Images from ordinary laparoscopes and endoscopes are two dimensional (2D), meaning the surgeon's depth perception is hindered. The proposed method supplements the 2D image with an image of the depth profile of the surface. The depth profile is obtained in real time without surface contact. The profilometer uses the same principle for acquiring distance information as the divergence-ratio axi-vision camera. The profilometer was added to an ordinary laparoscope with minimal increase in the weight and diameter of the shaft. With the profilometer added, there was a significant improvement in the ability to detect minute protrusions.
普通腹腔镜和内窥镜的图像是二维（2D）的，这意味着外科医生的深度感知会受到阻碍。所提出的方法用表面深度轮廓图像来补充二维图像。深度轮廓是在不接触表面的情况下实时获取的。轮廓仪获取距离信息的原理与发散比轴视相机相同。轮廓仪被添加到普通腹腔镜上，轴的重量和直径增加极少。添加轮廓仪后，检测微小突起的能力有了显著提高。
