Description

Technical Field

[0001] This invention relates to the field of big data processing, and more particularly to a military big data management system. Background Technology

[0002] Military vehicles such as automobiles and ships play a vital role in transportation and mobility, serving as protective equipment for occupants and conserving physical energy. However, in the design of military vehicles, the driver's visibility is often sacrificed to ensure their protective capabilities. Therefore, eliminating the driver's blind spots becomes crucial for vehicle management during maneuvers, ensuring the safety of both the vehicle and its personnel.

[0003] Chinese Patent Publication No. CN115328959A discloses a method, device, equipment, and storage medium for supplementing blind spot data of engineering vehicles. It utilizes a preset clock signal to acquire vehicle operation data; transmits the acquired vehicle operation data to a data processing server; if no feedback instruction is received from the data processing server, the acquired vehicle operation data is stored in a preset memory; and attempts are made to send the vehicle operation data in memory to a data service processor at preset time intervals until the data is successfully transmitted, thereby reducing the possibility of vehicle operation data loss due to partial transmission failure. Chinese Patent Publication No. CN115130045A discloses a method for calculating driver's blind spot. The method, device, vehicle, and medium utilize driver images captured by a camera module inside the vehicle facing the driver to identify eye-related regions and preset in-vehicle reference regions including feature points, and determine the driver's line-of-sight starting point set corresponding to the eye-related regions; after obtaining the actual coordinates of the feature points in a vehicle-defined coordinate system, calculate their second relative positional relationship with the driver's line-of-sight starting point set; calculate the coordinate set of the driver's line-of-sight starting point set based on the actual coordinates of the feature points and the second relative positional relationship; and calculate the driver's blind spot based on the coordinate set and the vehicle contour parameters corresponding to the driver's line-of-sight starting point set, thereby improving the accuracy of locating the driver's line-of-sight starting point and determining the blind spot in front of the vehicle. Chinese Patent Publication No. CN110316064A discloses a vehicle blind spot display system. Based on eye position information, the system processes the transparency of the image information displayed by the display unit, making the transparency of the non-visual blind spot greater than that of the visual blind spot. This allows the user to see information obscured outside the blind spot without affecting the information already present within it. Furthermore, although the transparency decreases when a blind spot exists, the transparency increases as the blind spot approaches the line of sight, better meeting practical needs.

The system first detects the blinking action area using the frame difference method, sets this area as the region of interest, and processes it using image morphology algorithms.

[0004] Therefore, the above technical solution has the following problems:

[0005] 1. Unable to identify blind spots caused by the vehicle's movement;

[0006] 2. It cannot effectively eliminate visual blind spots. Summary of the Invention

[0007] To address this issue, the present invention provides a military big data management system to overcome the problem in the prior art that the inability to identify and effectively eliminate visual blind spots caused by the maneuvering of vehicles leads to a decrease in the safety of vehicles during maneuvering.

[0008] To achieve the above objectives, the present invention provides a military big data management system, comprising:

[0009] The virtual module is used to simulate a first preset situation and a second preset situation and capture the head movement information of each driver when the corresponding situation occurs, including,

[0010] An environmental simulation unit is used to simulate the first preset condition through a first operating mode and to simulate the second preset condition through a second operating mode.

[0011] A virtual reality unit, which is connected to the environment simulation unit, is used to cooperate with the environment simulation unit to synchronously display the cockpit view image corresponding to the preset situation when the movement is generated.

[0012] A motion capture unit is mounted on the virtual reality unit to capture the driver's actions when the first preset situation and the second preset situation occur at a preset capture angle.

[0013] The collection module is used to collect the visual range of the driver while driving the vehicle, and to collect external information of the cockpit while the vehicle is in motion.

[0014] A display module is positioned in the cockpit in the main field of vision direction of the corresponding driver to display the corresponding image of the driver's blind spot;

[0015] The central control module is connected to the virtual module, the collection module and the display module. It is used to analyze the individual driver action information collected by the virtual module for each preset situation to obtain the driver's visual range information and generate the corresponding visual blind spot. It also controls the collection module to collect the visual blind spot image information of the corresponding driver according to the visual blind spot and controls the display module to provide the corresponding image of the visual blind spot to the corresponding driver.

[0016] The first preset state is the state of the cockpit when the vehicle vibrates up and down at a set frequency, and the second preset state is the state of the cockpit when the driver controls the vehicle to move, causing the vehicle to tilt at a set angle. The vehicle is a machine equipped with the cockpit and moved by the cockpit.

[0017] The first operating mode is that the driver's seat vibrates up and down, and the second operating mode is that the driver's seat tilts.

[0018] Furthermore, the collection module includes:

[0019] An in-cabin collection unit is installed inside the cockpit to collect the corresponding driver's head movements at the preset collection angle.

[0020] An external collection unit is located outside the cockpit to collect image information of the driver's blind spot.

[0021] Furthermore, the virtual reality unit displays the cockpit field-view images corresponding to the first preset state and the second preset state in a corresponding preset display order according to the preset action sequence of the environment simulation unit. At the same time, the motion capture unit collects the driver's eye movements in the first preset state and the second preset state and transmits them to the central control module. The central control module determines the driver's visual range and generates the driver's corresponding visual blind spot based on the driver's eye movements.

[0022] The visual range includes visual direction and field of view, which is related to the driver's vision. The blind spot is the area outside the visual range. The cockpit view image contains several trigger points that trigger the first preset condition and the second preset condition.

