Embodiment Construction

[0035] A panoramic camera imaging device and method based on multi-GPU high-speed interconnection of the present invention will be described in detail below in conjunction with specific embodiments.

[0036]A panoramic camera imaging device based on multi-GPU high-speed interconnection proposed by the present invention includes 4 wide-angle binocular cameras, which are respectively the first wide-angle binocular camera 1, the second wide-angle binocular camera 2, and the third wide-angle binocular camera. Eye camera 3 and the fourth wide-angle binocular camera 4, the placement position of the four-way wide-angle binocular camera is as follows figure 1 shown. The 4-way wide-angle binocular cameras are centered on point o and are on the same horizontal plane xOz. Each camera rotates around the y-axis perpendicular to the horizontal plane xOz. The angle between the 4-way wide-angle binocular cameras is 90°. Each camera The camera angle is perpendicular to the xOz plane. The hor...

Abstract

The invention provides a panoramic camera imaging device and method based on high-speed interconnection of multiple GPUs. The device is composed of four wide-angled binocular cameras; the four wide-angled binocular cameras are arranged in the same horizontal plane in a 90-DEG included angle pairwise; each set of wide-angled binocular cameras is provided with CPUs and GPUs for processing respectively acquired images; furthermore, various GPUs are interconnected through a PCI-E; therefore, fast inter-image data interaction is realized; splicing and fusion of a high-definition image can be completed effectively; a seamlessly spliced binocular stereoscopic panoramic video can be fast obtained; and real-time watching of the high-definition binocular stereoscopic panoramic video can be realized.

Description

technical field [0001] The invention relates to the field of computer vision, in particular to a panoramic camera imaging device and method based on multi-GPU high-speed interconnection. Background technique [0002] The acquisition of panoramic images and panoramic videos is one of the important problems in computer vision. A narrow panorama refers to a panorama that can cover a 360°×180° field of view space, while a panorama image in practical applications refers to various panoramas that exceed the normal viewing angle of human eyes (horizontal 90°, vertical 70°). A wide-view image that covers a large area of ​​the scene. Typical panoramas in the application include: plane panoramas, cylindrical panoramas, spherical panoramas, and polyhedral panoramas. Panoramic video consists of continuous panorama sequences, and panoramic video allows us to obtain dynamic panoramic information in real time. [0003] Panoramic images and panoramic videos have important applications in...
