Sweet Pepper Picking Robot in Greenhouse Horticulture
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...
متن کاملSweet Pepper (Capsicum annuum L.) Canopy Photosynthesis Modeling Using 3D Plant Architecture and Light Ray-Tracing
Canopy photosynthesis has typically been estimated using mathematical models that have the following assumptions: the light interception inside the canopy exponentially declines with the canopy depth, and the photosynthetic capacity is affected by light interception as a result of acclimation. However, in actual situations, light interception in the canopy is quite heterogenous depending on env...
متن کاملHow to Reduce Yield Fluctuations in Sweet Pepper?
Flushing, i.e. cyclic fluctuations in fruit yield, is an important problem in sweet pepper production. These fluctuations result from cyclic variations in fruit set. Therefore, the relationship between fruit set and plant sink and source strength was investigated in several greenhouse experiments. A decrease in plant source strength by decreasing inter-plant distance or light intensity or by le...
متن کاملModelling Dry Matter Production and Partitioning in Sweet Pepper
Models predicting growth and yield have been developed for a large number of crops. This paper describes a dynamic, mechanistic model for sweet pepper, addressing issues such as leaf area expansion, dry matter partitioning and validation. Leaf area formation and organ initiation are simulated as a function of temperature sum. Light absorption and photosynthesis are calculated for a multilayered...
متن کاملFruit Detectability Analysis for Different Camera Positions in Sweet-Pepper †
For robotic harvesting of sweet-pepper fruits in greenhouses a sensor system is required to detect and localize the fruits on the plants. Due to the complex structure of the plant, most fruits are (partially) occluded when an image is taken from one viewpoint only. In this research the effect of multiple camera positions and viewing angles on fruit visibility and detectability was investigated....
