Commodity Recognition Apparatus with Image and Barcode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional commodity recognition systems struggle with efficiently recognizing and processing commodities without barcodes, such as loose vegetables and fruits, as they rely primarily on barcode scanning and lack effective methods for image-based recognition.
Innovation Solution
A commodity recognition apparatus equipped with an image capturing unit, a commodity recognition unit, a data code recognition unit, and a switching unit that allows for both barcode and image recognition, enabling the system to automatically identify commodities using image analysis and output the recognized information to a POS terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If barcode scanning is used for commodity recognition, then recognition speed and accuracy are improved for barcoded commodities, but the system cannot recognize commodities without barcodes such as loose vegetables and fruits
Solution Approach 1:
The commodity recognition apparatus integrates multiple recognition functions: barcode recognition unit for scanning barcodes, and image recognition unit for identifying commodities without barcodes through image analysis. The system can automatically switch between these functions based on whether a barcode is detected, making it universally applicable to both barcoded and non-barcoded commodities such as loose vegetables and fruits
2Adaptability or versatility
If a touch panel display is added to allow manual selection of commodities without barcodes, then the system can handle non-barcoded commodities, but the operation complexity and time required for recognition increase
Solution Approach 1:
The image recognition unit automatically captures images of commodities without barcodes and identifies them through pattern recognition algorithms, eliminating the need for manual selection by operators. The system performs self-service recognition by comparing captured images with stored commodity image data, significantly reducing operational complexity and processing time
3Adaptability or versatility
If manual selection through touch panel is required for non-barcoded commodities, then recognition capability is improved, but processing time and operational efficiency deteriorate
Solution Approach 1:
The system replaces the mechanical manual selection process (operator touching the screen to select commodities) with an automated image recognition system. The image capturing unit captures commodity images, the recognition unit processes them through algorithms, and automatically outputs commodity information, substituting manual mechanical operations with automated optical and computational processes that are much faster and more efficient

AI summary
A commodity recognition apparatus comprises a function of recognizing a commodity in an image from the image captured by an image capturing unit, and a function of recognizing a data code attached to the commodity in the image from the image, and can switch these functions by a switching unit. The commodity recognition apparatus outputs the information of the commodity recognized by commodity recognition processing or the information of the data code recognized by data code recognition processing to a POS terminal.
