Ask HN: How to identify the number of people on a bus? What kind of technology (LiDAR or ViDAR) would help us identify the number of people on a bus? People inside might have RFID / NFC technology with them, like badges, but we can't count on them 100% as someone might forget or not have that piece at all. Of course, buses will slow down when they come to a "checkpoint" to allow devices (cameras) to perform better scanning. By the way, it's a civil project, nothing to do with law enforcement. A huge convention center wants to know in advance, if 100 buses are coming, what number of participants to expect at their gate. |
