golang opencv

GoCV是一个支持Linux、macOS和Windows上最新版本的Go和OpenCV的Golang包。它使得Go语言能够与最新的OpenCV生态系统兼容，并成为一个一流的客户端。你可以使用GoCV来进行图像处理和计算机视觉的开发，例如显示图片和视频。你可以使用gocv.IMRead函数来读取图片，并使用gocv.IMShow在窗口中显示图片。相应的代码示例如下：

package main

import (
    "fmt"
    "gocv.io/x/gocv"
)

func main() {
    fmt.Printf("gocv version: %s\n", gocv.Version())
    fmt.Printf("opencv lib version: %s\n", gocv.OpenCVVersion())

    window := gocv.NewWindow("Hello")
    img := gocv.IMRead("lena.jpg", gocv.IMReadColor)

    if img.Empty() {
        fmt.Printf("Error reading image from: %v\n", "lena.jpg")
        return
    }

    for {
        window.IMShow(img)

        if window.WaitKey(1) >= 0 {
            break
        }
    }
}

对于显示视频，你可以使用gocv.VideoCaptureDevice函数来打开视频捕获设备，然后使用gocv.VideoCapture的Read方法读取每一帧图像并显示。相应的代码示例如下：

package main

import (
    "fmt"
    "gocv.io/x/gocv"
)

func main() {
    fmt.Printf("gocv version: %s\n", gocv.Version())
    fmt.Printf("opencv lib version: %s\n", gocv.OpenCVVersion())

    webcam, err := gocv.VideoCaptureDevice(0)
    if err != nil {
        fmt.Printf("Error opening video capture device: %v\n", 0)
        return
    }
    defer webcam.Close()

    window := gocv.NewWindow("Capture Window")
    defer window.Close()

    img := gocv.NewMat()
    defer img.Close()

    for {
        if ok := webcam.Read(&img); !ok {
            fmt.Printf("Device closed: %v\n", 0)
            return
        }

        if img.Empty() {
            continue
        }

        window.IMShow(img)

        if window.WaitKey(1) == 27 {
            break
        }
    }
}

以上代码示例可以帮助你在Golang中使用OpenCV进行图像和视频的处理。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
