Method for synthesizing stereoscopic image with long focal length and stereoscopic imaging system

Abstract

The invention provides a method for synthesizing a stereoscopic image with a long focal length and a stereoscopic imaging system. The method comprises the following steps of: firstly, adjusting the focal length of a zoom lens to a first focal length; respectively shooting a first image and a second image by using the zoom lens and a prime lens; secondly, adjusting the focal length of the zoom lens to a second focal length; shooting a third image by using the zoom lens; thirdly, positioning a region of the third image which occupies the first image, according to the magnification factor of the second focal length relative to the first focal length; calculating a first disparity map positioned between the first image and the second image in the region; magnifying the first aberration map into a second disparity map according to the magnification factor; and finally, synthesizing a fourth image of the prime lens, which is positioned at the second focal length, by using the third image and the second disparity map and outputting the third image and the fourth image to be as stereoscopic images.

Description

technical field [0001] The present invention relates to an image generation method and system, and in particular to a method for synthesizing a long focal length stereoscopic image and a stereoscopic imaging system. Background technique [0002] The stereo camera is composed of double lenses with the same specifications, and the distance between the two lenses is about 7.7 cm to simulate the actual distance between human eyes. The focal length, aperture, shutter and other parameters of the dual-lens are controlled by the processor of the stereo camera, and through the trigger of the shutter cable, images of the same area but with different perspectives can be shot. This image is used to simulate human left and right eye image. [0003] The left and right eye images captured by the stereo camera are displayed alternately through the display device at a frequency exceeding the persistence of human vision, and with the switching of the liquid crystal shutter glasses worn on th...

Problems solved by technology

[0005] However, because the stereo camera has to use the left and right lenses of the same focal length to capture the image of the same scene at the same time, the captured image has a stereoscopic effect, so the above-mentioned simplified stereo camera can only shoot a stereoscopic image at a specific focal length

When the user lengthens the zoom lens, only the main lens can capture a zoomed-in image, and the auxiliary lens can still capture a wide-angle image. This will make the content of the two images captured by the stereo camera inconsistent, making it impossible to synthesize a stereo image
