METHOD AND SYSTEM FOR DETECTING GAPS BETWEEN OBJECTS
First Claim
1. A method for detecting gaps between objects comprising:
- acquiring a set of scanning data, each of the scanning data indicating, for a sequential location, a distance of a nearest object from a predetermined location;
filtering the set of scanning data to remove noise;
determining a set of derivative data from the set of scanning data;
analyzing the set of derivative data greater than a first predetermined distance;
defining a first set of gaps between objects based on the set of derivative data greater than the first predetermined distance; and
generating a report including the first set of gaps between objects.

Abstract
The present invention is directed to a method and system to determine gaps, such as parking spaces, between objects. A sensor acquires a set of scanning data. A noise filter unit filters the set of scanning data and a data derivative unit generates a set of derivative data from the set of scanning data. A data analysis unit determines locations of gaps by selectively analyzing the set of derivative data which exceed a first predetermined distance and/or a second predetermined distance. The gap definition unit determines the substantial locations, shapes, and sizes of the gaps based on the previously defined location from the data analysis unit. A report generation unit generates a report including the set of gaps defined by the gap definition unit. The report is displayed on a display in a color coded format easily visible and discernable to a driver of the automobile.
