1st Annual PRI Workshop on Image-Based Modeling and Navigation for Space Applications

• June 6-8 Short Course

Welcome to the 1st Annual RPI Workshop on Image-Based Modeling and Navigation for Space Applications. This is a persistent webpages (will continue to exists after the training) that contains the information you need to get ready and the lesson info.

Goals

• Bring the students to the "SPC Training Level 2" TrainingLevels

  • Provide enough SPC hand-on skills that basic shape models can be built
  • Provides enough background so that additional practice and instruction can occur
  • It will be insufficient to fully train new personal to a level in which they could run an entire mission without support
• Specific things to learn
  • Be able to create landmarks and add images
  • Basic trouble shooting and fixing mis-registration
  • Perform tiling (both globally and BIGMAP)
  • Do iterations
  • Run residuals, geometry
  • Register images to shape model or maps
  • Autoregister
• Practice. A key component of this training is to practice. The practice allows for key concepts to become understood at a sufficient level to allow for more advanced concepts to make sense.

Student Prep

Because class time is limited, it is important to get the software and data installed before you show up to the conference. I will be available during the conference to help troubleshoot problems and help get your system functional before the class starts Wednesday morning. Once the class starts, I won't be able to ignore everyone else in the class to fix an install.

To maximize your learning in the class, I provide some information that will be beneficial to review.

• Stuff to read (links below)
  • Gaskell's 2008
  • Palmer's 2016, sections 2.4 and 5

Required Tasks To Complete Before Class Starts

• Sign the Licensing Agreement. This must be on file before the software can be distributed. //Complete//
• Download SPC software -- encrypted link will be sent only to class attendees

• Compile and install SPC. https://oort.psi.edu/public/1a09b8/dl/spc_v3.1B2.zip (password will be sent via a separate email)

  • Installing SPC Instructions

• Download sample data. The data volume is large, so it is important to do it ahead of time. Some of the files need to be expanded and moved.

  • Starting directory & SPICE (600MB)

    • You can put this directory anywhere (called topSPC). It is the base directory for the SPC work.

    • https://oort.psi.edu/public/98a344

    • You can go into the topSPC/ORex/DATA directory and uncompress the files using "gunzip *.gz"
  • Images:

    • I've broken them up into two parts to make them easier to download and compressed them. These <filename>.DAT files need to be moved into the topSPC/IMAGEFILES directory.

    • Approach (300MB): https://oort.psi.edu/public/1b733b

    • Preliminary Survey (1GB): https://oort.psi.edu/public/d0e1ec

    • You can uncompress the files using "uncompress *.Z"
  • Support Tools:
    • Over time, I have found that there are many nice helpers for SPC that do well if organized into its own area. They include scripts, programs and image lists. I've included some here. I suggest putting these two directories in /opt/local/spc/

Extra software that is useful

• Software - Please load the following

  • MacPorts - http://www.macports.org/install.php

  • gnuplot - Installing using MacPorts, "sudo port install gnuplot"

  • imagemagick Installing using MacPorts, "sudo port install ImageMagick"

  • GraphicConverter -- http://www.lemkesoft.de/en/products/graphicconverter/

• SPC tools - This is a suite of tools that make measuring pixel/line locations and offsets easier. This is not required and class time won't be used for installing this. Install instructions are coming soon
  • apache -- The is installed as default for most UNIX (and Mac) systems.
  • spc_tool javascript libraries
  • updateDisplay.sh - script to convert SPC output to a web-accessible format

  • How to install and run - SPC-GUI-tools
