An accessory that can be connected to a machine drill is provided. A projector is provided to project a first light spot and a second light spot to a work piece to be processed. A camera is provided to record the first light spot and the second light spot in an image. A processing device is provided to determine an incline of the machine drill in reference to the work piece, based on a first distance of the first light spot from a reference point recorded in the image and a second distance of the second light spot from the reference point recorded in the image. A display device is coupled to the processing device and displays the determined incline. The light spots may be embodied punctual or planar.

Accessory of a machine drill and control method

A drilling apparatus and control method is disclosed. An auxiliary device can be connected to a drilling machine. The auxiliary device includes a camera aligned in a working direction for recording an image of a working surface and a drill hole generated by the drilling machine. An image processing device is provided for identifying the drill hole in the image. Based on a distance from the drill hole to a reference point in the image, an evaluation device determines a distance from the drilling machine to the workpiece. A display device serves to indicate the determined distance.
