Path Side Imagery Generation via 3D Optical Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional street view systems using image bubbles cannot provide a realistic view along an entire city block or longer section of the street, requiring users to switch between image bubbles and wait for loading, which is inefficient for viewing scenes along the side of the street.
Innovation Solution
A method and system for generating path side imagery by receiving optical data in three-dimensional geographic coordinates, projecting it onto predefined two-dimensional planes, and calculating pixel values from image data to create street side imagery, allowing seamless viewing of street sides without the need for frequent switching between image bubbles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional image bubble switching is used to view street scenes, then users can view different perspectives, but users must frequently switch between image bubbles and wait for loading, which is inefficient
Solution Approach 1:
The patent combines multiple image bubbles into a single continuous path side imagery by projecting optical data onto a two-dimensional plane. This merging eliminates the need to switch between separate image bubbles, providing a seamless view of the entire street section in one continuous image, thereby improving viewing efficiency and eliminating loading waits between bubbles.
Solution Approach 2:
The patent transforms three-dimensional optical data into a two-dimensional projected representation that displays the entire path side view simultaneously. This dimensionality change allows all street scene information to be presented in a single flat image rather than requiring navigation through multiple three-dimensional image bubbles, resolving the contradiction between viewing completeness and loading efficiency.
2Adaptability or versatility
If image bubbles are used to provide panoramic views, then 360-degree coverage is achieved, but realistic viewing along an entire city block cannot be provided
Solution Approach 1:
The patent merges multiple panoramic image bubbles into a single integrated path side imagery by projecting optical data onto a two-dimensional plane. This combination preserves the comprehensive coverage of individual bubbles while creating a unified realistic view of the entire street section, allowing users to see the complete street scene in one continuous perspective without switching between bubbles.
Solution Approach 2:
The patent projects three-dimensional optical data onto a two-dimensional plane to create a flattened path side view that displays the entire street section simultaneously. This dimensional transformation enables realistic viewing along the entire city block by presenting all street scene elements in a single two-dimensional representation, achieving both comprehensive coverage and realistic street view capability.

AI summary
One or more systems, devices, and/or methods for generating path side imagery are disclosed. For example, a method includes receiving optical data measured in three-dimensional geographic coordinates and image data from at least one image bubble. The optical data is projected onto at least one predefined two-dimensional plane. A pixel value for a point of the optical data on the two-dimensional plane is calculated according to the image data. The pixel value may correspond to color or another graphical attribute. The two-dimensional plane is stored or displayed as street side imagery or other path side imagery. An image file including the pixel value for each point of the optical data may be stored in memory or a map database.
