Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of polar operation assistance, in particular to a wearable visual imaging system and control method for polar dim light environment, which is suitable for polar scientific exploration, resource exploration and other scenes, and assists operators to realize precise environmental perception and free movement in extreme dim light environment. BACKGROUND

[0002] In polar scientific exploration, resource exploration and related operation activities, extreme environmental conditions are always the core factors restricting operation efficiency and safety, among which the visual limitation problem caused by polar night and continuous dim light environment is particularly prominent. Due to the influence of the earth's revolution and rotation, during the long polar night, natural light almost disappears, and the environmental brightness is often lower than 0.1 lux, even approaching zero. Even in the dim light period of non-polar night, due to the extremely low solar elevation angle, weak and single spectrum of ice and snow reflected light, the human eye visual resolution is greatly reduced, and the identification ability of obstacles, terrain undulations and operation targets is seriously insufficient.

[0003] This kind of extreme dim light environment brings great challenges to the free movement of operators: on the one hand, the traditional way of relying on natural light or ordinary lighting equipment cannot meet the needs - strong light illumination not only causes ice and snow glare, destroys the dark adaptation ability of the human eye, but also forms a "visual blind area" due to the limited range of light, which cannot realize panoramic perception of the surrounding environment, and the polar night cannot see the surrounding environment, so people cannot move freely within a certain range; on the other hand, the existing mobile assistance equipment is mostly designed for conventional low light environment, such as night vision instrument which can enhance dim light imaging, but has defects such as narrow field of view, distorted depth perception, and inability to fuse real-time three-dimensional environmental information, and most of the equipment is bulky and poor in portability, which is difficult to adapt to the scene of frequent movement and flexible operation in polar operation, and cannot realize three-dimensional visual presentation of the environment based on real-time positioning.

[0004] At present, in the polar dim light environment, there is no wearable assistance system that can balance portability, panoramic environmental perception, real-time positioning and three-dimensional visual imaging. Operators often have to rely on experience to move slowly, or use primitive methods such as multi-person cooperation and rope traction to ensure safety, which not only seriously restricts the operation radius and efficiency, but also greatly increases the risk of accidents such as falling, colliding with ice layer cracks, etc.

[0005] In the prior art, a sea area search system and a three-dimensional environment immersive experience VR intelligent glasses disclosed in patent document (CN110809148A) rely on ship terminal to collect data, the equipment design is for sea area environment, without considering the influence of polar low temperature and micro light on image collection, and the signal is transmitted through communication satellite, the signal stability is poor in the complex terrain of the polar region, there is no image preprocessing mechanism in the micro light environment, and the polar micro light scene cannot be adapted. The polar environment medical data monitoring method, system, device and medium disclosed in patent document (CN118806250A) focus on polar medical data monitoring, the core is physiological parameter collection and signal enhancement, and the visual imaging function is not involved, the wearable device can only process physiological data, and the environmental perception problem cannot be solved, and the signal enhancement device is only for medical signal, and is not matched with the visual data transmission demand.

[0034] The application will be described in detail below in combination with the drawings and specific embodiments. The embodiments are implemented on the premise of the technical solutions of the application, and detailed implementation modes and specific operation processes are given, but the protection scope of the application is not limited to the following embodiments.

[0035] Embodiment 1

[0036] A system for wearable visual imaging in a polar low-light environment, as shown in Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , comprising: a polar low-light environment 1, a signal base station 2, a signal coverage area 3, a research station or camp 4, an augmented reality VR glasses 5, a data collector 51, a three-dimensional visual imaging controller 52, a glasses battery 53, and a positioner 6.

[0037] The signal base station 2 defines the range of the signal coverage area 3, provides a spatial boundary for the movement range of the operator, and the positioner 6 is equipped with a wireless receiving device, which obtains the spatial position information of the augmented reality VR glasses 5 in real time, and ensures the positioning accuracy of the operator in the signal coverage area. The augmented reality VR glasses 5 as the core wearable device, a plurality of data collectors 51 are arranged on the front face, can efficiently receive image data in the polar low-light environment 1, and through the built-in program, the data is preprocessed such as denoising and contrast adjustment, and at the same time, real-time transmission is realized. The three-dimensional visual imaging controller 52 on the augmented reality VR glasses 5 can analyze and display the three-dimensional visual image of the current position in real time based on the preprocessed image data and the position signal of the positioner 6, and complete the visual presentation of the environmental information. The glasses battery 53 at the temple is designed to be detachable, which provides continuous power supply for the equipment to adapt to long-term polar operation.

