    Hi Enoxsoftware.,
    I am trying to use BOWImgDescriptorExtractor,
    when I try to initialise the class
    pMATCHER = DescriptorMatcher.create( DescriptorMatcher.BRUTEFORCE );
    BOWImgDescriptorExtractor bowDE = BOWImgDescriptorExtractor.__fromPtr__(pMATCHER.getNativeObjAddr());
    Unity editor crashes and even if I compile and run the executable.

    I am using with OpenCVForUnity 2.5.5.and Unity 2020.3.25f

    Thank you very much for reporting.
    OpenCV Java 4.8.0 does not seem to be able to use BOWImgDescriptorExtractor at the moment. This seems to be an error in creating the wrapper.
    https://stackoverflow.com/questions...-bowimgdescripterextractor-compute-in-android
    OpenCVForUnity is a clone of OpenCV java 4.8.0. So the BOWImgDescriptorExtractor class is currently unavailable.
    I am currently investigating if this issue can be corrected.

    Hello everyone, I would like to try this tool but I wonder if it is possible to use more than one camera, I have searched the internet and I have seen that it is but I cannot find an implementation in unity3d. I'm thinking of using a combination of character pose estimation and ArUco marks, the idea is to use it for motion capture. If possible I have some questions:

    -Is it possible to use two cameras for character pose estimation? Sometimes there are limbs not visible from one camera.

    -What is the minimum size for the ArUco marks? I know it is relative to the distance from the camera, I will be using it approximately 5 meters away.

    -Can I use a previously recorded video instead of real-time video capture?

    In the case of restoring an image that has been distorted by perspective, it is easier to use the cv2.warpPerspective method than the cv2.remap method.
    I think the DocumentScannerExample code included in OpenCVForUnity's Example may be helpful.

    I try to use getperspective and warp per spective. But some point is not linear.I want to get every point transform to
    straight line.I found some Example use griddata from python.It like Interpolate.I don't know.How It use in Opencvforunity?

    The following issue has been reported in Unity's ISSUE TRACKER.
    https://issuetracker.unity3d.com/is...s32-returns-black-pixels-when-in-webgl-player

    Most likely this issue is the cause. Could you also try building with Unity2021?

    I have confirmed that I can use multiple cameras by attaching WebCamTextureToMatHelper.cs to multiple game objects.

    -Is it possible to use two cameras for character pose estimation? Sometimes there are limbs not visible from one camera.
    Yes, it is possible.
    -What is the minimum size for the ArUco marks? I know it is relative to the distance from the camera, I will be using it approximately 5 meters away.
    Probably depends on the resolution of the camera and the type of marker. You can try ArUcoExample with the Free Trial Version.

    -Can I use a previously recorded video instead of real-time video capture?
    Yes, it is possible.

    Thanks for the report.
    We have confirmed the broken download link issue for the colorization model. This will be fixed in the next version.
    Please download and place the model directly from the following URL.

    Hello, I've been using blob detection and would like to limit the area of the mat that's analyzed because the relevant blobs will only ever show up in a certain area (bottom two thirds and left two thirds). How would I do this?

    Thanks for your work and updates on such a great tool!

    If you want to apply processing only to a specific area, you can use the submat.
    Code (CSharp):
    1.  
    2. Mat imgMat = new Mat(imgTexture.height, imgTexture.width, CvType.CV_8UC1);
    3. Mat imgSubMat = imgMat.submat(new OpenCVForUnity.CoreModule.Rect(0, 0, 400, 300));

    Dear All,

    I wanted kindly to ask for help in a probably simple situation.
    I have a live lidarscan import and want to track the blobpoints.
    Its the RPLidar Wrapper from this Link:
    https://github.com/zcyemi/Rplidar-Unity

    What I have now is a RenderTexture from a camera that contains shows the live moving points.
    In the SimpleBlobTrackExample there is only a Texture2D input and I am very unexperienced to decide, if I am choosing the right Example to develope from and if this is the right example what would be the best way to import my RenderTexture to Texture2D.

    I want to try to code it as efficient as possible and really do a simple blobtrack (with custom settings in "how many points form a blob" or "how far away they could be until seen as two blobs" etc.)

    Am I right in using this plugin I bought in hope to develope this further or should I choose a different approach?

    Thank you very much for any help :)

    Unfortunately, I am not familiar with SimpleBlobTracking.
    The following example is a good reference on how to convert from RenderTexture to Mat.

