现场可编程逻辑阵列的实时计算光斑质心检测装置
摘要：
本发明属于光电成像跟踪技术领域，涉及现场可编程逻辑阵列的实时计算光斑质心检测装置。该装置的组成有图像输入单元(21)，图像输出单元(24)、质心数据输出单元(25)，还有现场可编程逻辑阵列(31)、现场可编程逻辑阵列辅助器件单元(32)；本装置能够在几十个纳秒内解算出一幅图像的光斑质心数据，所以使得APT系统的瓶颈带宽限制由图像处理设备转移到了光电成像设备即CCD相机或CMOS相机，从而大大提高了APT系统的整体带宽。计算速度由现有的DSP嵌入式图像处理系统的每秒500幅～2000幅图像提高到每秒3000幅～10000000幅图像；设备体积由原来的200mm×300mm×30mm～300mm×500mm×800mm减小到150mm×150mm×30mm；功耗由原来的0.8w～2.0w下降到0.5w；器件数量由原来的20个～30个减少到15个。
摘要（英）：

The invention pertains to the field of photoelectric imaging and tracking technology, and relates to an in-situ programmable logic array detector for calculating in real-time the center-of-mass of a light spot. The detector comprises an image input unit (21), an image output unit (22), a center-of-mass data output unit (25), an in-situ programmable logic array (31), and a in-situ programmable logic array auxiliary device unit (32). The detector can resolute the center-of-mass data of a light spot of an image in several tens ns, makes the bottleneck bandwidth limit of APT system transfers froman image processing device to a photoelectric imaging device, namely, CCD camera or CMOS camera, hence the overall bandwidth of APT system is greatly improved. The calculation speed is improved from 500-2000 images per second with prior DSP built-in image processing system to 3000-10000000 images per second; the size of the equipment is reduced from former 200mm is multiplied by 300mm is multiplied by 30mm swung dash 300mm is multiplied by 500mm is multiplied by 800mm to 150mm is multiplied by 150mm is multiplied by 30mm; and the power consumption is reduced from former 0.8W swung dash 2.0W to 0.5 W; and the quantity of devices is reduced from former 20-30 to 15.
