MEASURING PHOTOGRAMMETRIC CONTROL TARGETS IN LOW CONTRAST IMAGES

Antonio Maria Garcia Tommaselli

Adilson Berveglieri

{{t.titulosSecciones.eresAutor}}

Abstract: This paper presents an experimental assessment of photogrammetric targets and subpixel location techniques to be used with low contrast images such as images acquired by hyperspectral frame cameras. Eight different target patterns of varying shape, background

DRIVER PREFERENCE CONCERNING IN-CAR ROUTE GUIDANCE AND NAVIGATION SYSTEM MAPS FOR DRIVERS WITH COLOR VISION DEFICIENCY

Renan Furlan de Oliveira

Edmur Azevedo Pugliesi

Ana Paula Marques Ramos

Mônica Modesta Santos Decanini

{{t.titulosSecciones.eresAutor}}

Abstract: In-car Route Guidance and Navigation Systems (RGNS) are used to help drivers navigate. These maps have mainly been designed to accommodate drivers with normal color vision. However, the color perception of people with normal color vision differs from that of

LAND USE AND LAND COVER MAPPING IN DETAILED SCALE: A CASE STUDY IN SANTA ROSA DE LIMA-SC

Rodrigo de Campos Macedo

Abdon Luiz Schmitt Schmitt

Joshua C. Farley

Alfredo Celso Fantini

Ademir Antonio Cazella

Paulo Antonio de Almeida Sinisgalli

{{t.titulosSecciones.eresAutor}}

Abstract: It is challenging to reconcile large scale data with the dynamic characteristics present in land use. Such dynamism requires data with a high repetition of sampling. An alternative is the integration of data of high spatial resolution and low temporal resolut

Fabiano Scheer Hainosz

{{t.titulosSecciones.eresAutor}}

Abstract: Recent developments in LIDAR technology lead to the availability of the waveform systems, which capture and digitize the whole return of the emitted LASER pulse. As many objects may cause multiple returns in the same echo, one task is to detect and separate d
