FPGA based object detecting

Pattern is renewal by following each other elements consecutively and regularly in an object or set of event. Object detecting is designation this object or event for specified categories. Objects can be detected with different methods. Nowadays, different solutions can be produced by means of developing digital methods and electronical circuit technologies. The end point of development of digital design is FPGA chip. FPGAs are programmable semiconductor devices of which consist programmable components (logic blocks) and connections. Logic blocks can be programmed to perform implementation of basic logic gates (AND, XOR, etc...), also it can be programmed in order to fulfil more complex functions of transactions (Multiplex-Decoder-Processor, etc...). In this thesis study, Xilinx Spartan 3E-100 serial and VHDL (Very High Speed Hardware Description Language) have been used as FPGA device and software language. The software of Xilinx's manufacturer is ISE Design Suite interface which has been used for testing hardware created by the interface and for trying the accuracy of the software prior to installation to FPGA. How to use the software and embedding process of the written program has been executed step by step. As FPGA based an object detecting algorithm, detecting a constant physical object and calculating distance of this physical object with ultrasonic sensor which is connected to FPGA has been achieved. Visualization of calculating data has been provided with seven segment display on FPGA.
