• Error_evaluation

Describe Error_evaluation here.

Here are a list of error evaluation tools and ideas

• formal uncertainty -- standard, bottom of the RESIDUALS.TXT. Contains the fit of all the landmarks and overlaps.
• Best 80% of landmarks. Taken from ?
• CompareOBJ
• CompareOBJ TR
• CompareOBJ --save-plate-error error
• diffShape and gnuplot delta.gpi
• SIGMAS.TXT plotted with sig.gpi
• 2D heat map plot of number of images in landmarks
• 2D heat map plot of residual errors for landmark
• 2D heat map plot of residual errors for images
• Evaluation of delta between truth S/C position and solved for S/C position: as an RMS
• 2D plot of delta between truth S/C position and solved for S/C position.

• Number of "issues" (or >>) in MAPINFO, PICINFO and RESIDUALS.TXT

To Do

• Rebuild shape 3.7
• Get RMS for each ZMAP

• Run PreSurvey CompareOBJ

RESIDUALS

• img x, y val val overlap x, y val val img x, y val val
  • The 1st column is a list of 1. IMAGEFILES included in the landmark 2. overlaps with other landmarks 3. Limbs
  • The 2nd column is the error in deltaX (# pixels in image resolution)
  • The 3rd column is the error in deltaY (# pixels in image resolution)
  • The 4th column is the magnitude of the error (combines deltaX and deltaY)
  • The 5th column is the error in physical units (km)

......................... name val

MAPINFO.TXT name ........ val val

• col 9 formal uncertainty in meters of the landmark position
• col 10 Flag

• ">>" Flag showing landmarks that are below the pixel threshold. You might want to look at.

• "**" Fewer than 3 images
• col 11 Residual in meters of the nominals and position

PICINFO.TXT name ....... val dx, dy, dz dCx, dCy, dCz

• Col 7 - Pixel residual (RMS in pixels)
