SfM algorithms, which compute 3D coordinates from 2D image correspondences, have some disadvantages.
This paper uses Kinect to establish 3D world and 2D image correspondences and, from them, determine camera pose.
Observe that the measurement vector is composed of the elements of the instantaneous homography matrix, H k, computed from image correspondences.
Integration of data extracted from multiple cameras has been proposed in terms of a fusion at feature level as image correspondences [9] or multi-view histograms [10] among others.
For these visualizations, the registration pipeline was the most crucial part where the deformation fields from CT-to-CT registration were obtained and transported into the PET image correspondences in order to overlay segmented functional uptake of the same animal's different scans within the same spatial domain.
It is shown that the combination of depth and image correspondences from the Kinect can yield a reliable estimate of the location and pose of the camera, though noise from the depth sensor introduces an unpleasant jittering of the rendered view.
In this work we describe the AutoCNet library, written in Python, to support the application of computer vision techniques for n-image correspondence identification in remotely sensed planetary images and subsequent bundle adjustment.
The study of 3D hinge angles allows us to design a 3D discrete rotation and to estimate the rotation between a pair of digital images in correspondence.
By detecting the calibration patterns in both the virtual and the camera image, point correspondences for the two sensors can be obtained with sub-pixel accuracy.
In addition, our algorithm runs in real time since it relies on a closed-form estimate of the camera/robot rotation, and can address the image-feature correspondence problem.
