BUG: On startup, something went wrong #3

Closed afogel closed 3 years ago

On booting up the app, if the camera does not have a person's image in the webcam image, the application will error out. We need to gracefully handle this case until a person's image is shown in the camera.

Adding a while loop before drawing the landmarks to check if the data is empty or not might prevent the bug from occurring.

After some more experiments, I think the key attribute that causes this bug is faceLandmarks within props parameter in Pose.js. In order to successfully start the app, this attribute must not be empty. A few cases:

  1. poseLandmarks, ea are occupied, but the error occurs.
  2. The app starts with only poseLandmarks, ea, and facelandmarks as landMarks. No leftHandLandmarks and rightHandLandmarks
  3. If I cover the camera after the app starts, the faceLandmarks will not be empty, but remains the same as before.

Thus, I guess faceLandmarks is the one that causes the error.
