Image Collection System Using Dynamic Background Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Constructing a discriminator for object recognition requires a large number of images for learning and evaluation, consuming significant time and effort.
Innovation Solution
An image collection system that switches and displays multiple first images on a display surface while capturing an object, generating and storing second images for use in learning and evaluation, thereby reducing the time and effort required for discriminator construction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a great number of images for learning and evaluation are prepared manually for each object, then the object recognition accuracy is improved, but the time and effort required for constructing the discriminator increases enormously
Solution Approach 1:
The patent uses a display device to show background images that are copied and used as training data backgrounds. The image capturing apparatus captures images of objects placed on the display, automatically generating training images without manual preparation. This copying approach allows rapid generation of numerous training images with consistent backgrounds, resolving the contradiction between needing many images for accuracy and the time-consuming manual preparation process.
2Adaptability or versatility
If manual work is performed to construct the discriminator using prepared images, then the object identification capability is achieved, but the complexity and effort of the process increases
Solution Approach 1:
The system enables self-service automatic image collection where the display control unit automatically switches background images, the image capturing apparatus automatically captures objects on the display, and the image acquisition unit automatically stores the captured images. This automated self-service process eliminates manual intervention in constructing the discriminator training data, reducing process complexity while maintaining object identification capability.
3Productivity
If multiple images with different contents are displayed and captured simultaneously, then the productivity of image collection is improved, but the complexity of the image collection process increases
Solution Approach 1:
The patent merges multiple functions into an integrated system: the display control unit combines background image switching with object detection, the image capturing apparatus simultaneously captures objects on the display, and the image acquisition unit consolidates storage of captured images. This merging of functions into a coordinated system improves image collection productivity while managing complexity through functional integration rather than separate independent processes.

AI summary
An image collection system includes an image collection apparatus, an image capturing apparatus, and a display. The display includes a display surface that is also used as a placement surface of an object. The image capturing apparatus captures the object placed on the display surface of the display. The image collection apparatus includes a display control unit and an image acquisition unit. The display control unit switches and displays a plurality of first images each having a different content on the display surface of the display when the object is captured. The image acquisition unit acquires a plurality of second images generated by capturing the object on the display surface of the display while the plurality of first images are switched and displayed, and stores the plurality of second images in a storage apparatus.
