Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If real-time monitoring of driver behavior is implemented using image acquisition and detection algorithms, then distracted-driving detection capability is improved, but system complexity and computational resources increase
Solution Approach 1:
The monitoring system is divided into independent functional modules: image acquisition module, detection algorithm module, determination module, and alarm module. Each module performs a specific task (capturing images, detecting target objects, determining distracted behavior, and sending alarms), which simplifies the overall system architecture while maintaining high detection accuracy through specialized processing in each segment.
Solution Approach 2:
The system pre-establishes a database of target objects associated with distracted behaviors (mobile phones, cigarettes, food, drinks) and their typical positions. Detection algorithms are pre-trained to recognize these objects, enabling rapid real-time detection without requiring complex runtime decision-making, thus reducing computational complexity while maintaining accuracy.
2Measurement precision
If multiple detection algorithms and filtering mechanisms are used to improve detection accuracy, then measurement precision is improved, but processing time and computational load increase
Solution Approach 1:
The system applies detection algorithms selectively rather than uniformly to all image regions. It focuses computational resources on areas where distracted objects are most likely to appear (near the driver's face and hands), using probability thresholds to filter out low-confidence detections. This partial application of detection reduces processing time while maintaining high accuracy for relevant targets.
Solution Approach 2:
The system uses probability values from detection algorithms as feedback to continuously refine its determination process. Detection results with probability values above a threshold are retained and used for determination, while those below are discarded. This feedback mechanism allows the system to adapt to varying detection confidence levels and maintain accuracy without requiring excessive processing of low-quality detections.
3Adaptability or versatility
If comprehensive monitoring of various distracted behaviors is implemented, then monitoring coverage is improved, but false detection rate increases
Solution Approach 1:
The system assigns different monitoring characteristics to different types of distracted behaviors based on their local context. For example, mobile phone detection focuses on hand-held positions near the driver, while cigarette detection focuses on areas near the mouth. Each target object type has its own detection parameters and probability thresholds, allowing comprehensive coverage while reducing false detections by adapting to the specific characteristics of each behavior type.

AI summary
A distracted-driving monitoring method, system and an electronic device are provided. The distracted-driving monitoring method includes: acquiring an image of a driver; detecting a target object in the image to obtain a detection result; obtaining a determination result of a driving behavior according to the detection result; and sending an alarm signal when the determination result indicates that a distracted-driving behavior occurs. Through at least some embodiments of the present disclosure, the distracted-driving behavior of the driver can be monitored in real time and alarmed, thus urging the driver to concentrate in driving, to ensure safe driving and avoid traffic accidents. In addition, the specific type of the distracted-driving behavior can also be determined and different alarm signals can be given, which can be used as a basis for law enforcement or for data collection, data analysis, and further manual confirmation; thereby solving the problem of traffic accidents caused by not monitoring the distracted-driving behavior of the driver during driving.
