Central Multi-Camera Housing Layout for Unmanned Work Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional unmanned operation vehicles with cameras have limited field of view, resulting in blind spots and insufficient peripheral imaging, which hinders obstacle detection and area monitoring efficiency.
Innovation Solution
Arranging multiple cameras at the center of the upper housing surface with overlapping imaging ranges and a rectangular outer periphery, reducing blind spots without altering camera angles or positions, and integrating cameras into a single unit for easier mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the camera is arranged at the edge portion of the housing to capture images of the operation area, then the operation area monitoring is improved, but the peripheral obstacle detection capability deteriorates due to limited field of view and blind spots
Solution Approach 1:
The housing is divided into multiple surface regions (front surface, rear surface, left side surface, right side surface), and cameras are strategically arranged on different surfaces to segment the monitoring tasks. Each camera captures images of specific regions, collectively providing comprehensive coverage without blind spots
Solution Approach 2:
Cameras are arranged in three-dimensional space on different surfaces of the housing rather than all on a single plane. This spatial distribution across multiple dimensions allows each camera to capture images of different regions, eliminating blind spots while maintaining comprehensive monitoring capability
2Loss of information
If multiple cameras are arranged at different positions on the housing to eliminate blind spots, then the peripheral imaging coverage is improved, but the device complexity and mounting difficulty increase
Solution Approach 1:
Each camera is positioned at a specific location on the housing surface optimized for capturing images of particular regions. The arrangement ensures that cameras on different surfaces (front, rear, left, right) have distinct imaging responsibilities, creating complementary fields of view that collectively cover all directions without requiring complex coordination
Solution Approach 2:
The housing surfaces serve multiple functions: they provide structural support for the unmanned operation vehicle and simultaneously serve as mounting locations for cameras. The front surface mounts the first camera for front region imaging, the rear surface mounts the second camera for rear region imaging, and side surfaces mount additional cameras, making the housing structure multi-functional
