Camera calibration is a two-step process where first a linear algebraic approximation is followed by a nonlinear minimization. The nonlinear minimization adjusts the pin-hole and lens distortion models to the calibrating ...

[EN] 3D object alignment is essential in multiple fields. For instance, to allow precise measurements in metrology, to perform surface/volumetric checks or quality control in industrial inspection, to align partial captures ...

[EN] Human plays a key role in metaverse and digital twin systems and thus live three-dimensional (3D) human shape reconstruction brings significant improvement for highly accurate anthropomorphic measurements. However, ...

Image processing in photogrammetry is commonly used for scene reconstruction. Although two-dimensional applications can be solved using isolated images, reconstruction of three-dimensional scenes usually requires the use ...

[ES] El sector de la automoción se encuentra inmerso en un continuo estado de cambio a nivel mundial. Las economias globales, la fuerte competencia y los mercados emergentes obligan a replantearse continuamente los objetivos ...

[EN] Mixed reality (MR) in standalone headsets has many advantages over other types of devices. With the recent appearance of the Passthrough of Oculus Quest 2, new possibilities open up. This work details the features of ...

In auto-guidance of agricultural vehicles in cultivated stubble fields, a precise measurement of the vehicle's lateral offset could help achieve improved navigation accuracy. This paper presents an automated method for ...

This study proposes the concept of bodyprints to perform re-identification of people in surveillance videos. Bodyprints are obtained using calibrated depth-colour cameras such as kinect. The author's results on a database ...
