Research Advances on Vehicle Parameter Identification Based on Machine Vision

With the rapid growth of highway transportation in recent years, the accurate identification of vehicle parameters is of great significance to the development of intelligent transportation and the operation and maintenance of transportation infrastructure. The rapid development and popularity of machine vision and deep learning in moving object detection have achieved new advances in vehicle parameter identification. The present study aimed to review the current status, new advances, and future trends in vehicle parameter identification based on machine vision and deep learning technologies from the two aspects of detection algorithm and applied research. Regarding detection methods, this paper introduced the basic principles, pros, and cons of these methods by classifying them into three categories:moving object detection, instance object detection, and fine-grained object detection. Research on the identification of vehicle parameters based on machine vision and deep learning was reviewed in detail, including the vehicle type, vehicle spatio-temporal parameters, vehicle weight parameters, and multiple parameter identification systems. Finally, this paper summarized research on vehicle parameters based on machine vision and deep learning, discussing the current challenges and possible future trends. The research demonstrates that suitable vehicle detection methods should be selected according to the actual requirements and the characteristics of each algorithm for different environmental conditions and vehicle parameters. At present, the detection method is still limited to single-vehicle parameters or the independent detection of several parameters. As identification accuracy and efficiency are difficult to meet simultaneously, future research should focus on the integration of new technologies to improve the accuracy, efficiency, robustness, and comprehensive vehicle parameter identification in complex environments for better application in practice.
