Abstract
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.
