Abstract: An enhanced light detection and ranging (LiDAR) assisted vehicle navigation system includes a global positioning system (GPS). A LiDAR device is in communication with the GPS generating and transmitting LiDAR signals reflected off a target proximate to a vehicle. Multiple vehicle sensors including at least a LiDAR sensor receive the LiDAR signals reflected off the target as a point cloud of data. A line profile of the target is used to identify if blooming is present. A characterization device performs a characterization analysis to identify an existence and extent of blooming of the LiDAR signals using the line profile of the target. A filter receives an output of the characterization device and removes the blooming if present to provide edge detection of the target.
