[0027] Embodiment one

[0028] Figure 1 A flowchart of a film first frame determination method is provided for the embodiment one of the present application. The present embodiment can be applicable to a film first frame positioning scenario. The method can be executed by a film first frame determination device. The device can be realized in the form of hardware and / or software. The device can be configured in an electronic device. As shown in the figure, the method comprises the following steps. Figure 1

[0029] S110, sequentially acquiring optical features of each frame image in the film by an optical feature recognition device.

[0030] ​The scheme can be executed by a first frame positioning system, which can include an optical feature recognizer, a processor, and the like. The optical feature recognizer can be used to recognize optical features of each frame of images in the film, which can include color, transmittance, reflectivity, and the like. Through the optical feature recognizer, the first frame positioning system can obtain the optical features of each frame of images in the film.

[0031] In S120, the first frame of the film is determined from the optical features of each frame of images.

[0032] It can be understood that the test frame exists in the film for imaging test of the film. Figure 2 is a color diagram of each frame of film in the film according to an embodiment of the present application. As shown in Figure 2 The color of the test frame film is obviously different from that of the non-test frame film in the film, and each frame of images also has differences in optical features such as color and transmittance. Therefore, the test frame can be recognized according to the optical features of each frame of images, and the first frame of the film can be determined according to the test frame.

[0033] In a feasible scheme, the optical feature recognizer includes a color recognizer; and the optical features include color features.

[0034] The optical features of each frame of images in the film are sequentially obtained by the optical feature recognizer, including:

[0035] The color features of each frame of images in the film are sequentially obtained by the color recognizer.

[0036] The first frame of the film is determined from the color features of each frame of images.

[0037] The first frame of the film is determined from the color features of each frame of images.

[0038] The optical feature recognition device of the first frame positioning system can include a color recognition device, such as a color recognition sensor TCS230. The color recognition device can have the characteristics of high resolution, programmable color selection and output scaling, and single power supply. The color recognition device can be based on the principle of three primary color sensing to realize color recognition. Specifically, the color recognition device can include a red filter, a blue filter, and a green filter. The color recognition device can obtain the red light intensity, the blue light intensity, and the green light intensity of each frame of image through the red filter, the blue filter, and the green filter, respectively. According to the red light intensity, the blue light intensity, and the green light intensity, the color recognition device can determine the color feature of each frame of image, wherein the color feature can be a color representation value of each frame of image. According to the color feature of each frame of image, the first frame positioning system can determine a test frame in each frame of image, and then determine the first frame of film according to the test frame. For example, the first frame positioning system can determine whether the current frame of image is a test frame according to whether the color representation value matched by the current frame of image is within a preset threshold range. If the color representation value matched by the current frame of image is within the preset threshold range, the current frame of image is determined to be a test frame, and the next frame of the test frame is the first frame of film.

[0039] In another possible implementation, the optical feature recognition device includes a light transmittance recognition device, and the optical feature includes a light transmittance feature.

[0040] The sequentially obtaining, by the optical feature recognition device, the optical feature of each frame of image in the film includes:

[0041] The sequentially obtaining, by the light transmittance recognition device, the light transmittance feature of each frame of image in the film includes:

[0042] The determining, according to the optical feature of each frame of image, the first frame of film in each frame of image includes:

[0043] The determining, according to the light transmittance feature of each frame of image, the first frame of film in each frame of image.

[0044] The first frame positioning system can also distinguish the transmittance characteristics of each frame of image, position the test frame, and further determine the first frame of the film. The optical characteristic recognition device can include a transmittance recognition device, such as a 5mm slot optical fiber sensor PUE-4005 of BOJKE. Through the transmittance recognition device, the first frame positioning system can obtain the transmittance characteristics of each frame of image, where the transmittance characteristics can be the matching transmittance of each frame of image, or the light intensity value transmitted by each frame of image under the same incident light intensity. The transmittance characteristics of the test frame and the non-test frame are obviously different, and therefore, the first frame positioning system can position the test frame according to the transmittance characteristics, and further determine the position of the first frame of the film. For example, the first frame positioning system can determine whether the current frame of image is the test frame according to whether the matching transmittance of the current frame of image is within a preset transmittance range. If the matching transmittance of the current frame of image is within the preset transmittance range, the current frame of image is determined as the test frame, and the next frame of the test frame is the first frame of the film.

[0045] In a preferred scheme, the determining the first frame of the film in each frame of image according to the optical characteristics of each frame of image comprises:

[0046] The first frame of the film is determined in each frame of image according to the color characteristics and the transmittance characteristics of each frame of image.

[0047] In order to ensure the reliability of the positioning of the first frame of the film, the first frame positioning system can comprehensively determine the first frame of the film according to the color characteristics and the transmittance characteristics of each frame of image. For example, if the color characteristics of the current frame of image satisfy the color discrimination condition, and the transmittance characteristics satisfy the transmittance discrimination condition, the current frame of image is determined as the test frame, and the next frame of the test frame is the first frame of the film.

