Thanks for the video. I like your channel a lot! 2 questions please: 1) How can I measure the size of an object using a D455, and 2) How would I measure the distance between two objects/points in 3D space? Thanks!

i´m seaking you guidence please. I just started with lidar and point cloud. i want to use them to locate object from a shelf( or for a exaple from a supermarket shelf) and grab them with a robot. what are the steps that i need to perform a such task. I need from the camera the location of the Object and the i have to pass this information to the robot... right?

Hello Sir,
I'm trying to send through http the depth video flux (my idea is to send RGB + depth flux to another machine which process everything) but when i try to send it, as every value is on a uint16 i have to convert it to uint8 if i want to send something otherwise i receive a cut value (only the first 8 bit from 0 to 255 and the others bit from 65536 to 256 or cut) so have you ever try to do something like this?

Can you show how to use CUDA libraries for OpenCV for this project?

[trongatbui]

Thank you very much. May I ask how to accelarate the program with CUDA/CUDNN on Ubuntu? It seem that I cannot run the makrcnn detection in GPU although my laptop has an GPU.
Hope to see you answer

[enesschebbaki]

is it possible to achieve the same result by using depth display and not RGB (colour stream) as in this case?

[md.ashrafulalam]

I just love your videos and explanation :)

hello,

from realsense_camera import *

for some reason this import don't work with my pyrealsense2 package

[somusundram]

Nice one. Just curios. Have you tried to measure the object size using mask-rcnn? Will it able to detect shape of an object (For example : In my case i am interested to know whether it can detect card boxes, like the one from couriers)

I never worked in mask-rcnn due to time constraint. I have used depth image of RealSense to find object shapes but i rather like to have a reliable method like rcnn or YoLo to do it on various condition.

Whats is the best camera for do a ArSarndBOX?

[xinwenzhang]

A really wonderful video, I got a lot from video. Thanks!!

[wahswolf]

Excellent video, got me up to a basic understanding fast.

[muhammadtalhaejaz]

can you tell me what version of opencv you used?

[藍月-vd]

If I use intel SR300 can get same result?
Or I should change other library

[hassanyoussef]

hi thanks for the great explanation. i´m having problem with for some how it´s not been read by my computer and i can´t open it, so when i want to write mrcnn = maskRCNN i´m getting error. what do you recommend me to do?

[myhofficiel]

very useful video that explains efficiently how does this work

[EstevanCandido]

Great video! I would like to know how to use the mask extracted from Yolact to measure wear on a metallic surface, can you help me on this path?

[антонселиванов-ио]

hi, how do I get frames from a file *.bag recorded with realsense??

[jonparker]

im getting this error when i try to run


Loading Intel Realsense Camera
Traceback (most recent call last):

can someone help?

[보리타작-xs]

Can i manage to make some contents realsense camera with "Unreal Engine" ? I've figured out it can be created with Unity, but there's is no information with UE4 :)
