Abstract (en)
[origin: WO2022167298A1] Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for processing images that involves annotation of landmarks on two-dimensional images. In one aspect methods are performed by data processing apparatus for training a device for estimating the relative pose of an imaging device and an object in a two-dimensional image. The methods include identifying a 3D model of the object, identifying landmarks on the 3D model of the object, projecting the 3D model into a collection of two-dimensional images with knowledge of the location of the landmarks from the 3D model on the projection, and training a landmark-detection machine learning model to identify the landmarks in the collection of two-dimensional images. The landmark-detection machine learning model is part of a device for estimating the relative pose of an imaging device.
