Vehicle Crane Live View Overlays for Safe Maneuvering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle crane operation systems lack effective means to safely and simply maneuver cranes in harsh environments without additional sensor systems, which can malfunction and require maintenance, and fail to provide clear visual cues for movement restrictions.
Innovation Solution
A method that generates a calibrated live bird's-eye view of the crane's surroundings using cameras on the lower carriage, superposing crane-specific movement range overlays onto the live image, allowing the driver to recognize safe positioning and potential collisions without additional sensors, using permanently stored data for fixed-programmed, scale-based identifications of jib supports and superstructure pivoting ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional sensor systems are used to detect movement ranges and obstacles, then measurement precision and safety are improved, but device complexity and maintenance requirements increase
Solution Approach 1:
The patent creates a virtual copy of the physical crane and its movement ranges by generating a bird's-eye view image and superimposing identifications of movement ranges onto it. This virtual representation allows the driver to visualize safe operating areas without requiring additional physical sensors to detect and track movement boundaries in real-time
Solution Approach 2:
The patent replaces potential mechanical sensor systems with a computational imaging approach. By using cameras to capture the environment and software to generate overlaid visualizations of movement ranges, the system substitutes complex mechanical sensing and actuation with optical capture and digital processing
2Measurement precision
If additional sensor systems are deployed to monitor surroundings, then measurement precision is improved, but ease of operation and maintenance burden worsen
Solution Approach 1:
The system creates a virtual model of the crane's movement capabilities by calculating and displaying identifications of movement ranges on a bird's-eye view. This virtual representation provides precise measurement information about safe operating areas without requiring complex sensor arrays that would complicate operation and maintenance
3Ease of operation
If crane-specific calibrated views are generated with permanently stored movement ranges, then ease of operation is improved, but loss of information increases due to fixed-programmed overlays
Solution Approach 1:
The patent performs preliminary calibration by determining and permanently storing the specific movement ranges of each crane's components (jib support extension lengths, superstructure pivoting ranges) before operation. This advance preparation allows the system to display accurate, pre-calculated movement boundaries without requiring real-time complex calculations, improving ease of operation while maintaining information accuracy through crane-specific customization

AI summary
A method for operating a vehicle crane having a lower chassis with boom supports and having an upper chassis with a counterweight in which a live view of the surroundings of the vehicle crane is displayed to the driver. To provide a possibility of operating the vehicle crane that permits safe and simplified manuvering and use, the live view is created at least by way of cameras arranged on the lower chassis, markings indicating the movement ranges of the boom supports and the pivot range of the upper chassis are superimposed to scale on the live view, where the markings are hard-programmed crane-specific overlays and the live view is a crane-specific view that is calibrated with regard to dimensions.
