The European Patent Office has issued a Decision to Grant for Rail Vision Ltd.’s patent application covering a novel system designed to significantly enhance the sampling rate of an imager detector for a Selected Region of Interest.
The patented system includes an imaging device and a processing unit that works in tandem to capture, analyze, and prioritize visual data from a train’s forward-facing camera. The imaging device collects multiple datasets from image frames during several handling cycles, while the processing unit identifies a specific region of interest based on the collected data.
The system can then acquire partial datasets from the SROI during residual time within those cycles, enabling higher sampling rates where it matters most.
Installed on the locomotive and oriented in the direction of travel, the system’s processing unit incorporates a tracking module that detects the rails, defines margins on both sides, calculates a safe braking line based on the train’s braking distance, and sets a safe zone. The SROI is positioned at the far end of this safe zone in the image frames, enabling early hazard detection and response.
“Securing this European patent is another strong validation of Rail Vision’s innovation,” CEO of Rail Vision David BenDavid said. “By boosting the sampling rate, we’re enabling train operators to detect hazards sooner, react faster, and improve functional efficiency to operate more safely. This technology is another step toward our vision of making railway transportation safer, smarter, and more efficient worldwide.”
With this latest grant, Rail Vision continues to expand its patent portfolio across strategic regions, supporting its mission to enhance railway safety and operational efficiency worldwide.
