no detect result

[wtq20230227]

I use the camera when D455. After I run the dynamic obstacle detection program, there are all topics that should be subscribed to and published displays in rqt_raph, but the running results are not displayed, and there is a problem with the display of the terminal running dynamic obstacle detection, how can I solve this problem?

Are you able to run with the provided rosbag?

yes，I can run the provided rosbag, How can I solve this problem?

I would suggest to check your topic data by comparing with the rosbag. It seems that you don't have a local position?

I solved the problem that the odometer had no information. He can run. But always after running for a while, the picture in rviz gets stuck, and the terminal shows that detector_node-1 process has died

I have solved the problem that "the process has died". The reason is that the size of depth image produced by D455 is different from the size produced by D435i.
But now ,I meet a new problem. The image ,depth image, U-depth image and bird-eye view are shown in rviz, but there is no box plot containing the point cloud. I don’t know the reason. Can you tell me what information I should provide and where to investigate next?

The pointcloud shows the dynamic objects. Those results shown on the screen are called candidates which means they are not necessarily dynamic.

In my test scenario, there is a moving person who walks at a speed greater than the threshold of 0.15 in the parameter list, but there are still no boxes and point clouds in the rviz. My testing environment is outdoors, will this have an impact? If there is no impact, where might the problem be? Can you help me analsy the reason?

Can you elaborate on how you solved the problem, I'm facing a similar issue; when I try to publish the pose data, the function depthPoseCB gets executed once and then I get the cv::Exception error (Assertion failed !ssize.empty() in function 'resize'). I'm unable to locate this function call for resize but I believe the error is similar to what you faced, as even I'm working with D455 depth images.
