wrong mesh volume with certain bias value

[friendly-code-bot]

Hi ,

i try to use your amazing work to estimate a person volume by using the fitted SMPL Mesh. I was able to transform the Mesh in my respective camera coordinate system. I calculate for each body region (head, hands, arms, legs etc.) its respective volume and sum them up. I am using the world coordinates from the transformed mesh. A render to the image matches the persons silhouette.

But I found that different persons with different overall mesh representation seem to contain all similar volume of +- 0.05m^3.

It is crucial for my work to have a relatively good estimation of the persons volume but it seems that using the SMPL model wont be a good way to do this.

Could you give me ideas? Is this conversion from the SMPL Mesh to my camera coordinate system correct ? I feel it could be a scaling issue. I hope you could help me out.
