Method and system for producing classifier for recognizing obstacle
First Claim
1. A system for producing a classifier for recognizing an obstacle, comprising:
- a processor configured to;
display surface data of a plurality of obstacles measured by a distance measurement sensor in a two-dimensional (2D) coordinate system;
group and classify the surface data displayed in the 2D coordinate system for each obstacle;
project the surface data of each obstacle vertically to a ground surface coordinate system having an X-Y axis parallel to a ground surface;
set a plurality of feature references to analyze region based features displayed for each obstacle in the 2D coordinate system and calculate the respective feature references for each obstacle; and
produce the classifier by applying a weight to each of the feature references.
