TVC 视觉库
用于处理，分析，指导和识别
与Microsoft C ++，C＃和Visual Basic环境兼容Linux，32位和64位
TVC 视觉库提供了全面的工具库，可用作构建机器视觉应用程序的基础。
它专为速度，易用性和精确性而设计，可为OEM和系统集成商提供具有高像素精度的视觉开发工具综合库
TVC由独立模块或捆绑包授权，每台机器的运行时，具有吸引力的定价方案。 可根据要求增强功能，移植和特殊适配
图像处理
逻辑运算，灰度和颜色变换，阴影校正，灰度形态学，几何变换，极坐标变形
// Sample code
// Rotate 30°, scale +20% around the center, with interpolation
Geometry::Rotate(XY(320, 240), XY(320, 240), 30, 1.2, Source,
Rotated, true);
// Two points shading correction with Black and White reference
Operator::Correct(Black, White, Source, Corrected, 0, 255);
图像分析
配置文件处理，直方图统计，斑点分析，区域遮罩，轮廓
// Get the trimmed gray-level mean with 10% trimming double Mean= Histogram::TrimmedMean(0.1, Source);
// Accumulate the histogram of the first (largest) blob Blobs.PixelHistogram(0, Source, Histo);
图像校准
缩放，等距，相关性，透视和失真变换
// Adjust the perspective from source to calibrated points Model.Append(XY(RawX, RawY), XY(GridX, GridY)); Model.Fit(Perspective);
// Undistort the source image, without bilinear interpolation Model.Register(Source, Calibrated, false);
边缘测量
自动边缘检测，异常值抑制，点模型拟合，强大的子像素测量
// Place a straight line measurement gauge Gauge.Beg= XY(139, 88); Gauge.End= XY(343, 87);
// Fit the line and get the angle Gauge.Detect(Source, BestStep); double Angle= Gauge.FittedAngle;
模式匹配
模型训练，子像素位置，旋转和缩放
// Train the pattern from a region of interest Source.Window(41, 170, 219, 194); Template.Train(Source);
// NGC search in the whole image with a rotation tolerance Template.MinAngle= -30; Template.MaxAngle= 30; Template.Find(Source);
几何匹配
模型训练，子像素位置，全面旋转和缩放
// Train the pattern from a region of interest
Source.Window(41, 170, 219, 194); Template.Train(Source);
// Geometric search in the whole image with a rotation tolerance Template.MinAngle= -30; Template.MaxAngle= 30; Template.Find(Source, true);
人物阅读
字体训练，去偏斜，自动分割，印刷字符识别和验证
// Load the pre-recorded font from a file OCR.Read(“Fonts\\OCR-B.fnt”);
// Perform the recognition from a region of interest Source.Window(41, 170, 219, 194); OCR.CharsRead(Source);
char* String= OCR.AsciiString;
数据矩阵码
自动代码位置，识别和解码，缩放和旋转不变量，Data Matrix，Aztec Code，QR …
// Find the Data Matrix code from the whole image bool Success= DataMatrix.Decode(Source);
// Read the decided string
