Description of the Invention: [Technical Field] The present invention relates to an optical measuring method and system, and more particularly to a method and system for optically measuring the flatness of a steel strip. [Prior Art] In the production process of steel coil products, the steel billet is rolled into a steel strip of the required product size after the rough rolling pass finish rolling process, and then coiled into a steel coil product, and then shipped. Further downstream processing is carried out to the downstream production line. In the process of extending the steel embryo into the steel strip and in the inspection of the finished products, the flatness is a measure of the surface geometry of the steel strip. Therefore, an online real-time flatness measuring instrument is provided for monitoring and instant feedback. The message is used to control the adjustment of the rough rolling pass and the finishing pass. However, in other subsequent processes for the production of coil products, such as annealing, coating, and the like, there is no online flatness measuring instrument to control the flatness of the rework of the formed steel strip. In the subsequent process, the flatness of the formed steel strip does not change much, and the on-line flatness measuring instrument is expensive, so in the economical consideration, there is no need to install such expensive online instant. Flat gauge. In the trend of higher and higher production quality requirements, the industry has already had the need for flatness testing of other steel strips in subsequent processes to produce more quality coil products, due to the existing online instant flatness.

To measure the surface flatness of the steel strip 100 within the measurement range, this method is not only practical The system with simple and high accuracy and the flatness of the optical measuring steel strip can greatly reduce the equipment introduction cost. Referring to Figures 4 and 5, a second comparison of the method for measuring the flatness of the steel strip of the present invention The preferred embodiment is similar to the first preferred embodiment in that the difference is obtained before the predetermined range measuring step 12 is performed - the reference distance is obtained in step 5, and the optical ranging device 3 measures the optical ranging After the distance data of the instrument 3 to the operation level = 21, the reference distance is obtained by subtracting the thickness of the to-be-measured tape _ from the distance data, and the thickness of the frame is the product specification. The actual thickness of the steel strip 100 is not to be measured. After the reference distance is obtained, the flatness is obtained in step 13, when the distance is calculated by the arithmetic processing device 4 for each distance in the distance array. After subtracting the reference distance respectively, an arithmetic data array is obtained, and then the operation data array is interpolated, and the distance between the steel strip (10) and the optical distance meter 3 is obtained. 'After the degree. —· After the reference distance, when the flatness is obtained, step: 13' may be first performed by the arithmetic processing device 4 to interpolate the measurement distance first, and then the average distance array is obtained, and then the distance array is Each of the values is reduced by: a 曰 £ 进而 进而 进而 进而 进而 进而 进而 $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ ^ ^ ^ ^ ^ ^ The obtained surface 8 201125653 flatness is taken as an absolute value and then 1 is less than four quarters of the thickness of the product specification to meet the flatness requirements of the current steel strip product. 3 With the working platform 21 5, it is not necessary to re-size the thickness of each time. It should be noted that when the distance of the optical range finder is not changed, the reference distance is required to be measured, and the new reference distance can be obtained by measuring the steel strip 1 according to the measurement.
