Ground bearing capacity has become a relevant concept for site-specific management that aims to protect soil from the compaction and rutting produced by indiscriminate use of agricultural forestry machines. Nevertheless, commonly known techniques its estimation are cumbersome time-consuming. In order alleviate these difficulties, this paper introduces an innovative sensory system based on Visible-Near InfraRed (VIS-NIR), Short-Wave (SWIR) Long-Wave (LWIR) imagery sequential algorithm...

Image registration for sensor fusion is a valuable technique to acquire 3D and colour information scene. Nevertheless, this process normally relies on feature-matching techniques, which drawback combining sensors that are not able deliver common features. The combination of ToF RGB cameras an instance problem. Typically, the these based extrinsic parameter computation coordinate transformation between two cameras. This leads loss because low resolution camera, sophisticated algorithms...
