Description

Technical Field

[0001] The present invention relates to a used item appraisal system for analyzing the condition from captured images of used items using a mobile terminal such as a smartphone and calculating an appropriate purchase price.

Background Art

[0002] In recent years, against the backdrop of the effective utilization of resources and the growing awareness of reuse, online appraisals of used items via the Internet and person-to-person (CtoC) trading platforms such as flea market apps have rapidly spread. Generally, in the business of appraising used items, the mainstream method is that a user transmits images of the appearance of the used item captured from multiple angles to a server, and an appraiser of a purchasing merchant visually checks the images to determine the presence or absence of scratches and the wear condition, and presents the final appraisal amount.

[0003] In addition, with the remarkable improvement of image recognition technologies such as deep learning (deep neural networks) in recent years, a system has been proposed that uses AI (artificial intelligence) to automatically detect defects such as scratches, dirt, and dents from images of used items and perform a simple appraisal by comparing with market price information on a database. Thanks to these automation technologies, even ordinary users without specialized appraisal knowledge can relatively easily grasp the approximate value of used items from home without visiting a store.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the conventional automatic appraisal system using image recognition, there were several serious problems in practical operation as follows. For example, even if image analysis can simply detect a "scratch," the actual reduction in market value will vary greatly depending on the physical location of the scratch ("where it is on the product") and its qualitative attributes ("what kind of scratch it is, whether it's a minor surface scuff or a deep cut that penetrates the material, etc."). Conventional systems lacked sufficient logic to comprehensively evaluate these detailed defect attributes and reflect them in the price, often resulting in a significant discrepancy between the system's results and the precise appraisals performed by skilled professional appraisers.

[0005] Furthermore, there were challenges in calculating the value when multiple defects were located in a small area. For example, if there were many minute scratches clustered in very close proximity, simply counting them as individual defects and adding them up could result in an excessively large deduction that was not actually appropriate. On the other hand, if each scratch was treated as "minor" and given a low value individually, the damage as widespread and significant cosmetic deterioration (so-called surface scratches) could not be properly reflected in the evaluation, potentially leading to a decrease in assessment accuracy.

[0006] Furthermore, there was concern that the total deductions based on individual defects might exceed the "parts replacement costs" or "overhaul costs" required to fundamentally resolve those defects, resulting in an economically irrational assessment. In addition, because the calculation process was a black box, users lacked clarity on the specific basis for the calculation and the reasons for the deductions, making it difficult for them to accept the offered amount.

[0007] This invention was made to solve the aforementioned problems, and goes beyond mere detection of the condition of used goods to perform a precise, multifaceted analysis at the attribute level. The aim is to provide a used goods appraisal system that can quickly and automatically calculate rational, objective, and highly accurate appraisal results in accordance with the judgment criteria of professional appraisers. [Means for solving the problem]

[0008] This invention has an interface, memory, and CPU, and the interface receives images of used goods captured by a camera. The CPU is a used goods appraisal system that performs the following processes: writing images of used goods received by the interface to the scale; identifying the type of used goods based on the images of used goods read from the memory; identifying defects in the used goods based on the images of used goods and the identified type; and generating appraisal data indicating the purchase price of the used goods based on the identified type of used goods and the identified defects. [Effects of the Invention]

[0009] According to this invention, defects in used goods are evaluated from multiple perspectives based on several attributes such as location, type, and size, thereby achieving a high level of accuracy similar to that of an expert appraiser. Furthermore, by incorporating a cap function that limits the cost of parts replacement to an upper limit, it becomes possible to calculate prices in an economically rational manner, preventing excessive deductions. In addition, since the basis for price deductions according to the defects can be clearly presented, it can increase user satisfaction and improve the transparency of used goods transactions. [Brief explanation of the drawing]
