Description

Technical Field

[0001] The utility model relates to the technical field of power transmission line detection devices, and in particular to a high-precision power transmission line detection device based on machine vision. Background Art

[0002] Transmission lines are exposed to the wild for a long time. Under the influence of natural weather conditions and their own continuous mechanical tension, transmission lines may have defects such as broken strands, corrosion, and cracks, which requires regular inspection operations.

[0003] Patent document with application number CN217766142U discloses a high-precision detection device for overhead transmission lines based on machine vision.

[0004] It includes an inspection robot body, a mechanical arm and a transmission line visual collection mechanism. The base of the mechanical arm is fixed on the inspection robot body. The transmission line visual collection mechanism consists of a semi-enclosed C-shaped collection cavity and a plurality of arc-shaped light sources and a plurality of cameras arranged on the semi-enclosed C-shaped collection cavity. The free end of the mechanical arm is connected to the semi-enclosed C-shaped collection cavity. The plurality of arc-shaped light sources are distributed along the inner wall of the semi-enclosed C-shaped collection cavity at intervals. The plurality of cameras are distributed along the outer wall of the semi-enclosed C-shaped collection cavity at intervals. The lenses of the plurality of cameras face inwards. One camera corresponds to one arc-shaped light source. Each arc-shaped light source is provided with a visual collection opening corresponding to the camera lens.

Therefore, it is not conducive to practical application and operation. To address the above problems, we have introduced a high-precision transmission line detection device based on machine vision.
