在 MATLAB Online 中打开

In order to do this, first create the file loggerFcn.m with the following contents:

function loggerFcn(vidObj, eventData, logger) 
writeVideo(logger, getdata(vidObj, 1));

Then use the following code to create and configure the objects:

% Create videoinput object with appropriate paramaters. 
vid = videoinput(...);   
vid.FramesPerTrigger = 10000;  
% Create a VideoWriter object. 
logger = VideoWriter('myfile.avi', 'Uncompressed AVI'); 
open(logger); 
vid.FramesAcquiredFcn = {@loggerFcn, logger}; 
vid.FramesAcquiredFcnCount = 1; 
start(vid);
