The invention discloses a spatial displacement and strain measurement device and method based on a CCD camera, comprising a CCD color camera, a first beam splitter, a second beam splitter, a first reflector, a second reflector, and a third reflector; The first reflector, the first beam splitter and the second beam splitter form the first light path, the second reflector and the first beam splitter form the second light path, and the third reflector, the second beam splitter and the first beam splitter The beam splitter forms the third light path; the first light path, the second light path and the third light path all enter the CCD color camera; the CCD color camera is used to pass through the first light path, the second light path and the third light path shoot. The device of the present invention has a simple structure and does not need any synchronous trigger device to realize synchronous data acquisition, which is equivalent to using three CCD cameras to shoot from three directions, making the calculation results more accurate, and the present invention has no influence on the shape of the surface of the measured object. Restricted, flexible application.

The invention relates to a novel alcohol degree detection method and apparatus, especially relates to an detection method and apparatus based on a color sensitive material, wherein the detection method and apparatus are used to detect the alcohol degree during the fermentation process in real time, and belongs to the fields of fermented product raw material utilization and quality control. The apparatus comprises an upper computer, three CCD cameras, a LED integrating sphere light source, a base, a gas reaction chamber, an air inlet, an air outlet, a vacuum pump, a gas collecting probe with a special filter screen, and a temperature sensor. After the gas collected by the gas colleting probe reaches the gas reaction chamber, the gas reacts with the color sensitive material sensor arrays, which are adhered on the polyvinylidene difluoride membrane in the array area of a gas sensor; the color sensitive material is sensitive to alcohol, and thus the alcohol degree can be determined by watching the color change after the color sensitive material reacts with ethanol. The provided method and apparatus has the advantages that the operation is simple and convenient, the method is intelligent; the apparatus is simplified and is convenient to move; at the same time the detection system cost is reduced; and furthermore, the provided apparatus can be used to detect liquid alcohol and semi-solid alcohol.

The invention relates to a small multiband polarization imaging system with an automatic filter wheel. The small multiband polarization imaging system is characterized by comprising the double-layer filter wheel, three charge coupled device (CCD) cameras, a motor system, a laser range finder and a computer, wherein polarizing films are arranged at the fronts of the three CCD cameras; the double-layer filter wheel is arranged between the polarizing films and a shot scene and is controlled by the motor system; the three CCD cameras output a shot image to the computer to be processed; the laser range finder outputs measured distance signals to the computer; the computer geometrically corrects the image and computes parameters of the polarized image according to information of the laser range finder, and after polarization multiband is acquired, the computer transmits signals to the motor system so as to control rotation of the double-layer filter wheel. The image is quickly acquired by controlling rotation of the motor, and the system also has functions of image preprocessing, storage and communication, so that purposes of stably and reliably working and saving labor and financial resources can be achieved.

The invention discloses an irregular object volume measurement method based on Freeman chain code detection. A system is calibrated so as to acquire a pixel equivalent of the system; three CCD cameras are used for respectively acquiring original images of a to-be-measured object in an over-looking direction, a left-looking direction and a right-looking direction, and maximal peripheral length image coordinate parameters of the to-be-measured object are acquired via the over-looking image; based on the over-looking maximal length pixel number, measurement ranges corresponding to the left-looking image and the right-looking image are divided, a shape from shading method is used for calculating the height of each pixel point of the left-looking image and the right-looking image, a Freeman chain code is used for carrying out boundary detection on the left-looking image and the right-looking image respectively, coordinates of the boundary point are calculated, a Green formula is used for calculating the area surrounded by the boundary, the volume of the first layer is obtained through product between the area and the minimal height value, and the volume of the entire object is finally acquired according to the position of secondary small height value pixel points. The invention provides an accurate non-contact volume measurement method, the measurement speed can be quickened, and the production efficiency is improved.
