Embodiment

[0029] Please refer to Figure 1-3 , the cloud computing-based high-precision stereo vision measurement method, please refer to figure 1 ,include:

[0030] Step S100: Shoot at least three pieces of digital image data comprising a certain point to be measured by a camera and obtain the GNSS data of the camera coordinates when shooting the point to be measured; the digital image data is stored in binary, using formats such as jpeg\png\gif Digital images stored with or without compression. In practical applications, when the user uploads the GNSS measurement position of two digital images and the digital image itself to the server, the server algorithm obtains and returns the attitude position of the digital image to the mobile terminal, and the mobile terminal can use the corresponding attitude The file measures point projections (i.e., pixel positions of points in the images) in two-dimensional space stored in two digital images.

[0031] Due to the current insufficient comp...

Abstract

The invention discloses a stereoscopic vision high-precision measurement method based on cloud computing, and a storage medium. The stereoscopic vision high-precision measurement method comprises thesteps of: shooting at least three pieces of digital image data containing a certain point to be measured by means of a camera and acquiring GNSS data of coordinates of the camera when the camera is shooting the point to be measured; calculating to obtain attitude and position data of the digital image data based on the digital image data and the GNSS data; and acquiring three-dimensional coordinates of the point to be measured based on the attitude and position data. The stereoscopic vision high-precision measurement method obtains the attitude and position data of the digital image data through acquiring the digital image data containing the point to be measured and GPS data, obtains the real three-dimensional space coordinates of the point to be measured through bundle adjustment based on the attitude and position data, expands the application range of the camera, adopts simple measuring equipment, and can also measure the point to be measured under the shielding condition.

Description

technical field [0001] The invention relates to the field of position measurement, in particular to a cloud computing-based stereo vision high-precision measurement method and a storage medium. Background technique [0002] The emergence and development of 3D laser scanning technology, also known as real scene replication technology, provides a new technical means for the acquisition of spatial 3D information. It adopts a non-contact high-speed laser measurement method to obtain the geometric data and image data of complex objects, and finally the post-processing software processes the collected point cloud data and image data and converts them into spatial position coordinates or models in the absolute coordinate system. Output in a variety of different formats to meet the data sources of spatial information databases and the needs of different applications. [0003] The 3D points in the space scanned by the existing 3D laser point cloud are not transparent, a large number...
