The present invention provides a machine-vision-based electronic automobile insurance fee meter. The machine-vision-based electronic automobile insurance fee meter can capture a lane departure behavior, and record a distance and duration of a lane departure in a memory module; also can capture a following-too-close behavior, and record a distance and duration of dangerous following in the memory module; and also can calculate a journey-based mileage insurance fee, a total mileage insurance fee P being a product of a mileage L of a journey, a unit mileage (per kilometer) insurance rate Rkm and a safety floating factor f. The present technical solution charges the insurance fee according to the actual driving mileage, makes the charging of the insurance fee fairer and more reasonable, and encourages safe driving and driving less; and also can identify the most important dangerous driving risks including following-too-close and lane departure, making the pricing of the insurance fee more accurate and reasonable.
