Problems solved by technology

In another solution, the depth information corresponding to each pixel of the RGB image can be obtained through the U-Net (Convolutional Networks for Biomedical Image Segmentation) self-encoding network through deep learning to achieve the purpose of surveying and mapping. This method has low precision , the error is high and the amount of calculation is large, and it cannot be applied to the actual living environment at present

Abstract

The invention provides a surveying and mapping method for a movable platform (600), the movable platform (600) and a storage medium, the movable platform (600) carrying a photographing device (20, 40, 700), the method comprising: at a current position, changing the attitude of the photographing device (20, 40, 700) so that different parts of a target object are located at preset positions in a photographing window, and acquiring attitude information of the photographing device (20, 40, 700) (S11); and determining the size of the target object according to the current position and the attitude information (S12). A target object can be mapped on the basis of a movable platform (600) on which an imaging device (20, 40, 700) is mounted.

Description

technical field [0001] The present application relates to the technical field of movable platforms, and in particular to a surveying and mapping method for a movable platform, a movable platform and a storage medium. Background technique [0002] Engineering surveying and mapping instruments are often used in the field of engineering surveying and mapping, but they are large in size, complicated in measurement process, expensive and difficult to use for civilian use. In one solution, the three-dimensional data after stereo reconstruction can be obtained through the principle of binocular vision stereo imaging of monocular images, and then the surveying and mapping information of objects in the line of sight can be obtained; The measurement error of close objects is large, and the height of objects that cannot appear in the same picture cannot be measured. In another solution, the depth information corresponding to each pixel of the RGB image can be obtained through the U-Ne...
