Using a Camera System for the In-Situ Assessment of Cordon Dieback due to Grapevine Trunk Diseases

Figure 1

Two pairs of smartphones mounted facing the opposite rows for continuous data collection. This prototype setup also includes two action cameras and two vertically orientated phones; note that only images collected from the horizontally orientated phones were included here. Other than a companion phone to control these phones from the driver’s seat, no additional infrastructure was needed. See Figure 2 for an example image.
