Collect Information
The data set was simulated with a capture date and time of August 12, 2010, 18:00.00 GMT. The imaging system was a simple multi-band framing array featuring an RGB focal plane and a panchromatic band. The focal length of the system was modeled at 125.09mm. The detector was a 1200x800 array with square pixels 32μm in size. The simulated flight path was circular with a fixed stare point in the center of the scene and a nominal declination angle of 40 degrees. The sampling rate was 2Hz and images were captured for 210 seconds, resulting in a 420 image data set.
Each radiance image is accompanied by a truth image produced by DIRSIG. Information such as the minimum and maximum range, (X,Y,Z) hit coordinates and normals for the minimum and maximum range, and material IDs for the minimum and maximum range are available.
Data
Processed data
In addition to the DIRSIG data provided above, some processed data has been provided for convenience. The radiance images produced by DIRSIG were used to create RGB and panchromatic 8-bit JPEGs by using a linear 2% scaling. Point clouds generated using the (X,Y,Z) hit coordinates and normals are also available for download; color information in the point clouds comes from the JPEG images.
