Abstract: A pulse diagnostic device and a system of pulse diagnosis are provided. The pulse diagnostic device includes a cuff and a main monitor. The cuff includes a tube and an air bag arranged with an air path interface. A gas medium is received in the air bag. The tube is connected to the air path interface. The main monitor includes a pressure sensor and a controller. The tube extends to reach the main monitor and is connected to the pressure sensor, and the pressure sensor further connects to the controller. When the pulse diagnostic device is working, the cuff contacts an artery, the pressure sensor senses a pressure of the gas medium in the tube. The pressure sensor transmits the pressure of the gas medium to the controller. The controller obtains the pulse information and the blood pressure information based on the pressure of the gas medium.

Abstract: A method for high-precision true color three dimensional reconstruction of mechanical component. Firstly performs image acquisition: the left and right high-resolution grayscale cameras are fixed at same height and spaced at certain distance, an optical transmitter fixed between the two grayscale cameras, and low-resolution color camera fixed above optical transmitter, thus images of measured high-precision mechanical component are shot. Then performs image processing: all images are transmitted to a computer, which uses image processing to record surface information of measured high-precision mechanical component in the point cloud by high-precision true color three-dimensional reconstruction, which reflects color texture information of the surface, so as to realize the non-contact high-precision true color three dimensional reconstruction of high-precision mechanical component.
