Hi,

I tried to run a model on oak-d without using camera. May be I'm completly wrong…

first I can run depthaidemo.py

using depthai module from: C:\Users\laurent\AppData\Roaming\Python\Python310\site-packages\depthai.cp310-win_amd64.pyd

Depthai version installed: 2.20.2.0

Setting up demo...

Available devices:

[0] 14442C10219C90D000 [X_LINK_UNBOOTED]

USB Connection speed: UsbSpeed.SUPER

Stopping demo...

=== TOTAL FPS ===

[color]: 26.8

[depthRaw]: 26.8

[depth]: 26.8

[left]: 26.1

[rectifiedLeft]: 25.4

[right]: 26.1

[rectifiedRight]: 26.1

[nn]: 26.1

[nnInput]: 26.8

Setting up demo...

Available devices:

[0] 14442C10219C90D000 [X_LINK_UNBOOTED]

USB Connection speed: UsbSpeed.SUPER

Downloading C:\Users\laurent\.cache\blobconverter\human-pose-estimation-0001_openvino_2021.4_6shave.blob...

Then I compile and run my c++. In this code I'm using a model given in openvino (omz_downloader --all)

string path("C:/Users/laurent/intel/resnet50-binary-0001/FP16-INT1/");

Net net = readNetFromModelOptimizer(path+"resnet50-binary-0001.xml", path+"resnet50-binary-0001.bin");

net.setPreferableBackend(DNN_BACKEND_INFERENCE_ENGINE);

net.setPreferableTarget(DNN_TARGET_MYRIAD);

cout << "DNN_TARGET_MYRIAD -> OK\n";

Mat img, dst;

Image2BlobParams paramMobilenet;

paramMobilenet.scalefactor = Scalar(1.0 / 58.393, 1.0 / 57.12, 1.0 / 57.375);

paramMobilenet.size = Size(224, 224);

paramMobilenet.mean = Scalar(123.68, 116.779, 103.939);

paramMobilenet.swapRB = true;

paramMobilenet.datalayout = DNN_LAYOUT_NCHW;

img = imread(samples::findFile("C:/data/VOC2012/JPEGImages/2007_002227.jpg"));

Mat blob = blobFromImageWithParams(img, paramMobilenet);

net.setInput(blob);

cout << "setInput -> OK\n";

Mat detect = net.forward();

cout << "forward -> OK\n";

I have got an error. My question is must I stop to find an answer because what i'm trying is not possible or somethong is wrong in my intalled or in my program?

DNN_TARGET_MYRIAD -> OK

setInput -> OK

Hi,
I think it can be usefull to be able to use cv::videocapture to get image from oak :

       cv::VideoCapture capture_left(0,  cv::CAP_OAK_D);
       cv::VideoCapture capture_right(1,  cv::CAP_OAK_D);
       for (;;) {
            capture_left>> frame;
            if (frame.empty())
                break;
            imshow("left", frame);
            capture_right>> frame;
            if (frame.empty())
                break;
            imshow("right", frame);
            char key = (char)waitKey(30); //delay N millis, usually long enough to display and capture input

Is somebody working on this?

Llberger · Mar 15, 2021

I hope you can find an answer in this subject
For me git submodule update --init --recursive solve this problem

Llberger · Mar 5, 2021

Brandon One clean way to do this is to use PyCharm, which makes a virtual environment for each example, so then each will have its own version.

Sorry for delay.

I don't want to use pycharm.

Now is oak-d python api is only compatible with pycharm?
What's about other environement ?

Llberger · Feb 16, 2021

Thanks for your answer

Now it works.

depth-demo is dead now

depthai_demo.py
No calibration file. Using Calibration Defaults.
Using depthai module from:  F:\Program Files\Python\lib\site-packages\depthai.cp38-win_amd64.pyd
Depthai version installed:  0.0.2.1+9b7d9364ccb94e26c8754a2e0a69b2dafe6de145
Version mismatch between installed depthai lib and the required one by the script.
                Required:  0.4.1.1
                Installed: 0.0.2.1+9b7d9364ccb94e26c8754a2e0a69b2dafe6de145
                Run: python3 install_requirements.py

I think is for the other api. 2 api is really confusing.

Thanks again for your help

I tried to run 01_rgb_preview.py and run_test error

F:\lib\depthai-python>examples\01_rgb_preview.py
Traceback (most recent call last):
  File "F:\lib\depthai-python\examples\01_rgb_preview.py", line 8, in <module>
    pipeline = dai.Pipeline()
TypeError: depthai.Pipeline: No constructor defined!

What's wrong?

When I run run_test.py I have got many errors

@GergelySzabolcs thanks first error is gone now. I certainly missed aline in doc. ( F:/lib/depthai-python/depthai-core does not contain a CMakeLists.txt file.)

Now a new one

What's wrong?
Do I need this to run first example?
in cmd window now I can ru demo

F:\lib\depthai-python>G:\Lib\depthai\depthai_demo.py

I see image and I press q but after
