2012-02-14 06:33:12 -0500 | commented answer | Proper Sequence for Getting Disparity Map from GPU We looked into adapting the code from stereo_image_proc_gpu however it proved to be more work than expected and we ended up writing our own code. We'd like to eventually release this code to the ROS community however it needs to go through some major revisions before that happens. When the code gets polished and commented a little more what's the best way to get community feedback? |
2012-02-14 06:20:27 -0500 | answered a question | Proper Sequence for Getting Disparity Map from GPU It turned out to be a combination of having the images swapped and the images not being in gray scale (MONO8). |

2012-02-02 05:22:09 -0500 | asked a question | Proper Sequence for Getting Disparity Map from GPU Hello, I'm trying to write a GPU implementation of stereo_image_proc and am having some trouble getting a proper disparity map from my GPU. What I'm wondering is if I missed a filtering step. The current program flow goes as follows.
I know everything up to and including rectifying the cameras images is correct because the rectified images are the same as those returned by stereo_image_proc. Below are the left and right camera images along with the disparity that is returned from the GPU. I also can't explain why there's a black bar on the left of the disparity map. I can provide code if needed but I didn't want to clutter up the post if it was as simple as a missing step. Thanks for any help with this matter! |

[camera] device open failed: [Camera1394::open]: Could not find camera with guid While looking at this problem again, I counted the number of GUID bytes. There should be eight, but there are only seven. Perhaps your camera GUIDs have a leading zero byte. Try opening them like this: I think that will work. If so, we should fix the driver to print GUIDs with the appropriate number of leading zeros. |

[camera] device open failed: [Camera1394::open]: Could not find camera with guid I have 2 cameras connected via firewire, and can open either one independently, when I dont specify the guid. However, when the guid is specified with the command: it gives the following output: I need the images from both cameras for stereo vision. |
