Vehicle Digital Replica via Marker-Based 3D Photogrammetry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle purchasing processes lack transparency, as customers cannot accurately visualize the exact vehicle they are buying, leading to potential 'lemon' sales and surprises upon physical inspection, due to generic photos and lack of interactive, detailed 3D models.
Innovation Solution
A method for creating a complete interactive three-dimensional virtual model of a vehicle using physical markers placed around the vehicle, capturing images from multiple angles, and applying a schema to create an image mesh with a navigation grid, allowing users to navigate and interact with the model through an internet-enabled device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If generic photos are used to display vehicles for sale, then the device complexity is reduced and ease of manufacture is improved, but the information completeness deteriorates and measurement precision worsens
Solution Approach 1:
The vehicle is divided into multiple capture zones defined by physical markers placed at specific locations around the vehicle. Each zone captures specific details, and the complete vehicle model is assembled by combining these segmented views. This segmentation allows comprehensive documentation of vehicle condition without requiring a single complex imaging system.
Solution Approach 2:
A complete digital copy or replica of the vehicle is created through photogrammetry, capturing the actual vehicle's exact condition including imperfections. This digital copy serves as an accurate representation that can be viewed from multiple angles, providing complete information about the vehicle's state without requiring physical inspection.
2Loss of information
If detailed 3D models with multiple perspectives are created, then information completeness is improved and measurement precision is improved, but device complexity increases and ease of operation worsens
Solution Approach 1:
The system transitions from 2D photos to a 3D virtual model that can be navigated from multiple perspectives. The 3D model allows users to view the vehicle from any angle, providing comprehensive information about condition details while maintaining ease of operation through intuitive web-based navigation controls.
Solution Approach 2:
A web-based viewer serves as an intermediary between the complex 3D model data and the end user. This intermediary layer handles the complexity of rendering and navigation, presenting the information in an easily accessible format through standard web browsers without requiring specialized software or technical knowledge.
3Measurement precision
If physical markers are placed around the vehicle and multiple images are captured, then measurement precision is improved and information completeness is improved, but loss of time increases and productivity decreases
Solution Approach 1:
Physical markers are pre-placed at standardized locations around the vehicle before image capture begins. This preliminary setup creates a consistent framework that guides the imaging process, ensuring all necessary views are captured systematically. The pre-defined marker positions eliminate the need for complex real-time positioning calculations during image capture.
Solution Approach 2:
The system uses standardized parameters for marker placement, image resolution, and capture angles that can be adjusted based on vehicle size and type. These parameter changes allow the same basic process to be applied to different vehicles efficiently, reducing setup time while maintaining measurement precision through consistent documentation standards.

AI summary
A three-dimensional complete virtual model of a real-world vehicle and its method of construction is disclosed. The virtual model can be used to provide virtual tours of a vehicle, which can be a land, sea, or air vehicle. The real-world vehicle can be down with both open and closed doors, and will include images of the interior and exterior of the vehicle.
