Method for extracting a three-dimensional model using appearance- based constrained structure from motion

摘要

In a computerized method, a three-dimensional model is extracted from a sequence of images that includes a reference image. Each image in the sequence is registered with the reference image to determine image features. The image features are used to recover structure and motion parameters using geometric constraints in the form of a wireframe mode. A predicted appearance is generated for each image using the recovered structure and motion parameters, and each predicted appearance is registered with the corresponding image. The recovering, generating, and registering steps are repeated until the average pixel value difference (color or intensity) between the predicted appearances and the corresponding images is less than a predetermined threshold.
