JIC PicViewer

[rmackay9]

This PR adds a new offline picture viewer to MAVProxy for use in the Japan Innovation Challenge.

The design (and some code) borrows heavily from the Canberra UAV team's CUAV tool

How-to-use:

• MAVPicViewer application is installed along with MAVProxy (much like MAVExplorer)
• Use the MAVPicViewer icon to start the application (if visible) or start the mavpicviewer.py script. Once started 3 windows should appear:
  • Mosaic shows thumbnails of all images
  • Image Viewer shows the current image and allows users to set a single POI per image
  • SlipMap shows a map of the area with the current image's area highlighted in green. This improves the reviewers situational awareness

The Mosaic view (shown below) allows users to move through the images using the arrow keys. The selected image is shown with a green border. Images with a POI defined appear with a red border.

The Camera/Vehicle and POI locations are shown and if the image provides temperature the max temperature is shown along with the pixel coordinate.

The menu includes, "Open folder", "Show All", "Show POI", "Settings" (for setting the FOV) and "Quit"

The Image view shows the currently selected image. The user can also move to the next or previous image using the left and right arrow keys. A single POI can be selected by clicking-and-holding the left mouse button, moving the mouse and then releasing the left-mouse-button. The POI appears in red on the image. This same POI is also shown on the map. If the image provides thermal data then the hottest pixel is shown with a yellow square. This yellow square can be toggled on and off in case it gets in the way

The Map view shows a projection of the current Image on the map in green. If a POI has been defined it appears as a red square. As the user moves through images the Map updates.

The application can be started on windows using the MAVPicViewer icon from the start menu.

Enhancements planned:

• support saving the current image including POI to a new image
• allow users to click on the map and have the Image and Mosaic views jump to the closest image
• improve visibility of the POI's lat,lon (and also the cursor's lat,lon)
• reduce the Mosaic so that it only shows images with POI defined

Any and all feedback is very welcome

@rmackay9, you asked about using your custom icon for mavpicviewer: You'll want to take a look at ./windows/mavproxy.iss, which builds the MAVProxy installer exe. Within that, I've defined the icons for the start menu entries for MAVProxy and MAVExplorer.

Issue identified by Tridge has been fixed, thanks!
