The appearance of agricultural products is crucial. Colors indicate such parameters as maturity, defects, etc. Quality grades are decided by graders and are often inconsistent. Machine vision technology provides solutions to all these problems. Designed for the machine vision market, the FLEX series has four PCIe 3.0 expansion slots for installing motion controller cards, GPU/FPGA/VPU cards, and PoE Ethernet cards developed by IEI, and has four IEEE compliant GBE Power over Ethernet (PoE) port 802.3AF, which allows direct connection to CCTV cameras without the need for a separate power supply.
