운전자 졸음 경보기 & 피로도 분석기

Drowsy Truck Drivers

Drowsy driver crashes cost $12 billion and contribute to up to 35% of the 4,400 annual truck driver deaths. Fatigued drivers are often unaware of their condition, frequently driving for 3-30 seconds with their eyes totally closed! High miles and long hours make truck drivers prone to drowsy driver crashes. Drowsiness affects other transportation operators such as pilots, railroad engineers and ship operators. Fatigued operators can lead to serious consequences, as exemplified by the Exxon Valdez disaster.

*** 이계측기는 고속버스,비행기,선박운전자,자가운전자 어느 누구나, 졸음/피로로 인한 대형 사고를 예방할 수 있는 운전자의 졸음 경보기이다. 실제 미국에서만 운전자의 졸음운전으로 4400명의 운전자의 사망사고, 재산피해는 무려 약 20조원 정도에 이른다. 한국을 포함한 전세계적인 관점에서 본다면, 한마디로 엄청난 재난이 대책없이 매해 일어나고 있습니다.

Solution: The Copilot (모델명 일명 부조종사)

Attention Technologies at NREC has developed the Copilot, the first device to accurately detect and track drowsiness and provide a warning to the driver. The audible and visual feedback from the Copilot can help the driver maintain his alertness until he reaches a safe place to stop and rest. Drivers using the Copilot will have an additional safety net that will help them avoid catastrophic and deadly crashes.

Core Description

Attention Technologies at NREC has developed the Copilot, the first device to accurately detect and track human drowsiness and provide a warning to the driver. The Copilot provides a continuous real time measurement of eye position and eyelid closure. A direct measurement of drowsiness is calculated from the analysis of slow eyelid closures. In particular the Copilot calculates PERCLOS or percent eye closure, simply defined as the proportion of time the eyes are closed over a specified time interval. The Copilot provides a visual gauge representing the driver's drowsiness level and an audible warning when a preset drowsiness threshold is reached.

Benefits

The Copilot has the potential to prevent many of the deaths and injuries caused by drivers falling asleep behind the wheel. Since drivers are often unaware of their deteriorating condition, feedback from the Copilot alerting drivers of their condition can persuade them to stop and rest. In addition the Copilot can help drivers maintain their alertness until it is safe to stop.

Approach

The Copilot design is based upon a uniqe patented technology that uses eye closures to detect drowsiness. This method has been scientifically proven to be the most effective way to detect drowsiness. When the Copilot detects that a driver is getting drowsy, the Copilot will beep. The driver can then look at the display to determine the level of drowsiness and take the appropriate action. The Copilot takes advantage of the way the human eye reflects light. The monitor captures two simultaneous images of the subject at two wavelengths of light. The two images are processed using a simple and computationally inexpensive technique. The result is a rapid and direct signal indicating the position, height and width of the pupil. Alternative systems using a single image typically require expensive and powerful computers and employ complex and computationally expensive image processing algorithms.