[0048] On the basis of the above scheme, optionally, the determining the first frame of the film in each frame of image according to the color characteristics and the transmittance characteristics of each frame of image comprises:

[0049] The first determination result of the first frame of the film is determined according to the color characteristics of each frame of image;

[0050] The second determination result of the first frame of the film is determined according to the transmittance characteristics of each frame of image;

[0051] The first frame of the film is determined according to the first determination result and the second determination result.

[0052] The first frame positioning system can also respectively determine the first frame of the film in each frame of image according to the color characteristics and the transmittance characteristics, and respectively obtain the first determination result and the second determination result. If the first determination result is consistent with the second determination result, the image frame indicated by the first determination result and the second determination result is determined as the first frame of the film.

[0053] The technical scheme acquires optical characteristics of each frame of images in the film through optical characteristic recognition devices in the first frame positioning system; and determines the first frame of the film in each frame of images according to the optical characteristics of each frame of images. The scheme solves the problem of large limitation of mechanical positioning of the first frame of the film, and can recognize the first frame of the film through image processing, thereby improving the positioning accuracy of the first frame of the film and ensuring the reliability of data resource acquisition.

Specifically, the color characteristic comparison result can be a color characteristic difference, such as a color representation value difference, between adjacent two frames of images.

[0059] S230, if it is determined according to the color characteristic comparison result that the colors of adjacent two frames of images are different, then the adjacent two frames of images are taken as a first candidate frame of image and a second candidate frame of image respectively.

[0060] According to the color characteristic comparison result, the first frame positioning system can determine whether the colors of adjacent two frames of images are the same. Specifically, the first frame positioning system can determine whether the colors of adjacent two frames of images are the same according to whether the color representation value difference is within a preset difference range. If the color representation value difference is within the preset difference range, it is determined that the colors of adjacent two frames of images are the same. If the color representation value difference is not within the preset difference range, it is determined that the colors of adjacent two frames of images are different.

[0061] If the colors of adjacent two frames of images are different, it means that one of the two frames is a target frame, i.e. a test frame. The first frame positioning system can take the adjacent two frames of images as a first candidate frame of image and a second candidate frame of image respectively, and determine the color characteristic comparison result of the first candidate frame of image and the adjacent frame of image of the first candidate frame of image, and the color characteristic comparison result of the second candidate frame of image and the adjacent frame of image of the second candidate frame of image.

[0062] ​S240, determining a color judgment result of the first candidate frame image according to the color feature comparison result of the first candidate frame image and the adjacent frame image of the first candidate frame image, and determining a color judgment result of the second candidate frame image according to the color feature comparison result of the second candidate frame image and the adjacent frame image of the second candidate frame image.

[0063] The color judgment result includes color same and color different.

[0064] S250, determining a target frame according to the color judgment result of the first candidate frame image and the color judgment result of the second candidate frame image.

[0065] If it is determined that the color of the first candidate frame image is the same as that of the adjacent frame image of the first candidate frame image according to the color feature comparison result of the first candidate frame image and the adjacent frame image of the first candidate frame image, and it is determined that the color of the second candidate frame image is different from that of the adjacent frame image of the second candidate frame image according to the color feature comparison result of the second candidate frame image and the adjacent frame image of the second candidate frame image, the second candidate frame image can be determined as the target frame.

[0066] If it is determined that the color of the first candidate frame image is different from that of the adjacent frame image of the first candidate frame image according to the color feature comparison result of the first candidate frame image and the adjacent frame image of the first candidate frame image, and it is determined that the color of the second candidate frame image is the same as that of the adjacent frame image of the second candidate frame image according to the color feature comparison result of the second candidate frame image and the adjacent frame image of the second candidate frame image, the first candidate frame image can be determined as the target frame.

[0067] S260, determining a next frame of the target frame as a film first frame.

[0068] The technical solution obtains the color features of each frame image in the film through a color recognition device in sequence, and determines the film first frame in each frame image according to the color features of each frame image. The solution solves the problem of large limitation of mechanical positioning of the film first frame, and can recognize the film first frame through image processing, thereby improving the positioning accuracy of the film first frame and ensuring the reliability of data resource acquisition.

[0072] ​S320, compare the light transmittance features of the two adjacent frames of images in sequence to determine a light transmittance feature comparison result.

Specifically, the light transmittance feature comparison result can be the difference of the light transmittance features of the two adjacent frames of images, for example, the difference of the light transmittance.

[0074] S330, if it is determined according to the light transmittance feature comparison result that the light transmittance of the two adjacent frames of images is different, then the two adjacent frames of images are respectively taken as the first candidate frame of image and the second candidate frame of image.

[0075] According to the light transmittance feature comparison result, the first frame positioning system can determine whether the light transmittance of the two adjacent frames of images is the same. Specifically, the first frame positioning system can determine whether the light transmittance of the two adjacent frames of images is the same according to whether the difference of the light transmittance characteristic values is within the preset difference range. If the difference of the light transmittance characteristic values is within the preset difference range, it is determined that the light transmittance of the two adjacent frames of images is the same. If the difference of the light transmittance characteristic values is not within the preset difference range, it is determined that the light transmittance of the two adjacent frames of images is different.

[0076] If the light transmittance of the two adjacent frames of images is different, it means that one of the two frames is the target frame, i.e. the test frame.
