Vision-Guided Navigation Technology

Seegrid’s patented vision-guided technology is deployed in distribution and manufacturing facilities automating materials handling tasks. The technology allows for vision-guided automated guided vehicles (AGV) to be easily installed and operated with no modifications to the environment or infrastructure. The vehicles are equipped with range-finding stereo cameras that record thousands of features along the route, allowing the vision-guided AGV to replay the route by making use of the recorded features to navigate. Vision-guided AGVs use Evidence Grid technology, an application of probabilistic volumetric sensing, that was invented and initially developed by Dr. Hans Moravec at Carnegie Mellon University.

The Evidence Grid technology combines multiple views of the environment to generate probabilities of occupancy for each point in space to compensate for the uncertainty in the performance of sensors and variability in the environment. The primary navigation sensors are Seegrid designed stereo cameras. The vision-guided AGV uses a 360-degree array of stereo cameras to capture images and builds a 3D map, which allows the vision-guided AGVs to follow a trained route without human assistance or the addition of special features, landmarks, or positioning systems. The vision-guided technology provides users with ultimate flexibility.
