For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0029] With the continuous advancement of digital technology, traditional planar photogrammetry has shifted to digital photogrammetry. Digital photogrammetry uses panoramic cameras and lasers as tools to convert information about objects into digital form, and uses computers to process and analyze it to obtain the desired results data. Panoramic cameras usually need to set up antennas during use to achieve accurate geographic location positioning. In the prior art, the antenna is set close to the camera module, and the radio frequency noise generated by the camera module will interfere with the antenna, thereby reducing the antenna's performance in receiving satellite signals. In addition, the antenna setting position in the prior art usually has an adverse effect on the shooting field of view of the panoramic camera.

[0030] In order to solve the above technical problems, an embodiment of the present application provides a panoramic camera 100.

[0031] Reference Figure 1 , Figure 2 As shown, an embodiment of the present application provides a panoramic camera 100, including a protective shell 101, a camera module 102 and an antenna module 103; a noise shielding plate 104 is arranged in the protective shell 101, and the protective shell 101 is separated by the noise shielding plate 104 to form an upper chamber 105 and a lower chamber 106; the antenna module 103 is installed in the upper chamber 105, and the camera module 102 is installed in the lower chamber 106.

[0032] It should be noted that, in the embodiment of the present application, a noise shielding plate 104 is arranged in the protective shell 101 to divide the accommodation space formed by the protective shell 101 into two, so that an upper chamber 105 and a lower chamber 106 are formed in the protective shell 101. The upper chamber 105 is located directly above the lower chamber 106, that is, after being isolated by the noise shielding plate 104, an upper chamber 105 and a lower chamber 106 are stacked up and down.

[0033] The antenna module 103 of the embodiment of the present application is installed in the upper chamber 105, which is located directly above the camera module 102. By arranging the antenna module 103 above the camera module 102, it is not only convenient for the antenna module 103 to receive satellite signals, but also can prevent the antenna module 103 from causing adverse effects on the shooting field of view of the camera module 102.

[0034] It should be noted that the antenna module 103 is specifically a GNSS antenna module 103 .

[0035] The noise shielding plate 104 may be a metal plate, which is used to shield and isolate the radio frequency noise generated by the electronic components (such as the processor, power module, wireless communication module, etc.) inside the camera module 102 during operation. When these components are close to the GNSS antenna module 103 or share the same power line and ground plane, the noise will be coupled to the antenna signal path, interfering with the GNSS antenna module 103's reception of weak satellite signals.

[0036] Preferably, the noise shielding plate 104 can be horizontally disposed inside the protective housing 101 .

[0037] The camera module 102 of the panoramic camera 100 is usually provided with a plurality of camera lenses 114 spaced apart around the protective housing 101 on a horizontal plane to shoot the surrounding environment. When the noise shielding plate 104 is provided horizontally, it is convenient to install the camera module 102 and the antenna module 103.

The noise shielding plate 104 is used to isolate the radio frequency noise generated by the camera module 102 to avoid interference with the antenna module, thereby ensuring that the antenna module 103 has a strong signal receiving function.

[0041] In addition, the embodiment of the present application sets the antenna module 103 directly above the camera module, which is convenient for the antenna module 103 to receive signals. At the same time, the antenna module 103 does not interfere with the shooting field of view of the camera module 102, which is conducive to high-quality shooting of the camera module 102.

Those skilled in the art can set it according to the specific structural assembly requirements, and no special limitation is made here.

[0050] Illustratively, in the embodiment of the present application, a sealing ring groove 110 is provided on the fitting surface 109 of the upper shell 107, and a shell sealing ring is installed, so that the upper shell 107 and the lower shell 108 can be tightly fitted, so that the protective shell 101 formed by the upper shell 107 and the lower shell 108 can provide good sealing protection for the internal structure.

[0051] Similarly, in the embodiment of the present application, a sealing ring groove 110 is provided on the fitting surface 109 of the lower shell 108 , and a shell sealing ring is installed, so that the upper shell 107 and the lower shell 108 can be tightly fitted.

[0053] It should be noted that an assembly gap is formed between the lens 114 and the opening 113 , and a lens 114 sealing ring is sleeved on the lens 114 , and the lens 114 sealing ring is used to fill the assembly gap.

[0054] Further, the camera module 102 of the embodiment of the present application includes a camera bracket 111 and a camera body 112 mounted on the camera bracket 111. In the embodiment of the present application, a plurality of camera bodies 112 are arranged at intervals along the circumference of the camera bracket 111, so that the camera bodies 112 can take a panoramic photo of the surrounding environment of the camera bracket 111.

[0055] It should be noted that the specific number of the camera bodies 112 can be 4, 6, 8 or more, and those skilled in the art can set it according to needs.

[0056] Exemplarily, there are four camera bodies 112 , which are evenly arranged around the camera bracket 111 ; the main optical axis of the camera body 112 is set horizontally.

[0057] The embodiment of the present application is provided with four camera bodies 112, so that the weight of the entire device is light, which is conducive to providing a smaller protective housing 101. In other words, the embodiment of the present application can reduce the weight of the entire device, and at the same time make the panoramic camera 100 have a smaller volume, which is convenient for integration with laser and other equipment.

[0058] Reference Figure 3 , Figure 4 as well as Figure 5 As shown, as an optional embodiment, the noise shielding plate 104 has a first mounting surface 115 near the upper chamber 105, and the antenna module 103 is fixed to the first mounting surface 115 through a connecting structure; the noise shielding plate 104 has a second mounting surface 116 near the lower chamber 106, and the camera bracket 111 is fixed to the second mounting surface 116 through a connecting structure.

In addition, the above arrangement also facilitates integrated assembly outside the protective shell 101. After the assembly is completed, the module formed by the structure integrated on the noise shielding plate 104 is integrally mounted and fixed on the lower shell 108 or the upper shell 107, which is convenient for production assembly.
