Many people may imagine a large machine and budget when they hear of the introduction of an image-based identification device for industrial use.Aside from custom programs, if the hardware is an industrial Raspi such as PL-R4, it can be built inexpensively by utilizing a general-purpose camera and various sensors.It does not seem unreasonable for small-scale applications. The product PL-R4 ComputeModule4 (“RPI CM4”) being tested is almost identical to the hobby-use Raspberry Pi 4 (“Pi 4”). We were able to try it with the usual USB-connected webcam and a camera module that is also available from official sources. We connected a camera to see the difference, including settings unique to industrial…
