1. A method comprising: facilitating three-dimensional visual servoing for positioning a robot in an environment, the facilitating comprising: obtaining three-dimensional point cloud data of a scene of the environment, the scene including a feature; converting the three-dimensional point cloud data into a two-dimensional image, including projecting a plurality of points of the point cloud data onto a common plane and determining a plurality of image values for the plurality of points, each image value of the plurality of image values being for a respective point of the plurality of points, and each image value indicating a distance value for the point relative to the common plane; identifying based on the two-dimensional image a three-dimensional position of the feature; and providing an indication of the identified three-dimensional position of the feature to a controller for positioning the robot.
