System and method for stereoscopic photography

摘要

A stereoscopic photography is provided, which includes a first image sensor, a second image sensor, a synchronization module, a combination module, a calibration module, and a stereo matching module. The first image sensor is utilized to capture a first image. The second image sensor is utilized to capture a second image. The calibration module is utilized to perform an image calibration and a horizontal rectification for the first image and the second image. The stereo matching module is utilized to calculate a distance difference between a reference pixel of the first image and a corresponding pixel of the second image. The stereo matching module compares costs of multiple pixels relative to the reference pixel in a pixel row of the second image in an interval manner. A method for performing stereoscopic photography and a stereo matching method are also provided.

1. A stereoscopic photography system, comprising:
a first image sensor utilized to capture a first image for generating a first data stream; a second image sensor disposed apart from the first image sensor by a horizontal distance, utilized to capture a second image for generating a second data stream; a synchronization module electrically coupled to the first image sensor and second image sensor, utilized to synchronize the first data stream and the second data stream and utilized to synchronize auto-exposure and auto-white balance parameters of the first image sensor and the second image sensor; a combination module utilized to combine the first data stream and the second data stream for outputting a combined image data which comprises the first image and the second image; a calibration module utilized to perform an image calibration and a horizontal rectification for the first image and the second image in the combined image data; and a stereo matching module comprising a sub-pixel interpolation unit which is utilized to calculate a distance difference between a reference pixel of the first image and a corresponding pixel of the second image, wherein the stereo matching module compares costs of a plurality of pixels relative to the reference pixel in a pixel row of the second image in an interval manner and an error of the distance differences is less than 0.1 pixels.
