In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with attached drawing to the present invention
Each embodiment be explained in detail.However, it will be understood by those skilled in the art that in each embodiment party of the present invention
In formula, in order to make the reader understand this application better, many technical details are proposed.But even if without these technical details
And various changes and modifications based on the following respective embodiments, the application technical solution claimed also may be implemented.
The first embodiment of the present invention is related to a kind of methods of trapezoidal correction.The method of laser television focusing is applied to
Laser television, wherein laser television includes laser television main body and curtain, and the laser television camera lens in laser television main body is used for
By laser projection on curtain.The detailed process of the method for the trapezoidal correction is as shown in Figure 1:
Step 101: obtaining the adjustment that mobile terminal is sent and indicate information, adjustment instruction information is by mobile terminal according to acquisition
To curtain on display picture determine, wherein mobile terminal and laser television communicate to connect.
Specifically, mobile terminal can be the terminal with camera, for example, smart phone, PAD, removable computer etc..
User can select the mobile terminal for being suitble to practical application according to the use demand of itself.Between the mobile terminal and curtain
In present embodiment with no restrictions, it can arbitrarily be selected according to practical application.
Mobile terminal can be shot on the curtain of laser television after receiving user and inputting the instruction for determining trapezoidal correction
The display picture of display, it is to be understood that the display picture of mobile terminal shooting should contain the complete display picture on curtain
Face, to ensure that subsequent movement terminal can accurately determine adjustment instruction information.Mobile terminal can be to the display picture of acquisition
It is analyzed, for example, determining the shapes and sizes of display picture using edge detection method, and determines the shape of curtain
Shape and size, so as to calculate the parameter for carrying out trapezoidal correction according to the shape of display picture.Laser television can be from connecing
The parameter of trapezoidal correction is obtained in the adjustment instruction information received.
It should be noted that before obtaining the adjustment instruction information that mobile terminal is sent, laser television and mobile terminal
Establish communication connection.Communication connection, such as bluetooth, wifi can be established between laser television and mobile terminal wirelessly
Mode, can also be by the way of wire communication connection, such as using data line connection laser television and mobile terminal.
Step 102: according to adjustment instruction information adjustment display picture, so that the shape of display picture is standard rectangular.
Specifically, adjustment instruction information in may include trapezoidal adjustment algorithm and determination trapezoidal correction ginseng
Number, laser television obtain adjustment instruction information, trapezoidal correction algorithm in available adjustment instruction information and this is trapezoidal
Parameters information in correction algorithm, laser television is according to the trapezoidal correction algorithm and parameters information to being incident upon on curtain
Display picture carry out trapezoidal correction.
Embodiment of the present invention determines adjustment instruction information, laser electricity in terms of existing technologies, by mobile terminal
Information is indicated depending on obtaining the adjustment, and according to adjustment instruction information adjustment display picture, so that the shape of display picture is in mark
Quasi- rectangle accelerates laser television due to the step of being adjusted to laser television manually without user, reduce manual operation
The speed for carrying out trapezoidal correction accurately, improves the display effect of laser television so that trapezoidal correction becomes simpler；Simultaneously
Due to calculating adjustment instruction information without laser television, the processing function in laser television will not be occupied, to improve laser
The processing capacity of TV；And the camera without increasing the picture shown on acquisition curtain, it further reduced laser television
Cost.
Second embodiment of the present invention is related to a kind of method of trapezoidal correction.Second embodiment is to the first embodiment party
The further refinement of formula, in second embodiment of the invention, after getting adjustment instruction information, according to the ginseng of trapezoidal correction
The Adjusting Shape of display picture to be projected is standard rectangular by number information, and display picture adjusted is incident upon curtain
On.The detailed process of the method for the trapezoidal correction is as shown in Figure 2.
Step 201: obtaining the adjustment that mobile terminal is sent and indicate information, adjustment instruction information is by mobile terminal according to acquisition
To curtain on display picture determine, wherein mobile terminal and laser television communicate to connect.
Step 202: obtaining the parameter information of trapezoidal correction in adjustment instruction information.
