Image processing system to align a target object in a target object image with an object model

摘要

An image processing system that may be used to detect changes in objects, such as damage to automobiles, compares a base object model, which depicts the object in an expected condition, to one or more target object images of the object in the changed condition. To do so, the image processing system first processes a target object image to detect one or more predefined landmarks in the target object image using one or more correlation filters. The image processing system then uses the detected landmarks to determine a camera model for the target object image and uses the camera model to correct for camera distortions and to align the target object depicted in a target object image with the object in the base object model to put these objects in a common frame of reference for use in subsequent image processing. The image processing system may then determine contours of the target object within the target object image by overlaying an aligned base object model with the target object image, may remove background pixels or other extraneous information based on this comparison, and may perform a statistical processing routine on the identified target object image to detect changes to the target object as depicted in the target object image as compared to the base object model.
