cameracalibrator.launch run successfully, but shows nothing?

[wkyoun]

I tried to calibrate camera using ethzasl_ptam

My camera is webcam: ODROID USB-CAM 720P, purchasing from following sites

http://www.hardkernel.com/main/products/prdt_info.php?g_code=G137517754892

when I command this, it runs successfully,

However, nothing shows up.

What is the problem?

Is it due to camera model that does not support ethzasl_ptam?

did you map the topic correctly?

Try displaying the camera image with "rosrun image_view image_view image:=[your/image/topic]
