Get the 3d coordinate output of the model

[Youmimzy]

The output data seems to be different from python，where am i doing wrong?

Hi @Youmimzy, did you rescale the coordinate like FaceLandmark::getFaceLandmarkAt ?

[Youmimzy]

你好@Youmimzy，您是否重新调整了坐标FaceLandmark::getFaceLandmarkAt？

This code they output is the pixel coordinates of the image, I want to know how to operate the output three-dimensional coordinates of the world。thanks。

I think the official code does some post-processing with the output from tensorflowlite model. You can check my answer here

我认为官方代码对 tensorflowlite 模型的输出进行了一些后处​​理。你可以在这里查看我的答案

Thanks for your guidance, I solved the problem。

感谢您的指导，我解决了这个问题。

Sorry I found that I didn't seem to solve this problem. I modified my own code to get the normalized real world x, y, z coordinates through the following official code. my code： But the output doesn't seem to be correct, what am I doing wrong?

I mentioned in the link above that using the model alone cannot give you the real-world coordinates. The normalize step just gives you the image coordinate (even z axis). According to the official doc, they use a geometry module to process the model output. Maybe the python wrapper has that module included.
