Detailed Description

The technical contents of the present invention will be described in detail with reference to the accompanying drawings and specific examples.

The embodiment of the invention can detect all the flicker recognition of the display screen icons, and the display screen is taken as an example for the following description.

< first embodiment >

In different embodiments of the present invention, the meter image is an image that captures the content displayed on the display screen of the dashboard in real time, and may be a test image during the production phase of the vehicle, or may be an actual display image during the running of the vehicle, which is not particularly limited in the present invention. In one embodiment of the invention, in the vehicle production stage, the display screens arranged in a row sequentially pass through the camera, and the camera is used for collecting images so as to implement the method for identifying the icon flicker of the display screens.

As shown in fig. 1 to 3, a first embodiment of the present invention discloses a method for identifying icon flicker of a display screen, including:

s1: and setting an icon expected value and an identification area of the display screen according to the prior information displayed by the display screen, and setting an area of interest.

The icon expected value and the identification area of the display screen are set according to the prior information displayed by the display screen, and the region of interest (Region of Interest, abbreviated as ROI) 10 is set.

Wherein the icon expected values include: color expected value, number of hops expected value. The two expected values are used for judging whether the color verification and the jump frequency verification pass or not respectively, and judging whether the icon is successfully verified or not according to whether the two verification passes or not.

Since the number of hops is equal to 2 times the flicker frequency, the number of hops verifies whether or not it passes the same as the flicker frequency.

It should be noted that, for different vehicle types, the preset regions of interest 10 are different; or the icons to be identified are different, and the preset regions of interest 10 are also different. That is, the region of interest 10 is determined by the model or icon position to be identified.

S2: and acquiring the images of the display screen according to the set identification area, and storing the acquired images into a series of pictures according to the acquisition sequence.

And acquiring the instrument images according to the set identification areas, and storing the acquired images into a series of pictures according to the acquisition sequence. As shown in fig. 2A and 2B, the meter image is acquired according to the set identification area, and the acquired image is saved as a series of pictures in the acquisition order, and the names of the pictures are picture1, picture2 and picture3 … …. Each frame of picture comprises at least the complete region of interest 10.

When the instrument image is acquired through the camera, the RGB camera is preferably used, and the color information is accurately acquired; meanwhile, photographing is completed in a camera bellows environment, and reflected light interference can be effectively reduced. As shown in fig. 2A and 2B, the image acquisition modes include, but are not limited to, electronic screen capturing and photographing modes, and are automatically completed by the device, so that the image acquisition accuracy is improved.

The requirements on the frequency and the acquisition time of image acquisition are as follows:

if the expected value of the flicker frequency of the identification icon is f (expected flicker frequency), the expected flicker frequency of the icon is not less than 2 times the number of frames per second (fps) of image acquisition (i.e., the image acquisition frequency is 2 f), which is operated to ensure that the icon is subjected to 2 hops within one period, and identification is performed based on the detected hops.

For N consecutive cycles of image acquisition (i.e. the inverse of the expected flicker frequency), preferably 10 consecutive cycles. The display screen is stationary relative to the camera during these N periods to ensure that the position of each icon in each frame of pictures is fixed throughout the series of pictures. Wherein N is a positive integer.

After the image is acquired by using a photographing mode, if the image needs to be calibrated, the following method can be used: the first icon 1 and the second icon 2 which are preset are triggered to flash, as shown in fig. 2A, the positions of the two icons (the first icon 1 and the second icon 2) in the same frame of picture are obtained, and the proportional relation between the picture and the electronic design is obtained by comparing the difference of the positions of the two icons in the same frame of picture with the difference of the positions of the two icons (the known value in advance) displayed in the electronic design. And then the position of the icon 3 to be identified in the region of interest can be calculated through the proportional relation, the reference coordinates in one frame of picture, the positions of the first icon 1, the second icon 2 and the icon 3 to be identified in the electronic design drawing, which are known in advance, as shown by the icon 3 to be identified in fig. 2B.

The electronic design drawing is a known display screen original design engineering drawing. The proportion of the pictures shot by the camera is the same as that of the electronic design drawing. But picture calibration is not required if the image acquisition mode of electronic screen capturing is used.

S3: and detecting the outline display state of the icon 3 to be identified in the region of interest in a series of pictures in N periods.

