🔥 Content Introduction
The simulation and visualization of UAV flight trajectories is an important tool for UAV path planning, task scheduling, and flight safety assessment. By intuitively presenting the complete process of UAV flight from takeoff, waypoint navigation to landing, it helps operators anticipate flight risks, optimize path efficiency, and provides a visual basis for algorithm validation (such as trajectory tracking control algorithms). This article focuses on the simulation and visualization of the entire flight trajectory of UAVs, detailing the trajectory characteristics, modeling methods, and visualization implementation plans for each stage.

📣 Sample Code
% Compute distance of each point from central point in the scene (3D – XYZ space)
d_i = sqrt((x_i-r_x_img/2).^2 + (y_i-r_y_img/2).^2);
% Compute distance of each point from central point in the orthomap (2D – XY plane)
d_om = pElev.*sin(atan(d_i/f));
% Obtain angular distance of each point from central point in the orthomap (2D – XY plane)
theta = atan2(y_i-r_y_img/2,x_i-r_x_img/2);
% Compute the actual position of each point in the orthomap (2D – XY plane)
