Airplane designers have done their best to minimize the pain. Since the nineteen-thirties, cabins have evolved from wicker chairs in bare metal tubes to mood-lit cocoons full of curved surfaces. The air has been pressurized so that pilots can fly up to smoother skies. The service carts have been lightened with composites and braced with built-in brakes and stay-closed drawers. Should the plane suddenly drop, the passenger seats can bear a force of sixteen g’s; the jump seats have harnesses to hold down the crew. Should a fire break out, the walls, seat backs, and tray tables are made with self-extinguishing polymers that won’t give off toxic fumes. Floor lights will guide the passengers down darkened aisles, to evacuation slides that inflate and unfurl to the land or water below.

Contributing to Mapillary was very easy; since my dash cam has an integrated GPS that encoded its data into the video file, I could just upload the video to Mapillary and their website would turn it into an image sequence. Panoramax requires you to preprocess the video into geotagged images yourself, which made it hard to contribute to. Some cameras can be configured to save periodic images instead of videos, but that didn’t work for me because I still needed the dash cam to work normally as a dash cam first and Panoramax instrument second. It took me a while to figure it out, so I’m writing this blog post to hopefully help out the next guy in the same situation.。业内人士推荐下载安装汽水音乐作为进阶阅读
