Lidar on Iphone - surveying of pre/post blast surfaces

[Kapil_Khanal]

Hello Ivan,
As for the working range of the device:

• For LiDAR, the range is up to 5 meters.
• For photogrammetry, there is no predefined range, and the basic photogrammetry principles should be taken into account.

Regarding the processing of LiDAR data, I would suggest you to go through the reply of Amritha in the below thread.

Is LiDAR data used during processing?

Hi @gustavhf Thank you for writing to us. To answer your question: What exactly is the LiDAR data used for in the processing? If you use a LiDAR enabled iOS device, and choose to upload your project with the “Process with depth” enabled, the LiDAR data is used directly in two ways: To estimate a more accurate scale* of the reconstruction and To fill low texture areas that photogrammetry alone is not able to reconstruct. It is important to note that visible features are still needed in all …
