A method of performing real-time geo-registration of high-resolution digital imagery using existing graphics processing units (GPUs) already found in current personal computers, rather than the main central processing unit (CPU). Digital image data captured by a camera (along with inertial navigation system (INS) data associated with the image data) is transferred to and processed by the GPU to perform the calculations involved in transforming the captured image into a geo-rectified, nadir-looking image. By using the GPU, the order-of-magnitude increase in throughput over conventional software techniques makes real-time geo-registration possible without the significant cost of custom hardware solutions.
