Looking for a software package that can extract data from a series of photos of a physical meter. Most gauges (e.g. thermometers, barometers, pressure gauges) are inexpensive and provide accurate, useful data, but reading them is a manual process. A general purpose image recognition tool to extract readings from time-stamped images (taken from an old cell phone or web cam on time lapse, for example) would allow automated construction of time-series data for later analysis.
Here's examples of a digital thermometer / hygrometer / clock and an analog electricity meter that this could be used on:
You can assume the operator has some ability to control the scene, i.e. placement of objects, lighting, and so forth. For example, on the digital meter, relative humidity (46%) is tough to read, but better lighting might clear that up. (Both images are scaled down for inline display; view in new window for slightly higher res.)
No restrictions on platform, operating system, or license and whether the package can read some meters but not all (e.g. digital but not analog).
