Construction Machine Camera System Seam Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Construction machines face poor visibility of peripheral areas due to patchy camera visualization, leading to potential hazards, and existing solutions with multiple cameras increase seam-induced vision errors.
Innovation Solution
A construction machine with at least three strategically mounted camera regions, each with a wide-angle lens and inclined photographing direction, providing overlapping image fields that minimize seams and enhance visual perception of the surrounding space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple monitoring cameras are mounted to cover blind spots, then the monitoring region is improved, but the number of seams between image fields increases causing vision errors
Solution Approach 1:
The patent applies local quality by optimizing specific parameters of the camera system at different mounting locations. Each camera is positioned and angled to capture specific regions with minimal overlap, creating a composite image where each local area is optimized for its specific viewing requirements while reducing seam visibility.
Solution Approach 2:
The patent transitions from a two-dimensional display problem to a three-dimensional spatial arrangement solution. By carefully positioning cameras in three-dimensional space at different heights, angles, and locations on the construction machine, the system optimizes image field coverage and minimizes seams through spatial geometry rather than post-processing.
2Reliability
If cameras are mounted to monitor peripheral areas, then safety is improved, but the complexity of the visualization system increases
Solution Approach 1:
The monitor serves multiple functions by displaying both the composite camera image and the original individual camera images. This allows the system to provide comprehensive safety monitoring while maintaining operational simplicity, as the same display device handles both the optimized composite view and the source images when needed.
Solution Approach 2:
The patent merges multiple camera images into a single composite image that provides a unified view of the area around the construction machine. This combining approach simplifies the visualization system by presenting integrated information rather than requiring the operator to switch between multiple separate camera feeds.
3Loss of information
If camera regions are positioned to eliminate blind spots, then coverage is improved, but seam-induced vision errors increase
Solution Approach 1:
The patent applies parameter changes by systematically adjusting camera mounting parameters including position, angle, and orientation to optimize the balance between coverage and seam visibility. The photographing direction and mounting location are carefully selected to minimize the visual impact of seams while maintaining complete coverage of blind spots.
