Problems solved by technology
It is also possible to transform the coordinates of the first data group by modifying the spatial coordinate transformation relationship, and then calculate the correlation between the converted data group and the data group to be spliced, and achieve the optimal end iteration through the correlation, but the speed of the entire iterative process is difficult. promote
It can be seen that in the prior art, the stitching of 3D imaging data has the problems of low stitching accuracy and slow calculation speed

The invention relates to the technical field of three-dimensional imaging, and provides a three-dimensional imaging data splicing method and device, electronic equipment and a storage medium, and themethod comprises the steps: obtaining initial data to construct coordinate data of the bottommost layer of a Gaussian image pyramid, and calculating the coordinate data of all layers in the Gaussian image pyramid; initializing an iteration parameter and an iteration layer in the Gaussian image pyramid, performing stepping calculation on the iteration layer to obtain a coordinate conversion matrixof an initial iteration layer, and initializing the iteration layer, including initializing the highest iteration layer to the lowest iteration layer in sequence; judging whether the coordinate transformation matrix meets a preset end condition or not; and if the coordinate conversion matrix meets the preset ending condition, taking the coordinate conversion matrix as a target conversion matrix toperform coordinate conversion on a first data set, and performing splicing fusion on the first data set and a second data set. According to the method, the iterative computation speed of the three-dimensional imaging data can be increased.
Description
technical field [0001] The present invention relates to the technical field of three-dimensional imaging, in particular to a three-dimensional imaging data splicing method, device, electronic equipment and storage medium. Background technique [0002] At present, for 3D imaging systems, due to the consideration of cost and other objective factors, the imaging field of view has its inherent limitations. To break through this limitation, different 3D imaging data need to be spliced. In the existing technology, it is usually by extracting the feature points of different data groups, and then calculating the matching relationship of different groups of data according to the feature points, and then splicing different sets of data. The splicing effect depends on the accuracy of the feature points. Selecting inappropriate or too many will reduce the splicing effect. It is also possible to transform the coordinates of the first data group by modifying the spatial coordinate transf...
