Embodiment three
The embodiment of the invention provides a kind of bore hole 3D image display method, and it is that example describes in detail that present embodiment has two display screens with display unit, and promptly display unit comprises first display screen and second display screen.
As shown in Figure 4, this display packing comprises:
The basic principle that 2D changes the 3D function is through the scene of analysis 2D, sketches the contours the close shot image in the middle of the scene and give prominence to, and simultaneously distant view image is carried out postposition, and for example, personage etc. are preposition, and background environment and object carry out postposition; Further, the part preceding of same object is preposition, after part rearmounted, thereby real-time implementation 2D image transitions is a 3D effect.
Depth of field processing and control module adopts the spaced pixels image-forming principle, the 3D three-dimensional signal is calculated be separated into the signal corresponding with each display screen.For being calculated according to required 3D stereo display result's close shot distant view, the 3D three-dimensional signal is separated into first signal and secondary signal in the present embodiment.
Further, first display screen is divided into first pixel cell and second pixel cell, and first pixel cell shows that second pixel cell does not show; Second display screen is divided into the 3rd pixel cell and the 4th pixel cell, and the 4th pixel cell shows that the 3rd pixel cell does not show.
For example, as shown in Figure 5, after calculating separation, 1 to 9 picture element signal separates, and first display screen receives 1,3,5,7 and 9 picture element signals, i.e. first signal; Second display screen receives 2,4,6 and 8 picture element signal, i.e. secondary signals.And first display screen receives only the close shot picture signal, and then concrete processing method has following three kinds:
Method one: if in the former 3D rendering signal, 1 to 9 picture element signal is the close shot picture signal, then 1 of first display screen, 3,5,7,9 picture element signals are the respective pixel signal of former 3D rendering signal, distribute to first pixel cell on the display screen; Rest of pixels on first display screen does not have picture signal, is second pixel cell, when actual displayed, is light transmission state, allows the display image of second display screen to pass through; Preferably, first pixel cell and said second pixel cell are spaced apart on first display screen.
And second display screen is divided into the 3rd pixel cell and the 4th pixel cell.2,4,6,8 picture element signals on second display screen for the picture signal of the respective pixel of former 3D three-dimensional signal is carried out after the translucent processing and handle picture signal through certain depth of field, be the 4th pixel cell, the 4th pixel cell display image signals.Rest of pixels on second display screen, promptly the 3rd pixel cell does not have picture signal, is light transmission state.The 3rd pixel cell and the 4th pixel cell are spaced apart on second display screen, and, corresponding first pixel cell of the 3rd pixel cell, corresponding second pixel cell of the 4th pixel cell.Like this, when showing, the 4th pixel cell of second display screen and the combination of first pixel cell on first display screen demonstrate the three-dimensional 3D rendering of the depth of field.
Method two: if in the former 3D three-dimensional signal; 1 to 9 picture element signal is the distant view image signal; Then this moment is not to the pixel distribution diagram image signal of the correspondence position of first display screen; The pixel that is these correspondence positions is second pixel cell, when actual displayed, is the full impregnated light state, allows the display image of second display screen to pass through; Second display screen, 2,4,6,8 picture element signals are the respective pixel signal of former 3D three-dimensional signal, corresponding the 4th pixel cell, and rest of pixels is the 3rd pixel cell, no picture signal.
Method three: if in the former 3D three-dimensional signal, the existing close shot picture signal of 1 to 9 picture element signal has the distant view image signal again, then answers associated methods one and method two respectively first signal and secondary signal to be handled.
Adopt the spaced pixels image-forming principle to carry out the separation of 3D three-dimensional signal, can effectively deepen the demonstration depth of field of first display screen and second display screen, strengthen the 3D display effect.
Distance between step 103, infrared induction module induction user and the display screen also sends to depth of field processing and control module, says exactly, should be the distance between the infrared induction module induction user and first display screen and sends to depth of field processing and control module.
The infrared distance measurement principle can be summed up as basically to be measured the round required time of target of infrared ray, goes out distance through infrared ray propagation velocity and atmospheric refraction coefficient calculations then.Because directly Measuring Time is relatively more difficult, normally measures the phase place of continuous wave, survey phase formula rangefinder so also can be described as, certainly, pulse distancemeter is arranged also.
