Abstract: With the rapid advancement of the automotive industry, dashboard design confronts dual challenges in efficiency and innovation. This paper proposes a method of dashboard feature recognition and rapid modeling based on YOLOv8 algorithm, aiming to integrate historical design expertise to enable rapid prototyping during the initial design phase, thereby shortening the development cycle and improving design efficiency. First, dashboard base surfaces are constructed using styling surface and cross-section generation techniques to address the complexity of current design workflows. Second, the YOLOv8 algorithm is leveraged to efficiently identify critical features of dashboard skeletons, ensuring high accuracy while substantially accelerating recognition speed. Finally, matched feature modules are dynamically invoked based on recognition results and integrated with base surface models to swiftly generate design-compliant dashboard prototypes. Experimental results indicate that the trained recognition model achieves precision and recall rates of 75% and 75%, respectively, with mAP@0.5 and mAP@0.5:0.95 stabilized at 0.82 and 0.6. The rapid prototyping of dashboard based on the identification model can not only improve the design efficiency, but also ensure the accuracy and innovation of the design, which provides a new technical path for the design of automotive dashboard.
