coded and non-coded target 编码和非编码元
However, as tasks for measuring large and complex objects become much more common today, a shortage of the amount of coded target in existing systems has affected the advantage of this technique to implement overall measurements.
随着大尺寸及结构复杂物体测量任务的增多,现有测量系统编码标志(也称为编码标志)总数的不足已经制约了其整体测量优势的发挥。
