Embodiment
First embodiment provided by the invention is a kind of method of testing of status indicator lamp, and method flow comprises as shown in Figure 1:
Step 101: the port status that equipment under test is set is 10,000,000, determines that the state of port was set at 10,000,000 o'clock, the yellow corresponding rgb value of the expection of this port status pilot lamp correspondence.
Step 102: catch be set to 10,000,000 after, the image of equipment under test port status pilot lamp, and save as the graphic file of BMP (Bitmap, bitmap format) form.
Step 103: analyze by graphic file, in the image of catching, obtain the rgb value of port status pilot lamp place location of pixels to the BMP form preserved.
Step 104: compare according to the yellow corresponding rgb value of the rgb value of the port status pilot lamp place location of pixels that gets access to and expection and to draw test result.
Wherein in the step 101 only be state with the port of equipment under test to be set to 10,000,000 be that example describes, this port was set to 10,000,000 o'clock, corresponding status indicator lamp be yellow, if this port was set to 100,000,000 o'clock, then Dui Ying status indicator lamp is a green.Be not limited to the status indicator lamp of port, be equally applicable to indicator of the power supply status, other similar working station indicators such as integrated circuit board status indicator lamp.
Wherein can adopt following method to catch the image of equipment under test port status pilot lamp in the step 102:
Control is caught all images of equipment under test status indicator lamp place panel or is comprised the part panel image of status indicator lamp as image capture devices such as video camera, cameras.To catch the panel all images is example, as shown in Figure 2, all images zone that catch for image capture device in zone 1, zone 2 is the image-region of equipment under test status indicator lamp place panel.
When the image of catching is preserved, present embodiment only is that the graphic file with the BMP form describes, can also adopt the graphic file of forms such as GIF or JPEG equally, it is concrete picture format difference, during concrete enforcement to can be slightly different in the processing of the graphic file of different-format, but the image of the sort of form no matter all can be represented the color of each pixel by rgb value, and method is similar on the whole repeats no more herein.
In order in step 103, in the image of catching, to obtain the rgb value of port status pilot lamp place location of pixels, need measure the width W and the height H of equipment state pilot lamp place panel in advance, and measure the relative position of status indicator lamp, calculate the status indicator lamp relativity shift, as the distance on the status indicator lamp and the panel left side is that the distance of w and top is h, calculate w/W and h/H, obtain the relativity shift of Width and the relativity shift of short transverse.
In step 103, read the BMP graphic file according to binary format, from image, read the rgb value of each pixel from top to down by bitmap format, when the rgb value of the rgb value that reads and equipment under test coboundary color is identical is the coboundary, simultaneously the number of the pixel that reads is confirmed as the coboundary location of pixels, in like manner can draw left margin, right margin, the location of pixels of lower boundary.So just can determine the location of pixels of equipment under test border in image by the graphic file that reads the BMP form, determine status indicator lamp place location of pixels according to fixed relativity shift more afterwards, read rgb value according to the location of pixels of status indicator lamp in image.
Describe with concrete numerical value below, the width of measuring equipment under test is 20cm, highly be 4cm, A point in the status indicator lamp is 2cm apart from the distance on the equipment under test left side, the distance of top is 1cm, then the relativity shift of equipment under test Width is 2cm/20cm=0.1, and the relativity shift of equipment under test short transverse is 1cm/4cm=0.25.The image size is 800 (wide) *, 600 (height), top margin, bottom margin, left side distance, rightmargin all are 100 pixels, relativity shift=100+ (800-100-100) * 0.1=160 of the X coordinate of virtual condition pilot lamp A point respective pixel=left side distance+plant width * Width then, relativity shift=100+ (600-100-100) * 0.25=200 of the Y coordinate=top margin+device height * short transverse of A point respective pixel.
To how to read rgb value describe below according to location of pixels.Need to prove that at first the required figure place (biBitCount) of each pixel in the BMP file can be 1 (monochrome bitmap), 4 (16 color bitmaps), 8 (256 color bitmaps) or 24 (24 bitmaps) etc., when biBitCount=1,8 pixels account for 1 byte; When biBitCount=4,2 pixels account for 1 byte; When biBitCount=8,1 pixel accounts for 1 byte; When biBitCount=24, it is true color image that 1 pixel accounts for 3 byte images this moment.
In the graphic file of BMP form, be the rgb value of determining each pixel by data bitmap, determine the rgb value of each pixel of bitmap according to the record of data bitmap, record is to be from left to right in scan line in proper order, is from top to bottom between the scan line.From the file header of graphic file, obtain the reference position of data bitmap, determine the data bitmap of status indicator lamp respective pixel position correspondence again according to the reference position of data bitmap, data bitmap can be represented the rgb value difference in different ways according to the required figure place difference of each pixel in the BMP file, in 24 bitmaps, directly represent rgb value by data bitmap, and other less than color index value in 24 the use palette.With 16 color bitmaps is example, and a data bitmap is only represented color index value in the palette, obtains the RBG value by this index value in palette.The required figure place of each pixel is 4 in 16 color bitmaps, promptly 2 pixels account for 1 byte, adjacent pixels point used color index value in the palette on the right of first pixel of the 1st the byte representation bitmap lower left corner of data bitmap reference position and this pixel were gone together, last 1 first pixel of the byte representation bitmap upper right corner of data bitmap end position and this pixel color index value in the left side adjacent pixels point use palette of going together, other each pixel record is to be from left to right in scan line in proper order, is from top to bottom between the scan line.
Palette has been pointed out the component value of the red, green, blue of each color.Each index in the data bitmap group is all corresponding to a palette list item, and the list item number of palette is determined by biBitCount, works as biBitCount=1,, 2,16,256 list items is arranged at 4,8 o'clock respectively; When biBitCount=24, there is not the palette item.Also be, picture format is the simultaneous mode difference not, when being monochrome, 16 looks, read palette (also claiming color table) during 256 looks and obtain RGB information, when picture format is true color, directly read data bitmap and obtain RGB information,, do not have palette as when the time for true color, directly read data bitmap #1D5863 and correspond to corresponding BGR value this moment, 63 be the component of red color promptly also, 58 is the component of green color, and 1d is the component of blue color.
In actual applications, the rgb value that reads according to the location of pixels of status indicator lamp in image is a set, as comprise the rgb value of 100 pixels, in the step 104, the rgb value of these 100 pixels and the yellow corresponding rgb value of expection are compared, have the rgb value of 81 pixels identical, greater than preset threshold 80% with yellow corresponding rgb value, confirm that status indicator lamp is normal, otherwise confirm that status indicator lamp is undesired.Certainly can also when determining each border of equipment, remove noise using median filtering algorithm, make the border more clear through producing.
In practical operation, if the color of the color of device panel and status indicator lamp is approaching, then can use a test panel of specializing in the test use that differs far away with the status indicator lamp color to cover on the device panel, on test panel, draw and device panel boundary shape, the identical border of size, and make a call to a hole in the position at status indicator lamp place and get final product with the identical size of status indicator lamp with obvious lines.
