Art test paper computer auxiliary scoring method

Technical field

The invention belongs to the Computer Applied Technology field, relate to a kind of method of Computer Processing graph image, particularly a kind of method to go over files of realizing art test paper with area of computer aided.

Background technology

At present, adopt for reading and making comments of art examination paper always a kind of the most original, the simplest complete manual mode of going over examination papers.Not only efficient is not high, and the fairness of going over examination papers also can not get good embodiment, the possibility of makeing mistakes in addition.And in the process of going over examination papers, require great amount of manpower to carry a large amount of papers.The difficulty of the security work of paper is also very big.

Summary of the invention

The technical problem to be solved in the present invention provides a kind of at Arts plane fine arts test paper computer auxiliary scoring method, this method has changed the mode of going over examination papers of traditional Arts paper, overcome a lot of drawbacks of traditional method to go over files, fair, just, efficient more.The principal character of this method is to change the way of directly original paper being read and made comments that extensively adopts at present, is digital picture then adopt the paper image acquisition, utilizes computer network to pass through following algorithm and realizes computer auxiliary scoring.

Technical scheme of the present invention may further comprise the steps:

One, sets up system manager's account and taster's account on computers, determine it to have different authorities according to the character of account;

Two, paper is generated in the Computer Database that uploads to behind the JPG file as server by digital collection equipment;

Three, participating in the number of checking of evaluation and test should be for more than 2 people, below represents that with N N is the natural number more than or equal to 2;

Four, each taster begins to go over examination papers, and method to go over files is: if single ballot just can produce the paper that passes through of specified quantity, the end of then going over examination papers.Otherwise carry out single ballot again, produce the paper that passes through of requirement.This method at most only need be carried out twice ballot, just can produce the paper that passes through that satisfies the specified quantity requirement.Idiographic flow is as follows:

The 1st step: first poll, N taster will vote X separately through and open paper in all papers.After each taster's first poll, number of votes obtained is that the paper quantity of i is A (i); Number of votes obtained is M (Z) more than or equal to the paper total quantity of Z ticket, promptly $M\left(Z\right)=\underset{i=z}{\overset{N}{\mathrm{\Σ}}}A\left(i\right);$ If there is Z, wherein Z is the integer more than or equal to 1, and M (Z) then directly enters step 5 when equaling X, bears results, and evaluation and test finishes; Otherwise need second poll, entered for the 2nd step;

The 2nd step: calculating need be carried out the quantity of second poll.

Calculate M (Z) successively, Z begins to successively decrease from N, finds first to satisfy the Z value of M (Z)＞X.The paper quantity that then needs to participate in second poll is A (Z);

As from the foregoing, producing the paper of disputing on is that number of votes obtained is A (Z) the paper of Z in first poll; Each taster need open in the paper additional ballot at this A (Z) and produces Y and open by paper in second poll, Y=X-M (Z+1) wherein, and all the other papers among the A (Z) are eliminated.Be that number of votes obtained is that the paper of Z need carry out second poll in the first poll.

The 3rd step: system will need A (Z) paper of second poll to distribute to each taster's number of the account by the following method, and method is:

(1) from A (Z) paper, gets a paper;

(2) from N account number, find out and in first poll, do not throw N-Z the account number that this paper passes through;

(3) from this N-Z account number, find out second poll and be assigned with the minimum account number of paper number;

(4) this paper is distributed to account;

(5) get back to (1), distribute next paper, open paper up to distributing A (Z);

The 4th step: carry out second poll.If the paper quantity that each number of the account is distributed is P (N), each number of the account need be chosen again

Open by paper (one 4 house 5 integers of going into behind the radix point), evaluation and test finishes.

What five, produce at last passes through the paper number within the scope of X ± N, satisfies the demands substantially.

