I am currently using a circular path method to generate 3D models of homes. To improve the quality and accuracy of these models, especially in achieving sharper edges and minimizing errors, i are seeking input on effective parameter settings in Node ODM.
i am encountering issues where parameters like octree depth and minimum features seem to be causing holes in the model.
Could you please share your insights or suggestions on which other parameters might help improve the sharpness of edges and overall model quality, making it more error-free? Any recommendations or adjustments you’ve found effective would be greatly appreciated. Thank you!
*Note : its for a circular path where the over is almost 4 to 5 deg between images,
The Radius of circle is about 80 -100 feet, no of images taken are 80 and altitude is 90-120 feet. The camera angle is calculated dynamically on the basis if altitude and radius while the height of house or POI isn’t incorporated for now (its 0)
My recommendation (from some experience) is to use multiple passes (orbits) at varying heights.
Imagine a dome of images … various altitudes and angles. It will help alleviate holes. I have had to fly very low altitude (20 ft, if there are no obstacles) to get additional details.
Your frequency of image capture is good. 3 or 4 passes should give you good results.
sure thanks. I am having an issue that is generate modal for hilly area’s now what i want is the ground to be flat in every case, since my modal is slanted according to the ground shall i make a new topic for this
also i wanted to state that, i also take closer images of the roof, that sometimes causes holes in the roof mesh, especially if i use params. So will having orbits at different heights and altitudes, will cause problems ???
Actually i am using the modals to make a solar panel fitting app which is extremely sensitive to titlness and roof design since a light bump is also causing pitch issues.
