Spherical screen device and image generating method thereof

Abstract

The invention discloses a spherical screen device and an image generating method thereof. An image is corrected by following steps: according to a corresponding radian curve with the radian at 90 degrees, uniformly dividing the radian curve of a spherical screen into multiple sections; according to a pixel of a plane image needing to be displayed, similarly dividing a straight line, corresponding to the radian curve, of the plane image into multiple sections identical to the sections of the radian curve in number; valuing an image parameter of the first point in the plane image to a third point in the plane image; on the radian curve, linking the second point, corresponding to the first point, of the position of the image to be displayed with the center of a sphere, and taking the point located in a plane of the plane image as the third point. By adopting image correction, image restoration on the spherical screen is realized, and the spherical screen device and the image generating method thereof are particularly applicable to image displaying realization on LED spherical screen devices at 360 degrees.

Description

technical field [0001] The invention relates to a 360-degree spherical LED screen device and an image forming method thereof, in particular to a spherical screen device and an image forming method thereof. Background technique [0002] In the prior art, the dome screen device has always been a technology that large-scale film and television entertainment facilities try to evolve. With the current improvement of LED display technology, it has become possible to set up LED dome screens. The LED 360-degree ball screen movie device emits rays according to the center of the cube to the direction of 8 vertices, cuts the spherical surface into 6 equal areas, and forms a fixed frame and an external structural frame in this way. The driver circuit board is installed on the fixed frame and the external structure frame, thereby forming an LED ball screen device that faces the inside of the ball screen to emit light and play images. [0003] However, in the existing LED dome screen dev...

Problems solved by technology

[0003] However, in the existing LED dome screen devices, rows and rows of LED lamps and lamp panels are usually assembled. Since the current image technology converts a plane image into a spherical image with a certain radian, the existing LED lamp panel There is no way to overcome the problem of uneven LED arrangement in the display, and at the same time, it cannot solve the display of the arc, which will cause serious image distortion. Therefore, it has not been possible to realize large-scale 360-degree LED dome screen devices in industrialization in the prior art.
