Solution Overview

Problem

There is a need for further automation in determining whether a vehicle or apparatus is ready to move, considering the motion of objects in its environment to prevent accidents and reduce human oversight.

Innovation Solution

A computer-implemented method and system that analyzes a sequence of images to extract motion information of objects, using object detection and semantic segmentation, and applies a logic-based algorithm to determine if the apparatus is ready to move, integrating a classification model to assess the safety of these movements.

1Extent of automation

If automation is increased to reduce human oversight in determining whether a vehicle is ready to move, then productivity and safety are improved, but device complexity increases

Engineering Contradiction:
Improveautomation of readiness determinationVSAvoidsystem complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The system segments the readiness determination process into distinct functional modules: image acquisition module captures visual data, processing module extracts motion information and applies classification models, and output module generates readiness determination. This modular segmentation enables high automation while managing complexity through organized, independent components that can be developed and maintained separately.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The processing module acts as an intermediary between the image acquisition module and the readiness determination output. It receives raw image data, processes it through multiple classification models (object detection, motion detection, semantic segmentation), and transforms it into structured motion information. This intermediary layer handles the computational complexity internally while presenting a simplified interface for the overall automation system.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If motion information extraction is performed on a sequence of images to accurately determine readiness to move, then reliability is improved, but loss of time increases due to processing requirements

Engineering Contradiction:
Improvereadiness determination accuracyVSAvoidprocessing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary processing by pre-training multiple specialized classification models (object detection model, motion detection model, semantic segmentation model) before runtime. During actual operation, these pre-trained models enable rapid inference on incoming image sequences, reducing real-time processing time while maintaining high reliability through the use of robust, pre-validated detection algorithms.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system processes image sequences at optimized frame rates and sampling intervals rather than continuously analyzing every possible frame. By selecting key frames periodically from the sequence and using temporal interpolation where appropriate, the system achieves reliable motion detection while minimizing total processing time required for readiness determination.

Inventive Principle:
Principle #19Periodic action
