How to get image without storing into disk from gazebo ?

edit

I used to try similar way, but the world file post an error that :undefined symbol: _ZTIN6gazebo12CameraPluginE

Oh, I have solved the above problem by changing the CMake file, but I get the image data with the function ImageData(), and I try many ways to decode this data, but I can not make it. Could you tell me what the data means? How to decode it into a image?

What's the value returned by ImageFormat()?

The value is R8G8B8

I believe that one is 3 bytes per pixel: first byte is red component, second byte is green component, 3rd byte is blue component. It's in row-major order: first pixel is the top left corner of the image, last pixel is the bottom right corner.

After I get the image data, how can I transfer it into the origin image? Maybe with C or Python? I try to use PIL lib to implement this, but I get a wrong image even if I know its format. Could you suggest a way to deal with this requirement?

What is "the origin image"?

I take a picture using camera sensor, and I want to load it in another program, and I can not read the image from disk because it is too slow. So the origin image is the image captured by camera sensor.

Oh, I have known how to recover the origin image by the raw image data, the only problem left is that how can I send this raw data out? By now, I can only get the data when the plugin invokes its function on each update time, what I can do is output it into console or files, but I want to directly send it to another program like C or Python. Could you tell me whether there is a way to implement this?

hi, I have the same problem with you, I want to read the images from a camera in the gazebo, and input the images to the program of image processing. I try to follow the above tips to change the code of CameraDump::OnNewFrame(), but I it is not working. So, can you show me how you did it? my email is lanmessi@hotmail.com
