… We introduce GFrames, a novel local reference frame (LRF) construction for 3D meshes
and point clouds. GFrames are based on the computation of the intrinsic gradient of a scalar …

The goal of this review paper is to recall the concept of geodetic reference frame, showing
its intrinsic dependence from all the information and choices related to its realization, and to …

… FPi,n, for each of them we compute the local reference frame at the corresponding points
according to the method under evaluation, so as to come up with the local reference frame pair …

… of survey knowledge, local reference frames played an important role: Participants performed
better when their body or pointing targets were aligned with the local reference frame (…

… Abstract—The local reference frame (LRF), as an independent … These descriptors are
either based on local reference frame (LRF) or not. An LRF, as illustrated in Fig. 1(a), is an …

… These experimental results show that a local reference frame is mostly more pertinent to
robot localization. The uncertainty for robot position is smaller whenever the robot is locally …

Local reference frames (LRFs) have been widely used for 3D local surface description. In this
work, we propose a repeatable LRF with strong robustness to different nuisances. Different …

… A logical approach to the problem is to develop a Local Reference Frame (LRF) which is
fixed to the crust within a defined polygon, and which is also directly traceable to GNSS …

… leads to the proposed local reference frame technique. … In order to compare the local reference
frame technique to a … with the local reference frame system noise error of Fig. 2, shown in …

Objective The conventional reference frame for the femur has limited relevance for the
planning of hip surgery as the femoral neck axis, a crucial reference for surgeons, has to be …
