应用数字图像处理方法对鲍苗壳长进行图像测量。使用专业图像分析软件（Image-Pro Plus ） IPP 6.0处理度量，得到标准刻度尺单位刻度的像素长度，求取鲍苗壳长的像素长度；通过单位标定，像素转换成几何长度，得到鲍苗壳长的测量值，同使用游标卡尺测量值进行比较。比对13批组430粒鲍苗壳长数据。结果表明：基于IPP 6.0的鲍苗壳长图像测量方法和传统手工测量方法，比对试验结果一致性良好，可满足实际生产的需要，具有非接触、测量快、精度高、便于直接统计分析等特点。%A Juvenile abalone shell length measurement method was introduced in this paper and the application of digital image processing method to measure the abalone shell length was described . The standard scale pixel length of the units was obtained by using specialized image analysis software (Image-pro plus) IPP 6.0 ,and then we got the pixel length of the abalone shell .By adopting unit calibration , the measurement value of the abalone shell was obtained which compared with the measurement values obtained by using calipers .By comparing the 13 batches of 430 abalone shell length data , the experimental results had good consistency and showed that the shell length measurement of abalone images based on digital image processing method had the characteristics of non-contact ,high precision ,fast measuring speed and the measuring results could be recorded directly to facilitate data statistics and analysis .Image measurement method could meet the needs on the actual production .It was also expected to be used for the detection of the crab ,shellfish and other aquatic seedling size .
