1 Stereographic Analysis of Coronal Features for the STEREO Mission Eric De Jong, Paulett Liewer, Jeff Hall, Jean Lorre, Shigeru Suzuki and the SECCHI Team STEREO Science Working Group,Berkley California Outline STEREO analysis using triangulation Progress on Automatic Feature Tracking Test stereo loops and their 3D reconstruction Coronal EUV loop feature tracking Coronal Mass Ejection (CME) tracking

2 Determination of 3D Structure via Triangulation

3 Tiepointing Tools for Triangulation of Solar Features Tiepointing by Hand & Eye Use commercial software (ENVI) on conventional workstation Use 3D Cursor Tiepointing Tool (developed at JPL) –Needs workstation supporting stereo viewing Tools tested using synthetic stereo image pairs Tiepointing tools to locate the same “feature” in both images Present Research: Automatic Tiepointing using Automatic Feature Tracking Feature tracking for loops - test loops and real data Feature tracking for CMEs - real data

6 Automatic Feature Tracking for Coronal Loops as seen in EUV and Soft X-ray A. Test Loops - Case 1 of 2 SUN: 16May1994 CML=140  SUN: 17May1994 CML=125  * Pattern on sphere shows magnetic field at photosphere (magnetogram) Original Stereo Data - 2 Views of 3D Coronal Loops (angle=15º) Loops computed from measured solar magnetic fields at photosphere*

7 Results for Automatic Stereo Feature Tiepointing Algorithm: Follow along bright features Dark Segments on Loops are Matched Stereo Points* SUN: CML=125  SUN: CML=140  * Matched Stereo Points: Rays from the two points cross near the Sun

8 Comparison of Reconstructed 3D Loops with Original 3D loops reconstructured from tiepoints shown as colored loops overlying original black loops Successful Automatic 3D reconstruction of loops from stereo pair using automatic tiepointing and XYZSUN

9 Automatic Feature Tracking for Coronal Loops as seen in EUV and Soft X-ray A. Test Loops - Case 2 * Pattern on sphere shows magnetic field at photosphere (magnetogram) Original Stereo Data - 2 Views of 3D Coronal Loops (angle=26º) Loops computed from measured solar magnetic fields at photosphere* SUN: 3January1994 CML=96  SUN: 5January1994 CML=70 

11 Comparison of Reconstructed 3D Loops with Original Too many loops leads to false tiepoints Rays from different loops in the two images happen to cross near SUN 3D loops reconstructured from tiepoints shown as colored loops overlying original black loops

22 Zareh Gorjian combines a 3D terrain model, constructed from FIDO “Pancam” field test images, with Dan Maas’ rover model to create this simulated view of MER desert operations. One work year was required to produce this 36 x Cluster Computing Mosaic Generation speed-up. A significant “Virtual Rover” challenge is to automate the speed-up and control of similar processes to achieve real-time performance. Zooming in on the MER instruments enables us to see the level of detail available in a single photorealistic digital high resolution image.
