Abstract: The invention relates to a device comprising: at least one tool module (4) having a quick-coupling interface (19); at least one support having a quick-coupling interface (19) and designed to hold the at least one tool module; and at least one data processing unit designed for computer-assisted tool management. The support for holding the tool module (4) comprises at least one support frame (16), at least one interface (21) for computer-assisted tool module identification, and at least one sensor unit. The support frame comprises at least one quick-coupling interface (19) for a tool module. The tool module comprises at least one implement (18) for use outdoors, at least one suspension that is compatible with the quick-coupling point on the support frame, at least one computer-readable storage medium (22) for computer-readable data, and at least one interface for transmission of computer-readable data.

Abstract: The invention relates to a computer-implemented method for the optical sensing, the detection and the quantification of relevant conditions and/or their changes with respect to at least one target object, wherein at least one target object is temporarily positioned opposite an optical sensor device, and wherein the fault conditions of the fault classes deviate from the optimal condition. The method is characterized particularly in that the background and the target object are distinguished by means of a higher rate of change of the image information of the background in comparison with the rate of change of the image information of the target object.
