Engineering Contradiction Analysis
1Object-affected harmful factors
If laser beams are used for target practice simulation, then the practice can be performed at any place without live ammunition danger, but the laser beams scatter in the target area making it difficult to find accurate position
Solution Approach 1:
The patent introduces an analysis device as an intermediary between the camera and the target practice system. This device processes the scattered laser beam images through coordinate calculation, laser area identification, and correction algorithms to determine accurate spotted positions, thereby resolving the measurement precision issue while maintaining the safety benefit of laser simulation
Solution Approach 2:
The patent replaces direct mechanical/optical measurement of laser positions with an image processing and computational analysis system. By substituting the direct observation method with automated image analysis algorithms, the system achieves accurate position detection despite laser scattering
2Extent of automation
If image analysis is used to find laser position, then the system can process the scattered laser beams, but it is not easy to find accurate position due to scattering
Solution Approach 1:
The patent applies preliminary correction actions by pre-calculating correction values based on laser area sizes. The analysis device identifies the laser area in the image, determines its size, and applies the appropriate correction value before final position calculation, thereby improving measurement precision through preparatory correction steps
Solution Approach 2:
The patent changes the parameter of coordinate accuracy by introducing correction values that are applied based on laser area size. The system dynamically adjusts the coordinate calculation by adding correction values retrieved from storage, transforming the raw coordinate data into corrected accurate positions

AI summary
A laser shooting training system includes a target device including a target area and a camera for photographing the target area, and an analysis device for calculating a coordinate of a laser discharged to the target area based on an image photographed by the camera, and displaying a spotted position corresponding to the laser coordinate to a user display screen. The analysis device calculates a center coordinate of a laser area included in the image, corrects the center coordinate based on a correction value relating to a size of the laser area, and calculates the laser coordinate.
