Hi, i bought intel realsense depth camera D415.
Now i am trying to cut point cloud, .ply file as a single object.
I want to save the img what i clicked and drop out as a single cloud point file.
I drop out the image what i want using opencv, but when i save the ply file by using (points.export_to_ply) this code, the whole screen point cloud file saved as file.
I searched and find the answer was try to cut depth frame first, and cut color frame.
I tried to cut frame as roi, but it doesn't work.
they said try to use following code.
aligned = align.process(frames)
color_aligned_to_depth = aligned.first(rs.stream.color)
xmin, xmax, ymin, ymax = 100, 200, 100, 200 # BB
depth_frame = frames.first(rs.stream.depth)
points = pc.calculate(depth_frame)
w = rs.video_frame(depth_frame).width
h = rs.video_frame(depth_frame).height
verts = np.asanyarray(points.get_vertices()).view(np.float32).reshape(h, w, 3)
roi = verts[ymin:ymax, xmin:xmax, :]
I want to cut point cloud file...
I wish i could find a way to cut it out point cloud file.
Plz do not recommend PCL, i already tired, but faild to build.
Let me know the way on Python.
Thanks.
