the LSD_room.bag has inside the intrinsic parameters (camera_info). you only need to provide this in case of your camera is not publishing this topic. Just do what is described in the README.md section 1. it works fine.
yes! I have do it follow README.md section 1,and it works well .but now I want to connect usb camera(it is an ordinary camera) to run “ live_slam ”.
but I don't Know what does the “yourstreamtopic” mean.So I try to only use cameraCalibration.cfg of dataset slam to run the following order. but Not found the cameraCalibration.cfg.
rosrun lsd_slam_core live_slam /image:=
if there is no cameraCalibration.cfg. how can I run “ live_slam ” with an ordinary usb camera?
you need to read a bit about ROS concepts, to understand about topics. it will be very difficult to use this code without that. You need to use a node to read your camera and publish the image_raw topic http://wiki.ros.org/usb_cam
for calibration and generation of the camera_info file follow this tutorial. http://wiki.ros.org/camera_calibration/Tutorials/MonocularCalibration
good luck
thanks a lot. Enjoy yourself!
where is the cameraCalibration.cfg of dataset slam,please help me
