METHOD FOR OPERATING AN INDUSTRIAL TRUCK IN A WAREHOUSE AND INDUSTRIAL TRUCK

Method for operating a materials handling vehicle (10) in a warehouse, wherein the materials handling vehicle comprises a camera (14) which is arranged at a fixed height on the materials handling vehicle, and the method comprises the following steps: · Capturing a sequence of two-dimensional images with the camera (14), · Computing a three-dimensional point cloud based on the sequence of two-dimensional images, · Computing a scaling factor for the point cloud based on a first point of the point cloud and a second point of the point cloud, which each represent a defined position in space, · Providing a scaled, three-dimensional point cloud (22) which represents an environment of the materials handling vehicle (10) in the warehouse, and · Continuously computing a current position of the materials handling vehicle (10) in space based on a current position of the camera (14), which is determined using current two-dimensional images and the scaled, three-dimensional point cloud (22), · Evaluating the current position of the materials handling vehicle (10) for navigation in the warehouse and/or for collision avoidance.
