The invention relates to a device and a method for an unmanned flying object, in particular for a drone. According to the invention, sensor data (21) of at least one imaging sensor (16A - 16D) and at least one distance-detecting sensor (12A - 12D) is received by a sensor interface (18) and supplied to a signal processing unit (20) which is designed to detect at least one specified object and/or differentiate said at least one specified object from other objects and to determine the parameters of the detected or differentiated object by comparing the sensor data (21) with reference data (25). The parameters of the specified object are then output by an output interface (29).
