Stereo camera
The present invention relates to a stereo camera which includes: a main camera which photographs a first image; a sub-camera which has camera parameters different from those of the main camera and photographs a second image; a distance information acquiring part which associates each pixel in the first and second images and acquires distance information including parallax information; and a right/left image generating part which generates a stereo view image based on one of the first and second images and the distance information.
1. A stereo camera, comprising:
a first imaging part which photographs a first image;
a second imaging part which has camera parameters different from those of said first imaging part and photographs a second image;
a distance information acquiring part which associates each pixel in said first and second images and acquires distance information including parallax information, wherein said distance information acquiring part decides a correspondence detection area based on photographing information at the time of photographing said first and second images, and
a right/left image generating part which generates a stereo view image based on one of said first and second images and said distance information, wherein said first imaging part has a higher resolution than said second imaging part, and said right/left image generating part regards said first image as a main image, displaces an image in said correspondence detection area inside said second image in accordance with said parallax information, and regards said first image and said new second image as said right/left images.
2. The stereo camera according to claim 1 , wherein, when a number of pixels inside said correspondence detection area of said second image is smaller than a number of pixels inside a correspondence detection area of said first image, said right/left image generating part compensates pixel information from said first image.
3. A stereo camera, comprising:
a first imaging part which photographs a first image;
a second imaging part which has camera parameters different from those of said first imaging part and photographs a second image;
a distance information acquiring part which associates each pixel in said first and second images and acquires distance information including parallax information, wherein said distance information acquiring part decides a correspondence detection area based on photographing information at the time of photographing said first and second images, and
a right/left image generating part which generates a stereo view image based on one of said first and second images and said distance information, wherein said first imaging part has a higher resolution than said second imaging part, and when said second image has a higher photographing magnification than said first image, said right/left image generating part embeds said second image into said first image to generate a new second image, and regards said first image and said new second image as said right/left images.
4. A stereo camera, comprising:
a first imaging part which photographs a first image;
a second imaging part which has camera parameters different from those of said first imaging part and photographs a second image;
a distance information acquiring part which associates each pixel in said first and second images and acquires distance information including parallax information, wherein said distance information acquiring part decides a correspondence detection area based on photographing information at the time of photographing said first and second images, and
a right/left image generating part which generates a stereo view image based on one of said first and second images and said distance information, wherein said first imaging part has a higher resolution than said second imaging part, and when said first image has a higher photographing magnification than said second image, said right/left image generating part embeds said first image into said second image to generate a new first image, and regards said new first image and said second image as said right/left images.
5. A stereo camera, comprising:
a first imaging part which photographs a first image;
a second imaging part which has camera parameters different from those of said first imaging part and photographs a second image;
a distance information acquiring part which associates each pixel in said first and second images and acquires distance information including parallax information; and
a right/left image generating part which generates a stereo view image based on one of said first and second images and said distance information,
wherein said first imaging part has a higher resolution than said second imaging part, said stereo camera further comprises a sensor which senses arrangement of said stereo camera with said first and second imaging parts arrayed in a horizontally placed manner in parallel with a horizontal plane, and stops an operation of said distance information acquiring part in the case of sensing horizontal placement, and said right/left image generating part provides information of said first image to said second image to create a new second image, and regards said first image and said new second image as said right/left images.
