摘要
本文提出一种新型CCD高温钢坯在线测长仪，其特色是在同一象平面上采用三块线列CCD图象传感器，侧向俯视高温钢坯。在视场中，当高温钢坯出现中心平移≤±400mm和偏转角≤±15°时，能有效地测量，测长相对误差≤±0．63％，采取有效措施，在恶劣的现场条件下，测长仪能可靠地工作。
A new on-line outline length measuring instrument with CCD for hot steel slabs is proposed in this paper. The feature of this instrument is using three linear CCD image sensors in one image plane. The CCD cameras can view hot steel slab obliquely on side face of the work place, In the CCD effective view field, this instrument can measure effectively when the hot slab in within±400mm offset distance and ±15°angle of declination. Relative length error is≤±0. 63 %。Taking effective measures, this instrumment can operate reliably in bad work condition of the work place.
