Method for Sensor Image Detection and Use of Such a Method in an Electrical Tool

摘要

A method facilitates sensor image detection of a work line that is provided on a workpiece and is to be followed with a working tool of a working device that is equipped with an image detection apparatus. The method includes detecting an image section that is adjacent to the working tool as a halftone image in relation to the working tool applied to the workpiece in a region of the working line, aligning a position of the working device approximately to the working line, and evaluating the halftone image in terms of image pixels describing the working line and lying in contact with and/or overlapping the working line in order to detect the working line.

1. A method for sensor image acquisition of a work line that is provided on a workpiece and is to be tracked by a tool of a working device that is equipped with an image acquisition device, comprising:
acquiring an image section that is adjacent to the tool as a grayscale image with reference to the tool applied to the workpiece in the region of the work line; and in order to acquire the work line, evaluating the grayscale image with regard to image pixels that at least one of:
make contact with the work line; andlie in a fashion overlapping the work line and describe the work line.
