Laser Processing Start Point Calculation via Image Coordinate Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In laser processing, the coordinates on the X-axis and Y-axis for determining the starting point are typically manually measured and recalibrated repeatedly, which reduces processing efficiency and degrades user experience.
Innovation Solution
A method and device for calculating the starting point by establishing a first coordinate system for a picture of the part to be processed and a second coordinate system, where the first coordinate of a light spot is obtained in the first coordinate system and converted to a second coordinate in the second coordinate system, allowing for automated determination of the starting point without manual measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual measurement and recalibration are used to determine starting point coordinates, then measurement precision can be achieved, but productivity decreases due to repeated manual operations
Solution Approach 1:
The patent replaces manual mechanical measurement operations with an automated optical measurement system. A camera captures images of the workpiece, and image processing algorithms automatically calculate the starting point coordinates, eliminating the need for repeated manual measurement and recalibration while maintaining measurement precision.
Solution Approach 2:
The system enables self-service automation where the device automatically determines starting point coordinates through image capture and processing. The automated calculation system performs measurements without human intervention, allowing the device to serve itself in determining processing parameters, thereby improving productivity.
2Measurement precision
If manual measurement and recalibration are performed repeatedly, then starting point accuracy can be maintained, but loss of time increases due to frequent recalibration
Solution Approach 1:
The patent substitutes manual recalibration operations with automated image-based measurement. The camera captures workpiece images and the system automatically calculates coordinates, eliminating time-consuming manual recalibration while maintaining accuracy through consistent automated measurement processes.
Solution Approach 2:
The system performs preliminary automated measurement and coordinate calculation before processing begins. By pre-determining starting point coordinates through automatic image processing, the system eliminates the need for repeated recalibration during operation, saving time while maintaining measurement precision.

AI summary
A method for calculating a starting point includes the following. A first coordinate system and a second coordinate system are established. The first coordinate system includes a CX-axis and is a coordinate system for a picture of a part to be processed. The picture of the part to be processed is captured. A first coordinate of a light spot on the CX-axis is obtained based on the picture. The light spot is formed by irradiating on the part to be processed by light. The second coordinate of the light spot in the second coordinate system is calculated based on the first coordinate as the starting point for processing. The method further relates to a device for laser processing and a non-transitory computer-readable storage medium.
