Webcam Texture & WebcamDevice: The type or namespace name `WebCamTexture' could not be found. Are you missing an assembly reference? #1

"Enclose the code related to the WebCamTexture class with #if UNITY_EDITOR and #endif." - could you be more specific which scripts should be removed and which parts of scripts should be enclosed?

Currently have errors when attempting to build, tried removing all examples & scripts with "WebCamTexture" but it created even more errors. Thanks for your help in advance.

Thank you for your inquiry.

Could you edit these files?

That worked, thank you!

I would like to convert this example to real-time detection, for example using the YoloObjectDetectionExample- would that be possible? What would need to be added/changed?

EnoxSoftware commented 5 years ago

Could you change all "WebCamTextureToMatHelper" in the Example code to "MLCameraPreviewToMatHelper"? https://github.com/EnoxSoftware/OpenCVForUnity/blob/master/Assets/OpenCVForUnity/Examples/MainModules/objdetect/FaceDetectionExample/FaceDetectionWebCamTextureExample.cs#L19

Tried it but didn't seem to work? I got all these errors - would you know how to resolve? Thanks so much for your help! EnoxOpenCVML

EnoxSoftware commented 5 years ago

Could you add the following line to example code?

using MagicLeapWithOpenCVForUnity.UnityUtils.Helper;
using UnityEngine.XR.MagicLeap;
arlady commented 5 years ago

OK - did that and now I get this: WebCamTextureToMatHelper' is an ambiguous reference betweenOpenCVForUnity.UnityUtils.Helper.WebCamTextureToMatHelper' and `MagicLeapWithOpenCVForUnity.UnityUtils.Helper.WebCamTextureToMatHelper'

still same errors. Just to be sure- I want to have the same scene as OpenCVImageCapture except that it'll detect objects based on video feed instead of the photo feed, I don't want to detect faces, just same object classes in Yolo. EnoxOpenCVML_FaceDetection

I succeeded in building mpk with the script below. DnnObjectDetectionWebCamTextureExample.cs.txt

I succeeded in building mpk with the script below. DnnObjectDetectionWebCamTextureExample.cs.txt

And that provided you with real time object detection using video? I updated the DnnObjectDetectionWebCamTextureExample.cs to the one you provided and I keep having that same error about the MLCameraPreviewToMatHelper:

Assets/OpenCVForUnity/Examples/MainModules/dnn/DnnObjectDetectionWebCamTextureExample.cs(251,62): error CS0246: The type or namespace name `MLCameraPreviewToMatHelper' could not be found. Are you missing an assembly reference?

Really appreciate all your help! Thank you!

I'm trying to perform face detection on Magic Leap's live camera feed. Here are what I did. I attached the ML version of FaceDetectionWebCamTexture.cs and MLCameraPreviewToMatHelper.cs to the quad in this scene OpenCVForUnity/Examples/MainModules/objdetect/FaceDetectionExample/FaceDetectionWebCamTextureExample.unity. There's no error, but when I deployed to Magic Leap, the quad is simply white, I see no texture from the camera feed let alone any detection. Any idea what could go wrong? BTW, I deleted some of the folders in OpenCVForUnity/Examples/ since there are errors regarding the WebCamTexture stuff.
