Monitoring device, monitoring method, and program

Claims

1. A registration means that registers as a basic area an area in which a predetermined part of a display shelf is captured in a basic image captured by an imaging means in the basic state, or an area in which products displayed on the display shelf are captured. If the area in which a predetermined portion of the display shelf is captured is registered as the basic area, the detection means detects the area in which the products displayed on the display shelf are captured as the comparison area from the image to be processed captured by the imaging means, and if the area in which the products displayed on the display shelf are captured is registered as the basic area, the detection means detects the area in which a predetermined portion of the display shelf is captured as the comparison area from the image to be processed, A determination means for determining a change in the state of the imaging means based on the relative positional relationship between the basic region and the comparison target region, A monitoring device having the following features.

2. The determination means is, The monitoring device according to claim 1, which determines a change in the state of the imaging means based on whether or not there is an overlap between the basic area and the comparison target area, and at least one of the degree of overlap between the basic area and the comparison target area.

3. The determination means is, The monitoring device according to claim 2, which determines that there has been a change in the state of the imaging means when the basic area and the comparison area overlap.

4. The determination means is, The monitoring device according to claim 2, which determines that there has been a change in the state of the imaging means when a predetermined percentage or more of the area of ​​the comparison target area overlaps with the basic area.

5. The determination means is, A monitoring device according to any one of claims 1 to 4, which determines the degree of change in the state of the imaging means and performs corresponding processing according to the determined degree of change.

6. One or more computers, In the basic image captured by the imaging means in the basic state, the area in which a predetermined part of the display shelf is captured, or the area in which the products displayed on the display shelf are captured, is registered as the basic area. If the area in which a predetermined portion of the display shelf is captured is registered as the basic area, the area in which the products displayed on the display shelf are captured is detected as the comparison area from the image to be processed captured by the imaging means, and if the area in which the products displayed on the display shelf are captured is registered as the basic area, the area in which a predetermined portion of the display shelf is captured is detected as the comparison area from the image to be processed, A monitoring method for determining a change in the state of the imaging means based on the relative positional relationship between the basic area and the comparison area.

7. Computers, A registration means for registering as a basic area an area in which a predetermined part of a display shelf is captured in a basic image captured by an imaging means in the basic state, or an area in which products displayed on the display shelf are captured. If the area in which a predetermined portion of the display shelf is captured is registered as the basic area, the detection means detects the area in which the products displayed on the display shelf are captured as the comparison area from the image to be processed captured by the imaging means, and if the area in which the products displayed on the display shelf are captured is registered as the basic area, the detection means detects the area in which a predetermined portion of the display shelf is captured as the comparison area from the image to be processed, A determination means that determines a change in the state of the imaging means based on the relative positional relationship between the basic area and the comparison area. A program that makes it function as such.

8. A registration means that registers the area in which the product is detected from the basic image captured by the basic state imaging means as the basic area, A detection means for detecting, from the image to be processed captured by the imaging means, the region in which the product is visible as the comparison region, A determination means for determining a change in the state of the imaging means based on the comparison result between the basic area and the comparison target area, A monitoring device having the following features.

9. One or more computers, The imaging means in the basic state registers the area in which the detected product is visible from the basic image captured as the basic area. From the image to be processed captured by the imaging means, the region in which the product is visible is detected as the comparison region. A monitoring method for determining a change in the state of the imaging means based on the comparison result between the basic area and the comparison target area.

10. Computers, A registration means that registers the area in which the product is detected from the basic image captured by the basic state imaging means as the basic area. A detection means that detects the area in which the product is visible from the image to be processed captured by the imaging means as a comparison area. A determination means that determines a change in the state of the imaging means based on the comparison result between the basic area and the comparison target area. A program that makes it function as such.
