Weapon Simulator Frame Tagging for Assignment Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing weapon simulators, the association between a light spot on the projection surface and the corresponding simulation input device can be lost, requiring quick restoration, which complicates evaluation and often necessitates high-performance evaluation devices.
Innovation Solution
A method is introduced where each frame captured by the camera is assigned a unique identifier through a tag with variable properties, allowing for delayed evaluation and enabling the use of less expensive evaluation devices, by synchronizing the generation of tags and light points with frame transmission and using an additional projection source to create distinguishable tags for each frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the association between light spots and simulation input devices is maintained through continuous evaluation, then the assignment accuracy is improved, but the evaluation device complexity and cost increase
Solution Approach 1:
The patent applies preliminary action by embedding unique identifiers (tags) into each frame before evaluation occurs. These tags contain information about the temporal and spatial relationship between light spots and simulation input devices, allowing the evaluation device to accurately assign light spots to devices without requiring complex real-time processing or high-performance hardware. The identification information is prepared in advance, simplifying the evaluation task.
Solution Approach 2:
The patent introduces tags as an intermediary element that mediates between the light spots generated by simulation input devices and the evaluation device. These tags carry identification information that bridges the gap between the optical signals and their source devices, enabling accurate assignment without requiring the evaluation device to perform complex real-time tracking or association algorithms.

The patent employs inexpensive tags with embedded identification information as disposable markers in the optical stream. These tags are simple to generate and process, allowing standard, low-cost evaluation devices to achieve accurate light spot assignment without requiring expensive high-performance hardware. The tags are transient optical elements that serve their purpose and are discarded.

Function Achieved in This Case
This method allows for rapid and efficient assignment of light points to simulation input devices, even after a time interval, using standard computing devices, without the need for immediate evaluation, thus simplifying the evaluation process and reducing hardware requirements.
Implementation Method 1
an additional projection source, which is not a simulation input device and which generates a tag with a tag property on the projection surface
Implementation Method 2
the content of the projection surface, including the light points generated by the simulation input devices on the projection surface, is continuously captured by a camera and transmitted using successive frames
Implementation Method 3
These typically have a device (for example a laser source with appropriate optics) which generates a point of light on the projection surface at the location targeted by the simulation input device
