The abnormal part detection unit 314 may display the panoramic image on the display device 330 to be described later after highlighting the detected abnormal part.

The composite unit 315 is a plan view of a solar power plant stored in the storage unit 320 described later, and generates a composite image obtained by superimposing the above-described panoramic image with a plan view having location information of each solar panel. Then, this composite image is displayed on the display device 330 described later.

FIG. 5A shows an abnormal part detection flow by the abnormal part detection system 10 described above.
In step S1, the base data creation unit 311 of the user terminal 300 creates base data.
Specifically, for example, the base data creation unit 311 may divide the location information for each solar panel in the plan view, which is the CAD data shown in FIG. Alternatively, the base data creation unit 311 may add location information for each solar panel to the plan view shown in FIG. 5B and store the plan view in the storage unit 320. When the base data creation unit 311 adds location information to the plan view, a new layer may be added to the plan view, and the location information may be added on the added layer.

Note that the plan view includes images of the markers A to D installed in the solar power plant to be used for superimposing the plan view and the panoramic image.
The markers A to D are made of a material that distinguishes a heat generating portion and a non-heat generating portion, can be recognized from an infrared thermography camera that is the imaging unit 150 of the flying object 100, and can be distinguished by image recognition described later. It has become a shape. It is preferable that the markers A to D have shapes different from each other. For example, the numbers A and D may be shapes. In addition, the markers A to D may be installed on the roof portion of the power conditioner that is always scattered in the solar power plant. 5B shows four markers A to D, but the number of markers is not limited to this. Furthermore, for overlaying the plan view and the panoramic image, it is preferable that three or more markers exist for each panoramic image.
In the plan view, it is not essential to show the shape such as numbers, figures, symbols, and the like indicating the markers as they are. For example, if the marker is “A”, the plan view and the panoramic image can be superimposed if the starting point of the first image of “A” is at an arbitrary point on the plan view.

In step S2, the flying object 100 images the solar panel of the solar power plant from above.
Specifically, as shown in FIG. 5C (a), the flying object 100 sets a specific range to a predetermined range so that any of the markers A to D installed in the solar power plant is always reflected. Interval shooting at intervals.
The captured infrared image is sent from the flying object 100 to the user terminal 300 via the server 200.

  In step S3, as illustrated in (b) and (c) of FIG. 5C, the panorama unit 313 of the user terminal 300 generates a panoramic image from a plurality of infrared images. More specifically, the panorama unit 313 creates an ortho image as a panoramic image after creating a 3D model from a plurality of infrared images.

In step S4, the abnormal part detection unit 314 of the user terminal 300 detects an abnormal part or a hot spot based on the color information of the panoramic image. Specifically, when an abnormal location exists in the solar panel, the temperature of the abnormal location is different from the normal time, so the abnormal location detection unit 314 has color information corresponding to a temperature in a preset range in the panoramic image. Are detected as abnormal locations.
At this time, as indicated by a black square in FIG. 5D, the abnormal part detection unit 314 may display a panoramic image on the display device 330 after highlighting the abnormal part.

In step S5, the composite unit 315 of the user terminal 300 generates a composite image by superimposing the plan view and the panoramic image.
Specifically, the composite unit 315 recognizes both the plan view and the panoramic image markers by image recognition, and as shown in FIG. 5E, the plan view and the panorama are matched so that the contours of both the markers match. By superimposing the image, a composite image as shown in FIG. 5F is generated. Further, the composite unit 315 causes the display device 330 to display the generated composite image.
Note that the composite unit 315 may highlight the abnormal part. In particular, the composite unit 315 identifies the solar panel region by pattern recognition, and omits the abnormal part outside the solar panel area when the part detected as an abnormal part in step S4 is outside the solar panel area. Then, the abnormal part may be highlighted.

In step S6, the abnormal part output unit 316 of the user terminal 300 causes the display device 330 to output the location information of the solar panel in which the abnormal part is detected as shown in FIG. 5G.
Specifically, as described above, when the base data creation unit 311 divides location information for each solar panel in the plan view and stores the location information in the storage unit 320, the abnormal location output unit 316 performs image recognition. Thus, the ID of the solar panel having the abnormal part in the composite image may be acquired, and the storage unit 320 may cause the display device 330 to output the location information associated with this ID. Alternatively, as described above, when the base data creation unit 311 adds location information for each solar panel to the plan view, the abnormal location output unit 316 detects abnormalities in the composite image by image recognition. The location information of the solar panel having the location may be read and output to the display device 330.

[Second Embodiment]

As will be described later, unlike the first embodiment, the second embodiment uses position coordinate information instead of a marker when a plan view and a panoramic image are superimposed. In the following, the differences of the second embodiment from the first embodiment will be mainly described in detail.

An inclination information acquisition unit for acquiring inclination information of the imaging unit;
A correction information acquisition unit for acquiring correction information for correcting distortion of the infrared image;
An angle-of-view information calculation unit that calculates angle-of-view information that is information on the angle of view of the imaging unit after correcting the distortion based on the correction information;
An information adding unit for adding the position coordinate information, the altitude information, the azimuth information, the tilt information, and the angle-of-view information to the infrared image;
A first transmission unit configured to transmit the infrared image to which the position coordinate information, the altitude information, the azimuth information, the tilt information, and the angle-of-view information are added to the server;
The server
A first receiver for receiving the infrared image from the aircraft;
A first storage unit for storing the infrared image;
A second transmission unit that transmits the infrared image stored in the first storage unit to the user terminal;
The user terminal is
A second receiver for receiving the infrared image from the server;
A second storage unit for storing a power plant image obtained by superimposing a map including power plant coordinate information, which is coordinate information of the solar power plant, and a plan view of the solar power plant,
Based on the position coordinate information, the altitude information, the azimuth information, the tilt information, and the angle of view information added to the infrared image, a projection location for projecting the infrared image on the power plant image is provided. A projection position calculation unit for calculating;
Based on the infrared image, an abnormal point detection unit that detects an abnormal point of the solar panel;
By projecting the plurality of infrared images from the projection location onto the power plant image, a composite image in which the power plant image and the plurality of infrared images are superimposed is generated and displayed on a display device. The complex part,
An abnormal part detection system comprising: an abnormal part output unit that outputs location information of a solar panel in which the abnormal part is detected based on the composite image to the display device.
