Abstract
A moving object detecting system includes an image acquiring section, a feature extracting section, a background detecting section, a prediction parameter calculating section, a region estimating section, and a moving object determining section. The image acquiring section has a mobile imaging system and acquires image frames sequentially obtained upon movement of the imaging system. The feature extracting section extracts features of the acquired image frames. The background feature detecting section detects a background feature from the features. The prediction parameter calculating section obtains prediction parameters for predicting a motion of the background region upon movement of the imaging system in accordance with a positional relationship between the correlated background features. The region estimating section estimates a region where features detected from image frames obtained by the mobile imaging system may have been present in an image frame of the immediately preceding frame by using the prediction parameters. The moving object determining section determines whether a feature corresponding to the given feature is present in the estimation region, thereby checking the presence/absence of the moving object.
