前段时间甲方提出明确需求让把软件国产化。稍微研究了一下那就转QT开发顺便把以前的功能代码重写一遍。 至于在Ubuntu下折腾QT、OpenCV安装事宜网上文章很多照猫画虎即可。 这个过程我发现几个好东东使得开发效率大幅提高
QT 6支持C 17里面很多C的新功能用起来更为舒爽。QT Creator中代码提示更快捷代码折叠也很准确QT Creator中文档生成更方便配合Doxygen之后自己都感觉更专业了 当然更让我高兴的是QT直接支持最新版的OpenCV以前还一直停留在2.3版。趁这个机会把OpenCV的应用功能也升级起来。 本系列文章就逐个来实现。
颜色空间
基础知识
OpenCV 中常用的颜色空间有以下几种 RGB以 RRed红、GGreen绿、BBlue蓝三种基本色为基础依据人眼识别的颜色进行不同程度的叠加俗称三基色模式。 YUVY 表示亮度U、V 表示色度。YUV 经过缩放和偏移产生 YCbCr。Cb 表示蓝色分量Cr 表示红色分量。YUV 具有亮度信息和色彩信息分离的特点。做图像识别时当图像受自然光影响较大时可以考虑选择 YUV 颜色空间。 HSV/HSBHSV 即色相Hue、饱和度Saturation、明度Value或 Brightness。色相是色彩的基本属性就是平常说的颜色的名称如红色、黄色等。饱和度是指色彩的纯度越高色彩越纯低则逐渐变灰取 0-100%的数值。明度字面意思明亮的程度即颜色深浅。 …
OpenCV实现
在OpenCV中可通过cvtColor进行颜色空间转换。cvtColor函数是 OpenCV 库中的一个图像转换函数用于将图像从一个颜色空间转换到另一个颜色空间。 它的函数原型如下
void cvtColor(InputArray src, OutputArray dst, int code, int dstCn0 )参数说明 src输入图像它可以是 Mat 类型或 vector 类型。 dst输出图像与输入图像具有相同的大小和深度。 code转换代码表示要进行的颜色空间转换。可以是以下值之一 COLOR_BGR2GRAY将图像从BGR 颜色空间转换为灰度空间。 COLOR_BGR2RGB将图像从 BGR 颜色空间转换为 RGB 颜色空间。 COLOR_GRAY2BGR将图像从灰度空间转换为 BGR 颜色空间。 COLOR_GRAY2RGB将图像从灰度空间转换为 RGB 颜色空间。 COLOR_BGRA2BGR将图像从 BGRA 颜色空间转换为 BGR 颜色空间。 COLOR_RGBA2RGB将图像从 RGBA 颜色空间转换为 RGB 颜色空间。 COLOR_BGRA2RGBA将图像从 BGRA 颜色空间转换为 RGBA 颜色空间。 COLOR_RGBA2BGRA将图像从 RGBA 颜色空间转换为 BGRA 颜色空间。 dstCn目标图像的通道数。如果为 0则根据转换代码自动确定。 该函数将输入图像转换为指定的颜色空间并将结果存储在输出图像中。注意在进行颜色空间转换时可能会进行数据类型转换和像素值范围的调整。 但实际上支持的转换代码比较多。imgproc.hpp中声明为/** the color conversion codes see ref imgproc_color_conversions ingroup imgproc_color_conversions */ enum ColorConversionCodes { COLOR_BGR2BGRA 0, //! add alpha channel to RGB or BGR image COLOR_RGB2RGBA COLOR_BGR2BGRA,
COLOR_BGRA2BGR 1, //! remove alpha channel from RGB or BGR image
