Abstract

Disclosed is a display condition analysis device which is capable of analyzing the display conditions of products. This display condition analysis device is provided with: a product recognition means for recognizing, from a display image taken of products on display, the products in the display image; and a display condition analysis means for analyzing, on the basis of the positions of the recognized products, the display conditions of the products on display.

Claims

1. A display condition analysis device comprising:

article recognition unit configured to recognize, from a captured display image of a displayed article, the article in the display image; and

display condition analysis unit configured to analyze a display condition of the displayed article, based on a position of the recognized article.

2. The display condition analysis device according to claim 1, wherein the display condition analysis unit analyzes a display condition of the article based on a distance between a position of the recognized article and a reference position in the display image.

3. The display condition analysis device according to claim 1, wherein the display condition analysis unit analyzes a display condition of the article, based on a degree of separation between a line connecting positions of the respective recognized articles to each other and a comparison reference line in the display image.

4. The display condition analysis device according to claim 1, wherein the display condition analysis unit sets a size of each article recognized from a captured display image of the article displayed at a designated position as a reference state and analyzes a display condition of the article based on a degree of difference between a size of each article in the reference state and a size of the article recognized from a captured display image.

5. The display condition analysis device according to claim 1, wherein the display condition analysis unit sets, as a reference state, a captured display image of an appropriate display state and analyzes a display condition of an article, based on each degree of separation or each degree of difference between a position or a size of each article in the reference state and a position or a size of the article recognized from a captured display image.

6. The display condition analysis device according to claim 1, wherein the display condition analysis unit calculates, as a depth, a separation degree of a position of the recognized article from a suitable position as the article is displayed and analyzes the display condition based on the depth.

7. The display condition analysis device according to claim 6, further comprising analysis result processing unit configured to output an image in a state in which the calculated depth is recognizable.

8. A display condition analysis method comprising, by a display condition analysis device:

recognizing, from a captured display image of a displayed article, the article in the display image, and

analyzing a display condition of the displayed article based on a position of the recognized article.

9. The display condition analysis method according to claim 8, further comprising analyzing a display condition of the article based on a distance between a position of the recognized article and a reference position in the display image.

10. A non-transitory computer-readable program recording medium that records a display condition analysis program causing a computer to execute:

an article recognition process of recognizing, from a captured display image of a displayed article, the article in the display image; and

a display condition analysis process of analyzing a display condition of the displayed article based on a position of the recognized article.

11. The program recording medium according to claim 10, causing a computer to analyze a display condition of the article based on a distance between a position of the recognized article and a reference position in the display image, in the display condition analysis process.
