Laser Ranging Source Code with Spot Size Analysis

This method begins with grayscale conversion of the input image before proceeding to calculate the laser spot size. The core algorithm employs a three-point circle fitting approach where multiple iterations of the method reconstruct the circular contour. Through computational geometry, the system ultimately determines the circle's diameter and center coordinates with high accuracy. For enhanced flexibility, the implementation can be extended to accommodate alternative shape-fitting methodologies. Optional approaches include rectangular bounding box analysis or elliptical fitting algorithms to approximate spot morphology. Further research directions involve optimizing computational efficiency through algorithm refinement and accuracy improvements via advanced numerical methods. From an application perspective, this technique can be integrated with complementary image processing workflows such as noise reduction filters, edge detection algorithms, and morphological operations. This integration enables broader functionality including real-time monitoring, precision measurement systems, and automated industrial applications. The modular code structure permits straightforward implementation of additional features like multi-spot analysis and dynamic thresholding adjustments.
