A backpack-mounted omnidirectional camera with off-the-shelf navigation sensors for mobile terrestrial mapping: Development and forest application
(2018-03-09)
The use of Personal Mobile Terrestrial System (PMTS) has increased considerably for mobile mapping applications because these systems offer dynamic data acquisition with ground perspective in places where the use of wheeled ...
Calibration of a catadioptric omnidirectional vision system with conic mirror
(2016-03-01)
Omnidirectional vision systems that enable 360° imaging have been widely used in several research areas, including close-range photogrammetry, which allows the accurate 3D measurement of objects. To achieve accurate results ...
A Fisheye image matching method boosted by recursive search space for close range photogrammetry
(2019-06-01)
Close range photogrammetry (CRP) with large field-of-view images has become widespread in recent years, especially in terrestrial mobile mapping systems (TMMS). However, feature-based matching (FBM) with omnidirectional ...

(Ieee, 2020-01-01)
This paper presents a feasibility study on the use of omnidirectional systems for 3D modelling of agricultural crops, aiming a systematic monitoring. Omnidirectional systems with multiple sensors have been widely used in ...
Semantic Mapping with Omnidirectional Vision
(IEEE COMPUTER SOC, 2018-01-01)
This paper presents a purely visual semantic mapping framework using omnidirectional images. The approach rests upon the robust segmentation of the robot's local free space, replacing conventional range sensors for the ...
A monocular wide-field vision system for geolocation with uncertainties in urban scenes
(IOP Publishing, 2020-06-22)
In engineering applications related to video surveillance, the use of monocular omnidirectional cameras would reduce costs and complications associated with infrastructure, installation, synchronization, maintenance and ...
Geometric model and assessment of a dual-fisheye imaging system
(2018-06-01)
This paper presents a technique for the calibration of a 360° dual imaging system (Ricoh Theta S) composed of two cameras with fisheye lenses specially mounted in a common structure. The experiments are based on calibration ...
Platform calibration of an omnidirectional vision system composed of a camera and a conical mirrorCalibração da Plataforma de um Sistema de Visão Omnidirecional composto por uma Câmara e um Espelho Cônico
(2020-06-30)
Omnidirectional vision systems allow for a 360° imaging field and are applied in many areas of knowledge, including close range Photogrammetry. Obtaining reliable measurements, the Photogrammetry's goal, requires calibration ...
A portable mobile terrestrial system with omnidirectional camera for close range applications
(Universidade Estadual Paulista (Unesp), 2019-03-13)
This research proposes a new technique for close-range mobile data acquisition and processing, consisting of a backpacked light-weight low-cost system. This system integrates an omnidirectional camera and a GPS/IMU system ...
