Since the digital mode file information of the STL format information is triangular information, according to the characteristics of the triangle, the endpoint information at this time includes three The endpoint is the first endpoint, the second endpoint, and the third endpoint, respectively.

[0068] It will be appreciated that the point cloud density information refers to the resolution information of the image formed by the point cloud data, and the point cloud density information is positively correlated with the resolution information, that is, the larger the density of the point cloud, the higher the image resolution, but in turn, The lower the point cloud density, the lower the corresponding image resolution, the points information refers to the number of points after the triangular crossings of the digital module file information.

[0069] In the specific implementation, when the digital-to-mode cloud converter is the target format information, the digital display is obtained, and the corresponding point information is obtained according to the point cloud density information and the digital mode file information.

[0160] In an embodiment, the conversion module 40 is further configured to store the target point cloud coordinate information to a target array, and save the target array to a preset local database; if it is not completed within the preset time period Saving the target array, uploading the target array to the target cloud service to store the target cloud service to the target array.

[0161] Other embodiments of the conversion device of the object number of the present invention or a realization method may be referred to the above method embodiments, which is not in a sacrifice.

[0162] In addition, it is to be noted that in this article, the term "comprising", "comprising" or any other variable is intended to encompass non-exclusive contained contained, so that the processes, methods, articles, or systems including a series of elements include not only those Features, but also other elements that are not explicitly listed, or include elements inherent to such processes, methods, items, or systems. In the absence of more restrictions, the elements defined by the statement "include a ...", and there is no additional same elements in the process, method, article, or system including the element.

[0163] The above-described embodiments of the present invention described only for describing, and does not represent the advantages and disadvantages of the embodiment.

[0164] Through the description of the above embodiments, those skilled in the art will clearly understand that the above-described embodiment can be implemented by means of software plus necessary general hardware platforms. Of course, you can pass hardware, but in many cases, the former is better. Embodiment. Based on this understanding, the technical solution of the present invention essentially contributes to the prior art to reflect in the form of a software product, the computer software product stores in a storage medium (such as read only memory (Read Only Memory) , ROM) / RAM, disc, optical disc), including several instructions for enabling an end device (mobile phone, computer, digital to digitally moving conversion, or network device, etc.) to perform various embodiments of the present invention Methods.

[0165] The above is only the preferred embodiments of the present invention, and is not limited to the patent scope of the present invention, and an equivalent structure or equivalent process transform is used to use the specification of the present invention and the accompanying drawings, or use directly or indirectly in other related technical fields. The same is included within the patent protection range of the present invention.
