一、隐私遮蔽

1、根据当前zoom，确定镜头的视场角

for(i =0; i <= count; i++)
	{
		if(sony_pos <= pAngleView[i+1].sonycoord)
		{
            if(sony_pos >= pAngleView[i].sonycoord)
            {
                zoomNext = pAngleView[i+1].sonycoord;
                zoomPre = pAngleView[i].sonycoord;
                viewNext_h = pAngleView[i+1].horAngle;
                viewPre_h = pAngleView[i].horAngle;
                viewNext_v = pAngleView[i+1].verAngle;
                viewPre_v = pAngleView[i].verAngle;

                AngOfView.horAngleHalf = ((viewNext_h-viewPre_h)*(sony_pos-zoomPre)/(zoomNext-zoomPre) + viewPre_h)/2;
	            AngOfView.verAngleHalf = ((viewNext_v-viewPre_v)*(sony_pos-zoomPre)/(zoomNext-zoomPre) + viewPre_v)/2;

                break;
            
            }
			
		}
	}

2、坐标转换

{
        centerX &#
