Abstract

Embodiments of the present disclosure provide a method for in-vehicle heart rate detection. The method includes obtaining, by an onboard camera, first heart rate data, and the first heart rate data is a currently detected heart rate. The method also includes determining first index data based on the first heart rate data, and the first index data is mapped to the first heart rate data by an index mapping table. The method also includes adjusting the first index data to second index data based on the historical heart rate data and determining second heart rate data based on the second index data. The method can further process the detected heart rate value, so that the heart rate value which is more stable and higher in accuracy is obtained, the consumption of computing resources is less, and the additional hardware cost is not increased.
