There is a condition that “there is each vertex on a plane that is perpendicular to the ground and is horizontal to the direction of the solar panel 1”, and “there is each vertex on a plane that is perpendicular to the ground, and four vertices are A condition such as “rectangular” is acquired. The condition may be only one type, or may be selected from several options on the input screen, for example.

  Then, the observation distance calculation unit 283 acquires the distance to one point among the vertices of the target location 2 acquired by the one observation distance acquisition unit 281, the condition acquired by the condition acquisition unit 282, and the observation direction acquisition Based on the observation direction acquired by the unit 27, the distance from the reference position to each vertex of the target location 2 is calculated. Note that the calculation method and the calculation formula are contents that can be realized by using an existing technique, and thus detailed description thereof is omitted here.

  Then, the target shape acquisition unit 29 is based on the inclination and orientation from the reference position acquired by the observation direction acquisition unit 27 to the target location 2 and the distance from the reference position acquired by the observation distance acquisition unit 28 to the target location. The shape of the target location 2 is acquired. Specifically, by managing the observation direction acquired by the observation direction acquisition unit 27 and the observation distance acquired by the observation distance acquisition unit 28 for each vertex constituting the polygon of the target location 2, that is, the direction The shape of the target location 2 is acquired by managing a plurality of points having a distance.

Here, the difference in the principle of acquiring the shape of the target location 2 between the target shape acquisition unit 26 in the second embodiment and the target shape acquisition unit 29 in the third embodiment will be described with reference to FIG.
FIG. 9 is a schematic explanatory diagram illustrating a difference in principle between the target shape acquisition unit 26 in the second embodiment and the target shape acquisition unit 29 in the third embodiment to acquire the shape of the target location 2.

  As shown in FIG. 9 (a), in the second embodiment, the direction and distance from the reference position are measured only for the observation point that is the central point of the target location 2 in the first embodiment. Measure the direction and distance from the reference position (here, the position indicated by the double circle in the figure is the reference position) for each vertex (a plurality of points) constituting the target location 2, and determine the direction and distance. It manages multiple points.

  On the other hand, in the third embodiment, as shown in FIG. 9B, the orientation is not the orientation from the reference position to a certain point, but the orientation of the camera at the time of shooting, and the distance is Measure only the distance from the reference position (here, the position indicated by the double circle in the figure is the reference position) to a vertex (point P in the example of FIG. 9B) The direction of each vertex of the location 2 is obtained from the photograph taken.

  Since the input screen and the output screen in the third embodiment are the same as those in the first embodiment shown in FIGS. 4A and 4C, the illustration and description are omitted. . Since the following processing flow is the same as that in the second embodiment, a flowchart illustrating an example of the operation of the reflected light damage check apparatus 300 in the third embodiment is also omitted.

  Then, the calculation unit 150 includes the panel size acquisition unit 11, the panel orientation acquisition unit 12, the reference position acquisition unit 21, the observation direction acquisition unit 27, the observation distance acquisition unit 28, the target shape acquisition unit 29, and the latitude / longitude acquisition unit 30. Reflection of whether or not the reflected light from the solar panel 1 is inserted into the target location 2 using the information acquired by each of them, that is, using various information acquired by the information acquisition unit 240 of the reflected light pollution check device 300. The presence / absence of light incidence and the date and time (date and time) when the reflected light enters the target location 2 are calculated, and the output unit 60 calculates the result (that is, the presence / absence of reflected light incidence at the target location 2 and the reflected light) 4 is output as a display screen as shown in FIG. 4C, for example. Thereby, it can be grasped in advance whether there is a risk of trouble occurring when a solar panel is installed in the place.

  As described above, according to the reflected light pollution check device 300 according to the second embodiment of the present invention, similar to the reflected light pollution check devices 100 and 200 according to the first and second embodiments, the vicinity of the solar panel is installed. It is possible to accurately check in a short time before installing the solar panel whether there is light pollution due to the reflected light from the solar panel being inserted into adjacent places (target places) such as windows and balconies of the house You can install the solar panel with peace of mind, without worrying about removing it after it has been installed or taking a trial.

  In the first to third embodiments, the information acquisition units 40, 140, and 240 may further include a sky information acquisition unit. This is because, for example, the reflected light pollution check device 100, 200, 300 includes a fisheye lens, so that the sky above the place where the solar panel 1 is installed is photographed and the surroundings block sunlight and reflected light. The sky information of whether or not is acquired. Thus, by acquiring sky information, it is possible to calculate more accurately whether or not the reflected light from the solar panel 1 is inserted into an adjacent location (target location 2).

  Moreover, in the above-mentioned embodiment, although it was set as the reflected light damage check apparatus which can estimate about the reflected light damage of the sunlight by a solar panel, it is not restricted to a solar panel, but by the glass surface of buildings, such as a building It is also possible to apply to sunlight reflected light pollution.

  In the above-described embodiment, the reflected light pollution check devices 100, 200, and 300 have been described as fixed hardware. However, the present invention is not limited to this, and is mounted on a device such as a personal computer or a smartphone. It goes without saying that the same processing may be performed as application software for checking light pollution caused by reflected light in the solar panel.

  In the present invention, within the scope of the invention, any combination of the embodiments, or any modification of any component in each embodiment, or omission of any component in each embodiment is possible. .
