SYSTEM AND METHOD FOR DETECTING OBSTACLES
First Claim
1. An obstacle detecting system, comprising:
- a transmitting unit which emits a laser signal;
a micro electro mechanical system (MEMS) scanning mirror which reflects the laser signal to scan detecting regions and divides the detecting regions into a plurality of regions to scan the plurality of regions at point intervals different among the plurality of regions;
a receiving unit which receives the laser signal transmitted from the MEMS scanning mirror to detect information of an object detected in the detecting regions; and
a processing unit which issues an alarm or transmit a braking command through the information detected in the receiving unit,wherein the detecting regions are set at an angle of view at which obstacles in front of a vehicle are detected and a cut-in situation when a vehicle in a next lane suddenly cuts in is detected.

Abstract
The present invention provides an obstacle detecting system and method. The obstacle detecting system includes: a transmitting unit which emits a laser signal; a MEMS scanning mirror which scans detecting regions set at an angle of view at which obstacles in front of a vehicle are detected and a cut-in situation when a vehicle in a next lane suddenly cuts in is detected, and divides the detecting regions into a plurality of regions to scan the plurality of regions at different point intervals; a receiving unit which receives the laser signal transmitted from the MEMS scanning mirror to detect information on an object detected in the detecting regions; and a processing unit which detects the obstacles and the cut-in situation through the information detected in the receiving unit to issue an alarm or transmit a braking command.

11. A method for detecting an obstacle, comprising steps of:
-
emitting a laser signal; reflecting by a micro electro mechanical system (MEMS) scanning mirror the laser signal to scan a plurality of regions which is obtained by dividing detecting regions set at an angle of view at which obstacles in front of a vehicle are detected and a cut-in situation when a vehicle in a next lane suddenly cuts in is detected at different point intervals; receiving the laser signal transmitted from the MEMS scanning mirror to detect information of an object detected in the detecting regions; and detecting the obstacles and the cut-in situation through the information detected in the receiving unit to issue an alarm or transmit a braking command. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