[0038] The functions and specific implementation modes of the components of the application are described as follows:

[0039] In the ice layer operation area around a certain research station in the polar region, during the polar night period, it is consistent with the polar low-light environment 1 targeted by the application. At this time, ice layer thickness measurement operation is required in this area, and the operator wears the augmented reality VR glasses 5 of the application and carries the positioner 6 to carry out work.

[0040] First, a plurality of signal base stations 2 are arranged around the work area, each of which is equipped with a wireless transmitting device to cooperatively define a signal coverage area 3 within which the operator's movement and work will be performed. The augmented reality VR glasses 5 worn by the operator have a plurality of data collectors 51 mounted on the front thereof, and these data collectors 51 store specific programs therein and are capable of processing image data received in the low-light environment. Meanwhile, a glasses battery 53 is mounted at the temple of the augmented reality VR glasses 5 to provide power support for the operation of the entire glasses, and the battery is of a detachable structure to facilitate the operator to replace it when the power is insufficient.

[0041] When the operator starts work, the locator 6 receives signals transmitted by the signal base station 2 in real time through its own wireless receiving device, thereby determining the specific position of the augmented reality VR glasses 5 and transmitting the position information to the three-dimensional visual imaging controller 52 in real time. The three-dimensional visual imaging controller 52 is mounted on the augmented reality VR glasses 5 frame and in the middle of the data collector 51, and it also stores corresponding programs therein.

[0042] The data collector 51 continuously receives image data around the work area during the work process, and simultaneously loads programs to perform preprocessing steps, such as denoising and adjusting contrast, on the collected environmental data such as ice layer and snow ground, and transmits the processed real-time data to the three-dimensional visual imaging controller 52. After the three-dimensional visual imaging controller 52 loads the program, it combines the position signal transmitted by the locator 6 and the preprocessed data transmitted by the data collector 51 to perform real-time analysis on the visual image information of the current position, and then displays the three-dimensional image results obtained by the analysis on the augmented reality VR glasses 5. The operator can clearly see the three-dimensional image of the surrounding environment through the glasses, and then freely move within the signal coverage area 3 to smoothly carry out the ice layer thickness measurement work.

[0043] The working principle and working process of the embodiment are described as follows:

[0044] The working principle of the embodiment is to realize visual assistance in the polar low-light environment through the cooperative mechanism of "spatial range definition - position tracking - low-light data collection and processing - three-dimensional image presentation". Specifically, the signal base station defines the boundaries of the work space by means of wireless signals, the locator captures the position of the augmented reality VR glasses in real time and synchronizes it to the three-dimensional visual imaging controller; the data collector collects original images in the low-light environment, transmits the preprocessed data to the three-dimensional visual imaging controller, the latter fuses the position information and the processed data, generates real-time three-dimensional images and displays them through the augmented reality VR glasses, thereby providing the operator with environmental perception and movement guidance.

[0045] The specific working process is as follows:

[0046] First, a plurality of signal base stations start the wireless transmitting device to form a signal coverage area through signal superposition, and clearly define the operation boundary; after the operator wears the augmented reality VR glasses, the detachable battery at the glasses leg supplies power, the locator continuously receives the signal base station signal through the wireless receiving device, calculates and transmits the current position coordinates of the glasses in real time, and meanwhile, the two data collectors on the front of the glasses start to capture the surrounding image data in the polar night environment, and the loading program eliminates interference through denoising and contrast adjustment; then, the three-dimensional visual imaging controller receives the preprocessed image data and positioning information, analyzes and generates a three-dimensional environment image containing the current position of the operator through the built-in program, and displays the image on the glasses lens in real time, so that the operator can freely move and carry out operation in the signal coverage area, and the device continuously updates the image and position information during the process.

[0047] The preferred embodiments of the present application are described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations without creative work based on the concept of the present application. Therefore, any technical solutions obtained by logical analysis, reasoning or limited experiments based on the prior art within the concept of the present application should be within the protection scope determined by the claims.
