Patent for License with Right to Enforce:Driver Alertness Monitoring
In particular, the invention can have applications for truck drivers, bus drivers, train operators, pilots and watercraft controllers and stationary heavy equipment operators, and students and employees during either daytime or nighttime conditions.
The invention robustly tracks a person’s head and facial features with a single on-board camera with a fully automatic system, that can initialize automatically, and can reinitialize when it needs to and provide outputs in real-time.
The system can classify rotation in all viewing direction, detects’ eye/mouth occlusion, detects’ eye blinking, and recovers the 3D (three dimensional) gaze of the eyes.
In addition, the system is able to track both through occlusion like eye blinking and also through occlusion like rotation.
Primary Application of the Technology
How the Technology Solves the Problem
- Uses computer vision to monitor both the eyes and the rotation of the driver's head through video sequences.
- Monitors full facial occlusion of the driver.
- Monitors alertness without shining light (artificial, infrared, LED, etc.) on the driver's face.
Class 340: Communications: Electrical
Communications - the handling of information or intelligence, restricted to the conveying of said information or intelligence between geographically spaced points. Information or intelligence is defined as being, matter which is handled by signaling systems or signaling devices (such as telegraph systems) or by that portion of nonsignaling systems or nonsignaling devices (such as power supply systems) which is designated in the arts as having a control function (such as the supervisory circuits which control the circuit breakers of an electric power network). Handling, as used above, is defined as being the active coaction between the tangible communication system or device and the intangible information or intelligence, and such coaction may assume various forms, such as transmission, storage, exhibiting, etc.Subclass 573.1: Human or animal
