Studying the geometric distribution of the light field in terms of absolute radiometry required expensive and complex instruments. New types of compact 360-degree cameras have recently appeared on the consumer technology market. Some of these allow users to access raw imagery, offering sensor-level data that can be directly exploited for absolute light quantification. This paves the way for easy-to-use, inexpensive and accessible radiance cameras that can be operated in a wide range of natural environments. This dataset presents raw format images captured with the camera Insta360 ONE for its calibration and characterization. These experiments include geometric calibration, relative illumination evaluation, spectral response determination, absolute spectral radiance calibration, as well as linearity and dark frame analysis. In addition, we are providing data from a calibration validation experiment based on co-located measurements of the sky's downward radiance using a 360-degree calibrated camera and a ... : This research was supported by the SMAART program through the Collaborative Research and Training Experience program (CREATE) of the Natural Sciences and Engineering Council of Canada (NSERC), the Sentinel North program of Université Laval, made possible, in part, thanks to the funding from the Canada First Research Excellence Fund, the Canadian Excellence Research Chair on Remote sensing of Canada's new Arctic frontier, and Marcel Babin Discovery Grant #RGPIN-2020-06384. ...
