AI Technical Summary

Technical Problem

Traditional photovoltaic power plant design methods based on two-dimensional plan drawings are difficult to meet the needs of modern photovoltaic power plants for precise layout, efficient operation and maintenance, and intelligent monitoring. Especially under complex terrain conditions, they cannot accurately reflect the actual spatial relationships and lighting conditions of the power plant, which affects power generation efficiency and operation and maintenance costs.

Method used

Using panoramic image acquisition and 3D modeling technology, panoramic images are acquired by installing fixed acquisition equipment in a multi-point matrix, a 3D virtual model is constructed, and the pre-processed panoramic images are mapped onto the 3D virtual model to form a 3D virtual fusion model.

Benefits of technology

It improves modeling accuracy and efficiency, ensures that the model is highly consistent with the actual situation, enhances the work efficiency of design and operation and maintenance personnel, provides the possibility of remote monitoring and intelligent management, and improves the operation efficiency and safety of photovoltaic power plants.

Abstract

This invention proposes a method and system for 3D modeling of photovoltaic power plants, including acquiring panoramic images of the construction area of ​​the photovoltaic power plant; constructing a 3D virtual model based on the acquired modeling data of the photovoltaic power plant; and mapping a preprocessed panoramic image obtained after preprocessing the panoramic image onto the 3D virtual model to obtain a 3D virtual fusion model. This method uses a multi-point matrix to install fixed acquisition devices and assigns them numbers, combined with mobile devices to assist in image acquisition, enabling comprehensive and detailed capture of panoramic information of the photovoltaic power plant construction area. Simultaneously, it intelligently stitches the second image acquired by the mobile device with the first image from the fixed acquisition device and associates it with the fixed acquisition device numbers for complex or special areas, ensuring the integrity and accuracy of the image information, providing a high-quality data foundation for subsequent modeling, and improving the accuracy and efficiency of 3D modeling of photovoltaic power plants.
