i.MX 8M Mini Single Board Computer for Embedded Vision Applications

In the last few years, the trend toward miniaturization has highly impacted the world of vision technology. A classical machine vision system consisted of an industrial camera and PC, which were expensive and difficult to handle. In contrast, an embedded vision system offered a viable alternative to machine vision systems by replacing them with processing boards with support for board-level cameras.

These two developments – the miniaturized PC and the powerful camera have made it possible to design compact vision systems for specific applications. The benefits of using an embedded vision system include small size, lightweight, low unit costs, and low energy consumption.

Lately, iWave delivered i.MX 8M Mini Single Board Computer to a deep tech company to aid them in designing high-quality gemological instruments for testing the quality of gemstones and diamonds. There are multiple testing and characterization procedures involved in gemstone testing. The client required off-the-shelf computing hardware with a wide range of interfaces to speed up their product development time with reduced risk.
