The invention discloses a driver heart rate and respiratory rate detection system based on a non-contact laser radar. The system comprises an in-vehicle laser radar monitoring device, an in-vehicle early warning device, in-vehicle monitoring equipment and an internet monitoring system. The laser radar can collect heartbeat frequency and breathing frequency of a driver in real time in a non-contact mode; the heart rate and respiratory rate processing control device judges whether the received value is within a normal threshold range or not; if the vehicle is not in the normal range, prompting words are sent to the interior of the vehicle through an in-vehicle early warning device, and meanwhile a warning lamp flashes; the internet monitoring system can remotely check real-time videos of the driver, historical heart rate data and alarm data of the driver are monitored through big data analysis of the internet monitoring system, and statistical analysis can be carried out on heart rate and respiratory rate alarm
