An industrial truck configured to carry a load and having an autonomous/assisted driving function for approaching an apparatus configured to interact with the industrial truck for performing loading/unloading operations of the truck, the industrial truck comprising: - a control unit configured for controlling the autonomous/assisted driving function; - at least a camera configured to capture images of an environment of the industrial truck, the at least one camera being connected to the control unit for providing the control unit with an image signal related to the captured images; whereby the control unit is configured to detect, based on the image signal, an optical marker (30, 31) in the environment, wherein the control unit is configured to determine a relative position of the industrial truck with respect to the detected marker based on the image signal, whereby the control unit is further configured to acquire information related to the optical marker, the information defining a target position (51, 52) to be reached by the industrial truck relative to the optical marker for performing the loading/unloading operations, wherein the control unit is further configured to control the autonomous/assisted driving function based on the determined relative position of the industrial truck with respect to the detected optical marker and on the information related to the optical marker, in order to reach the target position, characterised in that the control unit is configured to perform, based on the image signal provided by the camera, an object recognition function to recognize at least a part of the apparatus configured to interact with the industrial truck for loading and unloading the truck, wherein the control unit is configured to preferentially attempt to detect the optical marker in a portion of the image captured by the camera that is determined based on the recognition of the at least a part of apparatus by means of the object recognition function. - a control unit configured for controlling the autonomous/assisted driving function; - at least a camera configured to capture images of an environment of the industrial truck, the at least one camera being connected to the control unit for providing the control unit with an image signal related to the captured images; whereby the control unit is configured to detect, based on the image signal, an optical marker (30, 31) in the environment, wherein the control unit is configured to determine a relative position of the industrial truck with respect to the detected marker based on the image signal, whereby the control unit is further configured to acquire information related to the optical marker, the information defining a target position (51, 52) to be reached by the industrial truck relative to the optical marker for performing the loading/unloading operations, wherein the control unit is further configured to control the autonomous/assisted driving function based on the determined relative position of the industrial truck with respect to the detected optical marker and on the information related to the optical marker, in order to reach the target position, characterised in that the control unit is configured to perform, based on the image signal provided by the camera, an object recognition function to recognize at least a part of the apparatus configured to interact with the industrial truck for loading and unloading the truck, wherein the control unit is configured to preferentially attempt to detect the optical marker in a portion of the image captured by the camera that is determined based on the recognition of the at least a part of apparatus by means of the object recognition function.
