Stereoscopic Imaging From Mobile Platform Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing photographic stereoscopy and LADAR imaging techniques are limited by restricted viewing angles, requirement for similar image sizes, complexity in evaluating effectiveness, absence of non-topographic surface texture, and limited use of LADAR technology, which restricts the generation of stereoscopic images.
Innovation Solution
A method and system for obtaining and processing stereoscopic images by resizing and rotating images taken at different times from a mobile platform, allowing for the creation of stereo pairs or anaglyphs, enabling viewing with a stereo pair or anaglyph viewing component, even when images are of different sizes and taken at changing distances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If images are taken at different distances from the scene, then more flexible imaging scenarios are enabled, but the image sizes become different requiring additional processing
Solution Approach 1:
The patent applies parameter changes by systematically adjusting image size through scaling operations. Images captured at different distances are resized to a common dimension using interpolation algorithms, transforming the variable parameter of image size into a uniform parameter that enables straightforward stereo pair formation without complicating the overall system architecture.
2Area of stationary object
If images are captured at different angles, then broader scene coverage is achieved, but the images must be rotated to form proper stereo pairs
Solution Approach 1:
The patent applies preliminary action by performing rotation and alignment operations on images before they are combined into stereo pairs. By pre-rotating images to the correct orientation and pre-aligning them to a common coordinate system, the system prepares the images in advance for seamless integration, reducing the complexity of the final stereo pair formation process.
3Device complexity
If a single camera is used on a mobile platform, then system simplicity is maintained, but platform movement causes image distortion
Solution Approach 1:
The patent applies feedback by incorporating sensors that detect platform movement (pitch, roll, yaw) and using this information to correct image distortion. The system continuously monitors platform orientation and uses this feedback to apply real-time geometric corrections to the captured images, maintaining image quality despite platform motion while keeping the hardware configuration simple.

AI summary
A method is disclosed for performing stereoscopic imaging. The method may involve obtaining a first image of a scene, at a first time, using a camera disposed on a platform, where the distance between the camera and the scene is changing. The camera may be used to obtain a second image of the scene, at a second time, with one of the first and second images being larger than the other. One of the images that is larger than the other may be resized so that the sizes of the two images are substantially similar. Both of the images may be rotated a predetermined degree so that the images form a stereo pair that may be viewed with a stereoscope viewing component or made into an anaglyph for viewing with an anaglyph viewing component.
