中文摘要	in recent years, with the development of positioning algorithm and fpga, to achieve the camera positioning based on real-time implementation, rapidity, accuracy of fpga has become a possibility by way of in-depth study of embedded hardware and dual camera positioning system, this thesis set up an infrared optical positioning system based on fpga and sopc system, which enables real-time positioning to mark points in space. thesis completion include: uses a cmos sensor to extract the pixel of three objects with total feet, implemented through fpga hardware driver, visible-light led, used here as the target point of the instrument. prior to extraction of the feature point coordinates, the image needs to be filtered to avoid affecting the physical properties of the system to bring the platform, where the median filtering. coordinate signs point to fpga hardware circuit extraction, a new iterative threshold selection method for segmentation of images. binary image is then segmented image tags, which calculates the coordinates of the feature points of the needle through the center of gravity method. direct linear transformation (dlt) and extreme constraints method is applied to three-dimensional reconstruction of the plane array cmos system space coordinates. using sopc system on a chip here, taking advantage of dual-core computing systems, which let match and coordinate operations separately, thus increase processing speed. © 2014 spie.
