Abstract
A method for evaluating a laser cut edge of a workpiece includes capturing image data of the laser cut edge and its surroundings, segmenting the image data, and identifying a segment of interest of the image data. The segment of interest comprises image data of the laser cut edge. The method further includes carrying out an image quality detection for the segment of interest and generating, based on the image quality detection, an output for a user.
Claims13
A method for evaluating a laser cut edge of a workpiece, the method comprising:
- A) capturing image data of the laser cut edge and its surroundings, wherein the laser cut edge is formed by laser cutting of the workpiece using a laser cutting machine;
- B) segmenting the image data and identifying a segment of interest of the image data performed by one or more processors, wherein the segment of interest comprises image data of the laser cut edge;
- C) carrying out an image quality detection for the segment of interest performed by the one or more processors, wherein the image quality detection comprises detecting an image sharpness of the segment of interest;
- D) determining by the one or more processors, based on the image quality detection, whether the image sharpness is sufficient;
- E) performing by the one or more processors the following steps:
- upon determining that the image sharpness is not sufficient, generating an output for the user on the output interface, the output recommending recording new image data of the laser cut edge and its surroundings;
- and
- upon determining that the image sharpness is sufficient, evaluating a quality of the laser cut edge based on the image data of the laser cut edge;
- determining at least one method parameter based on the quality of the laser cut edge;
- and
- forwarding the at least one method parameter to a controller for controlling the laser cutting machine to perform laser cutting of further workpieces.
8 more elements
A mobile terminal, comprising:
- a camera configured to capture image data of a laser cut edge with surroundings;
- and
- a communication interface configured to communicate the image data to a computing unit and to receive an output from the computing unit,
- wherein the computing unit comprises one or more processors configured to:
- segment the image data of the laser cut edge with surroundings and identify a segment of interest, wherein the segment of interest comprises image data of the laser cut edge,
- perform an image quality detection by detecting an image sharpness of the segment of interest,
- generate the output indicating whether the image sharpness is sufficient or recommending capturing new image data of the laser cut edge and the surroundings if the image sharpness is not sufficient;
- evaluate a quality of the laser cut edge based on the image data of the laser cut edge upon determining that the image sharpness is sufficient, and
- determine at least one method parameter based on the quality of the laser cut edge;
- wherein the mobile terminal further comprises an output interface to display the output received from the computing unit, and wherein the communication interface is further configured to forward the at least one method parameter to a controller for controlling the laser cutting machine to perform laser cutting of further workpieces.
