[0074] Specifically, the laser scanner 6 and the spatial light modulator 7 are both mounted on the micro projector 8 and can both communicate with the micro projector 8, and both are mounted on the front end of the micro projector; by inserting the micro projector 8 carrying the laser scanner 6 and the spatial light modulator 7 into the slot 9 for fixation, the communication connection of the micro projector 8 with the camera base 2 or the image processing unit 3, etc. can be realized.

The spatial light modulator 7 receives the signal output by the image processing chip and converts it into light field information. The micro projector 8 is responsible for projecting the light field information combined with the point cloud data into the air to form a holographic image.

[0076] Optionally, the side surface of the micro projector 8 is further provided with a plug connector, which abuts against the inner wall of the slot 9, thereby realizing the fixation of the micro projector and the connection with the camera base 2.

[0077] Specifically, the side surface of the micro projector 8 is provided with a plug connector, which is inserted into the slot 9 to realize the installation and fixation of the micro projector 8, and after the plug connector is inserted into the slot 9, the laser scanner 6, the spatial light modulator 7 and the micro projector 8 can all realize the communication connection with the main camera unit 1 and the camera main body 30.

[0078] In another embodiment, the holographic projection module 40 is inserted into the slot 9 as a whole (which can be referred to as a memory card or a SIM card), to realize the protection of the holographic projection module 40 by the camera base 2 and to reduce the volume of the camera. At this time, a projection port is further arranged at the front end of the camera base 2, and the micro projector 8 projects the light field information into the air through the projection port.

[0079] In an embodiment, the camera further comprises an adjusting assembly (not shown in the figure); the adjusting assembly comprises a support plate, an extension shaft and a universal adjusting valve; one end of the extension shaft is connected with the universal adjusting valve, and the other end is connected with the support plate; the universal adjusting valve is connected with the camera main body 30 to adjust the angle and orientation of the camera.

[0080] Specifically, the universal adjusting valve of the adjusting assembly is installed in the universal adjusting valve mounting structure arranged on the back of the fixed support 4 of the fixed assembly 31 in the camera main body 30, and when the connection unit 5 is connected with the smart terminal in a wired manner such as a USB interface, the connection unit 5 can also be extended (such as a cable with a reserved target length, or extended through a mechanical structure), so that the camera can be adjusted up, down, left and right through the universal adjusting valve, and the camera can be rotated to change the projection position of the camera during the holographic projection process without manually moving the smart terminal, or to move the projection during the projection process.

[0081] After the smart terminal is connected with the camera, a holographic projection smart terminal can be obtained, which can convert a two-dimensional plane image into a three-dimensional holographic image and perform holographic projection.

[0082] For example, after the user connects the mobile phone with the camera, the camera is automatically initialized to ensure the power supply of the camera and the establishment of the data transmission channel between the camera and the smart terminal. After the connection, the smart terminal transmits content data to the camera through the connection unit 5 connected thereto; the image processing unit 3 carried by the camera can perform optimization processing on the content data transmitted by the smart terminal or the data collected by the main camera unit 1, such as image enhancement, color correction and instruction recognition (confirming instructions by recognizing user gestures through the camera), and convert the data into a format suitable for holographic projection. The spatial light modulator 7 can modulate the laser beam to form a holographic image with depth, which is projected into space. The image sensor built in the image processing unit 3 can also recognize user gestures to perform interactive operations such as zooming in, zooming out and moving the projection screen (the data can be collected by the main camera unit 1 or the smart terminal camera), and update the projection screen in real time in response to the interactive operations; feedback can also be provided through highlighting or sound, so that the user can have an intuitive interactive experience without touching the screen.

[0083] For example, a teacher can use a mobile phone + camera to display a complex 3D model or experiment process in the classroom to help students better understand abstract concepts. Students can interact with the projection content through gestures, such as rotating and scaling the model to observe the details from different angles. Through holographic projection technology, students can also perform virtual experiments on the mobile phone to simulate real experimental environments and operation steps, improving experimental skills and safety.

[0084] For example, tourists can use a mobile phone + camera for virtual travel, and understand the history and culture, customs and other information of the destination through projection. At the same time, museums and tourist attractions can also use this technology to provide interactive tour services and improve the visiting experience of tourists.

[0085] For example, brand merchants can use holographic projection technology to create attractive advertising content using a mobile phone + camera, and project it in shopping malls, exhibitions and other places through a mobile phone + camera to attract customers' attention and improve brand image.

[0086] For example, architects and urban planners can use the holographic projection technology of the mobile phone + camera combination to display building models or urban planning schemes, interact with the projection content through gestures, and simulate the effects of different design schemes. This helps them more intuitively understand the spatial layout and visual effects of the design scheme, and improves design efficiency and quality.

[0087] The camera provided by the embodiment can be detachably mounted on the back of the intelligent terminal, can project two-dimensional content in three-dimensional form, and can realize projection and interaction with the user by collecting image data through the main camera unit. The camera is small in size and easy to carry, and can be removed from the intelligent terminal when not in use.

[0088] As shown in Figure 4 The application also provides an intelligent terminal, which is provided with a projection interface cabin on the back of the intelligent terminal. The projection interface cabin includes a cabin door 23 and a mounting assembly arranged in the projection interface cabin 20.

[0089] The mounting assembly includes a buckle 21 and a connection port 22 (such as a USB connection port or a wireless Bluetooth connection module, which corresponds to the connection unit 5 on the camera). The projection interface cabin 20 is communicatively connected to the camera in the above embodiment through the connection port 22, and is detachably connected and fixed with the fixed buckle of the camera as described in the above embodiment through the buckle 21.

[0090] For example, the appearance of the mobile phone: a small sliding cover interface cabin is designed in the center of the back of the mobile phone. The cabin door is made of lightweight high-strength material, and the surface is treated with frosted processing to improve the feel and prevent fingerprints from remaining. The cabin is equipped with a USB interface and a buckle to ensure that the camera module is inserted stably and easily replaced.

[0091] For example, when connecting the camera, open the cabin door 23 of the projection interface cabin. The cabin is equipped with a USB interface and a buckle to ensure that the camera module is inserted stably and easily replaced.

[0092] The application further provides a smart terminal shell, comprising a shell, a projection interface cabin and a communication connection unit arranged on the shell, the projection interface cabin being connected with the smart terminal through the communication connection unit; the projection interface cabin comprises a cabin door and a mounting assembly arranged in the projection interface cabin; the projection interface cabin is detachably connected with the camera according to the above embodiments through the mounting assembly.
