METHOD FOR MEASURING DOWNWARD INCLINATION ANGLE OF ANTENNA BASED ON LINEAR REGRESSION FITTING

Document Type and Number:

WIPO Patent Application WO/2020/098177

Kind Code:

A1

Abstract:

Disclosed by the present invention is a method for measuring a downward inclination angle of an antenna based on linear regression fitting. The method comprises the following steps: performing instance segmentation on an input original antenna image by using a deep learning method to obtain a segmented image; performing mask processing on the segmented image; performing mathematic linear modeling fitting on the segmented image after mask processing. The mathematic linear modeling fitting comprises the following steps: extracting pixel value coordinates of an antenna edge contour from the segmented image after mask processing, and intercepting a pixel value positioned at the edge of the right end of the antenna; fitting the pixel value coordinates into a straight line by means of mathematic linear modeling fitting, so as to obtain the downward inclination angle of the antenna. A downward inclination angle of an antenna is obtained through the processing on the antenna image by a deep learning network in combination with mask processing and linear fitting, thereby establishing a convenient, safe, effective and accurate antenna measuring method.
