Application: Surveying system, surveying method, and program (Patent ID: US20240102801A1)
The patent filed by Topcon Corp describes a surveying system that automates surveying operations by associating surveying conditions, photographic images of surveying targets, and environmental data with each other. This data is used to generate an AI-estimated model for estimating new surveying conditions based on image data and environmental data. The system includes a surveying apparatus, camera, and processor/circuitry for acquiring and storing the necessary data.
The surveying system further includes a GNSS position measurement device for surveying positions based on navigation signals, with environmental data being acquired based on position information obtained from the device. The processor/circuitry is also capable of estimating surveying conditions based on environmental data, with the appropriateness of the estimation determined based on surveying results. Additionally, the patent describes a surveying method and a computer recording medium storing executable instructions for performing surveying, obtaining image data, acquiring environmental data, and storing all relevant data in association with each other.
