摘要： Methods and apparatus providing model-based feature tracking for location assessment of a sensor platform, or tracking of a feature are disclosed wherein a series of predictive models are developed to predict a location of features in subsequently acquired sensor data. Feature location data acquired by a sensor in a previous platform position assessment is used to build a model corresponding to anticipated feature locations in data acquired for a present platform position assessment.

摘要： Apparatus suitable for tracking a road vehicle from an aerial platform uses a correlator (5) for processing data received from a thermal imager (1). The apparatus derives a binary template for use by the correlator (5), the template (13) being based on points of high curvature (12) in an object to be tracked. The invention shows a significant reduction in mistracking and drift compared with conventional correlation trackers under the conditions of high density of features similar in nature to the object of interest, such as typifies the imagery obtained from a ground-pointing camera mounted on an aerial platform.
