Description

Abstract:

              This paper is a wireless sensor network based architecture designed for the purpose of image transmission between two controlling units through CMOS camera. Wireless sensor networks are used to increase the data transmission speed. This project can be applied to any surveillance purpose. The protocol IEEE 802.15.4 is used to transmit image accurately to the monitoring section.

               Image transmission with a combined robotic application is presented in this paper. For surveillance purpose, the path of the robot has to feed initially. This robotic section runs with LPC2148 with CMOS camera with a person detection sensor and monitoring section runs with MATLAB platform. Communications between two sections are accomplished through IEEE 802.15.4.

              This wireless image transfer unit in Robot will be ready to capture any human who enters into robot surveillance region. This presence of human can be determined by the thermal heat radiation from the object and this interrupt will wake up the camera. In order to cover the entire room, the robot module can able to turn in various angle with manual and automatic control. Under the absence of human the processor will keep the camera in the sleep mode. The technique is followed in the project to reduce the energy consumption in image transmission. These methods improves the efficiency of the robot surveillance as well as energy saving. This project uses the Matlab platform for the image visualization.
