That sounds interesting. Any links to further explain what DTAM is/how it works?

- severine 7y agoDTAM: Dense tracking and mapping in real-time > DTAM is a system for real-time camera tracking and reconstruction which relies not on feature extraction but dense, every pixel methods. As a single hand-held RGB camera flies over a static scene, we estimate detailed textured depth maps at selected keyframes to produce a surface patchwork with millions of vertices. We use the hundreds of images available in a video stream to improve the quality of a simple photometric data term, and minimise a global spatially regularised energy functional in a novel non-convex optimisation framework. Interleaved, we track the camera's 6DOF motion precisely by frame-rate whole image alignment against the entire dense model. Our algorithms are highly parallelisable throughout and DTAM achieves real-time performance using current commodity GPU hardware. We demonstrate that a dense model permits superior tracking performance under rapid motion compared to a state of the art method using features; and also show the additional usefulness of the dense model for real-time scene interaction in a physics-enhanced augmented reality application. https://ieeexplore.ieee.org/document/6126513 https://ieeexplore.ieee.org/document/6126513
- saganus 7y agoAwesome, thanks!
- gauku 7y agoI found this post summarizes the concepts step by step and is really helpful. http://ahumaninmachinesworld.blogspot.com/2015/07/dtam-dense-tracking-and-mapping.html http://ahumaninmachinesworld.blogspot.com/2015/07/dtam-dense...
