Online Marking refers to the computer network technology and image processing technology as the backing of a new scoring method. After the exam, high-speed Scanners On the candidate's answer sheet scanning to generate images File , Stored in the computer for grading teachers marking. 2009 college entrance examination, there are 28 provinces with the online marking method. Derived by the entrance open to, move around more and more of, examinations and even the schools themselves are beginning to widespread adoption of online marking of such high efficiency, low error in the scoring method. Canon DR-5010C high-speed scanners in this modern way of marking an important part of the job, and with excellent access to candidates and scoring the performance of teachers at home.
Earlier, Canon DR-5010C high-speed scanners used in college entrance examination on-line grading system, as this system becomes, Canon has also turned to the campus version of online marking system. Near the entrance has been subjected to harsh test of practice Canon DR-5010C, doing my part to stir up a new field of burden, a city in Hebei Education The successful application of the system case, the Canon authorized distributors and authorized service providers?? Beijing Hua Yi Rong Hui Technology Co., Ltd. will once again Canon DR-5010C and convenient service delivered to the Education of Heilongjiang province.
As the first of Daqing, Heilongjiang Province, the first focus of high school, provincial demonstration schools, Daqing secondary school graduates 25 years has trained more than 10,000, more than 9,000 people admitted to state colleges and universities of various types, test into schools such as Tsinghua University Beijing University nearly a hundred people. Fruitful results in teaching can not do without a solid foundation for the daily teaching and learning, the examination is to test the "grant" and "subject" of the most direct and rapid way, the shortcomings of traditional manual scoring methods, such as human and material consumption, scoring a long cycle assessment of error and so on, in the modern face of the online scoring systems, turned to the development of economic efficiency.
Canon DR-5010C is a widely used in many fields of ultra-small, high speed A3 Size Scanner, with a number of advantages for school grading. First, scan speed. Canon DR-5010C is as trouble-free, uninterrupted scan characteristics of various types of files, DR-5010C Canon introduced a new design of high-precision roller feed system to achieve active twist of paper, each with a message card can be very good to be separated to avoid the situation of heavy sheets of paper away.
The application of Canon's unique 3-line CMOS contact image sensor, 50 pages per minute for high-speed color scanning, using double-sided document scanning can be upgraded to 100 pages per minute, enough in a few hours "to resolve "Thousands of papers of the scanning.
In image transfer from the scanner to the computer, the process, DR-5010C built-in "JPEG compression" feature allows data to be compressed immediately and effectively reduce the transmission time. This saves from every detail "line" time, the online marking process will undoubtedly be more efficient.
Scan quality, DR-5010C Application of "advanced text enhancement technology" to ensure that all lead to illegible image files does not affect the marking of work factors. Whether writing or light-colored Pencil Graffiti, by detecting the position of writing paper, and emphasized to overcome such obstacles, they can get a clearer image text, which will help the image post-processing. Although the actual scoring process is rare, however, on this basis, if necessary, the operator can also get OCR image processing, to ensure the identification of aspects of the computer terminal display and better recognition results.
In addition, DR-5010C is designed in many human gardeners save their hard work many hard: large quantities of papers or answer sheets can be placed in the feeder once on, DR-5010C can be quickly and consistently The paper document is converted to Electronic Documents; straight into the path of the paper, skew detection, except their own custom color function is to ensure that every piece (instead of entrainment good few "false pretenses"), answer sheets are safe (not torn) into the scanner , and obtain high-resolution image fidelity. Very occasionally, if the scanning process due to transmission failures makes scanning stopped, DR-5010C intimate "rapid restoration of system function" is also allowed to re-place the respondents continue to scan. Because of failure incomplete document images are not transmitted to the computer, the manual and therefore save the trouble to delete incomplete information, such as information cards are very convenient presentation of this volume scan.
Education industry, though not a traditional industry, but also get to enhance scientific and technological development, renewed vigor. Canon DR-5010C, as successfully applied in-line scoring middle school in Daqing, in the use of such high frequency, high-speed scanner reveals the configuration of the entrance examination than only once a year better return on network access systems, in reducing test costs, the full use of existing resources, the effectiveness of teaching, while the Internet plays an important role in marking the high-speed scanners, specialized equipment can also be applied as a file Management , Student status management, the "multiple roles", to achieve a multifunctional. I am an expert from China Manufacturers, usually analyzes all kind of industries situation, such as hospital overbed table , fold up bed chair.
