Smart Camera Image Buffering for Low-Network Defect Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In production device management systems, image data from smart cameras is large and irreversibly compressed, making it difficult to adjust image processing parameters and analyze defects, leading to increased network costs and decreased data response times due to high communication resource occupancy.
Innovation Solution
An image capturing apparatus that captures images, performs image processing, and accumulates data, transmitting processing results during image capturing periods and storing raw image data during suspension periods, allowing for efficient data management and reduced network load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If image data is transmitted continuously during image capturing periods, then data completeness is improved, but network load and communication costs increase
Solution Approach 1:
The patent segments image data transmission into two distinct phases: during image capturing periods, only image processing results (feature values) are transmitted; during suspension periods, accumulated raw image data is transmitted. This segmentation resolves the contradiction by separating the transmission of processed information (low data volume) from raw data (high data volume), thereby reducing overall network load while ensuring data completeness is maintained through selective transmission.
Solution Approach 2:
The patent implements periodic transmission based on the capturing apparatus's operational cycle. Transmission occurs periodically during suspension periods when the apparatus is not capturing images, utilizing the natural idle periods in the capturing cycle. This periodic action reduces network load by avoiding continuous transmission while ensuring data is transmitted at regular intervals, maintaining data completeness without overwhelming the network.
2Measurement precision
If large amounts of image data are transmitted, then analysis accuracy is improved, but data response time decreases
Solution Approach 1:
The patent accumulates image data in the storage device during suspension periods before transmission. This preliminary accumulation ensures that when data is transmitted, it is ready immediately, reducing data response time. The system prepares data in advance during idle periods, so when transmission or analysis is needed, the data is already available, thereby maintaining both analysis accuracy (complete data) and quick response times.
Solution Approach 2:
The patent extracts and transmits only essential information (image processing results/feature values) during capturing periods, separating this from the full image data. This extraction allows the system to maintain quick response times by transmitting minimal necessary data during active periods, while still enabling accurate analysis by transmitting complete image data during suspension periods when time constraints are less critical.
3Quantity of substance
If image processing results are transmitted instead of raw image data, then network costs are reduced, but defect analysis capability deteriorates
Solution Approach 1:
The patent dynamically adjusts transmission content based on the capturing apparatus's operational state. During capturing periods, only processed results are transmitted; during suspension periods, complete image data is transmitted. This dynamic approach ensures that defect analysis capability is maintained by transmitting full image data when the system is idle, while reducing network costs by transmitting only essential processed information during active periods when bandwidth is more constrained.

AI summary
An image capturing apparatus includes an image capturing portion, a controller to perform image processing to obtain a feature value from image data, and a storage device to accumulate the image data. In an image capturing period of capturing an image of the target object by the image capturing portion, the controller transmits a result of the image processing to a data management server while accumulating the captured image data the storage device, while in an image capturing suspension period of not performing image capturing, the controller transmits the image data accumulated in the storage device to the data management server.
