Image based systems for detecting information on moving objects

摘要

Systems and methods for generating images of an object having a known object velocity include imaging electromagnetic radiation from the object onto a sensor array of an imaging system, adjusting at least one of a shutter rate and a shutter direction of the imaging system in accordance with an image velocity of the image across the sensor array, and sampling output of the sensor array in accordance with the shutter rate and the shutter direction to generate the images. Systems and methods for generating images of an object moving through a scene include a first imaging system generating image data samples of the scene, a post processing system that analyzes the samples to determine when the object is present in the scene, and one or more second imaging systems triggered by the post processing system to generate one or more second image data samples of the object.

1. A system for generating image data of an object moving through a scene at a known object velocity, comprising:
a first imaging system that generates sequential image data samples of the scene; a post processing system configured to analyze the sequential image data samples to determine when the object is present in the scene; and one or more second imaging systems configured, when triggered by the post processing system, to generate one or more second image data samples of the object when the object is present, the one or more second imaging systems each including
a sensor array for generating the one or more second image data samples, and an adjustable shutter rate and an adjustable shutter direction such that the one or more second image data samples include complete image data of the object in a single sampling of the sensor array; the post processing system being further configured to utilize information of (a) a first time at which the object is determined to be in the scene, and (b) the object velocity, to calculate a second time at which to trigger the one or more second imaging systems, so that the one or more second image data samples are generated when the object is within a field of view of the one or more second imaging systems.
