Google Releases Key Part of Street View Pipeline

New submitter drom writes "Google released a key part of their Street View pipeline as open source on Tuesday: Ceres Solver. It's a large-scale nonlinear least squares minimizer. What does that mean? It's a way to fit a model (like expected position of a car) to data (like GPS positions or accelerometers). The library is completely general and works for many problems. It offers state of the art performance for bundle adjustment problems typical in 3D reconstruction, among others."

Problem is

Problem is that it's not that good technology from Google. Sure, it works for larger cities and streets, but they might be checked manually anyway. However, my city has tons of alleys, sideways and small roads. They aren't even straight streets, most curve and go pretty much randomly. Not that it's bad, it makes for a nice and warm feeling city (not so planned and modernized), but after Google street view cars visited here you can see the sheer amount of problems in their technology. For example, most of the street lines seem to go into walls and buildings instead of staying in the roads. The positions are tricky. If you want to click to side street, you will usually be clicking towards a buildings wall, which looks just stupid. Good effort I guess, but there is much better technology out there.
