摘要： Techniques are described for computing devices to perform automated operations related to using images acquired in a building as part of an automated generation process of a floor plan or other mapping information for the building, in some cases without using depth information from depth-sensing equipment about distances from the images' acquisition locations to objects in the surrounding building, and for subsequent use in further automated manners, such as controlling navigation of mobile devices and/or for display to end users in a corresponding graphical user interface. The automated analysis and assessment of the building images may, for example, include incrementally generating partial versions of the mapping information, determining acquisition instructions related to further acquisition of additional images and/or other types of data (e.g., to reduce uncertainty associated with portions of the partial mapping information or otherwise obtain missing data), and providing corresponding guidance in or more manners.

摘要： The present disclosure discloses a method for measuring an antenna downtilt based on linear regression fitting, including: performing image instance segmentation on an inputted original antenna image using a deep learning method to obtain a segmented image; performing mask processing on the segmented image; performing mathematically linear modeling and fitting on the segmented image subjected to mask processing; and the performing mathematically linear modeling and fitting on the segmented image subjected to mask processing including: extracting pixel value coordinates of an antenna edge contour from the segmented image subjected to mask processing, and capturing a pixel value of a right-end edge of the antenna; and fitting the pixel value coordinates into a straight line by using a mathematically linear modeling and fitting method to obtain an angle of the antenna downtilt. The angle of the antenna downtilt is obtained based on a deep learning network of an image of an antenna with reference to masking and linear fitting to establish a convenient, safe, efficient and accurate antenna measurement method.
