Greenhouse commercial horticulture in Kenya started more than two decades ago and has evolved to be a significant sector to the national economy. So far no studies have explored the spatial patterns and dynamics of the area under greenhouse cultivation. Google Earth archives alongside data from various portals provided an opportunity to study those farms’ spatial distribution. The roles of sele...

SIR WILLIAM TEMPLE, British statesman and author, was born in 1628 and died in 1699. Soon after his marriage, at the age of 27, he took up his residence in Ireland, where he is said to have "read a good deal and acquired a taste for horticulture." In 1692 appeared the second part of Sir William's essays-the "Miscellanea," which included his classical essay on gardening. "As gardening has been t...

Certain experimental horticultural operations require an autonomous vehicle capable of navigating through a field of crop plants. An image analysis system exists which can locate the crop row structure, but simple reactive control of the vehicle on the basis of this data would not be sufficiently reliable; instead a multisensor data fusion based approach is preferred. Since the vehicle must be ...

Abstract. This paper describes recognition and cutting system of sweet peppers for picking robots in greenhouse horticulture. This picking robot has an image processing system with a positioning system for two cameras and cutting a device to follow the sweet pepper by visual feedback control. A prototype robot system is introduced. Experiments of the prototype robot prove the performance of the...

This paper describes development and experiments of a picking robot for sweet peppers in greenhouse horticulture. This picking robot has an image processing system with a parallel stereovision, a camera positioning system to follow the sweet pepper by visual feedback control, and a cutting device. A prototype robot system has been made and is introduced. Experiments of the prototype prove that ...
