CONCLUSION
• Successfully integrated Lidar v3• The accuracy of distance measurement is 1cm• An alert is triggered when a object comes within a pre-set distance (representing the BS Zone)•Affordable and reliable blind spot monitoring system
Future works: Need to be tested in different environmental/lighting conditions
