BUILDING CHANGE DETECTION DEVICE, BUILDING CHANGE DETECTION SYSTEM, AND BUILDING CHANGE DETECTION METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18273474 titled 'BUILDING CHANGE DETECTION DEVICE, BUILDING CHANGE DETECTION SYSTEM, AND BUILDING CHANGE DETECTION METHOD
Simplified Explanation
The purpose of this invention is to provide a building change detection device that can easily compare a three-dimensional model of a building at different points in time with a model based on reference information.
- Measurement data acquisition means: Acquires measurement data based on emitted and reflected laser light onto a region under measurement, including a building.
- Building model generation means: Uses the measurement data to generate a three-dimensional point-cloud model of the building.
- Building reference model acquisition means: Acquires a building reference model.
- Display control means: Controls the display of images including the building reference model and the building model.
Potential Applications
This technology can be used in construction projects to track changes in buildings over time, in urban planning to monitor development, and in disaster response to assess damage to buildings.
Problems Solved
This technology solves the problem of accurately comparing building models at different points in time, making it easier to detect changes and assess the impact of those changes.
Benefits
The benefits of this technology include improved accuracy in detecting building changes, increased efficiency in monitoring building developments, and enhanced disaster response capabilities.
Potential Commercial Applications
Potential commercial applications of this technology include offering building change detection services to construction companies, urban planning agencies, and disaster response organizations.
Possible Prior Art
One possible prior art for this technology could be LiDAR technology used for building modeling and monitoring, but the specific focus on building change detection may be a novel aspect of this invention.
Unanswered Questions
How does this technology handle changes in building materials over time?
The article does not specify how the building change detection device accounts for changes in building materials that may occur over time. This could be an important factor in accurately detecting and analyzing building changes.
What is the potential impact of weather conditions on the accuracy of the measurement data acquisition?
The article does not address how weather conditions, such as rain or fog, may affect the accuracy of the measurement data acquisition process. Understanding the limitations of the device in different weather conditions could be crucial for its practical application.
Original Abstract Submitted
The purpose of this invention is to provide a building change detection device, and the like, that make it possible to easily compare a three-dimensional model of a building corresponding to individual points in time and a model of the building based on reference information. A building change detection device comprises a measurement data acquisition means for acquiring measurement data indicating the results of measurement based on emitted laser light emitted onto a region under measurement including a building and reflected laser light, a building model generation means for using the measurement data to generate a building model that is a three-dimensional point-cloud model of the building, a building reference model acquisition means for acquiring a building reference model, and a display control means for carrying out control for displaying a first image including the building reference model and the building model.
