cam

cam is a package for Go that provides a high level api (similar to net/http) and a small set of plugins for working with camera frames. For the device communication, implementing the Device interface, we use GoCV and OpenCV, more can be easily added. Contributions are welcomed.

Dependencies

• For the gocv device implementation you will only need OpenCV installed. You can see instructions for installation on the opencv docs and in the GoCV page.

Installation

go get github.com/mvrilo/cam

Example

package main

import (
	"image"
	"image/color"
	"log"

	"github.com/mvrilo/cam"
	"github.com/mvrilo/cam/middlewares/pixelize"
	"github.com/mvrilo/cam/middlewares/window"
	"gocv.io/x/gocv"

	_ "github.com/mvrilo/cam/gocv"
)

func main() {
	cam.Use(pixelize.New(32))
	cam.Handle(func(f cam.Frame) {
		text := "hello world"
		blue := color.RGBA{0, 0, 255, 0}
		data, ok := f.Data().(gocv.Mat)
		if !ok {
			return
		}
		gocv.PutText(&data, text, image.Pt(200, 200), gocv.FontHersheyPlain, 10, blue, 8)
	})
	cam.Use(window.New("cam example"))
	log.Fatal(cam.ListenAndServe(0, nil))
}
