Our software uses your lens height as a guideline to generate the measurements for your room dimensions inside your 3D model and 2D floor plan. Our platform will automatically set your lens height to 1700mm / 5.5 ft and we are still able to create your measurements if you don't know your lens height, however if we have the exact distance used when taking your 360 photos we are able to achieve up to 98% accuracy in your 3D model and 2D floor plan dimensions.
