如何使用 Aerospace Toolbox 为火箭创建动画

Question

如何在 MATLAB Aerospace Toolbox 中使用 xyz、滚动、俯仰、偏航和时间为火箭创建动画？

这是一些示例数据：

x = 1.0e+06 .*[3.0138, 3.1345, 3.7675, 4.7347,6.1352];
y = 1.0e+07 .*[-1.8160,-1.8244,-1.8326,-1.8232,-1.7877];
z = 1.0e+07 .*[0.9917,0.9980,1.0119,1.0218,1.0261];
r =[ 0,0,0.0046,0.0046,0.0046];
p =[ 89.9900,26.6402,22.4665,16.0608,3.6879];
y =[86.7370,86.7370,86.7810,86.7810,86.7810];
t =[0,95,186,282,380];

这是我目前尝试过的方法：

data = [x',y',z',r',p',y',t'];
h=Aero.Animation;
f=figure;
h.Figure=f;
h.initialize();
h.FramesPerSecond=10
h.TimeScaling = 5;
idx1=h.createBody('delta2.ac','ac');
h.show()
h.bodies{1}.TimeseriesSourceType='Array6DoF';
h.bodies{1}.timeseriesSource=data;
h.Camera.offset=[-150 -150 0];
h.show()
h.VideoRecord = 'on';
h.VideoQuality = 50;
h.VideoCompression = 'Motion JPEG AVI'
h.VideoFilename = 'rocket trajectory';
h.play()
h.VideoRecord='off';

然而，当我尝试运行数据时，火箭不会旋转或平移。

Answer 1

使用以下代码创建了一个工作动画：

6dof 数据应采用以下格式作为数组：[ time, lat, lon, alt, phi , theta, psi]

确保 phi、theta、psi 的单位是弧度而不是度数。

%sixdof_data = [time,lat,long,alt,phi,theta,psi]; % This is if you have data saved as variables
h = Aero.Animation;
h.FramesPerSecond = 20;
h.TimeScaling = 10;
h.createBody('delta2.ac');
h.bodies{1}.TimeseriesSourceType='Array6DoF';
h.Bodies{1}.TimeSeriesSource = sixdof_data;
h.Camera.PositionFcn = @staticCameraPosition;
h.Camera.ViewAngle = 6;
h.show();
h.VideoRecord = 'on';
h.VideoQuality = 50;
h.VideoCompression = 'Motion JPEG AVI';
h.VideoFilename = 'rocket trajectory'
h.play();

下面是一些应该有效的示例数据：
