Method for estimating movement between two images
The patent US12020441B2 outlines a method and system for estimating the movement between two images captured by an image capture device. The method involves several steps, starting with the collection of data that defines each image. An initialization displacement vector is determined to characterize the displacement between the two images. An iterative algorithm is then implemented, which updates the displacement vector at each iteration based on an error function that minimizes the difference between one image and the transformed version of the other image. Additionally, the method collects information about the movement of the image capture device and various capture parameters, such as angular opening, zoom factor, and resolution. The initialization displacement vector is calculated by projecting the displacement between the images into the image plane, taking into account the movement of the device and the capture parameters.
The patent also describes an electronic device designed to implement this method. This device includes an input for collecting image data and is capable of determining the initialization displacement vector and executing the iterative algorithm. It is equipped to gather information about the movement of the image capture device and the relevant capture parameters. Furthermore, the device can set the initialization displacement vector to a specific optimized format. The claims emphasize the integration of movement determination and capture parameter analysis to enhance the accuracy of movement estimation between the two images, thereby providing a comprehensive solution for image processing applications.
