Today was a nice and sunny winter Sunday, with outside temperatures around -6°C. From the weather camera capturing an image every minute, a time-lapse video covering approximately 12 hours is assembled. It shows the changing weather conditions plus a few cross country skiers enjoying themselves in the sunshine. It takes about 3.5 minutes to show. I think you also agree that the Raspberry PI weather camera does a pretty good job with the heater system keeping it in focus!
The video was created automatically by first generating a label in the bottom left corner of each image. The information about exposure and camera temperature sensors is taken from XML files generated by the on-board RPI software.
Second, 3 interpolated images between each pair of originals were created, effectively giving the impression of images taken every 15 seconds. The XML generation, image interpolation and labelling software is home grown.
