Single-sensor paralleling type stereoscopic picture shooting method and device

Abstract

The invention discloses a single sensor parallelly-arranged type stereoscopic image photographing method and apparatus, belonging to the stereoscopic image photographing technology, the method comprises steps that: (1) the scenery light ray can be focused by two sets of optical imaging lens arrays; (2) two ways of optical signals are respectively reflected by a first reflection mirror and a second reflection mirror; (3) two sets of optical signals respectively pass through the direction conversion components; (4) two sets of optical signals are imaged on the sensor in parallel; (5) an image signal of sensor is stored by image processing. The apparatus comprises a sensor arranged at the direction with 90 degrees comparing to a normal mounting position for 4:3 general format; two sets of optical imaging lens arrays with axial line distance of 25-100 mm are arranged at the front of the sensor, two ways of optical signals are projected on left and right sides of the sensor to image by the optical imaging lens arrays, the first reflection mirror, the second reflection mirror and the light path direction conversion components. The invention has advantages that the structure is simple and the consistency of the left and the right images composing the stereoscopic image is good.

Description

technical field [0001] The present invention relates to stereoscopic image capturing technology, more specifically, it relates to a single-sensor parallel stereoscopic image capturing method, and the present invention also relates to a stereoscopic image capturing device for realizing the above method. Background technique [0002] The human eye can produce a stereoscopic perception of the scene according to the visual difference between the left and right eyes, so the general stereo camera equipment uses dual camera lenses to image the scene and then process it. However, the problems caused by this are very prominent: mainly reflected in 1. The focusing performance of the two lenses cannot be completely consistent, which may cause differences in the definition of the left and right video images, and finally lead to blurred image formation. 2. The installation of the dual lens cannot ensure that the images are consistent in alignment, resulting in the inability to ensure the...

Problems solved by technology

However, the problems brought about by this are very prominent: mainly reflected in 1. The focusing performance of the two lenses cannot be completely consistent, which may cause the definition of the left and right video images to be different, and finally cause the image to be blurred

2. The installation of the double lens cannot guarantee the consistency of the image alignment, resulting in the inability to ensure the horizontal and tilt consistency of the image in terms of viewing angle. At that time, the two images will deviate when the three-dimensional overlap occurs, and the image will produce blurred overlap

3. Differences in the consistency of the dual image sensors lead to inconsistencies in image brightness, contrast, chromaticity, and gray scale, and there are obvious visual differences between the left and right images. When the images overlap three-dimensionally, visual dizziness and image blurring will occur.
