[0002] With the continuous development of intelligent wearable device technology, its application in various fields is increasingly widespread.In factory, logistics storage, urban traffic and other environments, the observation of the environment as employees or pedestrians often only rely on their own insight and vigilance, which can easily lead to accidents.Therefore, wearable intelligent monitoring devices with environmental monitoring and prompting functions, such as smart glasses, are increasingly widely used.

[0003] A type of existing wearable monitoring device integrates camera, sensor, display screen and wireless communication module components on smart glasses to realize the identification, processing and feedback of the surrounding environment information of the wearer.For the smart glasses of this type that already exist in the market, on the one hand, the technology of integrating multifunctional components on the glasses frame is not mature, and the structural design is unreasonable, resulting in low service life of smart glasses, poor wearing comfort and difficult application.On the other hand, the existing smart glasses technology is limited by the size and structure of the glasses and the field of view of the camera lens, focusing on forward environmental monitoring and identification, and it is difficult to provide a wider monitoring field of view.When a sudden situation occurs behind or to the side of the wearer, the monitoring field of view of the smart glasses is limited, which cannot prompt the wearer in time and can easily cause accidents. SUMMARY

[0004] Based on the above background, the purpose of the utility model is to design a smart glasses with wider monitoring field of view and more simplified structure for easy use to meet the needs of different personnel.

[0005] To achieve the above purpose, the utility model provides a wearable monitoring device, which comprises a display lens, a rear camera, a support structure and a main control circuit, wherein:

[0006] The first end of the support structure is connected to the display lens, and the second end of the support structure is connected to the rear camera.

[0007] The main control circuit is located inside the support structure and is electrically connected to the display lens and the rear camera.

[0008] The rear camera is used for shooting and collecting image data; the main control circuit is used for receiving and processing the image data collected by the rear camera and controlling the display lens to project information; the display lens is controlled by the main control circuit and is used for projecting information to the wearer.

[0009] The wearable monitoring device has the following advantages. On one hand, the rear camera is arranged at the rear end of the support structure to capture images, and the main control circuit is arranged in the support structure to process the captured image data, so that the environment information of the rear and the rear side of the wearer can be identified and monitored, and the monitoring field of view of the monitoring device is enhanced. On the other hand, the main control circuit controls the display lens to project important environment information, so that the wearer can be fed back the monitoring information without affecting the visual field range of the wearer, and the applicability of the monitoring device is enhanced.

[0010] It should be noted that the rear camera adopts the existing camera technology, and a common camera available on the market can also be directly selected.

[0012] In this implementation, two cameras are arranged as rear cameras to realize a wider rear monitoring field of view. Further, the two cameras are arranged to form an included angle with respect to the same horizontal plane to reduce the monitoring field of view blind area of the two cameras and provide more visual information. Moreover, the two cameras form an included angle to make the optical axes intersect, which can simulate binocular vision imaging of the human eye, and a clearer and more complete rear camera view can be obtained, so that stereoscopic vision and depth perception of the rear object or environment can be realized.

[0013] It should be noted that the two cameras simulate binocular vision imaging of the human eye, and the raw image information collected by the cameras also needs to be processed by combining conventional binocular vision image processing technology in the field. It should be understood that, by making the two cameras form an included angle and the optical axes intersect, the two cameras can capture a wider field of view and more obvious parallax raw images compared with conventional structural arrangements, which is beneficial to obtaining a clearer and more complete rear camera view by using conventional binocular vision image processing technology in the field.

[0026] In a possible implementation, the wearable monitoring device further includes a visual processing circuit, wherein: the visual processing circuit is located in the first connecting part; and the visual processing circuit is electrically connected with the control sub-circuit and the rear camera respectively.

[0027] In the implementation, the internal space structure of the first connecting part is used to arrange a circuit specially used for visual processing of image information captured by the rear camera, so as to reduce the operation burden of the control sub-circuit.
