我在运行程序时遇到错误,错误如下
com.googlecode.javacv.FrameGrabber$Exception: videoInput.getPixels() Error: Could not get pixels.
at com.googlecode.javacv.VideoInputFrameGrabber.grab(VideoInputFrameGrabber.java:168)
at Robot.run(Robot.java:107)
at java.lang.Thread.run(Unknown Source)
***** VIDEOINPUT LIBRARY - 0.1995 - TFW07 *****
SETUP: Setting up device 0
SETUP: HD Pro Webcam C920
SETUP: Couldn't find preview pin using SmartTee
SETUP: Capture callback set
SETUP: Device is setup and ready to capture.
并在以下行中显示错误
rameGrabber抓手= new VideoInputFrameGrabber(0);
// 1个用于下一个摄像头
grabber.start();
IplImage img = null;
while (true) {
long sleepTime= (long)((100000 / 60));
Thread.sleep(sleepTime);
img = grabber.grab();//gettin error on this line..
最佳答案
我对此也有类似的问题。答案在这个论坛中(https://groups.google.com/forum/#!msg/javacv/yD99RSl7oCI/KQIRoOIqcK4J)
尝试使用javaCV.OpenCVFrameGrabber而不是VideoInputFrameGrabber。
更改“FrameGrabber抓取器= new VideoInputFrameGrabber(0);”行。 //下一台相机为1”
到'FrameGrabber抓取器=新的OpenCVFrameGrabber(0); //下一台相机为1”
现在它每次都对我有用。
希望能帮助到你!
