Object recognition with ultrasonic sensors

چکیده
We have recently introduced a novel approach to sonarbased object recognition for robotics. The sonar recognition system—consisting of a Polaroid sonar coupled with an A/D data acquisition board in a LINUX-based PC— uses a fuzzy ARTMAP neural network classification system to recognize objects at varying distances. In this article we report additional results in which we test systematically recognition performance using different kinds of information from the sonar echo, and different object configurations. The results strengthen our claims that sonar can be used as a viable system for real-time object recognition in robotics and other application domains.

Shape Recognition and Position Measurement of an Object Using an Ultrasonic Sensor Array
Shape recognition of a transparent object is usually difficult to perform by image processing techniques, because the major portion of the light projected onto an object passes through the object. As a result, the object cannot gain the light intensity required for image processing. Ultrasonic sensors are often utilised in situations where such optical sensors cannot be used. Moreover, systems ...

Object recognition is an important task associated to mobile robots navigation. Upon detecting any obstacle, the recognition system must be able to say which obstacle is in the robot trajectory, so that the control system is able to plan a new trajectory for the robot, deviating from the detected obstacle or following it, depending on which is the obstacle. It is normally necessary to recognize...
