Keyence and Roboflow

Keyence is built around rule-based machine vision, Roboflow is built on deep learning

Rules work when every part looks the same. When parts, lighting, and defects vary, manufacturers like USG, Pella, and Rivian train deep learning models with Roboflow on the cameras already on their lines.

Why are companies choosing Roboflow?

Roboflow is enterprise vision AI infrastructure, used by more than half of the Fortune 100, with SOC 2 Type II, HIPAA, and air-gapped deployment. Over 2 million engineers use it to create datasets, train models, and deploy to production.

  • Learns from your parts

    Deep learning models train on your own images, so they handle natural variation in finish, lighting, and position instead of breaking on a fixed threshold.

  • Tougher defects, caught

    Find subtle, irregular defects on wood, castings, textiles, food, and textured surfaces, where fixed rules tend to flag good parts and miss bad ones.

  • Any camera, models you own

    Run on the cameras already on your line, choose RF-DETR or YOLO26, and export the weights.

  • Roboflow Annotate labeling cans with AI box prompting

    Fast data labeling

    Label data quickly with a suite of AI-assisted annotation tools to augment human labeling or fully automate your data labeling pipeline.

  • Workflow blocks for notifications and integrations

    Build vision AI applications with ease

    Use a low-code open source platform to simplify building and deploying vision AI applications.

  • A video stream with detections and its NVIDIA Jetson device running

    Edge deployment

    Cloud and edge deployments (NVIDIA Jetson, Raspberry Pi, or mobile devices) for real-time, on-premise inference.

  • A list of NVIDIA Jetson devices and their status

    Devices for every scenario

    Software, compute, cameras: all the tools you need to deploy vision AI.

  • Logos of OpenAI, Microsoft, Meta, Anthropic, Google and Qwen

    Flexible model licensing

    Choose from a range of licensing options to fit your needs, whether for commercial use, private deployment, or collaboration across teams.

Add deep learning to your Keyence line

  • Keep the tools that work

    Keep Keyence measurement and code reading where rules do the job, and send the harder defects to a deep learning model.

  • Train on your Keyence images

    Label images from your Keyence cameras with Auto Label and train a deep learning model in days.

  • Deploy next to the line

    Send frames from your Keyence camera to a Roboflow model on a Jetson or server, and return results to the PLC through Workflows.

Compare Roboflow and Keyence

Keyence provides integrated cameras, controllers, and inspection tools for factory automation. Its VS series (opens in a new tab) combines AI with rule-based machine vision. Roboflow gives manufacturers control over the deep learning models behind their inspections: which architecture to use, what examples it learns from, and where it runs.

That control matters when acceptable variation is difficult to describe with fixed rules. Wood grain, casting textures, and irregular defects can make good and bad parts look deceptively similar. With Roboflow, train a detection or segmentation model on representative production images, test where it succeeds and fails, and retrain as new examples arrive. When defective parts are too rare to build a useful training set, Roboflow’s new anomaly detection support lets you train PatchCore or FoundAD on normal parts and flag unusual appearances for review.

For models that need labeled examples, Auto Label drafts annotations from a text prompt for your team to correct. Roboflow Agent helps select models and assemble inspection logic in Workflows. Engineers can also manage datasets, training, and inference through Roboflow’s MCP integration in ChatGPT (opens in a new tab) or their coding assistant.

Roboflow can extend an existing Keyence installation. Train on images archived from supported CV-X or VS systems, then run the model on a Jetson or industrial PC alongside the existing equipment. Enterprise options provide industrial integrations, offline deployment, and engineering support to connect the application with plant systems.

Start by testing the inspection on your own images in a private project on Roboflow’s free plan. Supported model weights are downloadable, and self-hosted inference does not consume Roboflow credits. Your team can keep improving the inspection as parts and defects change, with control over the data, model, and deployment.
