Methods and systems for the image processing of a three-dimensional imaging system include a multi-processor embodiment wherein the image output by an image sensor is divided amongst the several multi-processors for processing in order to improve the frame rate of the three-dimensional imaging system. Since the frame rate of a three-dimensional imaging system utilizing an image-intensifier is not limited by the amount of useful signal light available for imaging but is instead limited by image processing capacity, this technology provides for the use of multi-core or multi-processor image processing methods to improve the frame rate. Additionally, locating the image processor in close proximity to the image sensor allows for faster image data communication between the image sensor and image processor, which further improves the frame rate of the three-dimensional imaging system.
