Problems solved by technology

In terms of video surveillance at traffic intersections, traditional catadioptric panoramic images cannot obtain clear images of traffic conditions, which leads to the thinking of solving the clarity of panoramic images
The traditional image acquisition method can no longer meet the requirements for information accuracy and information breadth brought about by the development of science and technology, and the catadioptric panoramic vision cannot acquire external environmental information adaptive zoom, which hinders the development of panoramic vision
Improving the clarity of panoramic vision images and realizing adaptive zoom panoramic images is a major challenge at present

Embodiment Construction

[0036] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0037] The invention implements a high-speed rotation self-adaptive panorama imaging system by applying image splicing and image fusion technologies.

[0038] The device of the invention provides an omnidirectional camera device with rotation. It mainly includes scientific grade CMOS camera[1], pan / tilt[2], fixed base[3], auto-focus lens[5], and high-speed image processing computer[6].

[0039] The implementation method of the present invention is shown in the accompanying drawings: acquire n images of a scene, preprocess the n images, and calculate the rotation angle of two adjacent images according to the specific parameters of the camera and the rotation angle of the single image taken by the camera. Roughly coincident area. Determine the main perspective image i of n images, apply the surf algorithm in the overlapping area, extract the feature points of two adj...

Abstract

The present invention disclosed a high -speed rotating focal length self -adaptive panoramic imaging method.Including the following steps, step 1: The camera rotates a circle for a cycle, obtains the image taken by the camera of the current rotation cycle; Step 2: Blogging the image; step 3: splicing and fusion of images; step 4: Change the cameraPerspective, do the next cycle, repeat step -to -step 4 to get panoramic images.The present invention solves the technical problem of insufficient definition of reflected and reflecting the panoramic image, and effectively eliminates the effects of traditional reflected panoramic visual image distortion.

Description

technical field [0001] The invention belongs to the field of machine vision, and in particular relates to a high-speed rotational focal length self-adaptive panoramic imaging method for obtaining high-definition panoramic images. Background technique [0002] Panoramic vision can perceive and obtain powerful advantages of up to 360° visual information, making panoramic vision widely used in many fields. [0003] Civilian field: As an important means of obtaining environmental information, panoramic vision has been widely used in distance education, virtual reality and video surveillance at traffic intersections. In terms of video surveillance at traffic intersections, traditional catadioptric panoramic images cannot obtain clear images of traffic conditions, which leads to the thinking of solving the clarity of panoramic images. Traditional image acquisition methods can no longer meet the requirements for information accuracy and information breadth brought about by the dev...
