The scheme can be implemented by a first frame positioning system, and the first frame positioning system can comprise an optical characteristic identifier, a processor and the like. The optical feature recognition device may be used to recognize optical features of each frame of image in the film, which may include features such as color, light transmittance, and reflectivity. The first frame positioning system can acquire the optical characteristics of each frame of image in the film through the optical characteristic identification device.
S120, determining a film first frame in each frame image according to the optical characteristics of each frame image.
It will be appreciated that there are test frames in the film for imaging testing of the film. Fig. 2 is a schematic color diagram of each frame of film in the film according to the embodiment of the present invention. As shown in fig. 2, the colors of the test frame film and the non-test frame film in the film are obviously different, and the optical characteristics of the color, the light transmittance and the like of each frame image are also different, so that the test frame can be identified according to the optical characteristics of each frame image, and then the first frame of the film is determined according to the test frame.
In one possible solution, the optical feature recognition device comprises a color recognition device; the optical features include color features;

and determining the first frame of the film in each frame image according to the color characteristics of each frame image.
The optical feature recognition device of the head frame positioning system may comprise 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, output calibration, single power supply and the like. The color recognition device may be based on the principle of three primary color sensing to achieve color recognition. Specifically, the color recognition device may include a red filter, a blue filter, and a green filter, and the color recognition device may acquire the red light intensity, the blue light intensity, and the green light intensity of each frame image, respectively, through the red filter, the blue filter, and the green filter. The color recognition device may determine a color characteristic of each frame image based on the red light intensity, the blue light intensity, and the green light intensity, wherein the color characteristic may be a color characterization value of each frame image. According to the color characteristics of each frame image, the first frame positioning system can determine a test frame in each frame image, and then determine the first frame of the film according to the test frame. For example, the first frame positioning system may determine whether the current frame image is a test frame according to whether the color representation value matched with the current frame image is within a preset threshold range.

The transmittance characteristics of the test frame and the non-test frame are obviously different, so that 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 may determine whether the current frame image is a test frame according to whether the light transmittance matched with the current frame image is within a preset light transmittance range. If the light transmittance of the current frame image is in the preset light transmittance range, determining the current frame image as a test frame, and determining the next frame of the test frame as a film initial frame.

In order to ensure the reliability of the first frame positioning of the film, the first frame positioning system can comprehensively judge the first frame of the film according to the color characteristics and the light transmittance characteristics of each frame of image. For example, if the color feature of the current frame image satisfies the color discrimination condition and the light transmittance feature satisfies the light transmittance discrimination condition, the current frame image is determined to be a test frame, and the next frame of the test frame is a film first frame.
On the basis of the above scheme, optionally, the determining the first frame of the film in each frame image according to the color feature and the light transmittance feature of each frame image includes:
