| According to human visual perception characteristics,Display technology expresses visual information(text,graphics,images,etc.)through digital means.As the main window of information display and human-computer interaction,display technology has been widely used in many fields.The integration of display technology and modern science and technology expands the realization of information display and strengthens the ability of human beings to obtain visual information.Display technology has made great contributions to information science,but there are still some limitations in three-dimensional display.Display technology still needs to be applied in some special information acquisition scene.Based on the above situation,higher requirements are put forward on the display technology.Under the above background,the rotary display technology and its application are studied.The main research work is as follows:(1)The theoretical basis and technical principles of rotary display are analyzed,a speed adaptive display control method is proposed.POV(Persistence of Vision)rotary imaging of three-dimensional images is studied.Image analysis program and display control program are designed to enable the system to display static or dynamic panchromatic images.Imaging quality of the system was optimized from the perspective of display resolution.(2)A circular rotary display system was designed and implemented.The system uses DC motor to drive the rotating parts to rotate.The main controller uses Xtensa32-bit LX6 dual-core processor.The rotating parts use wireless power supply to improve the service life of the system.Using external sensors to obtain speed information,the image can be displayed adaptively according to speed.(3)Software and hardware of the system are tested.Experimental results show that the circular rotary display technology has great advantages in three-dimensional image display.The three-dimensional image with strong three-dimensional depth of field can be observed by setting the pixels outside the three-dimensional image without display content.A POV rotary display imaging quality evaluation model for three-dimensional images is proposed to evaluate the imaging quality of the circular rotary display system.(4)The application of rotary display technology in the popular science display of complex three-dimensional scenes and the application of special information display based on rotating parts are analyzed.As a new display technology,rotary display technology has great development space and application potential.This paper uses its rotation characteristics to expand the application scene of display technology,and provides a new solution for three-dimensional display problems and special information display problems based on rotating parts. |
