The shooting direction of the camera is perpendicular to the plane object, and the optical central axis of the camera is overlapped with the central axis of the plane object, so that the situation that the shot image of the plane object is not deformed in the shooting range of the camera can be guaranteed.

After being refracted by the lens 13, at least part of the external light can be projected onto the photosensitive surface of the sensor chip 14, so that an image can be formed on the sensor chip 14.
The sensor chip 14 is electrically connected to the circuit board 11, the sensor chip 14 converts the photographed image information into a digital image signal through a photoelectric conversion function, and transmits the digital image signal to the circuit board 11, and the circuit board 11 transmits the digital image signal generated by the sensor chip 14 to an external connection device. The circuit board 11 may be configured to control the sensor chip 14 and transmit a digital image signal, and the specific circuit board 11 may be set according to a requirement, which is not limited in this embodiment of the application.
By setting the relative positions of the sensor chip 14 and the lens 13, the central axis 14a of the light-sensing surface of the sensor chip is parallel to the optical axis 13a of the lens, and the central axis 14a of the light-sensing surface of the sensor chip is offset from the optical axis 13a of the lens, that is, there is a preset offset distance between the central axis 14a of the light-sensing surface of the sensor chip and the optical axis 13a of the lens. The offset distance is a distance between the central axis 14a of the light-sensing surface of the sensor chip and the optical axis 13a of the lens.
It can be understood that, based on the optical imaging principle, the preset offset distance between the central axis 14a of the light-sensing surface of the sensor chip and the optical axis 13a of the lens may be determined according to the relative position of the object to be photographed and the camera, and the specific offset distance setting may be set according to the actual use requirement, which is not limited in the embodiment of the present application.
The sensor chip 14 may be selected from: a Charge Coupled Device (CCD) image sensor or a Complementary Metal-Oxide-Semiconductor (CMOS) image sensor, of course, the sensor chip 14 may also be another type of image sensor, which may be selected by a person skilled in the art according to actual needs, and the embodiment of the present application does not limit the present invention.
The light-sensing surface of the sensor chip 14 is generally a plane or an approximate plane, and the central axis 14a of the light-sensing surface of the sensor chip is a straight line that is perpendicular to the light-sensing surface of the sensor chip 14 and passes through the center of the light-sensing surface.
In this embodiment, the camera 10 may be applied to shoot a planar object, so that the central axis 14a of the light-sensing surface of the sensor chip in the lens holder 12 is staggered from the optical axis 13a of the lens, and based on the optical imaging principle, the planar object having a deviation with the optical axis 13a of the lens may be imaged on the light-sensing surface of the sensor chip 14, thereby realizing oblique shooting of the planar object by the camera 10, and an image obtained by oblique shooting may not be deformed.
It should be noted that the camera 10 provided in the embodiment of the present application may be applied to shoot a planar object, and may also be applied to shoot a non-planar object, which is not limited in the embodiment of the present application.
Referring to fig. 2, a schematic diagram of an imaging principle of the camera 10 provided in the embodiment of the present application is shown.
As shown in fig. 2, taking the object as a planar object, a first inclination angle θ 1 between the sensor chip 14 and the lens 13 in the camera 10 can be calculated according to an offset distance D1 between a central axis 14a of the photosensitive surface of the sensor chip and the optical axis 13a of the lens and a distance L1 between the sensor chip 14 and the lens 13, and the specific calculation formula is as follows:
tanθ1＝D1/L1 (1)
where θ 1 is a first inclination angle between the sensor chip 14 and the lens 13, D1 is an offset distance between a central axis 14a of the light-sensing surface of the sensor chip and an optical axis 13a of the lens, and L1 is a distance between the sensor chip 14 and the lens 13.
