The interface shows:
--------------------------------
• a preview of the Camera (in the background behind the numbers and buttons)
• Accuracy ± ## m: Estimated accuracy of GPS- or Network- derived location
• ## MB Available: The amount of available storage space on your device. It will be continuously updated as you keep on taking photos
• ## Images: The number of images being taken in this session
• Capture: A button to start capturing photos in a sequence till you click “stop”. While recording, keep an eye on the number of photos taken and amount of available storage
• Stop: A button to stop recording photos.
• Delay: #### : The time delay from clicking “Capture” till the first photo is taken in milliseconds. 1000 is one second. Use this if you need time to mount the device on a vehicle or a selfie stick. Keep this as its default value for now
• Frequency: #### : The time between consecutive photos in millisecond. 1000 is one second. Do not to attempt to reduce it to a very small value as some devices cannot handle very intense processing in short time. Keep this as its default value for now.

Data Collection
------------------------
Start by calibrating the sensors by rotating the devices around its three axes, perform figure 8 or both
Ensure your location is determined by observing the value in “Accuracy ± ## m”
Collect the data.
While collecting, ensure you have a large overlap between the photos.
If you have control points, ensure some of the photos cover these photos
