Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0028] The invention proposes a method for constructing a virtual scene on the surface of the moon. Taking the simulation process of the soft landing area on the lunar surface of Chang'e-3 as an example, as follows: figure 1 Shown, the concrete implementation method of the present invention is as follows:

[0029] Step 1, panorama mosaic;

[0030] The Chang'e-3 panorama left and right cameras captured 58 pairs of images at each detection point on the lunar surface in a horizontal 360° circle and at different pitch angles, that is, 58 images taken by the left and right cameras respectively. To solve problems such as the particularity of the image, the panoramic image of the Chang'e-3 panoramic camera was mosaiced using t...

Abstract

The invention discloses a construction method for a virtual scene of the lunar surface. The construction method comprises the steps that a Chang'e 3 panoramic left-right camera is utilized to perform horizontal annular photographing on detection points of the lunar surface, through different pitch angles, so multiple pairs of images are obtained, and panoramic inlaying is performed on the obtained multiple pairs of images, so the panoramic image of the lunar surface is obtained; a lunar surface simulated scene model is constructed; a constructed lunar surface starry sky model and a constructed lunar surface landform model are re-projected to a sight plane; three-dimensional real-time rendering is performed on the lunar surface starry sky model and the constructed lunar surface landform model re-projected to the sight plane, so a video signal is produced, and the video signal is displayed horizontally and stereoscopically on a cylindrical screen projection screen; through a graphic workstation, data preprocessing is performed on image data of a Chang' e 3 descending camera, so that a video signal is obtained; besides, the obtained video signal is transmitted to the projection display system for vertical projection display on a projection screen of a ground curtain.

Description

technical field [0001] The invention relates to the field of virtual reality technology and its application, in particular to a method and device for truly and quickly simulating a lunar surface scene in a three-dimensional display environment. Background technique [0002] Using the lunar rover to carry out patrolling and detection on the complex lunar surface, realize the information exchange between the lunar rover 380,000 kilometers away and lunar scientists, engineers and technicians on the ground, and complete the lunar surface patrolling and detection mission of Chang'e-3 safely and accurately. Establish a virtual reality human-computer interaction system for lunar surface scenes, build a three-dimensional visualization platform with strong sense of reality, good immersion, and high real-time performance, integrating lunar surface topography, starry sky environment, and time information, and assist lunar scientists to fully understand the lunar rover surrounding detec...
