Abstract: A method for detecting fetal blood oxygen saturation, including: using at least two detection light of different wavelengths, to irradiate a fetus in an examined pregnant woman's abdomen in a time-sharing manner and acquiring first photoplethysmography signals corresponding to the abdomen under irradiation of the respective wavelengths of detection light, and to irradiate a detection site except the examined pregnant woman's abdomen in a time-sharing manner and acquiring second photoplethysmography signals corresponding to the detection site under irradiation of the respective wavelengths of the detection light; determining a target photoplethysmography signal of the fetus that corresponds to the detection light of each wavelength, according to the first photoplethysmography signals and the second photoplethysmography signals that correspond to the detection light of each wavelength; and determining the fetal blood oxygen saturation, according to respective target photoplethysmography signals determined.

Abstract: The present disclosure provides an analyzing and processing method and device for a road. In the analyzing and processing method for a road provided by the present disclosure, a slope value of a ground surface is obtained and image data of the ground surface is collected, and then the image data is analyzed and processed by using a pre-trained landform analysis model, so as to determine a landform type corresponding to the image data. A traveling condition is then determined based on the slope value of the ground surface and the landform type, and command information is generated according to the traveling conditions.

Abstract: The present disclosure provides an exercise guidance method and an exercise guidance device. The method includes receiving myoelectric parameters of a user collected by a plurality of myoelectric sensors, determining a current exercise state of the user based on myoelectric parameters, generating exercise guidance information based on the current exercise condition, and sending the exercise guidance information to a terminal.
