Abstract
Systems and methods for using image analysis techniques to assess unsafe driving conditions by a vehicle operator are discloses. According to aspects, a computing device may access and analyze image data depicting the vehicle operator. In analyzing the image, the computing device may measure certain visible metrics as depicted in the image data and compare the metrics to corresponding threshold values, and may accordingly determine whether the vehicle operator is exhibiting an unsafe driving condition. The computing device may generate and present alerts that indicate any determined unsafe driving condition.
Claims20
A system for assessing driving safety, comprising:
- an image sensor disposed on a vehicle and configured to capture image data, the image data comprising a plurality of image frames depicting a face of an operator of the vehicle;
- a non-transitory memory storing computer-executable instructions;
- and
- a processor communicatively coupled to the image sensor and the non-transitory memory, the processor being configured to execute the computer-executable instructions, wherein executing the computer-executable instructions causes the processor to:
- determine that an eye aspect ratio of the operator, as depicted in a first image frame of the plurality of image frames, is less than an eye aspect ratio threshold,
- determine a number of consecutive image frames subsequent to the first image frame, in which the eye aspect ratio of the operator is less than the eye aspect ratio threshold, and
- determine that an unsafe driving condition exists based at least in part on the number of consecutive image frames exceeding an image frame threshold.
A computer-implemented method, comprising:
- receiving image data captured by a sensor disposed on a vehicle, the image data comprising a plurality of image frames depicting a face of an operator of the vehicle;
- determining that an eye aspect ratio of the operator, as depicted in a first image frame of the plurality of image frames, is less than an eye aspect ratio threshold,
- determining a number of consecutive image frames subsequent to the first image frame, in which the eye aspect ratio of the operator is less than the eye aspect ratio threshold, and
- determining that an unsafe driving condition exists based at least in part on the number of consecutive image frames exceeding an image frame threshold.
A non-transitory computer-readable medium, comprising:
- a plurality of instructions which, when executed by one or more processors, cause the one or more processors to:
- receiving image data captured by a sensor disposed on a vehicle, the image data including a plurality of image frames depicting a face of an operator of the vehicle;
- determine that an eye aspect ratio of the operator, as depicted in a first image frame of the plurality of image frames, is less than an eye aspect ratio threshold,
- determine a number of consecutive image frames subsequent to the first image frame, in which the eye aspect ratio of the operator is less than the eye aspect ratio threshold, and
- determine that an unsafe driving condition exists based at least in part on the number of consecutive image frames exceeds an image frame threshold.
