We have been doing a lot of experimenting with various airplane and camera configurations for small Unmanned Aerial Systems (sUAS). We are very interested in the effect of camera quality on metric analysis. For example, does a better lens yield a more accurate surface model when extracting a dense image matching point cloud using an application such as Pix4D? What about the quality of the camera sensor? Since, as a general rule of thumb, a larger sensor (pixel size, not number of pixels) yields a high signal to noise (SNR) ratio, surely this results in a more accurate point cloud. Our current experiments (see Figure 1) revolve around overall camera speed and synchronization.