Accordingly, according to the offset distance D2 between the central axis 40a of the object and the optical axis 13a of the lens and the distance L2 between the object 40 and the lens 13, the second inclination angle θ 2 of the object 40 and the camera 10 can be calculated, and the specific calculation formula is as follows:
tanθ2＝d2/L2 (2)
where θ 2 is a second inclination angle of the object 40 and the camera 10, D2 is an offset distance between the central axis 40a of the object and the optical axis 13a of the lens, and L2 is a distance between the object 40 and the lens 13.
Based on the optical imaging principle, the first inclination angle θ 1 is equal to the second inclination angle θ 2, that is:
θ1＝θ2 (3)
the object 40 can be within the shooting range of the camera 10, and the camera 10 can shoot the object 40 in an inclined manner without distortion of the shot image.
Specifically, according to the above formulas (1), (2) and (3), specific parameter values of the offset distance D1 between the central axis 14a of the light-sensing surface of the sensor chip and the optical axis 13a of the lens, the distance L1 between the sensor chip 14 and the lens 13, the offset distance D2 between the central axis 40a of the object and the optical axis 13a of the lens, and the distance L2 between the object 40 and the lens 13 are adjusted, so that the angle sizes of the first inclination angle θ 1 and the second inclination angle θ 2 are adjusted to meet different inclination shooting requirements, and the camera 10 is not limited by the installation position when being installed and used, thereby improving the applicability of the camera 10.
In some embodiments, the lens 13 of the camera head 10 may include: one of a convex lens, a concave lens or a plane mirror or a combination of at least two of them. It should be noted that a specific lens 13 may be set according to lens parameters of the camera 10, where the lens parameters may include at least one of the following: focal length, depth of field, f-number, etc., of course, those skilled in the art can set the specific lens 13 according to actual needs, and the embodiment of the present application does not limit this.
Optionally, the optical size of the sensor chip 14 is smaller than the optical size of the lens 13.
In the embodiment of the present application, by setting the optical size of the sensor chip 14 and the optical size of the lens 13, since the optical size of the sensor chip 14 is smaller than the optical size of the lens 13, only a part of the light refracted by the lens 13 can be projected onto the photosensitive surface of the sensor chip 14 and imaged on the sensor chip 14, the difference between the optical size of the sensor chip 14 and the optical size of the lens 13 can be adjusted, and the imageable area of the camera 10 can be adjusted.
In the camera 10 according to the embodiment of the present application, the difference between the optical size of the sensor chip 14 and the optical size of the lens 13 can be set according to the size of the oblique shooting angle, and the shot object 40 needing oblique shooting is imaged by using the sensor chip 14, so as to meet the shooting requirements of different oblique angles. Moreover, the difference between the optical size of the sensor chip 14 and the optical size of the lens 13 can be determined according to the inclination angle of the camera for obliquely shooting the object, wherein the larger the inclination angle is, the larger the difference between the optical size of the sensor chip 14 and the optical size of the lens 13 is, and the larger the difference between the optical size of the sensor chip 14 and the optical size of the lens 13 is; otherwise, the difference is smaller.
The optical size of the lens 13 refers to the image plane size of the lens 13, and is used for representing the maximum clear imaging range of the lens 13, and the optical size of the sensor chip 14 refers to the target plane size of the sensor chip 14. The inclination angle is an angle between a line connecting the center of the subject 40 and the center of the lens 13 and the optical axis 13a of the lens.
It should be noted that, those skilled in the art may set the optical sizes of the sensor chip 14 and the lens 13 matched with the shooting scene according to the requirement of actual shooting, and the embodiment of the present application is not limited thereto.
Alternatively, referring to fig. 1 and 3, the optical axis 13a of the lens is disposed through the sensor chip 14; alternatively, the optical axis 13a of the lens is disposed so as to avoid the sensor chip 14.
In the embodiment of the present application, the relative positions of the sensor chip 14 and the lens 13 in the lens mount 12 may be set, so that the optical axis 13a of the lens passes through the sensor chip 14, or the optical axis 13a of the lens avoids the sensor chip 14, thereby meeting the shooting requirements of different inclination angles.
