- A simple method to get the optical centre consists to observe the coordinates of a point when it rotates along this axis. This could be achieved by drilling a small hole in the cap of the fish-eye, and to take photographs for a series of positions.

- Objectives Hemispherical photography is used to characterize the structure of canopies and measure the gap fraction directional variation to retrieve variables such as the leaf area index (LAI), the fAPAR {Jonckheere, 2004 #3541};{Weiss, 2004 #2872}. Optical systems are not perfect and at least two main characteristics are required: • The coordinates of the optical centre • The …

- In order to quantify the light conditions of a deciduous broad-leaved forest, we proposed a method to determine the threshold level of the brightness of a hemispherical photograph when converting it into a one-bit screen image. The coefficient of determination was examined for the regression between the measured ISF (indirect site factor) using the quantum sensors and the …

- Hemispherical photography is a well-established method to optically assess ecological parameters related to plant canopies; e.g. ground-level light regimes and the distribution of foliage within the crown space. Interpreting hemispherical photographs involves classifying pixels as either sky or vegetation.
