Records photo sequence + GPS + INS-based orientation

A desktop application is used for the full integration of Photos+GPS+IMU

Contact the author for further details

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

What’s Captured and How to Download the Data?

The data will be recorded in your device’s internal storage in the following folder:
