Abstract: A dense optical flow calculation system and method based on an FPGA (Field Programmable Gate Array) are provided. The system comprises a software system deployed on a host and a dense optical flow calculation module deployed on the FPGA. Pixel information of two continuous frames of pictures is obtained from a host end in the system, and optical flow is obtained by calculation by means of the steps such as smoothing processing, polynomial expansion, intermediate variable calculation, optical flow calculation. An image pyramid and iterative optical flow calculation can be achieved by repeatedly calling a calculation core module in the FPGA; a final calculation result is returned to the host end.

Abstract: The present invention provides a device for collecting information from face and the tongue for Chinese medicine, which includes a tank, a light source and a shooting structure. The light source and the shooting structure are positioned inside the tank, the shooting structure contains a guide column, a lifting component, a shooting component and an electrical component. The guide column and the electrical component are fixed in the tank, the shooting component fixed on the lifting component, the lifting component fixed on the guide column, which can achieve adjustment of the relative to the guide column by the electrical component. The present invention also provides a method for collecting information collection from face and tongue for Chinese medicine, which includes: 1. collect the information of the face with the camera lens perpendicular to the face plane; 2. tilt forward the camera's position while raising to the vertical plane with the tongue, collect the further information of the tongue.

Abstract: The invention provides a device for sphygmus diagnosis, including a positioning component independently fixed around one's wrist, said positioning component has a visible positioning window. Said sphygmus diagnosis device also has a sensor component which is installed in the positioning component. After assembly the sensor probe of said sensor component is located inside said positioning window. The invention has the following advantages: 1. The determinate position of pulse is accurate. 2. Avoiding the measuring position's deviation caused by the moving of the wrist. 3. Ensuring the stability when positioning component fixed around the wrist. 4. The wrist-pillow can rotate freely, which is convenient to achieve the switch between left and right hand for acquisition for pulse.
