摘要:

本文提出了一种基于合成图像数据集的挖掘机关键点识别方法,通过虚拟模型和场景的随机自动化以及关键点坐标和遮挡信息判定,生成多样化的合成图像,并利用基于平面视觉的深度神经网络完成关键点识别,解决了传统大规模数据集采集困难的问题。试验结果显示:该方法提高了关键点识别精度,归一化误差和正确关键点百分比分别为0.005 6和97.64%。因此,本文方法能够满足监控挖掘机的作业安全和工作效率的实际应用需求,同时避免了高质量工程数据集采集时安全风险高、时间/经济成本高、工况覆盖面窄且标签准确率低等问题,有助于深度学习和大数据技术在挖掘机工作状态识别方面的应用部署。

Abstract:

This paper proposes a method for excavator pose recognition using synthetic image datasets for model training. Initially, virtual models and scenarios are established. Programming is utilized to randomize the excavator pose, virtual camera position, and scene parameters. Subsequently, keypoint coordinates and occlusion information are computed to construct synthetic image datasets. Finally, excavator key points estimation is performed using a monocular camera. Experimental results demonstrate that training with synthetic image datasets improves model recognition accuracy, with a normalized error of 0.005 6 and a percentage of correct keypoint of 97.64%. Therefore, this method can meet the practical application needs of monitoring excavator operation safety and work efficiency. It also avoids issues such as high safety risks, high time/economic costs, narrow working condition coverage, and low label accuracy associated with high-quality engineering dataset collection. This contributes to the application and deployment of deep learning and big data technologies in excavator work state recognition.

Key words: mechanical design and theory, excavator, keypoints estimation, deep learning, synthetic datasets