Since the position of the icon 3 to be recognized has been calculated in step S2, the outline display state of the image at that position in each frame of picture is detected.

The outline display state of the detected icon 3 to be recognized is shown in fig. 3. The specific method for detecting the outline display state comprises the following steps: subtracting two adjacent frames of pictures, and taking absolute values of the results, namely |Picture2-Picture1|, to obtain the distribution of 0 and 1. Whether the profile display state is changed is judged by the distribution of 0 and 1.

As is well known, in the case of camera shooting, the subtraction of images generates a lot of residues, and the state of the contour subtraction of 0 cannot be achieved. Therefore, the invention uses corrosion to realize the filtration of interference, so that the picture pixel data does not have interference factors, therefore, the pixel data can only be all 0 or all 1, and all 0 means all off and all 1 means all on; the filtering effect of corrosion is shown in fig. 4 and 5. In addition to corrosion, the filtering may be performed by other methods of image morphology, which are known in the art and are not described herein.

And respectively corroding two adjacent frames of pictures, binarizing the pixel data of the two adjacent frames of pictures, subtracting the pixel data corresponding to the two frames of pictures after binarization, and storing the absolute values obtained by subtracting the pixel data corresponding to the two frames of pictures into a list.

Wherein the absolute values in the list are all 0, which indicates that the outline display state of the icon 3 to be identified in the interested area of the two adjacent frames of pictures is unchanged (i.e. the state of the pixel in the two frames of pictures is not changed in a bright and dark state); the absolute values in the list are all 1, which indicates that the outline display state of the icon 3 to be identified in the region of interest of the two adjacent frames of pictures changes (i.e. the pixel in the two frames of pictures changes in state of being on or off, or is on or off).

And then determining the change of the outline display state of the icon 3 to be identified according to the distribution of 0 and 1 in the list (namely, the distribution of 0 and 1 in the list). And in N periods, if the absolute value in the list of the icons 3 to be identified is continuously 0 in all the frame pictures, namely 1 does not appear in the N periods, the outline display state of the icons 3 to be identified is continuously unchanged, namely the interested area does not flicker, and the step S4 is performed. If the absolute value in the list of the icons 3 to be identified in all the frame pictures is hopped by 0 and 1 (i.e. not all 0 and not all 1), the outline display state is changed, i.e. the interested area flickers, and the step S6 is entered.

Here, there are two cases when the outline display state of the icon 3 to be recognized in the region of interest is continuously unchanged (i.e., the icon 3 does not blink):

(1) Icon 3 in the region of interest continues to light up (no extinction occurs during N cycles)

(2) The icon 3 in the region of interest remains unlit (no lighting occurs during N cycles)

Further determination is required for both cases, i.e. in step S4.

Because only one condition of flickering occurs on the icon 3 to be identified in the region of interest, namely, continuous jump of on and off is performed, and no continuous bright or unlit condition exists, step S4 is not needed, and only the frequency of jump is needed to be further judged, namely, step S6.

S4: and under the condition that the outline display state of the icon 3 to be identified is continuously unchanged, judging whether the icon 3 to be identified in the interested area of the picture is displayed under the condition that the interested area does not flicker according to whether the icon 3 to be identified in the interested area of each frame of picture is displayed.

If the icon 3 to be identified in the region of interest has a contour, that is, the icon 3 to be identified in the region of interest has a display, step S5 is entered; if the icon 3 to be identified in the region of interest does not display an outline, that is, the icon 3 to be identified in the region of interest is not displayed, it is further determined whether the icon is not displayed to conform to the expected color value, and the step S9 is proceeded.

Optionally, whether the icon 3 to be identified has a display contour is judged by the contour pixel RGB value, if the contour pixel RGB value is greater than 0, the icon 3 to be identified is indicated to have the display contour; if the contour pixel RGB value is equal to 0, it indicates that the icon 3 to be identified has no contour displayed.

S5: and (3) carrying out color recognition on the icon 3 to be recognized in the region of interest in each frame of picture, judging whether the icon accords with the expected color value, and entering step S9.

If the icon 3 to be identified in the region of interest in each frame of picture is subjected to color identification, judging that the icon meets the expected color value, and passing the color verification; if not, the color verification is not passed.

