M12魚眼鏡頭是一類特殊的廣角鏡頭。M12魚眼角度一般大于180°,通常安裝在安防攝像機、無人機、車載影像、多目拼接上。M12魚眼鏡頭其中的M12是指螺紋的直徑,螺距一般為P0.5。常搭配1/4英寸到1/1.8英寸CMOS圖像傳感器。
成像模式
M12魚眼鏡頭的成像效果有別與常規(guī)的M12鏡頭的。一般采用垂直內(nèi)切或者水平內(nèi)切成像模式。(模式1 Circular Fisheye、模式3 Full Horizontal)
圖像傳感器選擇
M12魚眼鏡頭一般選擇1:1或者4:3的圖像傳感器,可以最大程度的利用Sensor的有效像素。
上圖例子中的情況Sensor尺寸固定(對角尺寸)的情況下,Sensor的比例越趨近與1:1 ,可以利用的鏡頭角度越大。
上圖例子中的情況鏡頭像園尺寸固定的情況下,Sensor的長寬比例越趨近1時 ,所需要芯片面積越小。
在為魚眼鏡頭搭配圖像傳感器時盡量選擇1:1或者4:3的傳感器,不推薦16:9。結(jié)合我們客戶的案例推薦幾款常見用于魚眼鏡頭項目上的型號如:IMX183、IMX250、IMX334、IMX577、IMX274等。
M12鏡頭最大像圓可以設計到φ11mm左右,由于魚眼鏡頭的特殊性M12魚眼鏡頭的設計像園多集中在φ2.5mm~φ8mm。與之匹配的Sensor尺寸為1/4英寸到1/1.8英寸。
福州創(chuàng)安光電科技有限公司現(xiàn)有600+以上鏡頭品種,其中M12魚眼有60余款。產(chǎn)品覆蓋1/1.7英寸至1/4英寸。像園高度從φ2.6mm至φ7.7mm。
