Description

Three-dimensional physical model animation playing device based on naked eye persistence of vision

Technical field:

the utility model belongs to the technical field of persistence of vision and stroboscopic effect principles, and particularly relates to a device for playing animation by utilizing a stroboscopic effect of lamplight in rotation of a static physical model based on naked eye persistence of vision. The visual persistence and the stroboscopic effect are combined, and the pictures which are continuously switched are fixed, so that the effect of playing the animation is achieved.

The background technology is as follows:

the phenomenon of persistence of vision, also known as the "afterglow effect", was first proposed in his study report, "persistence of vision of moving objects", by university of london, uk, professor peter, mark, luo Gete in 1824. When the naked eyes observe a scene, light signals are transmitted into brain nerves, a short period of time is required, after the light effect is finished, visual images do not disappear immediately, the residual vision is called "afterimage", and the phenomenon of vision is called "persistence of vision". Vision pauses are common in our lives, as when viewing high-speed running automobile wheels, the wheels are found to be rotating forward, stationary or inverted. People also invent a film-retaining disk, a trotting horse lamp and the like by utilizing the vision pause phenomenon. The film is also produced by utilizing the persistence of vision, 24 frames/second is a common format of the film, 25 static pictures are continuously played in 1 second, and continuous dynamic video is seen by naked eyes.

Principle of stroboscopic effect: according to the definition of JGJ/T119 building Lighting terminology Standard, the stroboscopic effect (Strooscopic effect) is a phenomenon that under light irradiation varying at a certain frequency, the motion of an object observed by a person is made to appear different from the actual motion thereof. The stroboscopic effect is caused by flickering of the light source, which is an unstable visual phenomenon caused by light stimulus whose brightness or spectral distribution fluctuates with time. In short, the stroboscopic effect is a phenomenon in which the observed movement of an object appears to be stationary or different from its actual movement state under irradiation of light varying at a certain frequency. He may give the human eye a flickering sensation. The thermal inertia of the luminous body of the heat radiation light source is large, so that the flickering feeling is not obvious, but this phenomenon of the gas discharge lamp is more remarkable. When the gas discharge lamp is used as an illumination light source, if the object to be illuminated is in a rotating state and the rotating frequency is just an integral multiple of the power frequency, the rotating object looks as if it is not rotating. This phenomenon in which the observed movement of an object under irradiation with light varying at a certain frequency shows a different behavior from its actual movement is called stroboscopic effect. The stroboscopic effect of the LED light source is particularly pronounced because of the thermal inertia of the incandescent lamp and the afterglow effect of the gas discharge lamp, which in turn is responsive to the voltage and current of the LED and to the light output.
