Surface Inspection Position Calibration Using Shared Index Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing object inspection systems face challenges in sharing inspection parameters and image data among multiple devices, leading to inconsistencies in inspection positions and reduced efficiency in surface inspection processes.
Innovation Solution
The system employs a network of object inspection devices with cameras and robots, using an index object with reference points to calibrate and adjust inspection positions across devices, enabling precise alignment and data sharing for consistent surface inspections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple object inspection devices are used to inspect surfaces, then inspection coverage and productivity are improved, but inconsistencies in inspection positions and difficulty in sharing inspection parameters occur
Solution Approach 1:
An index object with reference points is introduced as an intermediary between multiple inspection devices. Each device images the index to obtain coordinate data, which serves as a common reference for calibrating and adjusting inspection positions across different devices, enabling consistent measurements despite physical separation
Solution Approach 2:
The index object creates a standardized coordinate reference that can be copied and shared among multiple inspection devices. By imaging the same index and exchanging coordinate data, each device obtains a replicated reference framework that ensures consistent inspection positions across the network
2Productivity
If inspection parameters are shared among multiple devices, then efficiency is improved, but device complexity and coordination requirements increase
Solution Approach 1:
Each inspection device autonomously images the index object and independently calculates its own coordinate data and inspection position adjustments. This self-service approach allows parameter sharing without requiring complex centralized coordination, as each device automatically adapts its parameters based on the shared index reference

AI summary
An object inspection device capable of sharing an image or an inspection parameter for surface inspection of an object to be inspected among a plurality of object inspection devices. The object inspection device includes a camera, a robot relatively positioning the object and the camera, an index, and a controller controlling the camera and the robot. The controller is configured to control the robot to position the index and the camera at any relative position, cause the camera to image the index to acquire imaged data of the index, hold the robot at a position where the index is disposed at an index reference point in the image coordinate system based on the imaged data and coordinate data of the index reference point, and adjust an inspection position using the position of the robot at this time.
