Abstract: A blood pressure measuring method and system. The method includes: obtaining at least one video that captures a first body area and a second body area of a testee; extracting multiple gray scale values for corresponding images that capture the first body area and multiple gray scale values for corresponding images that capture the second body area; drawing a pulse-wave waveform of the first body area based on the multiple gray scale values of the first body area, and drawing a pulse-wave waveform of the second body area based on the multiple gray scale values of the second body area; determining a pulse-wave propagation time based on the pulse-wave waveform of the first body area and the pulse-wave waveform of the second body area; and obtaining a blood pressure value of the testee based on a corresponding relation between the pulse-wave propagation time and blood pressure.

Abstract: Embodiments of the present invention disclose method and apparatus for processing a depth image. The method comprises: obtaining the depth image and a captured image corresponding to the depth image; segmenting the depth image to obtain a plurality of segmentation units; calculating a corresponding depth reference value for each segmentation unit; determining a standard range of depth value for the each segmentation unit based on the corresponding depth reference value; and adjusting a depth value of each pixel of the depth image to the standard range of depth value corresponding to the segmentation unit in which the each pixel is located. The method and the apparatus of embodiments of the present invention can improve the quality of the depth image and cause the depth image to be easily identified.
