Embodiment Construction

[0047]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 the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0048] The field of view of the existing technology in the horizontal direction is 270°, which is larger than that of small animals, while the maximum vertical projection field of view is only -20°-60°, which cannot meet the needs of some neurological research on mice given visual stimulation from above. In order to expand the vertical field of view of the virtual reality of small animals, the present invention selects a projector 2 with replaceable lenses, replaces the ordinary medium-telephoto lens with a fisheye lens, and forms a projection structure with the spherical screen 1 without any reflect...

Abstract

The invention provides a panoramic presentation method and device, and the method comprises the steps: presenting a panoramic image through employing a combined structure of a single fisheye projectorand a spherical screen on hardware, and employing the geometric relation between a fisheye lens and the position of a viewer and an equidistant projection transformation, and enabling the 180-degreefisheye projection to show 720-degree environment information to a viewer in the center of the spherical screen so as to greatly simplifying the image conversion process and realizing zero distortion. Besides, in terms of software, according to the 720-degree panorama one-step generation method based on the single virtual camera in software, complex steps of collecting six images by a plurality of cameras, synthesizing a cubic map and then converting the cubic map into a panorama are not needed, the vertex position of a scenery is directly adjusted in the process from a 3D space to a 2D image, and a final panorama is generated in one step. The close combination of software and hardware enables the image conversion speed to be improved by more than 6 times, so that the real environment ofthe content can be displayed, and a viewer can feel immersive and can perform real-time conversion to interact with the viewer.

Description

technical field [0001] The invention belongs to the field of virtual reality, and in particular relates to a panorama presentation method and a device thereof. Background technique [0002] Due to ethical reasons, many neuroscience experiments cannot be carried out on the human body, and the brain research of small animals has brought great help to technicians in exploring the mechanism of brain function and opening up new fields of neuroscience. Neuroscience behavioral experiments are often based on the free movement of animals in a specific space, such as the maze to test memory ability, the cross elevated test to explore behavior, and the three-box device to test social barriers, etc. International standard experimental paradigms, but these behavioral experiments are difficult to further explain the neural principles . The elucidation of neural principles needs to be applied to large-scale recording devices with many fixed positions, such as two-photon microscopy, in viv...
