Comparison of Orchard Target-Oriented Spraying Systems Using Photoelectric or Ultrasonic Sensors

A Canopy Density Model for Planar Orchard Target Detection Based on Ultrasonic Sensors

Orchard target-oriented variable rate spraying is an effective method to reduce pesticide drift and excessive residues. To accomplish this task, the orchard targets' characteristic information is needed to control liquid flow rate and airflow rate. One of the most important characteristics is the canopy density. In order to establish the canopy density model for a planar orchard target which is...

Weed discrimination using ultrasonic sensors

Objects Localization and Differentiation Using Ultrasonic Sensors 521 Objects Localization and Differentiation Using Ultrasonic Sensors

The most crucial problem for the mobile robot navigation is obstacles detection and their localization. The determination of obstacle position should be as accurate as possible in order to support robot self-localization procedures. In order to increase its efficiency the recognition of some feature of obstacles shapes should be done. The most advanced systems use laser range-finder and vision ...

3D Gesture Acquisition Using Ultrasonic Sensors

Research and musical creation with gestural-oriented interfaces have recently seen a renewal of interest and activity at Ircam. In the course of several musical projects, issued either by from young composers enrolled in the Cursus of Composition and Computer Music or by guests artists, the Pedagogy and Creation departments of Ircam have proposed various solutions for gesture-controlled sound s...

Three Dimensional Localization of an Unknown Target Using Two Heterogeneous Sensors

Heterogeneous wireless sensor networks consist of some different types of sensor nodes deployed in a particular area. Different sensor types can measure different quantity of a source and using the combination of different measurement techniques, the minimum number of necessary sensors is reduced in localization problems. In this paper, we focus on the single source localization in a heterogene...
