The embodiment of the present invention discloses a device and method for detecting spectacle parameters based on synthetic moiré fringe technology. The device includes: a parallel light source, used to provide the device with a detection light source; a grating element, used to divide the detection light source into A plurality of horizontal stripe grating images or vertical stripe grating images; a moiré fringe projection screen, used to display the grating images emitted by the grating element; two image collectors, the image collectors are used to correspondingly collect the The grating image of the lens on one side; the controller is used to control the image collector to collect the image and obtain the corresponding Moiré interference fringe image to calculate the corresponding glasses parameters. The invention realizes the detection based on multi-point positions, and greatly improves the detection accuracy by calculating the average value, and accurately measures the center distance of the glasses and the center height of the lens, thereby obtaining accurate results and effectively solving the common problem in the current market. Existing problems.
Description
technical field [0001] The invention relates to the technical field of parameter detection, in particular to a device and method for detecting glasses parameters based on synthetic moiré fringe technology. Background technique [0002] Glasses are a kind of article that uses widely in people's life, and its quantity is big difficult to imagine. However, there is currently a lack of equipment on the market to detect parameters such as the center distance and center height of the glasses, resulting in the parameters of many glasses not meeting the standards, and the wearer is prone to discomfort; Among them, the glasses parameters usually include the power of the left and right glasses, the center distance, and the center height (lens) The distance from the lower edge of the frame), the degree of astigmatism, the axis degree of astigmatism, the degree of progressive film addition and other parameters. At present, the detection of spectacle lens parameters mainly uses a measur...
