摘要

摘要: 利用图像处理技术，可对豆砾石针片状颗粒含量进行测定。但在采集豆砾石厚度信息时，对于平面摆放的豆砾石，传统的采集方式只能逐行多次采集，导致检测效率低、无法快速对其进行评价。为提升检测效率，设计了一种阶梯状摆放策略，从不同角度拍摄两张照片，结合IPP（Image-Pro Plus）软件，从而高效获取豆砾石的关键尺寸信息，并通过修正系数消除因豆砾石与摄像头距离不一导致的误差。通过图像处理软件实测豆砾石颗粒的针片状含量，并与传统的游标卡尺方法进行对比分析，研究结果表明：（1）采用阶梯式摆放设计可快速获取豆砾石尺寸信息，通过系数修正后，其信息更加真实有效，提高了整体检测效率；（2）使用IPP软件得出的针片状颗粒含量，其误差控制在允许范围内。

Abstract: Image processing technology allows for the determination of needle-shaped and flake particle content in pea gravel. However, when collecting the thickness information of pea gravel, the traditional collection method can only collect the pea gravel placed on the plane line by line many times. Aimed at the problem of low detection efficiency and unable to evaluate it quickly caused by the inconvenience of this acquisition method, a stepped placement strategy was designed, which took two photos from different angles, combined with IPP software (Image Pro Plus), to efficiently obtain the key size information of the gravel, and eliminate the error caused by the different distance between the gravel and the camera through the correction coefficient. The needle and flake content of pea gravel particles was measured by image processing software and compared with the traditional vernier caliper method. The results show that: (1) The step layout design can quickly obtain the size information of pea gravel, and after the coefficient correction, the information is more authentic and effective, which improves the overall detection efficiency; (2) The error of needle flake particle content obtained by IPP software is controlled within the allowable range.
