| description | The SkySat-1 satellite lauched by Skybox Imaging on November 21 in 2013 opens a new chapter in civilian earth observation as it is
the first civilian satellite to image a target in high definition panchromatic video for up to 90 seconds. The small satellite with a mass of
100 kg carries a telescope with 3 frame sensors. Two products are available: Panchromatic video with a resolution of around 1 meter
and a frame size of 2560 × 1080 pixels at 30 frames per second. Additionally, the satellite can collect still imagery with a swath of 8 km
in the panchromatic band, and multispectral images with 4 bands. Using super-resolution techniques, sub-meter accuracy is reached
for the still imagery. The paper provides an overview of the satellite design and imaging products. The still imagery product consists
of 3 stripes of frame images with a footprint of approximately 2.6 × 1.1 km. Using bundle block adjustment, the frames are registered,
and their accuracy is evaluated. Image quality of the panchromatic, multispectral and pansharpened products are evaluated. The video
product used in this evaluation consists of a 60 second gazing acquisition of Las Vegas. A DSM is generated by dense stereo matching.
Multiple techniques such as pairwise matching or multi image matching are used and compared. As no ground truth height reference
model is availble to the authors, comparisons on flat surface and compare differently matched DSMs are performed. Additionally,
visual inspection of DSM and DSM profiles show a detailed reconstruction of small features and large skyscrapers. |
