Emotion Estimation Apparatus for Vehicle Design Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for evaluating the aesthetic appearance of vehicles are limited by relying on specific evaluators in controlled settings, failing to capture dynamic evaluations from a large number of unspecified persons, which is essential for understanding customer appetite and design preferences.
Innovation Solution
A data collection apparatus equipped with a processor and storage, utilizing a surrounding environment imaging camera, vehicle state detector, GPS antenna, and communicators to estimate emotions of individuals viewing a vehicle, correlate emotion data with vehicle state data, and store this information for analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a limited number of evaluators are used in controlled settings, then evaluation costs and time are reduced, but the representativeness and accuracy of evaluation results deteriorate
Solution Approach 1:
The patent replaces the mechanical system of manual evaluation by human experts with an automated image processing system that uses computer vision algorithms to detect and analyze vehicle appearances in images, thereby achieving both high efficiency and accurate emotional factor evaluation
Solution Approach 2:
The patent uses images as copies or representations of the actual vehicle appearance scenarios, allowing evaluation of vehicle aesthetic and emotional factors through image data rather than requiring physical presence of evaluators, thus enabling remote and automated evaluation
2Measurement precision
If a large number of sample evaluators are used to obtain representative evaluation results, then evaluation accuracy improves, but costs and time constraints increase
Solution Approach 1:
The system enables self-service evaluation where the vehicle images themselves are automatically analyzed by the image processing system without requiring human evaluators to manually assess each vehicle, allowing the system to process numerous vehicles independently and efficiently
Solution Approach 2:
The image processing system serves multiple functions simultaneously: it detects vehicle appearances, evaluates aesthetic factors, analyzes emotional responses, and processes data from multiple sources, making it a universal evaluation platform that handles diverse evaluation tasks efficiently
3Measurement precision
If objective evaluation criteria are used for functional factors, then evaluation precision improves, but the ability to capture emotional and aesthetic factors deteriorates
Solution Approach 1:
The patent changes the evaluation parameters from traditional functional specifications to image-based visual characteristics, using color, shape, and compositional parameters extracted from images to objectively evaluate aesthetic and emotional factors that were previously只能 be assessed subjectively
Solution Approach 2:
The patent introduces image data as an intermediary between the vehicle and the evaluation system, allowing objective measurement of emotional and aesthetic factors through visual representation, thereby bridging the gap between subjective emotional response and objective measurement
Data Source
AI summary
A data collection apparatus includes a processor and a storage. The processor is configured to: estimate an emotion of a person watching an own vehicle on the basis of an image data of a surrounding environment of the own vehicle; generate emotion data including an estimate of the emotion of the person watching the own vehicle; specify a state of the own vehicle viewed by the person watching the own vehicle; and correlate the emotion data with the specified state of the own vehicle. The storage is configured to be caused by the processor to store the emotion data correlated with the specified state of the own vehicle.
