Object Classification Recordings for Distance-Based ML Labeling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver assistance systems face challenges in achieving high-quality object type recognition due to inconsistencies in object classification, particularly at varying distances, which affects the reliability and effectiveness of systems like emergency braking assistants and adaptive cruise control.
Innovation Solution
A method and system for providing classified digital recordings using radar, LIDAR, or camera data, where multiple recordings of an object at different distances are analyzed to identify and label relevant segments for supervised learning, with a fast memory for initial recordings and a slower memory for classified recordings, allowing for improved classification quality through user verification and correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple digital recordings are captured and classified at different distances to improve object type recognition quality, then the classification accuracy is improved, but the processing time and system complexity increase
Solution Approach 1:
The system performs preliminary classification of digital recordings at different distances before final object type recognition. By pre-classifying recordings based on distance characteristics and selecting only those with classification differences for further processing, the system reduces the complexity of the main recognition task while maintaining high accuracy.
Solution Approach 2:
The object type recognition process is segmented into multiple stages: initial classification at different distances, comparison of classification results, selection of relevant recordings, and final recognition. This segmentation allows the system to handle complex tasks in manageable steps, improving accuracy without overwhelming system resources.
2Measurement precision
If multiple digital recordings are captured and classified at different distances to improve object type recognition quality, then the classification accuracy is improved, but the processing time increases
Solution Approach 1:
The system extracts only the essential information needed for accurate classification by comparing results from different distances. Instead of processing all recorded data equally, it identifies and processes only those recordings where classification differences occur, significantly reducing processing time while maintaining accuracy improvement.
Solution Approach 2:
The system performs classification at multiple distances (excessive action) but only processes the subset of recordings where classification results differ (partial action). This approach ensures high accuracy by using multiple perspectives while avoiding the time cost of processing all possible recordings.
3Productivity
If classified digital recordings are stored in a memory system with rapid and slower access times, then the data management efficiency is improved, but the memory system complexity increases
Solution Approach 1:
The memory system is segmented into two distinct parts: a rapid access memory for frequently used classification data and a slower memory for archival storage. This segmentation allows the system to optimize access patterns for different data types, improving overall data management efficiency while keeping each memory component relatively simple.
Solution Approach 2:
The system uses an intermediary control mechanism to manage data transfer between rapid and slower memory. This intermediary layer handles the complexity of coordinated access and storage, allowing both memory types to work together efficiently without requiring complex integrated memory architecture.

AI summary
A system and method for providing classified digital recordings, for a system for automatic machine learning. A first digital recording is captured at a first point in time which includes an object situated at the first point in time at a first distance from the recording unit. A first classification of the object is determined using the data of the first digital recording. At a second point in time, a second digital recording is captured, which includes the object situated at the second point in time at a second distance from the recording unit. A second classification of the object is determined using the data of the second digital recording. A digital recording classified using a result of the second classification is provided, which includes at least a part of the first digital recording when a result of the first classification differs from the result of the second classification.
