matlab在採集點圖像時崩潰

我有一個pointgrey USB3攝像頭，我用Matlab R2015a接口。一切工作正常，除了我得到隨機的Matlab崩潰 - 通常每10000圖像。下面是崩潰消息。典型的程序我跑的樣子說：matlab在採集點圖像時崩潰

vidobj = imaq.VideoDevice('pointgrey'); 
set(vidobj,'ROI',ROI); 
for i=1:Nimages 
    frame=step(vidobj) 
    here some basic image analysis 
    end

我想不出什麼觸發崩潰。如果有人有任何線索，我會很感激。謝謝，GD

我有這個完全相同的問題。你有沒有發現它？ – hepcat72

是的，我做到了，通過使用：

obj = videoinput(...) 
frame=getsnapshot(obj)

我還是不明白，這兩種方法之間的差異，但是這一個更穩定。希望它有幫助。
