中文摘要: 在数据采集及处理显示分别使用极坐标和直角坐标的系统中,实现极坐标到直角坐标的转换时,数据量大且效率不高.提出了基于现场可编程门阵列(FPGA)实现坐标转换的方法,并采用查找表方式对其进行了改进,缩小了存储器容量,提高了算法的可行性.
Abstract:Coordinate transformation is needed due to data collection using polar coordinates whiledata process or display uses rectangular coordinates． The efficiency of most transformation method islow because of the large amount of data information． A scheme of coordinate transformation usingFPGA is proposed which is improved using look up table ( LUT) ． The memory capacity is reducedand the calculation reliability is improved．
