Abstract
According to an exemplary embodiment of the present disclosure, a method of setting up a work piece based on a vision is present. The method of setting up a work piece based on a vision comprises: calculating a start point of a work piece from the image of a work piece within a vision screen formed by a camera; capturing an image when a tool is captured in the vision screen; and calculating an offset value of the tool from the captured image.
Claims10
A method of working a work piece based on a vision, comprising:
- calculating a reference point of the work piece from an image of the work piece within a vision screen formed by a camera;
- re-setting the calculated reference point as an operation start point;
- and
- performing working according to a preset processing design based on the reset start point as a reference, wherein the performing of the working comprises:
- detecting a position of an end point of a tool when the tool is captured in the vision screen;
- calculating an offset value of the tool by using a distance between the start point of the work piece and the position of the end point of the tool;
- obtaining corrected coordinates of the tool by applying the offset;
- and performing the working based on the re-set start point and the corrected coordinates of the tool.

- re-setting the calculated reference point as an operation start point;
- capturing an image when a tool is captured in the vision screen;
- obtaining corrected mechanical coordinates of the tool by applying an offset calculated by using screen coordinates of the tool calculated from the captured image;
- and
- performing working according to a predefined processing design based on the reset operation start point and the corrected mechanical coordinates, wherein the offset of the tool is calculated by using:
- detecting a position of an end point of the tool;
- calculating a distance between a start point of the work piece and the position of the end point of the tool as pixel displacement coordinates by using the distance per pixel;
- and
- calculating pixel coordinates of the position of the end point of the tool by adding the pixel displacement coordinates to the pixel coordinates of the start point.
