空间动态目标点坐标高帧图像测量相机

High-frame-rate Image Measurement Camera of Space Dynamic Coordinates

为了提高光学三维动作捕捉系统测量结果的动态特性,设计了高帧空间坐标测量系统。实现了高帧多运动目标空间坐标的实时测量。系统采用高帧的CMV300传感器采集图像数据,用高速大规模FPGA作为逻辑控制管理芯片,设计了一种与图像传输帧率同步的高速空间坐标测量算法。利用嵌入式千兆网将坐标测量结果快速传送到上位机实现实时三维构建显示和存储。测试结果表明:该系统运行稳定,帧率为480帧/s,计算动态MARK标志点每帧200个以上。

In order to improve the dynamic characteristic of results that the optical three-dimensional motion capture system measures,a high-frame-rate space coordinate measurement system was designed.The system realized high-frame-rate and multi-motion targets real-time measurement of spatial coordinates.The high-frame-rate CMV300 image sensor was used to generate image datas.Using high speed and large scale FPGA as logic control management chip,a high-speed spatial coordinate measurement algorithm that can synchronize with the image transmission frame rate was designed.The measurement results of space coordinate was sent to the host computer for realizing real-time construction of three-dimensional display and storage using the embedded gigabit ethernet.Accoding to the test results,the system runs stably,frame rate reaches 480 F/S and calculates more than 200 dynamic MARK targets per frame.
