Embodiments of the present disclosure provide a biological feature data detection method, a biological feature identification apparatus and an electronic terminal. The method includes: determining, based on a first illumination environment parameter in an ambient environment at a biological feature registration stage and a second illumination environment parameter in an ambient environment at a biological feature matching stage, an ambient illumination environment variation factor at the biological feature matching stage relative to the biological feature registration stage; and adjusting a quality influence factor of biological feature data at the biological feature matching stage according to the ambient illumination environment variation factor at the biological feature matching stage relative to the biological feature registration stage, and detecting the biological feature data at the biological feature matching stage.
