US 10,002,430 B1 · Training system for infield training of a vision-based object detector

Abstract

Described is a training system for training a vision-based object detector. The system is configured to run an object detector on an image of a cleared scene to detect objects in the cleared scene. The object detector includes a support vector machine (SVM) or similar classifier with a feature model to generate an SVM score for object features and a spatial bias threshold to generate augmented object scores. The system designated detected objects in the cleared scene as false detections and, based on that, updates at least one of the feature model and spatial bias threshold to designate the false detections as background. The updated feature model or updated spatial bias threshold are then stored for use in object detection.

Dependent claims

The vision-based object detector, the system comprising:

one or more processors and a memory, the memory having executable instructions encoded thereon, such that upon execution of the instructions, the one or more processors perform operations of:
running an object detector on an image of a cleared scene to detect objects in the cleared scene, the object detector having a detection classifier with a feature model to generate a detection score for object features and a spatial bias threshold to generate augmented object scores;
designating detected objects in the cleared scene as false detections;
and
updating at least one of the feature model and spatial bias threshold to designate the false detections as background;
and
storing the updated feature model or updated spatial bias threshold in the vision based object detector.

A method for training a vision-based object detector, the method comprising an act of:

causing one or more processors to execute instructions encoded on a non-transitory computer-readable medium, such that upon execution, the one or more processors perform operations of:
running an object detector on an image of a cleared scene to detect objects in the cleared scene, the object detector having a detection classifier with a feature model to generate a detection score for object features and a spatial bias threshold to generate augmented object scores;
designating detected objects in the cleared scene as false detections;
and
updating at least one of the feature model and spatial bias threshold to designate the false detections as background;
and
storing the updated feature model or updated spatial bias threshold in the vision based object detector.
