zdepth_image_transport

ROS zdepth image transport plugin

zdepth_image_transport is for faster and lighter depth compression.

Zdepth is a depth compression method with zstd library.

Supported format

Currently supported formats are as below:

  • [x] 16UC1
  • [x] 32FC1

How to try

roslaunch openni2 openni2.launch
rosrun image_transport republish zdepth in:=/camera/depth/image_raw raw out:=/camera/depth_decompressed/image_raw raw

Visual Comparison

ZDepth (This package)

With zdepth_image_transport, we can get 30Hz rgb and 30Hz Zdepth.

Left: Original, Right: compressed -> decompressed

CompressedDepth (png)

Because compression of png is so slow, it causes slow down for other depth topics. (image_transport is serial process, and if one compression is slow, others will be slow down). The compression is 4Hz, so the raw depth is also 4Hz. and the decompression is 4Hz. Ofcourse, we can make it faster with lower png_level, but the compression will be worse.

zdepth_image_transport

ROS zdepth image transport plugin

zdepth_image_transport is for faster and lighter depth compression.

Zdepth is a depth compression method with zstd library.

Supported format

Currently supported formats are as below:

  • [x] 16UC1
  • [x] 32FC1

How to try

roslaunch openni2 openni2.launch
rosrun image_transport republish zdepth in:=/camera/depth/image_raw raw out:=/camera/depth_decompressed/image_raw raw

Visual Comparison

ZDepth (This package)

With zdepth_image_transport, we can get 30Hz rgb and 30Hz Zdepth.

Left: Original, Right: compressed -> decompressed

https://user-images.githubusercontent.com/9300063/199556928-821fe403-f63a-456a-a633-a407bf5fe384.mp4

CompressedDepth (png)

Because compression of png is so slow, it causes slow down for other depth topics. (image_transport is serial process, and if one compression is slow, others will be slow down). The compression is 4Hz, so the raw depth is also 4Hz. and the decompression is 4Hz. Ofcourse, we can make it faster with lower png_level, but the compression will be worse.

zdepth_image_transport

ROS zdepth image transport plugin

zdepth_image_transport is for faster and lighter depth compression.

Zdepth is a depth compression method with zstd library.

Supported format

Currently supported formats are as below:

  • [x] 16UC1
  • [x] 32FC1

How to try

roslaunch openni2 openni2.launch
rosrun image_transport republish zdepth in:=/camera/depth/image_raw raw out:=/camera/depth_decompressed/image_raw raw

Visual Comparison

ZDepth (This package)

With zdepth_image_transport, we can get 30Hz rgb and 30Hz Zdepth.

Left: Original, Right: compressed -> decompressed

CompressedDepth (png)

Because compression of png is so slow, it causes slow down for other depth topics. (image_transport is serial process, and if one compression is slow, others will be slow down). The compression is 4Hz, so the raw depth is also 4Hz. and the decompression is 4Hz. Ofcourse, we can make it faster with lower png_level, but the compression will be worse.

With zdepth_image_transport, we can get 30Hz rgb and 30Hz Zdepth.

CompressedDepth (png)

Because compression of png is so slow, it causes slow down for other depth topics. (image_transport is serial process, and if one compression is slow, others will be slow down). The compression is 4Hz, so the raw depth is also 4Hz. and the decompression is 4Hz. Ofcourse, we can make it faster with lower png_level, but the compression will be worse.