    Hello EnoxSoftware,

    I am trying to build a simple ArUco tracker app for the Pico 4 headset, but I am running into some issues with the camera calibration. The current version I am building only supports windows for now, and is run within the Unity Editor with a Logitech camera plucked in to my computer. I am trying to create a script which calibrates the camera using a chessboard that is 9 x 6, but I'm running into some problems with the object points for the chessboard. When running the script with a single image (I load the images from the resource folder), it works fine, but when I introduce multiple images of the chessboard and try to calibrate the camera, I get an error which states:

    "
    CvException: CvType.CV_32SC2 != m.type() || m.cols()!=1
    Mat [ -1*-1*CV_8UC1, isCont=False, isSubmat=False, nativeObj=0x1878363727248, dataAddr=0x0 ]
    OpenCVForUnity.UtilsModule.Converters.Mat_to_vector_Mat (OpenCVForUnity.CoreModule.Mat m, System.Collections.Generic.List`1[T] mats) (at <77eb57f92a3c44f2980005bd33b70669>:0)
    OpenCVForUnity.Calib3dModule.Calib3d.calibrateCamera (System.Collections.Generic.List`1[T] objectPoints, System.Collections.Generic.List`1[T] imagePoints, OpenCVForUnity.CoreModule.Size imageSize, OpenCVForUnity.CoreModule.Mat cameraMatrix, OpenCVForUnity.CoreModule.Mat distCoeffs, System.Collections.Generic.List`1[T] rvecs, System.Collections.Generic.List`1[T] tvecs) (at <77eb57f92a3c44f2980005bd33b70669>:0)
    MarkerBasedARExample.WebCamTextureMarkerBasedARExample.Calibrate_Camera () (at Assets/MarkerBasedARExample/WebCamTextureMarkerBasedARExample/WebCamTextureMarkerBasedARExample.cs:149)
    MarkerBasedARExample.WebCamTextureMarkerBasedARExample.Start () (at Assets/MarkerBasedARExample/WebCamTextureMarkerBasedARExample/WebCamTextureMarkerBasedARExample.cs:84)
    "

    It seems to only be an error when I try to add more than one "objectPointsMat" to the "objectPoints" list. I think it is because it expects only one element within the objectPoints since it needs to be the same as size "imagePoints" (I'm guessing at least). I've tried to change the "CvType" to several different values that it seems the function expects, but without any luck. I was hoping you could show me how to get it working, or at least how I can get around this problem and calibrate my camera using a chessboard with several images instead of just a single one.

    Best regards,
    MANND

    Hi, MANND

    OpenCVForUnity ships with an "ArUcoCameraCalibrationExample" as an example of calibration using ArUco, have you tried that? You can load and test multiple images by enabling the Image Input Option.

    Hi EnoxSoftware,

    I thought the camera calibration example only supported ArUco marker boards, but after further inspection, I can see that it also supports chessboard, which is fantastic! I'll give it a try and get back you to you with the results.

    Sorry for the late reply, and thank you so much for the help.

    Best regards,

    Hi!

    I would like to ask if this plugin is compatible with the "rapid" module of opencv to make use of silhouette detection?
    If not, what would be the best alternative to achieve a 3D alignment by processing the camera frame and obtaining enough info to place a 3D model aligned with the real world object?

    Best regards!

    Dear Enox,

    My project is for Mobile and WebGL and I just noticed in your documentation, in WebGL, videos is quite lacking.

    *1 VideoCapture (int index) and open (int index) is not supported.

    More and more unity games and apps are being published to WebGL and this is a big blocker not be able to use Video in Webgl.

    Can I make a request for this feature to be added.

    Cheers

    On the WebGL platform, OpenCVForUnity does not support the VideoCapture class API for retrieving webcamera image, but does support the API for loading video files. If you want to get webcamera image in OpenCVForUnity, you can get it from WebCamTexture.

    I have tried it on my MacbookPro2015, Intel and it works fine.
    Perhaps changing the Timeout frame count to a larger value might work.

    Perhaps the build error is due to a previous version of the file remaining in the project. Could you delete the "Assets/OpenCVForUnity" folder and then re-import the unitypackage?

    Yes your right, increasing this number made it work. Awesome.

    Btw, the Posedetection with mediaPipe works but very low FPS. 18 fps on my mac in the editor and in the webgl example link, it's only 3fps. These numbers effectively means that mediapipe pose detection is not useable in a real project.
    Is there a way to increase the FPS to 30 ? Normally mediapipe pose detection is quite fast outside of unity.

    The OpenCVForUnity dnn module Example is a port of the Example from the model_zoo repository.
    https://github.com/opencv/opencv_zoo
    I cloned the model_zoo repository and ran demo.py and compared it to the fps when run in OpenCVForUnity, and it was about the same fps.

    Can you suggest some options on how the FPS can be improved?

    First of all, frame skip is an effective way to improve FPS.
    You can easily try frame skipping with the ImageOptimizationHelper component. Please try the attached file.

    Hi Enox, thank you very much for the great work you're doing!
    I am facing a rather tough issue and I hope you can help me with this. I have the OpenCV and DlibFaceLandmarkDetector assets as well as the FaceMaskExample asset in my Unity 2022.2.0f1 project. I am trying to get the Texture2DFaceMaskExample scene to work in a WebGL build with a public URL containing an mp4 video file instead of the dance_mjpeg file contained in the StreamingAssets folder. This is not a CORS issue as the mp4 video url does play when using Unity’s VideoPlayer component in both editor and WebGL build. However, when I change the VideoCaptureToMatHelper.cs script line 395 to fullPath = "http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4"; the mp4 video plays in the editor with the facemask filter but not in the WebGL build which says ErrorCode: VIDEO_FILE_CANT_OPEN. Can you please help me so I can use the Texture2DFaceMaskExample scene with video's from URL's? Thank you
