US12435958 - Real-time shot detection and scoring based on target image processing

An electronic target measurement system is disclosed such that the system includes image capture device(s), an access point device, and a user device. Each image capture device acquires a series of successive real-time images of at least one target with a plurality of regions of interest (ROIs). The access point device receives the images and transmits the images to a user device. The user device performs image preprocessing on the images, determines via an image differentiation process that a difference exists between the images, extracts the ROIs and locations of impact (LOIs) from the received image, and determines ROI center points, LOIs within the ROIs, and LOI center points. The user device also determines regional scores based on the distances between the ROI center points the LOI center points, and then a total score by adding the regional scores for the plurality of extracted ROIs.

The patent describes an electronic target measurement system that utilizes image capture devices to acquire real-time images of a target, allowing for the extraction of regions of interest and locations of impact. The system processes these images to determine scores based on the distance between the center points of the regions and impacts, providing a comprehensive scoring mechanism for shooting accuracy.
