Abstract

A method for generating a point cloud from an image of a scene, the method comprising: obtaining image data representing an image of a scene as captured by an image sensor; generating, based on the image data, an estimated point cloud comprising a plurality of estimated point positions corresponding to features of the scene, by using a machine-learning model trained to estimate point positions from such image data; selecting one or more features of the scene; obtaining, a measured point cloud comprising a plurality of measured point positions measured using electronic distance measurement, said plurality of measured point positions comprising at least respective measured point positions corresponding to the selected one or more features; comparing respective ones of the estimated point positions that correspond to the selected one or more features, and the respective ones of the measured point positions that correspond to the selected one or more features; determining based on the comparison, a transformation that can be applied to the plurality of estimated point positions, such that the respective ones of the estimated point positions more closely align with the respective ones of the measured point positions; and storing the transformation in a computer-readable memory. A further optional method comprises: obtaining second image data representing an image of a scene as captured by an image sensor; generating, based on the second image data, a second estimated point cloud comprising a plurality of estimated point positions corresponding to features of the scene, by using a machine-learning model trained to estimate point positions from such image data; and transforming the second estimated point cloud into a transformed point cloud using the transformation.
