All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without inventive step, are within the scope of the present invention.
The embodiment of the invention provides an electronic homework correcting system, which comprises a teacher end, a student end and a background server, wherein the teacher end is connected with the student end; the teacher end and the student end can be realized by intelligent terminals such as a smart phone, a tablet computer or a personal computer; the background server can be realized by high-performance computers such as workstations, mini-computers and the like or clusters thereof. The students can use the student end to complete the homework arranged by the teacher in an electronic mode, and the completed homework is uploaded to the background server to be stored. The teacher can use the teacher end to open the electronized homework completed by the students from the background server, and use the teacher end to carry out correction and upload the corrected homework to the background server. Then, the students can receive the homework after correction through the student end and check the correction content of the teacher.
Fig. 1 is a schematic flow chart of an implementation of an online correction job method according to an embodiment of the present invention, and as shown in fig. 1, the method includes:
step 101, displaying the content of an electronic operation in a correction area by using a first color system, and taking the electronic operation as a first image layer;
specifically, the teacher end can use CANVAS drawing control to realize a correction area, when the teacher needs to correct the operation, the teacher end can log in a background server first, open a WEB page of 'no correction operation', and select the operation to be corrected from the WEB page, wherein the operation can be stored as an electronic image or an electronic text;
the teacher end displays the operation in a correction area realized by the CANVAS drawing control in a first color system, and the method specifically comprises the following steps:
mapping the colors corresponding to all pixels of the electronic image into colors in a first color system, for example, the first color system is a black and gray color system, and converting the color image into a gray image if the electronic operation corresponds to the electronic image being a color image; or the electronic text is displayed in the first color and then converted into an electronic image, for example, if the first color system is a black and gray system, the characters of the electronic text are displayed in black, and the text format is converted into the image format; certainly, if the corresponding electronic image of the electronic operation is the image of the first color system, the conversion is not needed;
the teacher end displays the first color system image meeting the condition in the correction area, and uses the first color system image as a first image layer, particularly, the first image layer is a background image layer;
here, the format of the image may be saved as a format such as PNG or JPG;
102, providing an ink tool for editing the correcting area, wherein the color of the ink is a second color, and the second color does not belong to the first color system;
specifically, the teacher end may provide an ink tool for editing the correction area by using the CANVAS drawing control, where the color of the ink tool is a second color, and the second color may be preset in the teacher end, for example, set to red, or may be selected by a user (i.e., a teacher); whether preset or selected by a user, in order to be distinguished from the contents of the electronic job, the second color does not need to belong to the first color system, for example, if the first color system is a black and gray color system, the second color cannot be any one of black, gray or black and gray color system, and the second color may be red, blue, and the like; therefore, when the second color can be selected by the user, it is necessary to mask the color options in the first color system, for example, the first color system is a black and gray color system, and all the colors in the black and gray color system are masked in the ink tool color options;
103, recording correction ink input by a user through an ink tool, and taking the ink as a second layer;
specifically, the mode of receiving the user input by the correcting area at the teacher end may be mouse input, handwriting pen input or mobile phone sliding touch screen input, that is, the teacher end records a motion track generated by moving a mouse, a handwriting pen or a finger of the user, uses the motion track as correcting ink of the teacher correcting electronic job, displays the motion track in the correcting area with the second color, that is, finishes recording the correcting ink input by the user through an ink tool, and uses the ink as a second layer;
further, the recording of the motion trajectory generated by the user by moving the mouse, the stylus pen, or the finger specifically includes:
the teacher continuously captures mouse, handwriting pen or finger movement events according to a preset frequency; here, the preset frequency may be preset in the system according to the level of the precision requirement for drawing lines, for example, when the precision requirement is not high, coordinate capture is performed at a frequency of capturing 10 times per second, and when the precision requirement is high, coordinate capture is performed at 30 times per second;
recording the coordinates of each mobile event corresponding to the correction area;
connecting the coordinates one by one through straight line segments according to the sequence to generate the motion trail of the mouse, the handwriting pen or the finger;
for example, when a teacher uses a mouse to input ink marks, the teacher can continuously capture coordinates of the mouse on a drawing board of a correction area through a mouse moving event of JS, and then continuously store the captured coordinates into a memory array according to the sequence; simultaneously, when the mouse on the drawing board of the correction area moves to a new coordinate point, a small line segment is drawn on the drawing board of the correction area, the starting point of the line segment is the coordinate of the point captured last time, the end point is the coordinate of the point captured at present, and then the line segment is drawn continuously to form an approximate continuous curve;
in this way, how the user moves the mouse, the handwriting pen or the finger, what curve is generated in the correction area, so that the user can realize correction marks such as drawing lines, drawing x' and drawing check marks by moving the mouse, the handwriting pen or the finger without memorizing various complicated editing buttons, and can directly write the comment on the electronic operation in a handwriting mode;
step 104, after receiving the confirmation information of the user, placing the second layer on the first layer, and combining the second layer and the first layer into a pair of images for storage;
specifically, after completing the correction operation, the teacher may input confirmation information to the teacher end by selecting a "confirm" or "save" button or other manners for confirming that the correction is completed, and after the teacher end receives the confirmation information of the user, the teacher end places the second layer on the first layer through the CANVAS drawing control and combines the second layer into an image for saving; here, the merged image may be saved in a format such as PNG or JPG.
Further, after step 104, the method may further include:
and uploading the combined image to a background server by the teacher end, and preferably, converting the teacher end into a BASE64 character string form so as to facilitate network transmission.
