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...

Ultrasonic Sensors in Air

Ultrasonic Sensors in Air are Intelligent Sensors, which use wave-propagation phenomena in air to measure physical or chemical variables. With accordance to the influence principle, two main types of ultrasonic sensors can be differentiated. Propagation-Pafh Sensors decode changes on propagation to get a fast measurement of temperature, pressure variations or gas concentration. Most important a...

Crop/weed discrimination in simulated images

In the context of site-specific weed management by vision systems, an efficient image processing for a crop/weed discrimination is required in order to quantify the Weed Infestation Rate (WIR) in an image. This paper presents a modeling of crop field in presence of different Weed Infestation Rates and a set of simulated agronomic images is used to test and validate the effectiveness of a crop/w...
