The innovative driver assistant systems (IDAS) solution accelerator is part of the value-added APEX (Advanced Passenger Experience) services from HCL for the automotive industry. IDAS helps the driver in operating the vehicle safely and comfortably. The following solution accelerators are developed as part of the IDAS initiative:
Lane departure warning (LDW)
Traffic Sign Board Recognition (TSBR)
Reverse view Aid (RvAid)
Lane Departure Warning (LDW): LDW is an in-vehicle electronic system that monitors the position of the host vehicle within a roadway lane and warn the driver of an unintentional lane departure when the vehicle is traveling above a certain speed threshold and the vehicle’s turn signal is not in use. HCLT’s LDW solution accelerator is a forward looking, monocular vision-based solution that uses an algorithm to interpret video images to estimate vehicle state (lateral position, lateral velocity, etc.) and roadway alignment (lane width, number of Lanes, Lane Type, etc). It can detect different types of Lanes in various environmental and lighting conditions at variable speeds. Early warning Capability based on Time To Lane Crossing (TTLC) is also provided.
Traffic Sign Board Recognition (TSBR): TSBR is a vision based technology demonstrator which performs automatic detection and classification of traffic signs in a traffic scene. The HCL’s TSBR algorithms automatically detect, classify and recognize the traffic signs. Finally the recognized Textual, picture information of Sign content as well as indication of the category of traffic sign will be displayed. The TSBR system has Text, Number and Shape recognition engines which are employed for the recognition of STOP signs, Speed limits, prohibitory, cautionary/warning and guide signs.
Reverse view Aid (RvAid): RvAid is a vision based solution accelerator, which can stitch up to four video streams into a single large panoramic video. Strategically mounted cameras can provide the automotive driver improved rear and blind spot visibility on a seamless single display, without taking his eyes off on the traffic ahead. HCL’s RvAid solution uses four rear facing CCD/CMOS cameras, one mounted on each side-view mirror and the remaining two cameras on either side of the hood. The video stream from the cameras are seamlessly blended together and stitched to give the driver a unified side and rear view of the scene on a single screen. Hence, the system provides the advantage of minimum blind spot; driver friendly integrated rear and side view display and further assists the driver in parking the vehicle.
