|Absolute pose estimation using 3D-2D line correspondences and vertical direction|
Pose estimation is a fundamental building block of various vision applications, e.g. visual
odometry, image-based localization and navigation, fusion, and augmented reality.
Herein, we are interested in absolute pose estimation with line correspondences, which consists in determining the position and orientation of a camera with respect to a 3D world coordinate frame.
|Collaborative Mobile Image Processing Demo Application|
Reconstruction of the surrounding 3D world is of particular interest either for mapping, civil applications or for entertainment. We proposed a pipeline that utilizes an ad-hoc network of camera equipped smartphones in a collaborative manner. Data, computations and results can be shared among the participant devices without centralization. The reconstruction is based on segmented planar regions which is especially suitable for scenes having large (near) planar parts. Once the calibration parameters are known, the perspective distortion of a planar region in two views makes it possible to compute the normal and distance of the region w.r.t the world coordinate system.
