Automated Projection Mapping Previsualization Using Remote 3D Models
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current projection mapping techniques require extensive and costly data collection for complex objects, including high-resolution scanning and geographic site surveys, which are time-consuming and inefficient for previsualization planning, especially when determining projector placement and pose.
Innovation Solution
An automated method and apparatus that utilize a publicly accessible remote mapping server for a three-dimensional computer model of an object, combined with data on Sun and Moon behavior, to generate a time-dependent previsualization projection mapping model, allowing for projector placement and pose determination without the need for high-resolution models initially.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high-resolution scanning services (laser scanner, camera-projector screen-learning system, traditional/manual site survey) are used to obtain a model of the building, then the model accuracy is improved, but the cost and time required are increased
Solution Approach 1:
The patent applies preliminary action by using publicly available pre-existing 3D models from remote mapping servers before conducting any site survey or high-resolution scanning. This allows the projection mapping previsualization to be performed in advance using accessible data, eliminating the need to wait for time-consuming high-resolution model acquisition while still enabling accurate projector placement planning
Solution Approach 2:
The patent uses publicly available 3D models as copies or representations of the target building instead of requiring original high-resolution scans. These copied models from remote mapping servers contain sufficient geometric and geographic information to perform projection mapping previsualization, avoiding the need to create new high-resolution models through expensive and time-consuming scanning processes
2Measurement precision
If high-resolution scanning services are used to obtain a model of the building, then the model accuracy is improved, but the cost is increased
Solution Approach 1:
The patent uses publicly available 3D models as copies or representations of the target building instead of requiring original high-resolution scans. These copied models from remote mapping servers contain sufficient geometric and geographic information to perform projection mapping previsualization, avoiding the need to create new high-resolution models through expensive and time-consuming scanning processes
Solution Approach 2:
The patent employs inexpensive publicly available 3D models from remote mapping servers as disposable or temporary representations for previsualization purposes. These models are sufficient for planning and projector placement determination, eliminating the need for expensive high-resolution scanning services while still achieving the required accuracy for effective projection mapping design
3Measurement precision
If geographic site survey is performed to determine projector placement and pose, then the accuracy of projector placement is improved, but the time and cost are increased
Solution Approach 1:
The patent performs preliminary projector placement determination using publicly available 3D models and geographic data before conducting any site survey. By calculating optimal projector positions and poses in advance using remote mapping server data, the system eliminates the need for time-consuming on-site measurements while maintaining accurate placement planning
Solution Approach 2:
The patent uses geographic and spatial data from remote mapping servers as copies of the actual site conditions to determine projector placement. This approach allows accurate previsualization of projector positions and orientations without requiring physical site surveys, saving time while maintaining placement accuracy through the use of pre-existing geographic reference data
Data Source
AI summary
A method and apparatus for automated projection mapping previsualization is provided. A computer model of an object is received, at a controller of a device, from a publicly accessible remote mapping server, the computer model comprising a publicly available three-dimensional computer model, the computer model defining an object in geographic coordinates and elevation coordinates, the object located at given geographic coordinates. The controller generates a time dependent previsualization projection mapping model for the object using images to be projected onto the object, the computer model, and data for generating one or more of Sun behavior and the Moon behavior at the given geographic coordinates. The controller controls a display device to render a previsualization of the time dependent previsualization projection mapping model.
