- This paper presents the algorithm for target point detection using image based methods and sensor networks to monitor the accuracy control for assembling ship blocks in a ship yard area. Dimensional control of the product at all assembling level accounts for a profitable ship production. An accuracy error at each stage accumulates to a higher value which leads to low level of ship productivity. The implementation of the image based method will enhance the monitoring system to increase the ships productivity while reducing the reworks and manual adjustments. To efficiently measure the distance between two ship blocks in real time, sensor nodes are used and the data is transferred to the monitoring server by wireless network. In order to get the correct assembling position of the ship blocks, the target points of the ship blocks to be assembled together are detected and analyzed to decide the next step for the control system. Thus as the distance is received by the server, the next direction of movement is directed through simulation results of target detection and analysis. The final process of shield wedding is done once approved by the end observer.
