机器人辅助微创手术 (MIS) 的使用不断增加，为使用增强现实 (AR) 进行图像引导手术提供了理想的环境。 AR 的无缝合成取决于与虚拟对象出现以及与真实环境进行视觉交互的方式相关的许多因素。传统的叠加 AR 方法通常会损失深度感知。本文提出了一种用于机器人辅助 MIS 的新 AR 方法，该方法使用一种新颖的基于 pq 空间的非真实感渲染技术，提供嵌入式虚拟对象的透视视觉，同时保持暴露解剖表面的显着解剖细节。体模和体内肺叶切除数据的实验结果证明了所提出的方法所实现的视觉真实感及其在提供高保真 AR 深度感知方面的准确性。
The increasing use of robotic assisted minimally invasive surgery (MIS) provides an ideal environment for using Augmented Reality (AR) for performing image guided surgery. Seamless synthesis of AR depends on a number of factors relating to the way in which virtual objects appear and visually interact with a real environment. Traditional overlaid AR approaches generally suffer from a loss of depth perception. This paper presents a new AR method for robotic assisted MIS, which uses a novel pq-space based non-photorealistic rendering technique for providing see-through vision of the embedded virtual object whilst maintaining salient anatomical details of the exposed anatomical surface. Experimental results with both phantom and in vivo lung lobectomy data demonstrate the visual realism achieved for the proposed method and its accuracy in providing high fidelity AR depth perception.
