Solution Overview

Problem

In remote assisting automatic driving, users rely on planar video images to perceive the distance between unmanned devices and obstacles, leading to inadequate environment engagement and perception, potentially resulting in incorrect instructions and safety threats.

Innovation Solution

The method involves capturing and processing scene information from multiple environment angles to generate a Virtual Reality (VR) scene, which is displayed to the user, enabling accurate remote assisting driving operations by providing a more immersive and accurate representation of the environment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If planar video images are used for remote assisting driving, then the system complexity is low, but the user's environment perception accuracy deteriorates

Engineering Contradiction:
Improvesystem complexityVSAvoidenvironment perception accuracy
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent transitions from 2D planar video images to 3D VR (Virtual Reality) scenes, adding a spatial dimension to the visual information. This dimensional change enables users to perceive depth, distance, and spatial relationships more accurately, directly addressing the limitation of planar images in providing environment perception accuracy while maintaining manageable system complexity through standardized VR processing pipelines.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent introduces a VR scene generation module as an intermediary between the unmanned device's camera system and the user's display interface. This intermediary processes raw video feeds from multiple angles, synthesizes them into coherent 3D VR environments, and presents them to users, thereby enhancing perception accuracy without requiring direct complex hardware modifications to the unmanned device itself.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If multiple environment angles are captured and processed into VR scene, then the environment perception accuracy is improved, but the device complexity increases

Engineering Contradiction:
Improveenvironment perception accuracyVSAvoiddevice complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent divides the environment capture task into multiple discrete camera angles (e.g., front, rear, left, right views) captured simultaneously by separate imaging units. Each angle is processed independently into its own video stream, which are then synthesized into a comprehensive VR scene. This segmentation allows the system to achieve accurate multi-angle perception while managing complexity through modular, independent processing channels.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent creates virtual copies of the physical environment from multiple camera perspectives, synthesizing these copies into a unified VR representation. Instead of requiring a single complex omnidirectional camera, the system uses multiple standard cameras whose feeds are digitally replicated and repositioned to construct the VR scene, thereby achieving accurate environment perception using conventional, manageable components.

Inventive Principle:
Principle #26Copying

3Measurement precision

If VR scene is displayed to user, then the remote assisting driving accuracy is improved, but the information processing time increases

Engineering Contradiction:
Improveremote assisting driving accuracyVSAvoidinformation processing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent performs preliminary processing of video feeds from multiple angles simultaneously as they are captured, pre-synchronizing and pre-aligning the streams before VR scene synthesis. This preliminary action ensures that when the VR scene is generated and displayed, the processing is already optimized, minimizing additional latency and reducing the overall information processing time while maintaining high remote assisting driving accuracy.
