All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1-3 show a first embodiment of a method for monitoring a utility pole of the present invention.
The utility pole monitoring method in this embodiment includes the following steps:
step S101: shooting is performed in a preset direction using a satellite to obtain an SAR image, and the utility pole 10 is identified from the SAR image. It will be appreciated that shooting the satellite in different directions will result in different SAR images including the pole 10, vegetation, field, house or mountain. In step S101, the utility pole 10, a vegetation, a field, a house, or a mountain is identified from the SAR image, and the utility pole 10 is proposed.
Further, in step S101, the step of identifying the utility pole from the SAR image includes: a1, judging whether a strip-shaped and cylindrical wire rod exists in the SAR image; and step A2, if yes, the line pole is determined to be a line pole. It is understood that the line pole is long and cylindrical, and thus whether there is a utility pole can be determined by determining whether there is a long and cylindrical pole in the SAR image.
Step S102: it is determined whether the pole 10 is tilted. It will be appreciated that the utility pole 10 is normally vertically disposed, thus indicating a problem with the utility pole 10 when the utility pole 10 is tilted requiring timely maintenance. And the utility pole 10 can be inclined only when the utility pole collapses and is influenced by typhoon or lightning disaster weather.
As shown in fig. 2, step S102 includes the following sub-steps:
step S1021: and (3) analyzing the projection length a of the telegraph pole 10 projected on the ground from the SAR image. It is understood that, in step S1021, the SAR image is used to analyze that the projection length a of the utility pole 10 projected on the ground is not the length of the utility pole 10 actually projected on the ground, and the projection length a is proportional to the actual length of the utility pole 10 projected on the ground, so that the actual length of the utility pole 10 projected on the ground can be calculated from the SAR image by using the projection length a. That is, the SAR image is provided with a length scale, and the real length of the utility pole 10 projected on the ground can be calculated by the projected length a and the length scale.
Step S1022: and acquiring the preset length of the telegraph pole 10 projected on the ground corresponding to the longitude and latitude. It can be understood that, when the satellite shoots in the preset direction to obtain the SAR image, the longitude and latitude of the utility pole 10 in the SAR image are known, so the preset length of the utility pole 10 projected on the ground under the normal condition is also known, and thus the longitude and latitude and the preset length of the utility pole 10 can be directly obtained.

That is, the latitude and longitude of each utility pole 10 is determined, and the preset length of the utility pole 10 projected on the ground under normal conditions is determined.
Step S1023: and judging whether the projection length a is the same as the preset length. If the projection length a is determined to be different from the preset length, step S1024 is performed: the utility pole 10 is judged to be inclined. If it is determined that the projection length a is the same as the preset length, it returns to step S1021. It is understood that the projected length a is different from the preset length if the utility pole 10 is tilted, and is the same as or slightly different from the preset length if the utility pole 10 is normal without being tilted.