Effect of the present invention and benefit are: simplified the work of going over examination papers of Arts paper, realized the mutual isolation between the taster, spatially eliminated between the taster communication with exchange, improved the fairness of going over examination papers.The algorithm of employing science guarantees that the end product of each paper all combines each taster's suggestion to greatest extent, has guaranteed the fairness of going over examination papers, and fairness has been simplified the organization work of the process of going over examination papers.

Description of drawings

Accompanying drawing 1 is to calculate the method synoptic diagram that passes through paper for the second time.

Accompanying drawing 2 is paper distribution method synoptic diagram of second poll.

Embodiment

Be described in detail specific embodiments of the invention below in conjunction with technical scheme and accompanying drawing.

Embodiment:

There is multiple type of account in the computer auxiliary scoring system that the present invention realizes, comprises the system manager, the teacher that gos over examination papers, paper typing personnel.Main workflow comprises the paper typing, paper stepping (grouping), several steps such as paper marking.Idiographic flow is exemplified below:

A, picture typing: have 2000 examinees to participate in my school Arts professional examination, upload in the SQL database after 2000 papers are gathered into jpg format-pattern file by digital camera, and finished the initial work of paper;

B, require ballot select 400 (be X=400, condition such as this numeral is according to enrollment admission number, the number of people who enter themselves for the examination with go over examination papers before determine) paper is qualified paper, the work of going over examination papers is finished by 3 (being N=3) taster's first, second, third.The workflow of going over examination papers is as follows:

Every taster of B1 independently gos over examination papers, and is the paper ballot, and default everyone need submit to X=400 to open paper;

After B2 submitted to for the first time, system was as follows through statistics: (with reference to the accompanying drawings 1)

3 ticket papers, A (3)=100, M (3)=100 is so directly pass through less than X;

2 ticket papers, A (2)=200, M (2)=A (1)+A (2)=300 is less than X, so directly pass through;

1 ticket paper, A (1)=300, M (1)=A (3)+A (2)+A (1)=100+200+300=600,

As seen there is not Z to satisfy M (Z)=X=400.

M (3)=100; M (2)=300; M (1)=600; First Z that satisfies M (Z)＞X is 1.Promptly need from A (Z)=A (1)=300 paper, to select Y=X-M (Z+1)=400-M (2)=400-300=100 and open paper for passing through paper.

B3 is that every taster distributes the paper step: (with reference to the accompanying drawings 2)

Extract first paper from get 1 ticket paper A (1)=300 out, second has been thrown ticket, so do not distribute to second, first third does not throw, because first, first third is not all distributed paper, so according to distributing to first in proper order earlier; Second paper of extraction from get 1 ticket paper A (1)=300, or second again thrown ticket, and first third does not throw, the paper number that elder generation's judgement first third is assigned with, and at this moment first has one, and third does not have, and then first is than more than third, so second paper distributes to third; By that analogy, 3 people have obtained the average relatively own 1 ticket paper of not voting for the first time of quantity.

Suppose that last first assigned to P (1)=90, second and assigned to P (2)=110, third and assigned to P (3)=100.

The B4 first needs to throw again $P\left(1\right)\×\frac{Y}{A\left(1\right)}=90\×\frac{100}{300}=30$ Ticket, second need to throw again $P\left(2\right)\×\frac{Y}{A\left(1\right)}=110\×\frac{100}{300}=37$ Ticket, third needs to throw again $P\left(3\right)\×\frac{Y}{A\left(1\right)}=100\×\frac{100}{300}=33$ Ticket,

P(1)+P(2)+P(3)＝Y＝100。

For the second time first, second, third is respectively them not have the paper of ballot to throw ticket according to the votes of redistributing for the first time, has promptly produced the paper that Y=100 opens 2 tickets again, has reached the X=400 opening and closing lattice paper of stipulating.

C, end ballot are preceding 400 papers marking ordering.

This method proof in test practice has increased substantially the art test paper efficient of going over examination papers really, has embodied fairness to greatest extent, has reduced working strength.
