This letter presents a novel on-line path planning method that enables aerial robots to interact with surfaces. We present solution the problem of finding trajectories drive robot towards surface and move along it. Triangular meshes are used as map representation is free fixed discretization allows for very large workspaces. propose leverage planar parametrization methods obtain lower-dimension...

Modeling and simulation of disease spreading in pedestrian crowds have recently become a topic increasing relevance. In this paper, we consider the influence crowd motion complex dynamical environment on course infection pedestrians. To model dynamics, kinetic equation for multi-group flow based social force coupled with an Eikonal equation. This is non-local SEIS contagion spread, where beside...

In this paper, we propose and analyze mesh-based tools to control bounding motions of an 8 degree-of-freedom planar quadruped model with limited footholds on terrain. There are two complementary goals in our presentation. First, we aim to clarify potential advantages and diadvantages of our mesh-based approach in planning agile motions for a legged system. A key advantage is the ability to map ...

We present an algorithm to generate a one-sided approximation of a given triangular mesh. We refer to such an approximate mesh as a bounding mesh, which includes the original mesh and has fewer vertices. Likewise, an inner bounding mesh is defined as an approximate mesh that is included by a given mesh. Our proposed bounding mesh algorithm performs iterative edge contractions and can generate b...

This article presents a method for crop row structure characterization that is adapted to phenotyping-related issues. In the proposed method, a crop row 3D model is built and serves as a basis for retrieving plant structural parameters. This model is computed using Structure from Motion with RGB images acquired by translating a single camera along the row. Then, to estimate plant height and lea...

This article describes a process to include in a volumetric model various anatomical and mechanical information provided by different sources. Three stages are described, namely a mesh construction, the non-rigid deformation of the tetrahedral mesh into various volumetric images, and the rasterization procedure allowing the transfer of properties from a voxel grid to a tetrahedral mesh. The met...

We present a multi-view stereo reconstruction technique that directly produces a complete high-fidelity head model with consistent facial mesh topology. While existing techniques decouple shape estimation and facial tracking, our framework jointly optimizes for stereo constraints and consistent mesh parameterization. Our method is therefore free from drift and fully parallelizable for dynamic f...

This paper extends the hierarchical radiosity method to environments in which geometry and surface attributes can be changed dynamically. New algorithms are presented for maintaining an appropriately-sized mesh and speeding the construction of the corresponding linear system. Mesh folding, the unrefinement of a mesh, is used to optimize mesh size while maintaining a specified error tolerance. T...
