A camera having blood optical imaging function, comprising: a lens, an image sensor, a main control module, a blood optical imaging algorithm module and an IP network interface module; the lens is located at the image acquiring position of the camera; the output end of the image sensor are in electric connection with input ends of the main control module and the blood optical imaging algorithm module, respectively; the main control module is in electric connection with the blood optical imaging algorithm module and the IP network interface module, respectively. The blood optical imaging algorithm is directly applied to the camera, so that the algorithm module can directly acquire original RGB data from the sensor, improving the accuracy of detection and the quality of blood vessel imaging, and achieving remote detection of the blood optical images of a face, while detecting the blood optical images of a moving face.
