Abstract: Provided is a device having a machining tool for machining at least one working area of an object. An image-capturing device generated at least one image of the at least one working area and at least one sensor generates sensor data during machining of the at least one working area are arranged on the machining tool. The device also has an evaluation unit which has a computing model that has been trained by way of machine learning on the basis of images of working areas and sensor data by way of which the at least one working area and/or a situation during machining of the at least one working area is able to be identified.

Abstract: In an optical tracking system for determining the position and/or orientation of an object provided with at least one marker (4), having at least two image recording devices (1) for capturing the images of said at least one marker (4) and at least one computing device (2, 3) for evaluating the images captured by said image recording devices (1), it is proposed to provide means for retransferring relevant information that was calculated by a computing device (2, 3) to another computing device (2) and/or to said image recording device (1) for controlling the computing process or the image recording. It is advantageous to retransfer expected values calculated by a prediction device (5). Hereby, a faster and more precise processing of the resulting image data is possible.
