Mounting Apparatus Super-Resolution Region Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In super-resolution processing for mounting devices, setting a sufficient processing region to account for deviations in electronic component position or angle leads to unnecessary processing time due to inclusion of non-essential areas.
Innovation Solution
The mounting device captures mark images and low-resolution images under different conditions, allowing for a targeted processing region to be set based on the electronic component's position, thereby limiting the processing area to what is necessary for accurate positioning and angle determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a processing region with a predetermined margin is set to include the electronic component even when deviated, then the electronic component position and angle can be accurately obtained, but the processing time becomes longer due to unnecessary areas being processed
Solution Approach 1:
The patent applies local quality by performing super-resolution processing only on a specifically determined processing region that includes the electronic component, rather than on the entire captured image. The control device determines this processing region based on the captured image data, and the image processing device selectively applies super-resolution processing only to this region. This localized approach maintains measurement precision for the component while reducing unnecessary processing of surrounding areas, thereby resolving the contradiction between accurate position/angle measurement and processing time efficiency.
2Reliability
If the processing region is set with a sufficient margin to account for position or angle deviation, then the electronic component is included even when deviated, but the processing region becomes larger than necessary
Solution Approach 1:
The patent implements dynamics by making the processing region adaptable rather than fixed. The control device determines the processing region dynamically based on the actual captured image data and the specific electronic component being processed. This allows the processing region to be optimized for each component's actual position and size, ensuring reliable inclusion of the component while minimizing the processing area. The region adjusts to the component's actual boundaries rather than using a static margin-based approach.

AI summary
A mounting device sets a processing region for super-resolution processing based on an approximate position of a main body portion of a component 60 included in a mark image for use in obtaining a position of a fiducial mark and then performs super-resolution processing. Thus, the processing region for super-resolution processing can be appropriately set and prevented from becoming larger than necessary with respect to the main body portion of the component 60. Further, the processing region for super-resolution processing is determined using the mark image captured under an imaging condition different from that for the component image for use in super-resolution processing. Thus, the processing region can be appropriately set while the component image is kept under an imaging condition suitable for super-resolution processing. Therefore, the processing region for performing super-resolution processing can be set more appropriately, and the super-resolution processing can be efficiently performed.