Optionally, whether the color of the icon 3 to be identified meets the expected color value is determined by the RGB value of each contour pixel of the icon 3 to be identified. Wherein the expected value of the color is a set value, for example: the tire pressure icon is yellow, the high beam icon is blue, and the low beam icon is green, and the color setting is defined by each manufacturer, so the invention is not limited.

S6: and judging whether the jump is uniform.

The jump is judged to be uniform based on the distribution of 0 and 1 in the list, where the duty ratio (duty ratio) of 0 or 1 is 40 to 60% (preferably 50%). If the jump is uniform, the step S7 is carried out; if the hopping is not uniform, the hopping number is not in accordance with the expected value, and the process proceeds to step S9.

S7: and judging whether the hopping times meet the expected value of the hopping times according to the hopping times in one period, and entering step S8.

If the hopping frequency in one period is equal to 2f, the hopping frequency is consistent with the expected value of the hopping frequency; if the hopping number in one period is not equal to 2f, the hopping number is not in accordance with the expected value of the hopping number.

If the hopping times meet the expected value of the hopping times, the hopping times pass verification, namely the flicker frequency passes verification; if the hopping frequency does not accord with the expected value of the hopping frequency, the hopping frequency is verified to be not passed, namely the flicker frequency is verified to be not passed, and the current flicker frequency is recorded.

S8: and identifying the color of the jump of the icon 3 to be identified in the region of interest, judging whether the color meets the expected value of the color, and entering step S9.

Optionally, whether the color meets the color expected value is judged by the contour pixel RGB value of the icon 3 to be identified.

If the color accords with the color expected value, the color verification is passed; if the color does not meet the expected value of the color, the color verification is not passed, and the current color is recorded.

S9: and (3) summarizing the jump times and the color results judged in the steps S4-S8 according with the icon expected values, and outputting a recognition result report.

If the color verification and the flicker frequency verification are passed, the icon is indicated to be displayed normally, namely the icon verification is successful; if any one or all of the color verification or the jump number verification is not passed, the icon is indicated to be displayed abnormally, namely the icon verification fails.

When the icon is successfully verified, the output form of the result report is as follows: color, flicker frequency verification was successful. When the icon verification fails, the result report has the following three output forms:

1. if the color verification is not passed and the flicker frequency verification is passed, the output flicker frequency accords with the expected value. The color does not accord with the expected value, and the current color is output;

2. and if the color verification is passed and the flicker frequency verification is not passed, outputting that the flicker frequency does not accord with the expected value, and outputting the current flicker frequency. The color meets the expected value;

3. if the color verification is not passed and the flicker frequency verification is not passed, outputting that the flicker frequency does not accord with the expected value, and outputting the current flicker frequency. The color does not conform to the expected value and the current color is output.

It should be noted that, in this embodiment, a display screen displaying instrument information on a vehicle is described as an example, which is only for explaining the method for identifying the flicker of the display screen, and the method for identifying the flicker of the display screen is not limited to be applied to the detection of the display screen of the vehicle, and the method for identifying the flicker of the display screen can be applied to the detection and identification of various display screens, and has a wide application prospect.

Optionally, cluster extraction is performed according to the colors of the icons, and at least one group of colors is extracted;

preferably, two sets of primary colors, namely a first primary color and a second primary color, are extracted. In the judging process, two groups of main colors are respectively judged.

If the color jumps, entering step S4; if no color jump occurs, the process proceeds to step S6.

S4: and judging whether the jump is uniform.

To improve the accuracy of the detection, it can be detected whether the occurrence of the jump is sufficiently uniform to prove whether it corresponds to a flicker with a duty cycle of 50%.

If the jump is uniform, entering step S5; if the hopping is not uniform, the hopping is not in accordance with the expected value of the hopping number, and the step S7 is performed.

S5: and judging whether the hopping times meet the expected value of the hopping times according to the hopping times in one period, and entering step S7.

S6: and comparing the color of the icon with the background color, and judging whether the icon is normally bright.

Wherein the background color is fixed to gray black.

If the icon color is the same as the background color, the icon is not normally bright, whether the situation accords with the color expected value is judged, and the step S8 is carried out; if the icon color does not match the background color, the icon is normally bright, and the process proceeds to step S7.

Optionally, whether the color meets the color expected value is judged through the RGB value of the icon.

S7: and judging whether the icon color accords with the color expected value or not, and proceeding to step S8.
