop, currently learned The sketch image of habit progress;
According to the sketch image of described current study schedule, the described sketch step of corresponding output.
In the present embodiment, in order to assist user to learn by oneself sketch further, user bow every time describe when, I.e. under the second preset direction, determine paper region on desktop by default photographic head, thus, it is possible to accurately acquire Image on paper, on acquisition desktop after the image of paper region, namely obtains the element of the current study schedule of user Tracing picture, compares, thus with the virtual sketch map in sketch step according to the sketch image of the current study schedule of this user Can obtain closest to sketch step, corresponding sketch step is being exported to user, user is according to corresponding sketch step Suddenly sketch study can be carried out.
Embodiment two:
Fig. 2 shows the flowchart of the sketch learning method based on virtual reality that the embodiment of the present invention two provides, For convenience of description, illustrate only the part relevant to the embodiment of the present invention, details are as follows:
