How can I get raw sd size color images?

Open tokyokuma opened this issue 6 years ago • 9 comments

I'm using KinectV2 on Jetson TX2. Considering the processing speed of Jetson, I want to get SD size color image. However, when I subscribed this topic (/kinect2/sd/image_color_rect), the acquired image is a color image combined with the depth image.

I believe that SD color images can be obtained if I can modify this file (kinect2_bridge.cpp). However, I tried several times on my own, but I could not do it well.

help me!!

Sorry, I gave up before solving the problem.

Did you use any alternate for this? I am using both the qhd image topics i.e. kinect2/qhd/image_color and kinect2/qhd/image_depth_rect. I am getting the desired results.

I process images acquired from Kinect using deep learning. I use qhd size, but I resize both RGB and depth image before doing image processing and make it small. At first, this method prevents processing speed reduction.

This need is highly required, help me please!!!!

when I use the qhd size in ROS, the timestamp of received msgs between kinect2/qhd/image_depth_rect and kinect2/qhd/image_color differ 300ms!! Do you konw why? Do you meet this problem?

I think it is because rectification needs some time to be processed.

I am also meeting this problem. I search the kinect2_bridge.cpp file carefully and I find out that the author never publish true SD color image. What a shame!
