Disertasi ini adalah berkaitan analisis trajektori bola berdasarkan pemprosesan imej dan simulasi. Data yang digunakan dalam disertasi adalah dua video untuk menentukan parameter permulaan yang boleh menjejaskan trajektori bola tenis meja dan bola sepak. Objektif disertasi ini adalah untuk memplotkan dan menganalisa trajektori bola. Teknik pemprosesan imej digunakan untuk menangkap unjuran. Motivasi penyelidikan ini adalah untuk menentukan kewujudan putaran dalam trajektori dengan parameter awal tidak diketahui. Video pertama adalah video berkelajuan tinggi yang dirakam pada 1000 bingkai sesaat. Video berkelajuan tinggi merakam unjuran awal bola tenis meja. Putaran tidak diketahui, oleh itu melalui simulasi Matlab kewujudan putaran ditentukan. Parameter awal dari video dikira bagi tujuan replikasi unjuran secara matematik. Video kedua adalah video penyiaran langsung yang dirakam pada kira-kira 30 bingkai sesaat. Video ini dianalisis dalam pandangan tiga dimensi untuk menentukan kewujudan putaran. Jenis putaran sama ada bola sepak mengalami putaran atas, putaran belakang atau putaran tepi juga dianalisis. Penemuan disertasi ini membuktikan kewujudan putaran atas apabila bola tenis meja dilancarkan. Bola sepak dalam video ini mempunyai putaran belakang ketika bergerak ke arah y-z. Trajektori bola sepak dan bola tenis meja berjaya diplotkan. This dissertation is about trajectory analysis of ball based on image processing and simulation. Data used in this dissertation are two videos to determine the initial parameters that can affect the trajectory of the table tennis ball and football. Objective of this dissertation is to plot and analyse the trajectory of balls. Image processing techniques were used to capture the projection. The motivation of this research is to determine the existence of spin in a trajectory where the initial parameters are unknown. The first video was a high speed video captured at 1000 frame per second. The high speed video captured the initial projection of a table tennis ball. The spin is unknown; therefore through Matlab simulations the existence of spin is determined. Initial parameters from the video are computed in order to replicate the projectile mathematically. The second video is a broadcasting video that captured at approximately 30 frames per second. This video was analysed in a three dimensional view to determine the existence of spin. The type of spin whether the football was experiencing topspin, backspin or sidespin was also analysed. The findings of this dissertation shows the existence of topspin when the table tennis ball was launched. The football in the video had a backspin while moving in the y-z direction. The projectile of the football and table tennis ball is successfully plotted.
