Abstract

The invention discloses a face tracking display method, the measurement accuracy of the heart rate and the respiration rate is improved by comprehensively applying a KLT tracking algorithm, an MRC algorithm, an FFT and other methods, human body signs are effectively and remotely obtained, and compared with data synchronously collected by a medical physiological monitoring vest, the face tracking display method has good consistency and is high in accuracy. According to the face tracking display method provided by the invention, the rescue robot can quickly obtain the heart rate and respiratory rate signs of the wounded at low consumption, and the intelligent level of autonomous searching of the rescue robot is improved. On the basis of the RPPG technology, in combination with the task characteristics of the rescue robot, key technical links are optimized, so that the measurement accuracy and robustness of the non-contact heart rate and respiration rate are improved, the action effect is remarkable, and the method is suitable for wide popularization.

Description

technical field [0001] The present invention relates to the technical field of face tracking and detection, in particular to a face tracking and display method. Background technique [0002] With the rapid development of robotics and artificial intelligence technology, a variety of rescue robots that perform on-site surveys and life search and positioning have come out one after another. The ability to quickly and accurately perceive the physiological parameters of the wounded has become one of the key features of the intelligence of this type of rescue robot. [0003] Traditional manual detection, wearable and other physiological parameter measurement methods are difficult to adapt to the needs of future robot autonomous search and rescue. Research and development of technical methods with front-end autonomous capabilities that can obtain the basic vital signs of the wounded in time, and then realize the active identification of the wounded (survivors), is crucial to improv...
