It can monitor in real time 24 hours a day, and can see farther and more clearly than the human eye. At the same time, it can also provide image support for the smart scenes that people need. In these smart scenes, by identifying and analyzing the images obtained by the camera, analysis results that match the scene are made, and the occurrence of emergencies is prevented or stopped in a timely and effective manner.

[0033] The present application example can be but is not limited to being applied to a camera device having at least a lens and a camera. The lens can be but is not limited to being used to protect the camera. In actual use, the lens can be but is not limited to being installed on a distributed shell, and the camera is installed in the shell, thereby making the camera waterproof and dustproof, and the camera collects images through the lens. Figure 2 is a schematic diagram of an optional camera device according to an embodiment of the present application, such as Figure 2 As shown, the target camera device in the embodiment of the present application includes at least two parts, namely a camera and a lens. In actual use, it may also include a shell, the camera is located inside the shell, and the lens is installed on the shell at the front end of the camera to protect the camera lens (such as waterproof and dustproof). The camera can collect images through the lens, and the distribution relationship between the lens and the camera in the embodiment of the present application (the angle direction and angle between the lens and the mirror surface of the camera, and the distance between the lens and the mirror surface of the camera) is adjustable.

[0034] In this embodiment, a method for eliminating ghost images is provided, which is applied to the above-mentioned computer terminal. Figure 3 : is a flow chart of an optical imaging method for eliminating ghost images according to an embodiment of the present application, the process includes the following steps:

[0035] Step S302, obtaining target object information within a target field of view of an initial camera device, wherein the target object information is used to indicate a distribution of target objects within the target field of view, and the initial camera device includes a lens and a camera, and the camera is used to capture an image of the target field of view through the lens;

[0036] Step S304, determining a target distribution relationship between the lens and the camera according to the target object information, wherein the target distribution relationship is used to eliminate a ghost image generated by the target object in an image captured by a target camera device;

[0037] Step S306: adjusting the initial camera device according to the target distribution relationship to obtain the target camera device.

[0038] Through the above steps, when the initial camera device including the lens and the camera is used to shoot the target field of view, the camera is used to collect images within the target field of view through the lens, and the target object information indicating the distribution of the target object in the target field of view of the initial device is obtained, so as to determine the target distribution relationship between the lens and the camera according to the target object information, and the target distribution relationship is used to eliminate the ghost image generated by the target object in the image collected by the camera device, and then the initial camera device is adjusted according to the target distribution relationship, and when the adjusted target camera is used to collect images within the target field of view, there is no ghost image corresponding to the target object in the image, thereby ensuring the quality of the image collected by the camera. The above technical solution solves the problem of low quality of images collected by the camera device in the related technology, and achieves the technical effect of improving the quality of images collected by the camera device.

[0039] In the technical solution provided in the above step S302, the target object information may include but is not limited to the position of the object, the brightness of the object, the size of the object, etc., and this solution does not limit this.

[0040] Optionally, in this embodiment, the target object is an object capable of outputting light, and the target object may include but is not limited to a light source, a reflective object, and the like.

[0041] In the technical solution provided in the above step S304, the target distribution relationship may include but is not limited to the angle relationship, position relationship, distance relationship, etc. between the lens and the mirror surface of the camera, and this solution does not limit this.

[0042] Optionally, in this embodiment, ghost image elimination is achieved by adjusting the position of the ghost image in the original image (the image within the target field of view captured by the initial camera device), which may include but is not limited to removing the ghost image from the image area, or moving the ghost image to the position of the target object in the image. Since the brightness of the target object in the image is greater than the brightness of the ghost image, the influence of the ghost image on the image is eliminated.

[0043] In the technical solution provided in the above step S306, the method of adjusting the initial camera can be achieved by adjusting the lens, adjusting the camera, adjusting the lens and the camera at the same time, etc. For example, the position of the camera is controlled to remain unchanged, and the angle of the lens is adjusted, thereby adjusting the angle between the lens and the camera in the camera device.

[0044] Figure 4 is an optional ghost image elimination schematic diagram according to an embodiment of the present application, such as Figure 4As shown, the target camera device used in the embodiment of the present application includes at least two parts: a camera and a lens. The lens is arranged at the front end of the camera to protect the camera from water and dust, etc. The target camera device is used to collect images within a target field of view with a target light source (corresponding to the target object mentioned above). The target light source (corresponding to the target object mentioned above) is located in the upper half of the field of view. When the image within the target field of view starts to be collected, the lens and the mirror surface of the camera are parallel (that is, the lens is not tilted relative to the camera). At this time, the image collected by the camera includes the target light source (corresponding to the target object mentioned above) and a ghost image corresponding to the target light source (corresponding to the target object mentioned above). The ghost image is caused by the lens reflecting the target light source in the camera. The light from the light source is re-reflected, and the resulting light beam is imaged on the imaging device of the camera. In order to eliminate ghost images, the positional relationship between the lens and the camera is changed to eliminate the influence of the light beam reflection reaction of the lens on the image captured by the camera, thereby eliminating the ghost image corresponding to the target light beam on the captured image. The positional relationship between the lens and the camera can be adjusted by, but is not limited to, adjusting the lens, adjusting the camera, or adjusting the lens and the camera at the same time. The adjustment can include, but is not limited to, adjusting the angle relationship and position relationship between the lens and the camera. As shown in the figure, in the embodiment of the present application, the inclination angle of the lens is adjusted to eliminate the ghost image corresponding to the target light source on the image captured by the camera.

