    • The present disclosure relates to systems, methods, and tools for tool tracking using image-derived data from one or more tool located reference features. A method includes: directing illuminating light from a light source onto a robotic surgical tool within a patient body, wherein the tool includes a plurality of primitive features having known positions on the tool, and wherein each feature includes a spherical reflective surface; capturing stereo images of the plurality of primitive features when the tool is within the patient body, wherein the stereo images are captured by an image capture device adjacent the illumination source so that the illumination light reflected from the imaged primitive features toward the image capture device substantially aligns with spherical centers of the surfaces of the imaged primitive features, and determining a position for the tool by processing the stereo images so as to locate the spherical centers of the imaged primitive features by using the reflected light.
    • 本公开涉及使用来自一个或多个位于工具的参考特征的图像衍生数据进行工具跟踪的系统,方法和工具。 一种方法包括:将来自光源的照明光引导到患者体内的机器人手术工具上,其中所述工具包括在所述工具上具有已知位置的多个原始特征,并且其中每个特征包括球形反射表面; 当所述工具在所述患者体内时,捕获所述多个基本特征的立体图像,其中所述立体图像由邻近所述照明源的图像捕获装置捕获,使得从所述成像原图反射的照明光特征朝向所述图像捕获装置基本上 与成像原始特征的表面的球面中心对齐,并且通过处理立体图像来确定工具的位置,以便通过使用反射光定位成像原始特征的球面中心。
