Hi everyone,
I used rostopic echo and received a bunch of PointCloud2 Msg, but I have a hard time understand it especially for the "data" array.
Here is one example:
header:
seq: 0
stamp:
secs: 1527193450
nsecs: 13024000
frame_id: "velodyne"
height: 1
width: 1
fields:
-
name: "x"
offset: 0
datatype: 7
count: 1
-
name: "y"
offset: 4
datatype: 7
count: 1
-
name: "z"
offset: 8
datatype: 7
count: 1
-
name: "intensity"
offset: 16
datatype: 7
count: 1
is_bigendian: False
point_step: 32
row_step: 32
data: [218, 49, 151, 64, 105, 199, 245, 64, 50, 184, 192, 63, 0, 0, 128, 63, 1, 0, 64, 64, 252, 127, 0, 0, 182, 0, 0, 0, 0, 0, 0, 0]
is_dense: True
I have read through the documents for PointCloud2 but did not find helpful information for understand the "data". I want to extract point coordinate as (x,y,z) from it. Looking forward to some help!
