Using the railway network as a flatbed scanner
Summary
A detailed, hands-on account of building a DIY slit-scan camera mounted on trains to produce wide panoramic-like images by stitching lines captured from a moving camera. The piece covers the theory of slit scanning, hardware choices (industrial camera, mounts, sensors), data capture (accelerometer, GPS), processing pipelines, color experiments, and the challenges of post-processing, synchronization, and display. It concludes with future work and open-source code references.
