Description: 一、使用TCP协议传输数据。理由：稳定性好。
二、使用字节数据流进行传输，理由：
A:VB的String存在自动Unicode转换问题，影响速度；
B:可以直接发送8位字节数据，不需要使用Base64编码，从而减少了编码时间。
三、使用GIF-LZW压缩算法压缩图像。理由：
A:行程编码、Huffman压缩算法压缩率太低；
B:JPEG压缩算法需要太多位运算，且运算量大（有专门MMX优化算法），不利于VB实现；
C:GIF-LZW压缩算法压缩率较好，且我已想出VB语法下高效GIF-LZW压缩/解压算法。
四、使用“有序抖动”算法进行 色彩量化。理由：“有序抖动”处理的结果具有一定规律性，有助于LZW类算法压缩。-First, use the TCP protocol to transmit data. Reason: better stability.
Two, the use of byte data stream for transmission, the reasons:
A: VB s String existence automatic Unicode conversion question, effects of speed
B: can directly send 8-bit byte data, Does not need to use Base64 encoding, thereby reducing the encoding time.
Three, the use of GIF-LZW compression algorithm for image compression. Rationale:
A: Run-Length Coding, Huffman compression algorithm compression ratio is too low
B: JPEG compression algorithm required too many bit computing, and computing a large quantity (MMX has specialized optimization algorithm), VB is not conducive to implementation
C: GIF-LZW compression algorithm compression ratio is better, and I have come up with efficient under VB grammar GIF-LZW compression/decompression algorithm.
Four, use the "orderly jitter" algorithm for color quantization. Rationale: "orderly jitter" must deal with the results of reg Platform: |

Description: Bundler是一个采用C和C++开发的称为sfm（struct-from-motion）的系统，它能够利用无序的图片集合（例如来自网络的图片）重建出3D的模型。最早的版本被用在Photo Tourism的项目上。
Bundler的输入是一些图像、图像特征以及图像匹配信息，输出则是一个根据这些图像反应的场景的3D重建模型，伴有少量识别得到的相机以及场景几何信息。系统借用一个由Lourakis 和Argyros提供的称为Sparse Bundle Adjustment的开发包的修改版，一点一点递增地重建出图像场景。Bundler已经成功的应用在许多网络相册系统，尤其是一些建筑相册里。
-Bundler is a structure-from-motion (SfM) system for unordered image collections (for instance, images from the Internet) written in C and C++. An earlier version of this SfM system was used in the Photo Tourism project.
Bundler takes a set of images, image features, and image matches as input, and produces a 3D reconstruction of camera and (sparse) scene geometry as output. The system reconstructs the scene incrementally, a few images at a time, using a modified version of the Sparse Bundle Adjustment package of Lourakis and Argyros as the underlying optimization engine. Bundler has been successfully run on many Internet photo collections, as well as more structured collections.
