The patent US12038279B2 describes an advanced inspection processing system designed for use in construction and building sites. This system comprises two user terminals, each equipped with circuitry that facilitates a comprehensive registration and inspection process. The first user, identified as the person in charge of the inspection, logs in and is presented with a login interface. The system determines the user's current position on-site and provides inspection assistance views to aid in conducting the inspection. Following the inspection, the system generates an inspection result that includes metrics of importance and urgency, which are used to calculate a delivery level. This delivery level helps identify a delivery destination pattern, allowing the system to determine the appropriate related person to receive and verify the inspection results. The results are recorded in a three-dimensional model of the building structure, ensuring accurate documentation and communication.

The second user terminal, intended for the related person who checks the inspection results, also features a login interface. Upon logging in, the system identifies the second user's position and generates a virtual image of the building structure corresponding to that location. The second user can capture an actual image of the structure and, if the inspection result pertains to them, the system superimposes the inspection result onto the virtual image to create an output image. This output image is then presented to the second user, who can confirm the inspection results based on the visual data provided. The system further includes capabilities to identify visual ranges, related persons based on constructor information, delivery levels, and construction schedules, enhancing the overall efficiency and accuracy of the inspection process.
