You can use a peeled-apart DVD and a USB web camera for a fraction of the cost. It's a design Public Labs came up with around 2012: https://hackaday.com/2012/08/27/turning-a-webcam-into-a-spec... Public Labs even developed a modified design that works with most smart phone cameras, among their follow-up work (such as testing high-end cameras: https://publiclab.org/notes/stoft/10-23-2016/high-rez-webcam... ) The spectral response of the sensor is not linear, as it is designed to imitate human vision - and as anyone who read early 2000's digital camera reviews can tell you, even fancy cameras from well known manufacturers can have noticeably different color response. One benefit of Rasp Pi cameras is that genuine cameras could be evaluated and characterized, but counterfeits and such will be a problem. Same is true of USB web cams, I suppose. |
