“…In equation ( 3), c A and c B represent the center point of the prediction and the target box, and l represents the diagonal distance in the minimum area of the target box and the prediction box, the convergence speed can be optimized if the two do not coincide [23]. The prediction box aspect ratio is taken into account, as shown in equation ( 4).…”

As computer vision and artificial intelligence develop, the research on basketball fixed-point shooting hit prediction based on human pose estimation algorithm becomes a topic of great concern. To construct a basketball fixed-point shooting hit prediction model, a new object detection algorithm was designed, and the You Only Look Once version 5 algorithm was optimized on the basis of GIoU loss function and Convolutional Block Attention Module. Then, a new human pose estimation algorithmwas designed based on the OpenPose algorithm. Results showed that the average accuracy of the improved YOLOv5 algorithm reached 95.34% when the number of iterations was 50. In the comparison among improved OpenPose and other algorithms, improved OpenPose performed better, with a recall rate of 96.23%, an accuracy of 87.16%, a precision of 89.75%, and an F1 value of 88.19%. In the comparison with other models, the area of receiver operating characteristic curve was the largest, reaching 0.974, and the F1 value, accuracy and recall rate of the research model were the highest, reaching 95.54%, 96.39% and 98.25%, respectively. Results show that it effectively predicts the shoot hit of basketball fixed-point shooting, which provides a useful reference for tactical analysis and player performance evaluation in basketball games.Povzetek: Raziskava predstavlja napovedni model za zadetke pri košarkarskem metu s fiksne točke na osnovi algoritma za ocenjevanje človeške drže, kar je koristno za taktično analizo in ocenjevanje igralcev v košarki.
