dnn_detect

This package provides object detection using OpenCV's Deep Neural Network module.

Documentation is at http://wiki.ros.org/dnn_detect.

The model used by default is from chuanqi305's MobileNet-SSD.

dnn_detect's Issues

Crash dnn_detect Melodic

I'm using ROS melodic, ubuntu 18.04.
I change the right camera and image topic name in dnn_detect.launch

Then, when I run the detector as following it crashes :

roslaunch dnn_detect dnn_detect.launch
and I got this error :

NODES
  /
    dnn_detect (dnn_detect/dnn_detect)

Phantom objects

Objects detected in the previous frame are published and annotated in the current image if no new objects are detected.

Noetic release dnn_detect

error: cv_bridge exception: Image is wrongly formed: step < width * byte_depth * num_channels or 640 != 640 * 2 * 1

when the node dnn_detect subscribes topic /camera/depth/image_rect_raw/comressed , error: error: cv_bridge exception: Image is wrongly formed: step < width * byte_depth * num_channels or 640 != 640 * 2 * 1.
all of the topics of the node realsense_camera:

I want to subscribe the depth topic to get the depth info.
thank you!

Noetic support

Hi there, just wondering if a release for noetic is likely/possible?

I was able to get a successful build for noetic with the changes in #7, I'm not sure what else is required in order to get this released.

Hello developers,

have you ever seen this ?

Any idea ?
