关于焦距问题 #902

Open linssswww opened 1 year ago

linssswww commented 1 year ago

如何得到相机的实际的焦距？ ErrorCode::ErrorCodeType CameraManager::getOpticalZoomFactorSync(PayloadIndexType index, float &factor, int timeout) 这个函数中也只返回了factor参数，factor参数如何跟实际焦距关联起来？

相机的型号是H20N

OSDK的变焦是在接口中获取到后算的。

°°° 那这里的lensInfo.data.min_focus_length 指的是变焦相机等效焦距还是实际焦距？

是这样理解嘛？ 实际的焦距 = factor * 最小的实际焦距
