I fixed the problem of your session_bug_reproduce.zip example in this [commit](https://github.com/introlab/find-object/commit/c6cf667645e6e0ad88c8bdff1b27be9f33bb6eb7). The feature detector was not updated, thus the features in the scene were not the same type than those...

Do you have OpenCV 3 ? Find-Object is building against it but OpenCV 3 is not built with xfeatures2d module (see [opencv_contrib](https://github.com/itseez/opencv_contrib) to install this module). However, Find-Object should still...

find_object uses ROS convention, see [REP 103](http://www.ros.org/reps/rep-0103.html#coordinate-frame-conventions): > > In relation to a body the standard is: > > x forward > y left > z up Also: > In...

See [cv::findHomography()](https://docs.opencv.org/2.4/modules/calib3d/doc/camera_calibration_and_3d_reconstruction.html?highlight=findhomography#findhomography). See also this [example](http://introlab.github.io/find-object/#code-example) (see [here](https://github.com/introlab/find-object/blob/147a8a0dacc032e8a7c22f1a519564766af35613/example/main.cpp#L291-L294) to draw rectangles with Qt) based on this [example](https://docs.opencv.org/2.4/doc/tutorials/features2d/feature_homography/feature_homography.html).

Are you comparing Find-Object built with the same version of OpenCV you are using? There could be some differences on how RANSAC is done. In our code, the rectangle is...

> Shoudl I uninstall libopencv-dev and rebuild cv_bridge and all its dependencies using opencv 3.4? Yes, having only one version of opencv will solve a lot of problems.

Looks like there is no topic /image_raw published. Do you started a camera node? See example [here](https://github.com/introlab/find-object#run): ```bash $ roscore & # Launch your preferred usb camera driver $ rosrun...

For kinect 360, I usually use [freenect_launch](http://wiki.ros.org/freenect_launch): ```bash $ sudo apt-get install ros-kinetic-freenect-launch $ roslaunch freenect_launch freenect.launch depth_registration:=true ```

If you can see the depth and RGB stream with freenect-glview, close it then retry the launch file. This could be a USB problem, is it plugged alone on the...

Is depth_image_proc package installed? The freenect-glview seems to show depth image on left. Beware that kinect cannot see depth below ~40cm, it is why the fingers are black (no depth)....
