Time lapse video

This article was published in 2013, in Newsletter 106.

Time lapse is not only for laughs. It can produce convincing visual evidence of traffic conditions, which we all recognise, but which are hard to document. Consistent unloading in the bike lane, dangerous intersections, cash machine parking, over-ranking, etc.: we all recognise these, but how can we explain them to the public? Time lapse video can also offer a great tool for counts, or give a visual impression of traffic movements at a given location.

We are currently trying to round up experts who are are familiar with the CHDK (Canon Hack Development Kit) which allows a simple digital camera to be turned into a time lapse video tool (with movement detection etc.). We could deploy a number of such cameras in public locations, and offer our members access to this tool. If you have worked with CHDK, or if you have access to a dozen Canon cameras which are no longer required, we would like to hear from you. We would like to work with cameras for multiple deployment, and allow for loss and defects as they are placed in un-manned locations.
