摘　　要：工业线性相机在工业图像检测领域应用较广。在实际中线性相机采集到的数据饱和值关系到相机的选型以及工业检测的效果。该文以DALSA spyder3相机为例,设计了一套定时采集方法,并展开实验,将行频从最小的300 Hz开始,到极大值18500 Hz结束,每隔1000 Hz,定时30 s,逐一统计出实际的采集行数数据,同时和相同行频的理论值逐一比较,发现当相机行频达到某一值时,相机实际采集行数达到饱和,小于理论饱和值。此套定时观测方法可作为工业检测中线性相机选型的参考方法之一。In industrial image field,Linear camera can be applied to detect。In practice,linear camera can be used to collect data,the Saturation value of data was related to select the camera models and the effect of detection in industrial Field.The paper used DALSA spyder3 camera to design a timing observation experiment,it can be used to calculate 30S data collection at 1000HZ intervals,from 30HZ to 18500HZ,comparing every practical result with every same theoretical result,the experiment can be verified to emerge saturation value in a certain line frequency.The result can be applied to select one of the linear camera models.
