  • Publication number: 20240181625
    Abstract: A method of localizing a mobile construction robot on a construction site, wherein environment data of the construction site is captured, wherein a pose of the mobile robot is inferred using the environment data disclosed, wherein the method comprises a step of semantic segmentation, wherein a semantic classifier having an updatable semantic model classifies the environment data into at least two semantic classes, wherein the semantic model is updated at least once. Furthermore, the invention concerns a mobile construction robot system and a computer program product. The invention provides solutions for a robust and precise localization of the mobile construction robot.

  • Patent number: 11295162
    Abstract: An approach to place recognition from an image makes use of the detection of objects at a set of known places as well as at an unknown place. Images of the detected objects in an image of the unknown place are processed to yield respective numerical descriptors, and these descriptors are used to compare the unknown place to the known places to recognize the unknown place. At least some embodiments make use of a trained parameterized image processor to transform an image of an object to an object descriptor, and the training of the processor is meant to preserve distinctions between different instances of a type of object, as well as distinctions between entirely different types of objects.