Specifically, the relative positions of the sensor chip 14 and the lens 13 in the lens mount 12 may be set, so that the central axis 14a of the photosensitive surface of the sensor chip is parallel to and staggered from the optical axis 13a of the lens, part of the light collected by the lens 13 may be imaged on the sensor chip 14, and when the camera is used, the object 40 to be photographed may be located in an image-formable area of the camera 10, and since the image-formable area of the camera 10 is staggered from the optical axis of the camera 10, oblique photographing may be implemented.
In some embodiments, as shown in fig. 1, the optical axis 13a of the lens may be set to avoid the sensor chip 14, and the offset distance between the central axis 14a of the light-sensing surface of the sensor chip and the optical axis 13a of the lens is relatively large, so as to increase the tilt angle of the tilt shooting of the camera 10.
In some embodiments, as shown in fig. 3, the optical axis 13a of the lens may be arranged to pass through the sensor chip 14, and the offset distance between the central axis 14a of the light-sensing surface of the sensor chip and the optical axis 13a of the lens is relatively small, so that the shooting range of the camera 10 can be increased while satisfying the oblique shooting of the camera 10.
It can be understood that the larger the offset distance between the central axis 14a of the light-sensing surface of the sensor chip and the optical axis 13a of the lens, the larger the inclination angle at which the camera 10 can be inclined for shooting, and the smaller the shooting range at which the camera 10 can shoot; conversely, the smaller the offset distance between the central axis 14a of the light-sensing surface of the sensor chip and the optical axis 13a of the lens, the smaller the tilt angle at which the camera 10 can tilt and photograph, and the larger the photographing range that the camera 10 can photograph. Therefore, a person skilled in the art can set appropriate positions of the sensor chip 14 and the lens 13 in the lens holder 12 based on the size of the shooting range and the size of the tilt angle of the tilt shooting, which is not limited in the embodiment of the present application.
Optionally, the angle of view of the lens 13 is equal to or greater than 60 degrees.
In the embodiment of the present application, since the inclination angle of oblique shooting needs to be reduced in order to increase the shooting range when the relative position of the sensor chip 14 and the lens 13 in the lens mount 12 is set, the maximum imaging range of the lens 13 can be increased by setting the angle of view of the lens 13 to 60 degrees or more, that is, by using the lens 13 with a larger angle of view, thereby increasing the oblique shooting range of the camera 10.
Specifically, the field angle of the lens 13 may be set to be greater than or equal to 60 degrees, and optionally, the field angle of the lens 13 may be selected from: any value such as 60 degrees, 65 degrees, 70 degrees, 75 degrees, 80 degrees, 85 degrees, 90 degrees, 95 degrees, 100 degrees, 118 degrees, etc., which is not limited in this application.
Optionally, the spherical distortion of the lens 13 is 3% or less. The distortion of the photographed image is reduced, thereby improving the quality of the photographed image of the camera 10.
Spherical distortion, also called barrel distortion or barrel distortion, is the barrel-shaped expansion distortion of the image caused by the physical properties of the lenses and the lens assembly structure. Spherical distortion refers to the degree of barrel distortion of the image of an object made by a lens relative to the object itself.
Specifically, the spherical distortion of the lens 13 may be set as: any numerical value such as 3%, 2.9%, 2.8%, 2.5%, 2%, 1.5%, 1%, 0.8%, 0.5%, etc., which is not limited in the examples of the present application.
Optionally, the lens 13 may be an aspheric lens 13, and by using the aspheric lens 13, the aberration of the lens 13 may be reduced, so as to avoid deformation of the captured image, thereby improving the quality of the captured image of the camera 10. Alternatively, the lens 13 may be an ultra-wide-angle lens 13, and by setting the lens 13 as the ultra-wide-angle lens 13, the field angle of the lens 13 may be increased, the imaging range of the lens 13 is increased, and thus the shooting range of the camera 10 is increased.
