Topic.
First embodiment
Fig. 3 is refer to, is a kind of flow chart of avoidance projecting method that the present invention is provided.The method is related to control device
100 and mobile terminal 200, communication is capable of achieving between control device 100 and mobile terminal 200.
Method includes：
First grid picture is projected to view field by step S310, control device 100, there is barrier in view field.
First grid picture is stored in control device 100, and its lines is equally distributed grid.View field is nature
There is a shelter in screen under environment, such as pure color metope, screen, its front, such as air-conditioning, potted plant, cupboard and other block screen
Article.Under initial environment, control device 100 will simultaneously be projected on shelter.
Step S320, the control mobile terminal 200 of control device 100 shows the first grid picture, and obtains user in movement
The of the first area of the covering barrier that the position based on barrier selects in the first grid picture of display in terminal 200
One positional information.
Communication connection is set up between control device 100 and mobile terminal 200.The control mobile terminal 200 of control device 100 shows
Show the first grid picture.The first grid picture can be prestored in mobile terminal 200, control device 100 sends the first net of display
To mobile terminal 200, mobile terminal 200 calls the first grid picture and shows for the order of trrellis diagram piece.Also may be used in mobile terminal 200
Do not store the first grid picture, under this implementation method, control device 100 by the first grid picture transfer to mobile terminal 200,
And control mobile terminal 200 to show the first grid picture.
Mobile terminal 200 should be provided with input equipment, such as Touch screen, mouse, button, can receive user to first
The operation that grid picture is carried out.User is elementary cell to the general grid in scheming of operation of the first grid picture, by such as
The choosing of large area frame, the modes such as single grid are selected to carry out.The first grid picture and control device 100 of the display of mobile terminal 200
In the first grid picture equal proportion of view field's projection, in order to user according to the Obstacle Position before view field in movement
The first area of covering barrier, the first area is selected to believe by first position in first grid picture of the display of terminal 200
Breath is represented.
First position information can be first area edge pixel point coordinates or the first area institute of the first grid picture
There is pixel point coordinates.If first area edge pixel point coordinates, then can be differentiated according to edge pixel point coordinates, picture
Rate, dimension of picture calculate all pixels point coordinates.

The pixel point coordinates at place, is that follow-up projection is got ready.
Step S330, control device 100 obtains picture to be projected.
Picture to be projected is different from foregoing first grid picture, and the first grid picture is mainly used in being pre-set, and
Picture to be projected is used for actual displaying.Picture to be projected can be pre-stored within control device 100, also can by control device 100 from
Network is downloaded, or is transmitted to control device 100 after being downloaded by mobile terminal 200.But pending picture should be with the first grid picture
With same size, i.e. length-width ratio, and with identical resolution ratio.
Step S340, control device 100 determines pending area corresponding with first position information in picture to be projected.
Control device 100 according to the first position information obtained from mobile terminal 200, i.e. position coordinates before barrier,
Determine the region of covering barrier during the corresponding first area of picture to be projected, i.e. actual projection.
The dispaly state of pending area is revised as Transparence Display by step S350, control device 100.
The dispaly state of pending area is revised as transparent, each pixel of pending area should actually be carried out
Brightization treatment.Here hybrid algorithm can be used.Commonly used algorithm is AlphaBlend to hybrid algorithm at present.Computing formula is such as
Under：
Assuming that piece image is A, another transparent image is B, then go to see A through B, it appears that image C be exactly B
With the mixed image of A, if the transparency of B images is alpha (value is 0-1, and 1 is fully transparent, and 0 is completely opaque),
Alpha mixed formulations are as follows：
R (C)=(1-alpha) * R (B)+alpha*R (A)
G (C)=(1-alpha) * G (B)+alpha*G (A)
B (C)=(1-alpha) * B (B)+alpha*B (A)
R (x), G (x), B (x) refer to the RGB component primary color value of color x respectively.From the equations above it is recognised that Alpha its
It is in fact a numerical value for decision mixed transparent degree.Using Alpha hybrid technologies, it is possible to achieve the Vitrification management of picture.
According to above-mentioned formula, it is known that, alpha value is set to 1, fully transparent image can be obtained.Therefore, can wait to locate
Addition alpha passages on the basis of the RGB triple channels of each pixel in region are managed, i.e., using AlphaBlend algorithms, while setting
It is 1 to determine alpha value, can be processed as pending area transparent.Through picture to be projected after treatment in projection, picture is in itself
The influence of texture, color to barrier will drop to minimum, can reach optimal drop shadow effect.
