Google’s New Patent Helps Drivers Keep Attention While Driving
We are current in the era of intelligent driving, and vehicles with intelligent driving and assisted driving functions are constantly emerging.
However, since the technology of intelligent driving is not perfect, some functions still have certain risks if self-driving is applied, so people need to keep attention while driving.
Whether the driver is paying attention to driving is a technical problem. Current technologies identify driver’ s attention by tracking their behaviors, such as touching the steering wheel, driver’s eyes, facial expressions, eye blinking speed etc. However, these technologies have some limits. They are not very friendly, for example the driver needs keep hands on the steering wheel. Or they are prone to misjudgment, such as eye blink detection may not recognize whether the driver is looking at the scenery outside the window.
Recently, Google disclosed a patent “VEHICLE OCCUPANT ENGAGEMENT USING THREE-DIMENSIONAL EYE GAZE VECTORS”. According to the description, it can more accurately locate the relative position and specific components in the vehicle that the user is viewing through the 3D gaze vector of the eyes, such as whether the user is looking at the rearview mirror, instrument panel, etc.
It can determine the three-dimensional eye gaze vector based on the occupant’s facial plane. Using the 3D position of the occupant’s head/eyes in the cabin space and the 3D eye gaze vector, it is possible to more accurately determine the position in the 3D cabin space that the user is looking at, such as the rearview mirror, the vehicle’s head unit, the vehicle’s instrument displays, front windshields of vehicles, etc.
This technology can effectively track the driver’s attention and avoid the accidents caused by the driver’s distraction. Datatang has developed Multi-race — Driver Behavior Collection Data and Driver Behavior Annotation Data to support the large-scale application of driver’s behavior recognition. Datatang strictly abides by the relevant regulations, and the data is collected with proper data collection authorization agreement and under the ISO 27001 Privacy Information Management System certification and the ISO9001 Quality Management System certification.
The data includes multiple ages and multiple time periods. The driver behaviors includes Dangerous behavior, fatigue behavior and visual movement behavior. In terms of device, binocular cameras of RGB and infrared channels were applied.
The data includes multiple ages, multiple time periods and behaviors (Dangerous behaviors, Fatigue behaviors, Visual movement behaviors). In terms of annotation, 72 facial landmarks (including pupils), face attributes, gesture bounding boxes, seatbelt bounding boxes, pupil landmarks and behavior categories were annotated in the data.
Due to technical limits, current intelligent driving vehicles cannot driver alone without human’s intervention. We believe that the real self-driving vehicles will come in the near future.
