Chapter 4. GPS-enabled Time-lapse Recorder

One of the possible uses of the Raspberry Pi camera module is the recording of time-lapse captures, which takes a still image at a set interval over a long period of time. This can then be used to create an accelerated video of a long-term event that takes place (for example, a building being constructed).

One alteration to this is to have the camera mounted on a moving vehicle. Use the time lapse to record a journey; with the addition of GPS data, this can provide an interesting record of a reasonably long journey.

In this chapter, we will use the Raspberry Pi camera module board to create a location-aware time-lapse recorder that will store the GPS position with each image in the EXIF metadata.

To do this, we will use a GPS module that connects to the Pi over the serial connection on the GPIO port and a custom Python program that listens for new GPS data during the time lapse.

For this project, we will use the Raspbian distribution. Instructions...
