Improving the GUI

[kvos]

Hi all,

As discussed with @KateBrodie @SRHarrison and Brittany last week, I will be helping to improve the GUI in view of the CIRN bootcamp.

Here are the first 2 improvements that were suggested:

1. Intrinsic camera parameters
   1a. Populating the popup menu with the different cameras from the script makeLCPP3.m
   1b. Being able to set a custom camera and input the intrinsic camera parameters directly on the GUI, without having to edit makeLCPP3.m.

2. Coordinate conversion: the GUI uses SuperTrans (from OpenEarth tools) to convert GPS coordinates (WGS84) from the image metadata into a user-defined coordinate system (the one used to survey the GCPs). SuperTrans uses the EPSG Geodetic Parameter Registry, which contains most coordinate systems but misses a few (for example NAD83 / North Carolina). It was therefore decided to give the user the option to enter all the inputs (GCPs and camera extrinsic parameters) in his local Argus coordinates
   2a. Add an option where the user can enter the inputs in local Argus coordinates.

This channel is here to discuss the changes and propose further improvements.

Thanks @kvos.
Can you clarify: did you already make those additions to your branch or is this note just for discussion at this point?

[kvos]

it's just for discussion.

but I've done changes 1a and 1b.
In the intrinsic camera parameters panel (tab 2), there is an option for "custom" camera. The user can then input the lens calib parameters and proceed to the next step.
In case the user wants to save the custom camera, the button "save" allows to save the camera intrinsic parameters in a mat file. In a successive run, the saved custom camera can be loaded with the "load" button.

I also made change 2a.
I added in the inputs structure a field inputs.localCoords that can be activated (0 or 1) on the GUI by ticking the checkbox Local in the rectification settings (see screenshot below).
When inputs.localCoords = 1, the user has to provide:

• the GCPs in local Argus coordinates
• the camera extrinsic parameters also in local Argus coordinates (hard!)
