In this way, when observing the fingering of a student playing the piano, the observation is not clear because the shooting distance is relatively far, and the face can only see the side face of the student, and the student's complete expression cannot be observed.

[0029] An auxiliary imaging device provided by an embodiment of the utility model is described in detail below with reference to the accompanying drawings.
[0030] It should be clear that the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0031] Figure 1 A schematic diagram of an imaging device provided by an embodiment of the utility model. Figure 1 As shown, the auxiliary imaging device of this embodiment may include:
[0032] The first optical path component 11 is used to receive a first path of light reflected from a first target area, and transmit the first path of light to be output along a first direction;
[0033] The second optical path component 12 is used to receive the second light reflected by the second target area and transmit the second light to be output along the first direction; wherein the first target area and the second target area are different areas of the same target object, or the first target area and the second target area are areas on different target objects respectively.
[0034] For example, in one embodiment of the utility model, during remote piano teaching, the teacher needs to observe the facial expressions and hand movements of the students through a camera. The students can install the auxiliary imaging device on the camera, align the first target area with their own face, and align the second target area with their own hands. The first optical path component receives the light reflected from the face, and the second optical path component receives the light reflected from the hands. The first optical path component and the second optical path component output the received light to the camera along a first direction, thereby achieving the purpose of the teacher observing the details of the two target areas of the students through one camera.
[0035] The auxiliary imaging device provided by the embodiment of the utility model receives the first path of light reflected by the first target area through the first optical path component, and transmits the first path of light to be output along the first direction; the second optical path component receives the second path of light reflected by the second target area, and transmits the second path of light to be output along the first direction; wherein the first target area and the second target area are different areas of the same target object, or the first target area and the second target area are areas on different target objects. In this way, the images of different target areas are finally output along the first direction, achieving the purpose of obtaining images of two target areas in one camera.
[0036] Optionally, in one embodiment of the utility model, the first optical path component includes a first lens and a first light transmission component, the first lens is used to receive a first light reflected from a first target area, and transmit the first light to the first light transmission component, and the first light transmission component transmits the first light to be output along a first direction; and / or the second optical path component includes a second lens and a second light transmission component, the second lens is used to receive a second light reflected from a second target area, and transmit the second light to the second light transmission component, and the second light transmission component transmits the second light to be output along the first direction.
[0037] The angle between the optical axis of the first lens and the optical axis of the second lens is greater than 10° and less than 180°. When the angle between the optical axis of the first lens and the optical axis of the second lens is within 10°, the image details in the two target areas can be displayed with one lens, and the device is generally not needed. When the angle between the optical axis of the first lens and the optical axis of the second lens is greater than 10° and less than 180°, such as when the angle is 30°, 55°, or 100°, it is difficult to obtain the image details of the corresponding two target areas with only one lens. At this time, the image details of the two target areas can be observed by using the auxiliary imaging device.
[0038] Optionally, in an embodiment of the present invention, the first lens and / or the second lens is a fisheye lens. The fisheye lens is a special lens in the ultra-wide-angle lens, and the fisheye lens can be used to obtain images within a wider viewing angle range.
[0039] Optionally, in one embodiment of the utility model, the first light transmission component includes a first prism and a second prism; the first light emitted from the first lens is reflected by the first reflection surface of the first prism to the second reflection surface of the first prism, reflected by the second reflection surface of the first prism to the first reflection surface of the second prism, reflected by the first reflection surface of the second prism to the second reflection surface of the second prism, and the first light is reflected by the second reflection surface of the second prism to the first direction.
[0040] For example, Figure 2As shown, a schematic diagram of an imaging optical path of a first optical path component provided by an embodiment of the utility model includes a first light transmission component 21 and a fisheye lens 22. The first light transmission component 21 includes a first Porro prism 211 and a second Porro prism 212.

The upper bevel reflects the light to the lower bevel of the first Porro prism 211. The lower bevel of the first Porro prism 211 reflects the light to the upper bevel of the second Porro prism 212.
