Paper Abstract

The traditional light-pen portable coordinate measuring machine earns the disadvantages of slow data acquisition speed and difficult mode-changing. The new type light-pen portable coordinate measuring machine is designed to overcome the shortages. On the base of CMOS image sensor, FPGA and DSP are used as the data processing core of this machine. The basic arithmetic of a picture is resolved by the FPGA, while DSP completes the modeling of this system, error compensating and other advanced arithmetic. The camera only needs to transfer the three-dimensional coordinate of the point to be measured. Wireless transport is used to take the place of USB, which can achieve a large-scale measurement. The light pen and computer of the new system are put nearby where can be operated by a single man, which can improve the measurement efficiency much.
