Method and device thereof for presenting three-dimensional image

Abstract

The invention relates to a method and a device thereof for presenting a three-dimensional image, which belongs to the technical field of the digital three-dimensional multimedia, and aims at solving the problems such as the display, the observe mode, the display gap and the strabismus cone distortion. The method comprises the following steps that: the position of an image display screen and a user observation point is determined according to the space layout and the space structure; the image data is undertaken the image edge-blending splicing; the image data is undertaken the correction of the three-dimensional image strabismus cone; and the image after being processed is displayed in a projection way. The method ensures the completeness and beauty of the displayed image, enlarges the application way of the digital sand table, really realizes the three-dimensional perspective effect of the projected image, and greatly improves the application capacity of the digital sand table on the aspects such as the urban plan and design exhibition.

Description

technical field [0001] The invention belongs to the technical field of digital three-dimensional multimedia, and in particular relates to a method and a device for displaying three-dimensional images. Background technique [0002] As a new form of model expression, the digital sand table has received more and more attention. Compared with the traditional physical sand table, it has the following characteristics: [0003] (1) The digital sand table can seamlessly zoom in and zoom out [0004] The scale of the physical sand table is fixed. For a sand table with a scale of 1:250,000, the highest Mount Everest is only 35cm high on the sand table. The overall city model of Beijing in the Beijing Planning Museum has an area of ​​about 600 square meters and a scale of 1:750. However, the tallest 250-meter China World Trade Center Phase III is only 33cm high, and ordinary buildings are even smaller, and the 30-meter-high building is only 4cm high. The situation of other large-are...

Problems solved by technology

[0016] The technical problem to be solved by the present invention is to improve the display form and viewing mode of the current multi-dimensional image, eliminate the problem of gaps existing in the image during the projection process, and the problem that the image has a squint cone distortion in the squint state during the high-altitude viewing process, so that the image During the playback process, provide users with a more vivid and vivid three-dimensional image viewing experience
