I am 3D mapping my car for a university project however I am having difficulty with getting no holes/gaps in the model. Specifically, I notice problems near the hood and the top part of the vehicle. There were reflections which may have contributed to the missing imagery. I have tried adding more photos (256 photos which is more than enough). When looking at the point cloud, it shows no information in those affected areas of the car.
I have used an ND 8 filter which helped but it didn’t completely resolve the issue. I have also tried adding MTPs to see if this would help, but it did not. I did not use any GCPs for this project as well, as the vehicle is small.
Please note this project was done using DJI Point of Interest intelligent flight mode then the photos were imported to Pix4D. This allowed me to fly lower than 32 feet and closer to the vehicle. I have additionally tried rendering the model in higher resolutions to see if it helped but I didn’t notice any improvement with the missing imagery. The drone used was a DJI Phantom 4 Pro V2.
Thank you for your assistance in advance. Lastly, there were I think 5 uncalibrated photos but I don’t think this would have impacted my rendering.
