Model, Drive Control (ModDrC)

Type: Stereo Model Management

 

Drives to all control points in all models to generate a report of control point measurements in models.

Detailed Description

This application drive the operator from model to model to measure all the control points in the block in every model that see them.  The measurements are used to generate a report of the accuracy of the models.  In order to use the tool you must first open multiple models in the Model Manager (ModMan).

 

Procedure

 

1. Open multiple models in Model Manger (ModMan).

 

2.  Start Model, Drive Control (ModDrC).  The first menu allows the user to edit the parameters and chose a control file before beginning the measurement process.

 

ModDrCMenuStart

The model precision application menu.

F1, or left click

Start the measurements

 

F7

Allows access to the user parameters discussed above.  Parameter descriptions are given in step 3 below.

 

F12

Close application

 



 

 

3. You may also wish to change the parameters:

ModDrCParams

Parameters:

Control input mode

When model files are created, the active control point are saved.  The application can use these saved points or a different selected control file.

Alternative control file

If the control input mode is "Selected control file", the control in this file will be used.

Random Motion Distance

When driving to points the cursor is shifted randomly in all three axes in order to keep measurements independent.  This can be disabled by setting this value to zero, but leaving it at least several times the GSD is highly recommended.

 

Show model data

There is an optional block of data that shows the model name, the residuals from the mean measurement, the pixel radius (percent of the distance from the image center to the corner), and the image names for each model (see the example in step 6).

 

File recording mode

User can chose to record nothing to the output file, append to output file, or overwrite the output file

 

Output file

The path to the output file

 

4.  Left click or push F1 to start measuring.  The application will drive to all the points to measure.  The menu options during this phase.

ModDrCMenuMeasure

 

F1, or left click

Measure the control point at the cursor location, and then move to the next point.

 

F2

If a point is too close the edge of the model or obscured you can skip a model.

 

F4

A bail out to restart the process (all measurements will be lost).

 

F5

Records the data collected so far to the output file.  This does not delete any data or prevent the process from continuing.

 

F7

Allows access to the user parameters discussed in step 3 above.  Note that change the "control input mode" or the the "alternative control file" will cause the process to restart and all measurements will be lost.

F12

Exit the application.  All measurements will be lost.

 

Your progress through the stack of models is show on the main window as shown below.

ModDrCProgress

 

6. The accuracy statistics are saved to the output file.  Below is an example with model specific data turned on.  Root mean squared error, or RMSE, is with regard to the differences of individual measurements from the control coordinate.  The maximum differences are the maximum deviations from the mean in each axial direction.  RadL and RadR are descriptions of how far a point was away from the center of the raw image.  100% is as far away as possible, 0% is exactly in the center.
