摘要
对日照透射强度进行检测,对农业、经济发展起指导作用。日照透射强度检测是通过日照透射强度光图像分解,获取日照透射光有效像元分布特征的基础上进行,而传统的定义法是直接对日照透射强度光图像整体有效像元分布特征进行提取,忽略了图像存在的细节,导致检测精度差的问题。提出基于超像素直方图分解的日照透射强度检测方法。先采集日照透射强度光图像,利用超像素直方图分解方法将图像进行分解,再建立日照透射强度光图像的有效像元检测模型,得到两组标定的日照透射光直方图并进行高斯分解,获取日照透射强度检测准则,实现对日照透射强度的精确检测。仿真结果表明,采用改进方法提高了检测精确度、缩短了检测时间、降低了检测误差,为自动化气象领域提供有效的科学依据。
A detection method for transmission intensity of sunlight based on the super pixel histogram decomposition is proposed.Firstly,the sunlight image is collected,and the image is decomposed by the method of super pixel histogram decomposition.Then,the effective pixel detection model of transmission intensity for the sunlight image is built,and two groups of calibrated transmission intensity sunlight histograms are obtained and decomposed through Gaussian decomposition method,so as to get the detecting standard for transmission intensity of sunlight,and achieve accurate detection of sunlight transmission intensity.The simulation results show that the improved method can increase the detection accuracy,shorten the detection time,and reduce the detection error.
