UNDERWATER OBJECT IDENTIFICATION USING ULTRASOUND
Main Article Content
Abstract
Many research topics interest the researchers in underwater acoustic studies. Underwater object identification isone of the topics which has great scope for exploration. Ultrasonic techniques have the advantage over the hindrance created by visibility underwater. Ultrasonic sensor other than camera give the depth information which can be further used for object identification, by making an image from the depth information. The 2D to 3D conversion techniques have visual information but not depth information. This paper proposes a method for object identification using ultrasound techniques. An ultrasonic sensor is used which gives the depth information. This depth information is plotted to give a depth map. The pre-processing of the depth map is done to remove unwanted spikes.
