The invention relates to the field of electronic health detection, and discloses a non-contact type automatic heart rate measurement system and a measurement method. The non-contact type automatic heart rate measurement system adopts a non-contact mode to remotely collect video data of a measured person and performs data conversion to realize automatic heart rate measurement, and is characterized by comprising a video collection module, a framing extraction ROI (region of interest) module, a primary color component separation module, a time-domain signal generation module, a blind source separation module, a signal screening module and a heart rate analysis module. Compared with the prior art, the non-contact type automatic heart rate measurement system and the measurement method are based on an automatic face track and blind source separation technology, adopt a noninvasive and non-contact type remote physiological signal detection method, overcome influence of motion artifact in video record, has motion tolerance, is high in measurement accuracy, and can perform heart rate measurement automatically and simultaneously.
