Computer Vision Measurement System for Measuring Elasticity Modulus of Straws

Line heating is an important technique for processing hyperboloidal outside plate of ship hull. To realize the automation of the line heating, the deformation rule in line heating should be researched. In this paper, the computer vision measurement technique is applied to find out the disciplinarian of linear deformation in line heating. The principle of computer vision measurement is firstly introduced in this paper. The emphases are the images collection, camera calibration, edge detection, and 3D data reconstruction. Then some key techniques for ensuring the measurement precision are presented. At last, the result of experiments is given. The experiments showed that the measurement system was valid for measuring the linear deformation of line heating.

For the pose measurement of cannon barrel, a vision method through checked plane had been proposed. To test and improve the precision of this new method without considering the hardware error and some other inextricable objective factors，derive the imaging model of the marker (checked plane) from motion model of cannon barrel and the position relative to it using variable-controlling method. Establish the computer simulation platform of vision measurement system for cannon barrel pose based on C++ Builder. The simulation experiment validate the veracity and dependability of this method.

Binocular Measurement

As the rapid progress and development of DSP technology, a new way to solve the video signal processing was accepted. At present, binocular measurement instrument are mostly based on image capture card and PC on the market, expensive and bulky. For this problem, binocular vision measurement system based on DSP has been used. The design of elementary program structure about video processing which based on DSP/BIOS was finished and verified for its real-time. The results of the experiment show that the driver can be well used in the system.
