Combining Edge and One-Point RANSAC Algorithm to Estimate Visual Odometry
(2013-07-28)
In recent years, classical structure from motion based SLAM has achieved significant results. Omnidirectional camera-based motion estimation has become interested researchers due to the lager field of view. This paper ...
Extraction of building roof planes with stratified random sample consensus
(2018-09-01)
This paper describes a consensus-set estimation for building roof-plane detection using a stratified random sample consensus (sRANSAC) algorithm applied to point clouds acquired by laser scanning systems. The main idea is ...

Aplicação de técnicas de processamento e análise de imagens para detecção de edificações e vegetação a partir de dados LiDAR
(Universidade Estadual Paulista (Unesp), 2016-02-16)
As nuvens de pontos provindas de Sistemas de Varredura a LASER (Light Amplification by Stimulated Emission of Radiation) Aerotransportados (SVLA) representam a superfície com um grande detalhamento, sendo registrada a ...
Construcción de mosaicos de imágenes
(Universidad Michoacana de San Nicolás de Hidalgo, 2007-06)
When it is needed to cover wide angles in the apprehension of a scene or it is necessary digitize big panoramas, the limitation in the visual field of a camera and his lens they do not provide the whole field of vision ...
3D motion estimation based on pitch and azimuth from respective camera and laser rangefinder sensing
(11/03/2013)
This paper proposes a new method to estimate the 3D motion of a vehicle based on car-like structured motion model using an omnidirectional camera and a laser rangefinder. In recent years, motion estimation using vision ...
Altimetria por satélite radar na medição do nível d'água de rios de pequeno e médio porte: um estudo de caso no Rio São Francisco
(Universidade Federal de Minas GeraisUFMG, 2018-04-23)
Although radar altimetry is used primarily to study ocean topography and monitoring of the ice caps, the amount of data available favours its use in continental hydrology studies. Satellite altimetry radar can contribute ...
Detecção de mudanças e recuperação de forma em mapas 3D basedos em nuvens de pontos
(Universidade Federal de Minas GeraisUFMG, 2009-12-21)
This work proposes a framework to efficiently detect and segment changes in 3D point clouds. Initially, we simplify the point cloud which generates a tree representation in order to preserve the relevant characteristics ...
Uma abordagem otimizada para reconhecimento de logomarcas de veículos usando SURF
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência da Computação - PPGCCCâmpus São Carlos, 2015-12-09)
Perform fast and accurate recognition of objects is still a challenging task in many
applications. In this sense the techniques based on detection and description of image features and in correspondence (matching) has ...
