Como obter o melhor modelo 3D de qualidade, incluindo texturas nas laterais do edifício, usando drone2map?

Question

<\/HEAD>Eu tenho ótimas imagens de um dji inspire para um pequeno local. Minhas imagens que são muito ortogonais ao solo produzem uma superfície 3D no drone2map, mas como você pode esperar, ao dar zoom as laterais dos edifícios não são texturizadas muito bem em comparação com os telhados. Quando incluo imagens de drone com um ângulo mais oblíquo para capturar as laterais dos edifícios, a malha 3D resultante no drone2map fica completamente confusa. Existe algum documento específico que descreva o plano de voo ideal e as vistas ortogonais vs oblíquas para produzir mapas e modelos ótimos, ou configurações diferentes no drone2map para fazer minhas imagens produzirem uma ótima superfície 3D texturizada?<\/P><\/BODY><\/HTML>

John,

If you have very high oblique images that include a lot of horizon / sky it is going to be difficult to build a 3D mesh successfully. As Ruwan mentioned above, little to no sky is best.

Drone2Map will allow you to process both NADIR and Obliques together, and users are reporting an increase in quality of their final products by doing this approach.

Thanks,

In my experience, having little to no sky in your oblique shots leads to much better modeling.

That helped a lot but there are some places in my textured mesh where its still trying to create mesh from sky. Are my images too oblique?  Would a best practice be to ensure that oblique images do not include any sky?  Also from my drone survey I have about 100 image that are very orthogonal in nature (no sky) and about 80 that are very oblique in nature (include sky).  The 2 sets are from different altitudes.  Can I process these images all together, or should I not mix like that?  Should I instead attempt to maintain a basically constant altitude for the survey?
