Improves camera pointing and a whole lot more!

Overview Parameters

Description

The jigsaw application performs a bundle adjustment on a group of overlapping Isis, level 1, cubes from framing and/or line-scan cameras. The adjustment simultaneously defines the selected image geometry information (camera pointing, spacecraft position) and control point coordinates (x,y,z or lat,lon,radius) to reduce boundary mismatches in mosaics of the images.

This functionality is demonstrated below in a zoomed-in area of a mosaic of a pair of overlapping Messenger images. In the before jigsaw mosaic on the left (uncontrolled), the features on the edges of the images do not match. In the after jigsaw mosaic on the right (controlled), the crater edges meet correctly and the seam between the two images is no longer visible.

Before jigsaw (uncontrolled) After jigsaw (controlled)

The jigsaw application assumes spiceinit has been run on the input cubes so that SPICE is included in the Isis cube labels in the Kernels group. In order to run the program, the user must provide a list of input cubes, an input control net, the name of an output control net, and the adjustment parameters. jigsaw outputs a new control net that includes the initial state of the points in the network and their final state after the adjustment. The initial states of the points are tagged as a priori in the control net, and their final states are tagged as adjusted. The measured sample/line positions associated with the control points in the net are not changed. SPICE in the cube labels is updated at the end of the adjustment only if the bundle converges and the UPDATE parameter is selected.

Optional output files can be selected to provide more information for analyzing the results. BUNDLEOUT_TXT provides an overall summary of the bundle adjustment. It lists the user input parameters selected and tables of statistics for both the images and the points. The image statistics can also be written to a separate CSV file and likewise for the point statistics with the OUTPUT_CSV option selected. RESIDUALS_CSV provides a table of the measured image coordinates and the final sample, line, and overall residuals in both millimeters and pixels.

The functional model for the bundle adjustment is the collinearity condition. It stipulates that the camera perspective center, a ground point, and its associated image point measurement be collinear. The diagram below demonstrates the collinear condition in a bundle adjustment. The vectors formed by connecting each object space point (target surface x,y,z) and its corresponding image space points (sample,line) form a bundle of light rays.

Known Issues

Running jigsaw with a control net containing JigsawRejected flags may result in bundle failure

When running jigsaw with Outlier Rejection turned on, control points and/or control measures may be flagged as JigsawRejected in the output control net file. If this output net file is then used in a subsequent jigsaw run, these points and measures will be erroneously ignored, potentially causing the bundle adjustment to fail.

--Workarounds
  1. Run jigsaw with Outlier Rejection off.
  2. Do not use the output control net file in subsequent jigsaw runs.
  3. Convert the output control net file from binary to PVL and back using cnetbin2pvl and cnetpvl2bin. This will clear the JigsawRejected flags.

Solving for the target body radii (triaxial or mean) is NOT possible and likely increases error in the solve.

With the current jigsaw implementation, it is NOT possible to individually solve for either the mean or triaxial radii as seperate calculations in the bundle adjustment. More specifically, the target body radii has no effect when solving for individual points and thus cannot be solved for in the bundle. A local radii solve is already part of the sequence of equations that jigsaw uses to compute various partial derivatives to populate the solve matrix. A seperate mean or triaxial radii solve can be applied to the target body and the partials from this separate application are added to the solve matrix. This option adds additional computation time to jigsaw and creates additional uncertainty/error in the bundle adjust. We advise the mean and triaxial radii solve be avoided.

If you are trying to generate a spheroid from a control network there are other programs that can do this for you. An easier but more naive method is ingesting the OUTPUT_CSV from your network, gather local radii information from those points, then generate a sphereiod from those local radii.

Solve Options: OBSERVATIONS


Description

This option will solve for SPICE on all cubes with a matching observation number as though they were a single observation. For most missions, the default observation number is equivalent to the serial number of the cube, and a single cube is an observation. However, for the Lunar Orbiter mission, an image has a defined observation number that is a substring of its serial number. This feature allows the three subframes of a Lunar Orbiter High Resolution frame to be treated as a single observation when this option is used; otherwise, each subframe is adjusted independently.

Community Sensor Model Options: CSMSOLVESET


Description

Specify one of the parameter sets from the CSM GeometricModel API to solve for. All parameters belonging to the specified set will be solved for.

Type string
Internal Default none
Option List:
Option Brief Description
VALID Solves for CSM parameters that are not NONE.
ADJUSTABLESolves for real or fictitous CSM parameters.
NONADJUSTABLESolves for fixed CSM parameters. Solve for fixed CSM parameters. These parameters are generally not adjusted but do have uncertainty which can help constrain the solutions and improve a posteriori uncertainties for other parameters.
