Cloud Compare 11: Change Detection analysis
Рет қаралды 15,102
Күн бұрынThis video shows how to conduct a change detection analysis between two point clouds using two techniques: (1) the Cloud-to-Cloud distance (C2CD) and (2) Multi-scale Model to Model Cloud Comparison (M3C2).This is a very useful method to study aspects such as land cover changes, urban development, erosion, flooding, sedimentation and deposition, deforestation, changes in tree canopy and more.

Very good presentation of the C2C analysis and M3C2 analysis! The M3C2 analysis is for more advanced users but you explained it very well, it helped me a lot with writing my paper thanks!

Thanks for going over M3C2 in quite high detail. This should really help my honours project in applying or attempting to apply M3C2 for coral growths.

Hi Carlos, regarding comparing two or more Point clouds with cloud compare , i have a Lidar point cloud and i generated point cloud from Arial Photos through Agisoft and then i used Lastools to get DTM , so i want to compare the both Point clouds ,,, it means also Change Detection between the both !! PoI is very big so my Prof told me to take some places like Street , parking spot , buildings ! any recommendation

Yes you can, just use a more limited area so you have less data > this will reduce computational time

Hi, could please say what you did for both scans to be in the same survey grid?

hi love the explanation, will be using your method to complete my fyp. But I got a question, i know that there is no unit in cloud compare but heard you saying meters for the building, is this just an assumption or a method that you used to get it ? Thanks

Can you use a rhino model??

@@CarlosBartesaghiKoc great thank you. I was considering using it to compare point clouds from two different scanners.
