Embodiment
The present invention is further described in more detail below in conjunction with drawings and the specific embodiments.
The flow chart of the detected image treatment system function that Fig. 1 provides for the embodiment of the invention one, as shown in Figure 1, its concrete steps are as follows:
Step 101: set in advance detection number of times to each functional module of image processing system.
Step 102: select the test character, determine that character boundary and character are mixed into the position on the input picture.
The test character can be selected arbitrarily, and the number of character can be one, also can be more than two, and the size of each test character can be identical, also can be different, and each test character is positioned on the diverse location of input picture.
Step 103: will test character and be mixed on the input picture.
The form of input picture can be Bayer, YUV, RGB etc., and this step can adopt existing techniques in realizing.
Step 104: with the functional module of mixed image input picture treatment system, functional module is handled input picture according to the function of self.
Step 105: receive the output image after the functional module of image processing system is handled, identification character on output image.
Identification character can adopt existing optical character identification (OCR, Optical CharacterRecognition) algorithm.
Step 106: that selects in each character that will identify and the step 102 respectively tests character sequence relatively, judge whether all identical, if, execution in step 107; Otherwise, execution in step 109.
Step 107: whether the position of judging the character that identifies is all correct, if, execution in step 108; Otherwise, execution in step 109.
Difference in functionality according to functional module, the test character in the position on the output image may with different on input picture as: function is that image amplifies or dwindles, at this moment, need the position on input picture according to this function and test character earlier, calculate the position of test character on output image.
Step 108: this testing result of determining the current functional module of image processing system is normal, and testing result is shown to the user, goes to step 110.
Step 109: this testing result of determining the current functional module of image processing system is unusual, testing result is shown to the user, execution in step 110.
To be shown to the user to each testing result of each functional module, so that the user safeguards functional module.
Step 110: judge and whether detected number of times less than the default number of times that detects, if return step 102; Otherwise, execution in step 111.
Step 111: begin to detect next functional module.
Testing process to each functional module is identical.
In actual applications, image is continuous input picture treatment system normally, at this moment, character can be mixed into successively on each continuous input picture, then with the functional module of the continuous input picture treatment system of image of mixing.
For the same functional module of image processing system, detect the position that employed character, input picture, character boundary, character be mixed on the input picture can be identical at every turn, also can be different.
In the embodiment shown in fig. 1, be to behind the default detection of the same functional module cycle detection number of times, begin testing process again to next functional module; In actual applications, also all functions module can be carried out cycle detection as a detected object, that is: detected once successively to all functions module after, repeat this process again, reach the default number of times that detects until detecting number of times.
The flow chart of the detected image treatment system function that Fig. 2 provides for the embodiment of the invention two, as shown in Figure 2, its concrete steps are as follows:
Step 205: receive the output image after the functional module of image processing system is handled.
Step 206: determine the position of test character on output image, identification character on determined each position.
Step 207: judge whether on all positions, all to identify character, if, execution in step 208; Otherwise, execution in step 210.
Step 208: the test character sequence of selecting in all characters that will identify and the step 202 relatively, judge whether all identical, if, execution in step 209; Otherwise, execution in step 210.
Step 209: this testing result of determining the current functional module of image processing system is normal, and testing result is shown to the user, goes to step 211.
Step 210: this testing result of determining the current functional module of image processing system is unusual, testing result is shown to the user, execution in step 211.
Step 211: judge whether detected number of times equals the default number of times that detects, if, execution in step 212; Otherwise, return step 202.
Step 212: begin to detect next functional module.