[0045] As an optional embodiment, determining the target distribution relationship between the lens and the camera according to the target object information includes:

[0046] Determine a first area matching the object position within the target field of view, wherein the first area is a distribution area of ​​the target object within the target field of view, and the target object information includes the object position;

[0047] The target angle relationship between the lens and the camera is determined as the target distribution relationship based on the relationship between the first area and the center of the target field of view, wherein the target angle relationship is used to move the ghost image of the target object formed by the lens in the camera out of the target field of view.

[0048] Optionally, in this embodiment, the first area can be an area pre-divided in the target field of view, or can also be generated according to the object position. For example, when there are multiple target objects in the target field of view, the upper and lower areas of the target field of view can be pre-divided. In this case, when the object positions of the multiple target objects are in the upper half of the target field of view, the upper half of the target field of view is determined as the first area; or the area enclosed by the object positions of the multiple target objects in the target field of view can be used as the first area.

[0049] Optionally, in this embodiment, the target angle relationship can be determined based on the relative position relationship between the first area and the center of the field of view. For example, the direction of the angle between the lens and the camera mirror is determined based on the direction of the area center of the first area relative to the center of the field of view, and the angle between the lens and the camera is determined based on the maximum distance between the first area and the center of the field of view. This solution does not limit this.

[0050] Optionally, in this embodiment, the target angle relationship may include, but is not limited to, an angle and an angle direction between the lens and the camera mirror.

[0051] As an optional embodiment, determining the target angle relationship between the lens and the camera as the target distribution relationship according to the relationship between the first area and the center of the target field of view includes:

[0052] Determining the direction of the angle between the lens and the mirror surface of the camera according to the relationship between the first area and the center of the field of view of the target field of view;

[0053] The angle between the lens and the mirror surface of the camera is determined according to the field of view angle of the camera in the angle direction, wherein the target angle relationship includes the angle direction and the angle, and the ghost image of the target object formed by the lens and the camera distributed according to the angle direction and the angle falls outside the target field of view.

[0054] Optionally, in this embodiment, the angle direction can be but is not limited to being determined based on the direction of the first area relative to the center of the field of view, or it can also be determined based on the direction of a target point in the first area (such as the center point of the area) relative to the center of the field of view. This solution does not limit this.

[0055] Optionally, in this embodiment, the angle may be the maximum angle between the lens and the camera mirror in the angle direction, or may be an angle that matches the object position of the target object in the target field of view.

[0056] Figure 5 is a schematic diagram of an optional optical path when a ghost image is generated according to an embodiment of the present application, such as Figure 5As shown, the camera device used in the embodiment of the present application includes at least two parts: a lens and a camera. The lens is arranged at the front end of the camera to protect the camera. It can be but not limited to playing a role of waterproof and dustproof. When the camera device is used to collect images within the field of view of the camera, the light source beam (incident light 1) emitted by the target light source (corresponding to the target object mentioned above) in the field of view is captured by the lens into the camera and irradiated on the imaging device inside the camera, so that the image of the target light source appears on the collected image. When the light source beam (incident light 1) is irradiated on the imaging device, the imaging device will reflect the light source beam to obtain output light 1. The output light 1 is irradiated on the lens through the camera. The lens has a reflective effect on the irradiated output light 1. After the lens reflects the output light 1, incident light 2 is obtained. The incident light 2 enters the camera and irradiates on the imaging device, so that a ghost image corresponding to the target light source appears on the image collected by the camera.

[0057] Figure 6 is a schematic diagram of an optional optical path for eliminating ghost images according to an embodiment of the present application, such as Figure 6 As shown, the camera device used in the embodiment of the present application includes at least two parts: a lens and a camera. The lens is arranged in the front section of the camera to protect the camera. When there is a target light source (corresponding to the target object mentioned above) within the field of view of the camera, a light source image and a ghost image symmetrical to the position of the light source image will appear in the captured image at the same time, and the ghost image and the light source image have the center of symmetry with the center of the field of view. The present application changes the tilt angle of the lens relative to the camera in the direction of the ghost image (for example, the direction of the ghost image in the image relative to the light source image is the tilt direction; or the preset tilt direction matching the application scenario can be used as the tilt direction of the lens (for example, when the camera device is set at the rear of a car, since in this application scenario the light sources are all distributed in the upper half of the field of view, the matching tilt direction is up and down tilt; the camera is set in a wall scene, since in this scene the light sources are only distributed on the left or right side of the field of view, the matching tilt direction is left and right tilt)), so that an angle is generated between the camera and the lens. As shown in the figure, by controlling the lens to tilt in a specific direction and angle, the ghost image gradually deviates from the center of the image. The larger the tilt angle, the closer the ghost image is to the edge of the image, and the smaller the ghost image on the image. When the lens is tilted to a certain angle, all the ghost images in the image disappear.

