A container crane has a trolley movable on a cross-member of a gantry. A harness for picking up and setting down a container and at least one laser scanner are arranged on the trolley. The laser scanner captures a depth image which, as a function of a first and a second angle, indicates the distance of object points detected by a laser beam. The captured depth image is evaluated. Based on the object points, objects are detected and their locations are determined. The objects comprise the harness and/or a container picked up by the harness, and further objects. Based on the detected object points, the contour of the harness and/or of the container picked up by the harness is determined. Detection of further objects within regions defined by the contour is suppressed. A control device takes the detected objects and their locations into account for controlling the container crane.
