Robotic scrub nurses have the potential to become an attractive solution for the operating room. Surgical instrument detection is a fundamental task for these systems, which is the focus of this work. We address the detection of the complete surgery set for wisdom teeth extraction, and propose a data augmentation technique tailored for this task.
Using a robotic scrub nurse system, we create a dataset of 369 unique multi-instrument images with manual annotations. We then propose the Mask-Based Object Insertion method, capable of automatically generating a large amount of synthetic images. By using both real and artificial data, different Mask R-CNN models are trained and evaluated.
Our experiments reveal that models trained on the synthetic data created with our method achieve comparable performance to that of models trained on real images. Moreover, we demonstrate that the combination of real and our artificial data can lead to a superior level of generalization.
The proposed data augmentation technique is capable of dramatically reducing the labelling work required for training a deep-learning-based detection algorithm. A dataset for the complete instrument set for wisdom teeth extraction is made available for the scientific community, as well as the raw information required for the generation of the synthetic data ( https://github.com/Jorebs/Deep-learning-based-instrument-detection-for-intra operative-robotic-assistance ).
机器人手术助手有潜力成为手术室的一个有吸引力的解决方案。手术器械检测是这些系统的基本任务,这也是本工作的重点。我们针对智齿拔除手术的全套手术器械检测进行研究,并提出了一种针对该任务的专用数据扩充技术。
我们使用机器人手术助手系统创建了一个包含 369 张独特多器械图像的数据集,并进行了手动标注。然后,我们提出了基于掩模的物体插入方法,可以自动生成大量的合成图像。通过使用真实数据和人工数据,我们训练和评估了不同的 Mask R-CNN 模型。
我们的实验表明,使用我们的方法生成的合成数据训练的模型与使用真实图像训练的模型具有相当的性能。此外,我们还证明了真实数据和我们的人工数据的结合可以实现更优的泛化能力。
所提出的数据扩充技术能够显著减少训练基于深度学习的检测算法所需的标注工作。我们为科学界提供了一个完整的智齿拔除手术器械数据集,以及生成合成数据所需的原始信息(https://github.com/Jorebs/Deep-learning-based-instrument-detection-for-intra-operative-robotic-assistance)。