[0058] Figure 7 is another optional optical path schematic diagram for eliminating ghost images according to an embodiment of the present application, such as Figure 7As shown, the camera device used in the embodiment of the present application includes at least two parts: a lens and a camera. The lens is arranged at the front section of the camera to protect the camera. When there is a target light source (corresponding to the target object mentioned above) in the field of view of the camera, the light source image and a ghost image symmetrical to the light source image will appear in the captured image at the same time, and the ghost image and the light source image are symmetrical with the field of view center. In the embodiment of the application, by adjusting the tilt direction and tilt angle of the lens, the position of the ghost image in the image is adjusted, so that the ghost image gradually approaches the image of the target light source (corresponding to the target object mentioned above), and finally the ghost image and the image of the target light source overlap, so that the ghost image corresponding to the target light source (corresponding to the target object mentioned above) cannot be displayed in the captured image, thereby eliminating the ghost image in the captured image.

[0059] As an optional embodiment, determining the angle direction between the lens and the mirror surface of the camera according to the relationship between the first area and the center of the field of view of the target field of view includes:

[0060] Determine, within the target visual field, a second area that is symmetrical to the first area relative to the center of the visual field;

[0061] The direction of the second area relative to the first area is determined as the angle direction.

[0062] Optionally, in this embodiment, the second area may be pre-divided in the target field of view, or may be generated based on the first area. For example, a center line passing through the center of the field of view may be set based on the application scenario of the target camera device, and the center line divides the field of view into two areas. The first area and the second area may be determined in the two areas based on the application scenario of the target camera. Alternatively, a reference object position symmetrical to the object position relative to the center of the field of view may be determined based on the object position of the target object in the target field of view, and the area enclosed by the reference object position in the target field of view may be used as the second area.

[0063] As an optional embodiment, determining the angle between the lens and the mirror surface of the camera according to the field of view of the camera in the angle direction includes:

[0064] Calculate the product value of the field of view angle and the target coefficient, wherein the target coefficient is a coefficient matching the target angle, and the target angle is the angle between the line connecting the target object and the center of the camera and the line connecting the field of view center and the center of the camera;

[0065] The angle is determined according to the sum of the product value and the target compensation value, wherein the target compensation value matches the camera and the angle is greater than or equal to the sum.

[0066] Optionally, in this embodiment, the target compensation value is a compensation value that matches the field of view angle of the camera, and different field of view angles correspond to different compensation values, thereby eliminating the influence of the field of view angle on ghost image elimination, thereby removing all ghost images from the captured image. The following table is an optional field of view angle and compensation value correspondence table according to an embodiment of the present application. As shown in Table 1, different field of view angles correspond to different compensation values.

[0067] Table 1

[0068]

[0069] Optionally, in this embodiment, the method for determining the angle includes directly determining the sum of the product value and the target compensation value as the angle, or selecting an angle value greater than the sum as the angle. For example, there may be a maximum adjustable angle between the lens and the mirror surface of the camera in the corresponding angle direction, thereby obtaining an angle range, the maximum adjustable angle being the upper limit of the angle range, and the calculated sum being the lower limit of the angle range. Any angle value falling within the angle range can be determined as the angle between the lens of the target device camera and the mirror surface of the camera. For example, in actual applications, there may be a certain initial angle between the lens and the mirror surface of the camera in the initial camera device, and the initial angle falls within the angle range. Therefore, the initial angle can be used as the angle between the lens and the mirror surface of the camera in the target camera device. At this time, adjusting the initial camera device to the target camera device only requires adjusting the direction of the angle between the lens and the mirror surface of the camera, without adjusting the angle of the angle.

[0070] Optionally, in this embodiment, there is a negative correlation between the target coefficient and the target angle, and the larger the angle value of the target angle is, the smaller the target coefficient is.

[0071] Figure 8 is a schematic diagram of an optional viewing angle according to an embodiment of the present application, such as Figure 8It is a front view of the camera device, and the camera's field of view angle FOV in the vertical direction is A. When the lens and the mirror surface of the camera are parallel, the image corresponding to the target object in the image captured by the camera and the ghost image are symmetrical relative to the center of the field of view. When the lens and the mirror surface of the camera are parallel, if the target object is located at the center of the field of view, the image corresponding to the target object and the ghost image coincide with each other. At this time, the angle between the line connecting the ghost image and the center of the camera and the line connecting the image boundary and the center of the camera is A / 2. The ghost image of the target object at the center of the field of view is eliminated by tilting the lens. At this time, the lens rotation angle is the largest to eliminate the ghost image (after the plane optical device is tilted, the center point of symmetry between the light source and the ghost image is changed so that the center point is located at half of the half-angle position, that is, the plane optical device is tilted A / 4). In view of the distortion of the lens, the glass tilt angle needs to increase a compensation value to compensate for the influence of distortion on FOV, so the compensation value needs to be increased, so as to determine that the angle that the lens needs to rotate to eliminate the ghost image is B, B≥A / 4+C, where C is the compensation value matching the camera's field of view angle.
