Virtual Property Report Generation from Oblique Aerial Imagery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional ortho-rectified aerial imagery in the remote sensing industry has limited utility as it primarily reveals rooftop views, making it difficult to distinguish between different objects or features, and fails to provide important aspects of structures such as dimensions and details of buildings.
Innovation Solution
A computer system capable of processing aerial imagery to generate virtual property reports, which include detailed measurements and features of structures by analyzing oblique images, such as facets facing streets, entrances, vehicle access, and neighboring parcels, using processor-executable code to transform pixel coordinates into real-world geographic coordinates and store measurements in a database.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If ortho-rectified aerial imagery is used, then the images can be mathematically projected and combined into seamless mosaics, but the imagery only reveals rooftops and does not show sides or important aspects of buildings
Solution Approach 1:
The patent transitions from traditional 2D ortho-rectified aerial imagery to 3D oblique imagery captured at multiple angles. This dimensional change allows the system to capture building facades, sides, and architectural details that are invisible in top-down views, thereby recovering lost building information while maintaining measurement precision through multi-view geometry
2Loss of information
If oblique images are used, then sides and important aspects of structures are revealed, but the images cannot be easily combined into seamless mosaics like ortho-images
Solution Approach 1:
The patent introduces a database as an intermediary component that stores pre-processed building information, measurements, and oblique images. This database mediates between the complex image processing requirements and user information needs, allowing seamless retrieval and presentation of building details without requiring real-time complex processing for each query
3Ease of manufacture
If traditional ortho-rectified imagery is used, then processing is straightforward for mathematical projection, but it is difficult to distinguish between different properties and identify building features
Solution Approach 1:
The patent merges multiple types of data including oblique images, ortho-images, street view images, and structured building information into a unified database system. This combination allows the system to maintain the processing simplicity of ortho-images while enriching property identification capabilities through additional visual and structural data from multiple sources

AI summary
A computer system comprises a processor capable of executing processor executable code operably coupled with a non-transitory computer medium storing processor executable code, which when executed by the processor causes the processor to: (a) receive a first signal over a computer network, the first signal indicative of a request for information about a target structure from a user; (b) in response to receiving the first signal, access a database including information about the target structure; and (c) transmit a second signal over the computer network indicative of a virtual property report for the target structure including at least one image of the target structure. The virtual property report may include information about a facet of the target structure facing a street, location of a main entrance of the target structure, location of a secondary entrance of the target structure, location of vehicle access to the target structure.
