On-Camera Inference: Firefly DL Machine Vision Camera

Deep learning is a robust tool that allows system designers to rapidly automate subjective and complex decision-making and still provide higher quality products and enhanced productivity.

Users can deploy their trained neural network to the FLIR Firefly DL equipped with Neurotechnology, and the cost and complexity of systems can be reduced by making decisions on-camera without using a host computer.

The Firefly DL camera is lightweight, has a compact size and consumes minimal power, which collectively makes it perfect for integrating into desktop, mobile and portable systems.

Deep Learning for Faster Deployment and New Possibilities

With deep learning, precise solutions can be rapidly developed and deployed to address complex automation issues.

Deep Learning Inference On-Camera

The cost and complexity of the systems can be reduced by deploying the trained network to a Firefly DL camera. This prevents the requirement for a host system for classification jobs.
