A continuación, anexo dos recortes de los ortomosaicos realizados en Pix4d fields. En el segundo recorte se evidencia una mala construcción en la unión de algunos elementos.
La pregunta es, ¿a que se debe el error, si para los dos casos los parámetros, plataforma de vuelo y cámara fueron los mismos?
El único cambio entre uno y otro es la hora de vuelo, ya que se pretendía evaluar la respuesta espectral en determinados momentos del día.
Hello Laura-Torres,
Is your project area flat or is there some elevation change? Currently PIX4Dfields is not designed to map hillsides and in areas like this you can see distortions in the orthomosaic. Our next release in the coming weeks will have an accurate pipeline option which might help in mapping hillsides. Alternatively, PIX4Dmapper will map these areas much better. At the very least I suggest increasing your overlap to between 80-90% in these areas.
Procese un ortomosaico con los mismos parámetros y obtuve un buen resultado. ¿A que se debe la diferencia en la capacidad de procesamiento de los dos conjuntos de datos, entendiendo que lo único que cambia es una franja horaria?
There are many factors that can change between different acquisition periods. Unless you are using an RTK enabled drone there can be difference in flight height due to the inaccuracies of the onboard GPS of most consumer grade drones. In addition, differences in sun angle and wind can impact the quality of your outputs as well. So it is difficult to say that the parameters are exactly the same between different acquisition periods.
