Embodiment

[0037] Example: such as Figure 1-Figure 3As shown, an autonomous scanning method for power transmission towers based on the hovering state of the aircraft includes the following steps:

[0038] The first step, offline deep learning: For the original image with labels, the training of the tower recognition model and the multi-target detection model are carried out respectively. Both trainings use a deep convolutional neural network. The image data of labels and background labels, the input data for multi-target detection model training is image data with various power component labels and background labels;

[0039] The second step, online autonomous scanning: Obtain the tower identification model through step 1), combine the tower area and tower POS information, and obtain the autonomous scanning route of the transmission tower under manual intervention;

[0040] The third step, online automatic high-definition imaging: through step 1), the multi-target recognition model of ...

Abstract

The invention discloses an autonomous scanning method for transmission poles and towers based on the hovering state of an aircraft, which includes an offline deep learning step, an online autonomous scanning step and an online automatic high-definition imaging step. Tower area information and POS information feedback control pod to realize autonomous scanning of transmission towers, use deep convolutional neural network to automatically learn and describe the inherent multi-level features of various power components and abstract them level by level, so as to realize feature learning and classification at the same time The purpose of detection is to effectively solve the problem that the traditional feature extraction method is difficult to achieve the best detection effect for feature learning and classification detection at the same time, and realize online real-time detection of multiple targets; the invention introduces an information feedback mechanism on the basis of multi-target recognition, and automatically controls Load, adjust the imaging equipment test field, realize high-definition imaging of power components, and effectively improve the imaging quality.

Description

technical field [0001] The invention relates to an autonomous scanning method for transmission poles and towers based on the hovering state of an aircraft, and belongs to the technical field of transmission poles and towers scanning. Background technique [0002] As an important part of electric power construction, transmission lines have increased investment in transmission lines in recent years. Most of the transmission lines under the jurisdiction of the company are located in mountainous areas, with the characteristics of variable climate, complex geological environment, high mountains and dense forests, thick fog and strong wind, and have special requirements for machine patrol. During the dynamic flight process, the relative positional relationship between the pod and the transmission line is also dynamic. Sometimes it is necessary to hover at multiple points and to fly at a higher altitude. It is necessary to manually operate the remote control of the aircraft and the...
