First, special scanning equipment+online marking software
The scanning equipment used in the examination is both made in China and imported. The performance of imports is relatively stable, but the price is relatively expensive.
Using special scanning equipment is actually embedding the software for image recognition of information points on the answer sheet into the hardware scanning equipment, or binding the scanning recognition software with the hardware scanning equipment, which can be simply understood as "hard recognition".
This marking mode is generally suitable for large-scale exams such as joint exams and joint exams. Special scanning equipment is expensive and difficult to maintain, so it needs special personnel to maintain and organize inspection. At present, the entrance examination for senior high school entrance examination basically adopts this marking mode. ?
Second, general scanning equipment+online marking software?
Universal scanning equipment mainly refers to universal high-speed document scanner, which is available at home and abroad, but its performance and quality are better than those of foreign products.
Using general scanning equipment, the paper answer sheet image is actually scanned into an electronic image file by a high-speed document scanner, and then the information of the image is recognized by independent scanning recognition software, which can be simply understood as "soft recognition". ?
This marking mode is generally suitable for small-scale examinations such as daily tests and evaluations. Universal scanning equipment has low cost and simple operation, which is convenient for teachers to organize examinations independently. At present, the scanning equipment used in the easy 100 marking system is universal scanning equipment, which realizes automatic marking with points and is very suitable for daily examination marking!
