I made the following code changes for the lsd_viewer to display the point cloud .It also solved the Qt issue I was facing. The issue was found to be in the ImageDisplay_OpenCV.cpp file , including the details of the code change I made.
File : lsd_slam/lsd_slam_core/src/IOWrapper/OpenCV/ImageDisplay_OpenCV.cpp
Made changes on line 119 and 125
Changed : return cv::waitKey(milliseconds); to return 1;
A catkin_make later your good to go

Hello, I haven't played around with the Viewer yet. I have been using it primarily to track the pose.

@Young532042725 Have you tried viewing the topic /lsd_slam/pose ?
from lsd_slam.
@kevin-george hello,How to viewing the topic /lsd_slam/pose ? (rostopic list?) What does this mean(Run a cv_camera node. You will need to clone and build the cv_camera ROS package to use this/rosrun cv_camera cv_camera_node /cv_camera/image_raw:=/camera/image_raw)? Does it can use camera on my PC? Dear, Friend, please give me a hand! what is your E-mail?
from lsd_slam.
You would use the command rostopic echo /lsd_slam/pose
Please go through a ROS tutorial before you proceed. It will be difficult for you to navigate the SLAM landscape if you want to use ROS packages without any familiarity :)
