Abstract
Apparatus for scanning a moving object includes a visible waveband sensororiented to collect a series of images of the object as it passes through a field of view. An image processoruses the series of images to form a composite image. The image processorstores image pixel data for a current image and a predecessor image in the series. It uses information in the current image and its predecessor to analyse images and derive likelihood measures indicating probabilities that current image pixels correspond to parts of the object. The image processorestimates motion between the current image and its predecessor from likelihood weighted pixels. It generates the composite image from frames positioned according to respective estimates of object image motion. Image motion may alternatively be detected by a speed sensor such as a Doppler radarsensing object motion directly and providing image timing signals.
