PRECIPITATION REMOVAL FOR VISION-BASED PARKING MANAGEMENT SYSTEMS

摘要

Methods and systems receive a series of images and compare at least two of the images in the series of images to locate items that are in different positions to identify moving items. Such methods and systems further calculate a measure of the moving items within the series of images. Additionally, such methods and systems perform a continuously variable image correction to remove the moving items from the images to produce a series of corrected images. This “continuously variable image correction” increases the amount of image correction for a relatively higher measure of the moving items and decreases the amount of image correction for a relatively lower measure of the moving items, and does so continuously as the measure of the moving items changes within the series of images.

主权项

1. A system comprising:
a camera device acquiring a series of images; and a computerized device operatively connected to said camera device, said computerized device comparing at least two images in said series of images to locate items that are in different positions in said at least two images to identify moving items within said series of images, said computerized device calculating a measure of said moving items, said computerized device performing a continuously variable image correction to remove said moving items from said series of images to produce a series of corrected images, said continuously variable image correction increasing an amount of image correction for a relatively higher measure of said moving items and decreasing said amount of image correction for a relatively lower measure of said moving items continuously as said measure of said moving items changes within said series of images, and said computerized device outputting said series of corrected images.
