Next view planning for a combination of passive and active acquisition techniques

TLDR
This work shows an approach to next view planning for a fusion of shape from Silhouette and shape from structured light as an example of an active 3D reconstruction technique in order to get 3D shape reconstruction with minimal different views.
Abstract
In order to create a complete three-dimensional model of an object based on its two-dimensional images, the images have to be acquired from different views. An increasing number of views generally improves the accuracy of the final 3D model but it also increases the time needed to build the model. The number of the possible views can theoretically be infinite. Therefore, it makes sense to try to reduce the number of views to a minimum while preserving a certain accuracy of the model, especially in applications for which the performance is an important issue. We show an approach to next view planning for a fusion of shape from Silhouette, as an example of a passive 3D reconstruction technique, and shape from structured light, as an example of an active 3D reconstruction technique in order to get 3D shape reconstruction with minimal different views. Results of the algorithm developed are presented for both synthetic and real input images.

Next best view planning for active model improvement

TL;DR: The proposed method deploys a hierarchical uncertainty driven model refinement process designed to select vantage viewpoints based on the model’s covariance structure and appearance, as well as the camera characteristics, to determine the Next Best View (NBV).

Developing visual sensing strategies through next best view planning

TL;DR: An incremental approach is developed, which alternates between an accuracy-driven next best view determination and recursive path planning, and a novel cost function that quantifies the expected contribution of future viewing configurations.

Image selection for improved Multi-View Stereo

TL;DR: This paper proposes an image selection scheme for multi-view stereo which results in improved reconstruction quality compared to uniformly distributed views and is based on the idea of incrementally selecting images so that the overall coverage of a simultaneously generated proxy is guaranteed without adding too much redundant information.

Rapid octree construction from image sequences

TL;DR: A new algorithm for computing the octree bounding volume from multiple silhouettes is developed and applied to an object rotating on a turntable in front of a stationary camera, which requires less total computation than previous algorithms, runs in close to real-time, and builds a model whose resolution improves over time.
