Unity如何调用安卓手机摄像头实现拍照和录像
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
1，要想調用攝像頭首先要打開攝像頭驅動，如果用戶允許則可以使用。
2，定義WebCamTexture的變量用于捕獲單張照片。
3，連續捕獲須啟用線程。
腳本綁定到MainCamer
實現代碼如下：
using?UnityEngine;??using?System.Collections;??using?System.IO;??using?System.Runtime.Serialization;??using?System.Runtime?.Serialization.Formatters.Binary;??using?System.Threading;??public?class?takePhoto?:?MonoBehaviour???{??????public?string?deviceName;????????????WebCamTexture?tex;??????void?OnGUI()??????{??????????if?(GUI.Button(new?Rect(10,?20,?100,?40),?"開啟攝像頭"))??????????{????????????????????????????StartCoroutine(start());??????????}??????????if(GUI.Button(new?Rect(10,70,100,40),"捕獲照片"))??????????{????????????????????????????tex.Pause();??????????????StartCoroutine(getTexture());??????????}??????????if(GUI.Button(new?Rect(10,120,100,40),"再次捕獲"))??????????{????????????????????????????tex.Play();??????????}??????????if(GUI.Button(new?Rect(120,20,80,40),"錄像"))??????????{????????????????????????????StartCoroutine(SeriousPhotoes());??????????}??????????if(GUI.Button(new?Rect(10,170,100,40),"停止"))??????????{????????????????????????????tex.Stop?();??????????????StopAllCoroutines();??????????}??????????if(tex!=null)??????????{????????????????????????????GUI.DrawTexture(new?Rect(Screen.width/2-150,Screen.height/2-190,280,200),tex);???????????}??????}????????????????????????public?IEnumerator?start()??????{??????????yield?return?Application.RequestUserAuthorization(UserAuthorization.WebCam);??????????if?(Application.HasUserAuthorization(UserAuthorization.WebCam))??????????{??????????????WebCamDevice[]?devices?=?WebCamTexture.devices;??????????????deviceName=?devices[0].name;??????????????tex=new?WebCamTexture(deviceName,300,300,12);??????????????tex.Play();??????????}??????}??????????????????????????????public?IEnumerator?getTexture()??????{??????????yield?return?new?WaitForEndOfFrame();??????????Texture2D?t=new?Texture2D(400,300);??????????t.ReadPixels(?new?Rect(Screen.width/2-200,Screen.height/2-50,360,300),0,0,false);??????????????????????????????????????????????????????????????t.Apply();??????????byte[]?byt=t.EncodeToPNG();??????????File.WriteAllBytes(Application.dataPath+"/Photoes/"+Time.time+".jpg",byt);??????????tex.Play();??????}??????????????????????????????public?IEnumerator?SeriousPhotoes()??????{??????????while?(true)??????????{??????????????yield?return?new?WaitForEndOfFrame();??????????????Texture2D?t?=?new?Texture2D(400,?300,?TextureFormat.RGB24,?true);??????????????t.ReadPixels(new?Rect(Screen.width/2-180,Screen.height/2-50,360,300),?0,?0,?false);??????????????t.Apply();??????????????print(t);??????????????byte[]?byt?=?t.EncodeToPNG();??????????????File.WriteAllBytes(Application.dataPath?+?"/MulPhotoes/"?+?Time.time.ToString().Split('.')[0]?+?"_"?+?Time.time.ToString().Split('.')[1]?+?".png",?byt);??????????????Thread.Sleep(300);??????????}??????}??} ?
