This paper presents a novel technique to measure skin topography of kiwifruit. Fringe projection has been identified as a rapid, non-destructive way to extract topographical data from fruit skins. In this paper, a detailed methodology of using this technology is outlined. The captured raw data require the filtering process to separate the low frequency component from the high frequency component. A wide range of surface roughness parameters can be extracted from the accompanying proprietary software after filtering. 3D coordinates arranged as a rectangular matrix of height values can be extracted for further image analysis. An experiment on skin topography of kiwifruit has concluded that the technique is able to to quantify the skin difference from different growing environments.
