Metric scaling factor

depth = self.depth_head(features, patch_h, patch_w) * self.max_depth

I had a few questions regarding the max_depth value found in the metric model.

• Is this a scaling factor for the depth output?
• Does this scaling factor mean this model is essentially relative or is this just reversing an inverse scaling factor that takes place in the model?
• Should this scaling factor be tuned based on camera hardware and testing environment or is it specific to the training dataset?
• Do you still follow the Metric Bins Module found in ZoeDepth (pg. 4)?
