Solution Approach 1:

The system uses automated identification processes including cameras, GPS, and image processing algorithms to self-correct and update data about terrain conditions, log locations, and vehicle positions without requiring manual data input, thereby maintaining data accuracy while improving productivity

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Manual data input operations are replaced by an automated electronic system that uses image processing, GPS tracking, and computer algorithms to automatically detect and correct changes in terrain conditions, log locations, and logistic information

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Loss of information

If constant tracking of logs and log piles is implemented, then the system can monitor changing locations and conditions, but the device complexity increases

Engineering Contradiction:

Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The system uses multi-functional integrated components where cameras serve both visual recording and object identification purposes, GPS provides both positioning and tracking functions, and the same image processing system handles multiple types of objects (logs, log piles, terrain features) simultaneously, reducing overall system complexity while maintaining comprehensive tracking

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system creates digital copies of physical objects through image processing and data modeling, allowing virtual tracking of logs and log piles without requiring physical tagging or complex identification mechanisms on each object

Inventive Principle:

Solution Approach 1:

The system uses image processing algorithms and computer vision techniques as intermediaries between the camera and object identification, enabling accurate recognition of logs and objects even under varying light and weather conditions by processing and enhancing the visual data before final identification

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system adapts its identification parameters and processing algorithms based on detected environmental conditions, adjusting image processing settings, contrast thresholds, and recognition criteria to maintain measurement precision under different weather and light conditions
