A kind of data processing equipment (100,200) determines the heart rate information about object of interest (605) according to time correlation sensing data (110), the time correlation sensing data includes physiological sensor data (114), the physiological sensor data includes heartbeat component and at least one motion artifacts component, and the time correlation sensing data further includes motion sensor data (116). Reconstruction unit receives the physiological sensor data (130) of removal artifact and the physiological sensor data of the removal artifact is decomposed into the physiological sensor data component (145) of multiple removal artifacts of associated component amplitude, and the heartbeat component data (150) of reconstruction is provided as to the combination of at least two component subset with highest component amplitude in the physiological sensor data component (145) for removing artifact. Heartbeat analytical unit receives the heartbeat component data (150) of the reconstruction and determines that heart beat interval as the heart rate information, and provides heart rate information signal (170) based on identified heart rate information according to the heartbeat component data (150).
