Abstract:
Provided is a camera pose estimation apparatus that estimates an initial camera pose using one of an input depth image and an input color image, and refines the initial camera pose using the other image. When the initial camera pose is estimated using the input depth image, the radius of a first area, in which color information is matched for refinement, can be adaptively set according to the distribution of the depth value of at least one first point that is subject to matching.
Abstract:
Provided is a method of modeling a target object, the method including obtaining information about the target object including an arrangement of particles including target particles, generating coarse particles by down-sampling the target particles, modeling a movement of the target object based on the coarse particles, and redefining the target particles based on a result of the modeling.
Abstract:
Provided are a method and a corresponding apparatus for modeling a deformable body including particles that define a strain energy generated by an external force with respect to a deformable body including particles, and control a displacement of the deformable body based on a volume of the particles corresponding to the displacement of the deformable body, where the displacement is determined based on the strain energy.
Abstract:
A system, apparatus, and method for precisely estimating a three-dimensional (3D) position and a direction. The 3D position and direction estimation apparatus may estimate a distance between at least one receiver and at least one transmitter and a direction of a remote device, based on intensity information of a signal measured at the at least one receiver, may sequentially select the minimum number of intensity information for estimating the 3D position and the direction of the remote device, in a descending order of robustness against noise, based on the estimated distance and direction of the remote device, and may precisely estimate the 3D position and the direction of the remote device based on the selected intensity information.
