As discussed I have take a closer look at the project.
The main issue here is the overlap which is not meeting the requirements for such reconstruction.
Because of this your point cloud has parts that are very noisy:
Reflectance Map is obtained from DSM. The DSM is generated from the _ filtered point cloud . The filtered point cloud is generated from the densified point cloud that is generated based on the Automatic Tie points _. That being said higher the quality of the Point Cloud then higher the quality of all the other outputs.
To obtain satisfactory results for this project you will have to clean the point cloud and re-run step 3.
To clean the point cloud, you can follow the instructions that are given here.
For future flights, please consider having a very high overlap; least 85% frontal overlap and at least 70% side overlap. Flying higher is also recommended since the images suffer from fewer perspective distortions.
I hope this answers your questions.
