Angular Calibration of Visible and Infrared Binocular All-Sky-View Cameras Using Sun Positions

Calibration of uncooled thermal infrared cameras

The calibration of uncooled thermal infrared (IR) cameras to absolute temperature measurement is a time-consuming, complicated process that significantly influences the cost of an IR camera. Temperaturemeasuring IR cameras display a temperature value for each pixel in the thermal image. Calibration is used to calculate a temperature-proportional output signal (IR or thermal image) from the meas...

Calibration of Parallel Multi-View Cameras

This paper focuses on the calibration problem of a multi-view shooting system designed for the production of 3D content for auto-stereoscopic visualization. The considered multiview camera is characterized by coplanar and decentered image sensors regarding to the corresponding optical axis. Based on the Faugéras and Toscani’s calibration approach, a calibration method is herein proposed for the...

Self-Calibration of Central Cameras by Minimizing Angular Error

Mid-infrared all-sky survey with AKARI

AKARI (formerly called ASTRO-F) is the first Japanese astronomical infrared satellite and it is now in a sun-synchronous polar orbit at the altitude of 700 km. One of the major programs of AKARI observations is an all-sky survey in the midto far-infrared spectral region with 6 photometric bands. AKARI has a 685mm telescope, which is cooled down to about 6K by superfluid liquid helium and mechan...

Robust Pedestrian Detection by Combining Visible and Thermal Infrared Cameras

With the development of intelligent surveillance systems, the need for accurate detection of pedestrians by cameras has increased. However, most of the previous studies use a single camera system, either a visible light or thermal camera, and their performances are affected by various factors such as shadow, illumination change, occlusion, and higher background temperatures. To overcome these p...
