  • IMAGING SYSTEM
    Publication number: 20210233276
    Abstract: An imaging system comprises at least three cameras having a common field of view, wherein each of the at least three cameras having a camera centre, and wherein the camera centres are positioned along a line, the at least three cameras being configured to: image a calibration object to generate a set of calibration object images, wherein the calibration object is located nearby the at least three cameras and in the common field of view, and image a scene comprising a set of distant scene position points to generate a set of position point images, and a processing unit configured to generate a set of calibration parameters in dependence on the set of calibration object images and the set of position point images.

  • METHOD AND SYSTEM FOR LOCATING A POSITION OF A MOVABLE DEVICE
    Publication number: 20190297592
    Abstract: A method in a movable device for locating or positioning of the movable device within an environment comprises: receiving, from an external unit, a central environment model; determining distance-dependent measurements for one or more positions of the movable device; determining a location of the movable device based on the received central environment model and the determined distance-dependent measurements, said determining comprising: forming a local environment model defining estimated locations of the wireless transmission sources and of the one or more positions of the movable device, wherein the estimated locations of the wireless transmission sources in the local environment model are updated in relation to the central environment model, wherein the updated estimated locations of the wireless transmission sources and the estimated locations of the one or more positions of the movable device are set based on a calculated error of the local environment model in relation to the determined distance-depend