[0023] Furthermore, the central control module is provided with a first collection duration and a second collection duration. For the i-th driver, when the i-th driver reaches the first collection duration in the virtual module, the central control module determines that the i-th driver has reached a first preset state, and transmits the visual blind spots of the i-th driver in the first preset state and the second preset state to the collection module and the display module.

[0024] When the i-th driver reaches the second collection time in the cockpit, the central control module determines that the i-th driver has reached the second preset state, and adjusts the driver's visual blind spot corresponding to the first preset state and the second preset state according to the action information of the i-th driver collected by the collection module during the second collection time.

[0025] Where i = 1, 2, 3, ..., n, n > 3 and n is an integer, the first collection duration is the single running duration of the virtual module, the second collection duration is the corresponding duration of the preset adjustment cycle of the central control module, the first preset state is the corresponding state of a single driver reaching the first collection duration in the virtual module, and the second preset state is the corresponding state of a single driver reaching the second collection duration in the cockpit.

[0026] Furthermore, for the i-th driver, the motion capture unit acquires their field of vision under the first preset condition generated by several trigger points as simulated by the environment simulation unit. For the first preset condition generated by the j-th trigger point, the central control module sets the geometric center of the cockpit as the origin, takes the horizontal direction of the vehicle's travel direction as the x-axis, establishes a left-hand coordinate system, and sets the unit vector pointing from the j-th trigger point to the origin as the j-th trigger direction. The unit vector pointing from the geometric center of the field of vision of the i-th driver to the origin is: set up Where j = 1, 2, 3, ..., m, m > 5 and m is an integer, the central control module is provided with a first preset direction difference F α and the second preset direction difference F β , 0 < F α <F β The central control module will ΔF ij With F α and F β A comparison is made to determine the range of the blind spot that the first preset condition generated at the j-th trigger point creates for the i-th driver.

[0027] If ΔF ij ≤F α The central control module determines that the blind spot range generated by the first preset condition caused by the j-th trigger point for the i-th driver is within the allowable blind spot range.

[0028] If F α <ΔF ij ≤F β The central control module determines that the blind spot range of the i-th driver caused by the first preset situation generated by the j-th trigger point is within the flexible blind spot range.

[0029] If F β <ΔF ij The central control module determines that the blind spot range generated by the first preset condition caused by the j-th trigger point for the i-th driver is within the rigid blind spot range.

[0030] Wherein, the permissible blind zone range is the range within the edge of the field of vision of the i-th driver, the flexible blind zone range is the range that can be made visible from outside the edge of the field of vision of the i-th driver by installing optical devices in the cockpit and observing the optical devices, and the rigid blind zone range is the range that exceeds the permissible blind zone range and the flexible blind zone range.

[0031] Furthermore, when the environment simulation unit simulates the first preset condition generated at the j-th trigger point, the virtual reality unit displays a corresponding image. For the i-th driver, when observing the image displayed by the virtual reality unit, if the cockpit turns in the k-direction, the unit vector of the resultant force of the torque generated by the cockpit turning in that direction, as simulated by the environment simulation unit, is set to... Meanwhile, the motion capture module collects data corresponding to... In this case, the unit vector pointing from the geometric center of the i-th driver's field of vision to the origin is: set up The central control module is equipped with a third preset direction difference F. γ and the second preset direction difference F δ , 0 < F γ <F δ The central control module will ΔF ik With F γ and F δ A comparison is made to determine the extent of the blind spot created by the second preset condition resulting from the cockpit turning in the k direction for the i-th driver.

[0032] If ΔF ik ≤F γ The central control module determines that the blind spot range of the i-th driver caused by the second preset situation resulting from the cockpit turning in the k direction is within the allowable blind spot range;

[0033] If F γ <ΔF ik ≤F δ The central control module determines that the blind spot range of the i-th driver caused by the second preset situation resulting from the cockpit turning in the k direction is within the flexible blind spot range;

[0034] If F δ <ΔF ik The central control module determines that the blind spot range of the i-th driver caused by the second preset situation resulting from the cockpit turning in the k direction is within the rigid blind spot range.

[0035] Furthermore, if the central control module determines that the i-th driver has reached the first preset state, the central control module adjusts the orientation of the external collection unit of the vehicle operated by the i-th driver according to the rigid blind zone range corresponding to the i-th driver, and projects the entire rigid blind zone range of the i-th driver during the first collection time into the permissible blind zone range of the i-th driver through the display module.

[0036] Furthermore, the central control module controls the external collection unit to collect a single actual trigger point j' corresponding to the interference environment that can generate the first preset situation during the second collection time corresponding to the i-th driver. At the same time, the internal collection unit collects the unit vector of the geometric center of the field of vision of the i-th driver based on the second preset situation generated by the i-th driver's steering action k' in response to the single actual trigger point j' corresponding to the first preset situation. as well as

[0037] When the i-th driver reaches the second preset state, the central control module, in response to each of the... and each of the above The central control module is based on each of the above. and each of the above With the corresponding as well as Calculations are performed to determine the rigid blind spot visibility adjustment value ζi for the i-th driver, and the second preset directional difference F is adjusted based on ζi. δ The value of F is set. δ ' is the adjusted second preset direction difference, F δ '=F δ ×(1+ζi);

[0038] Where ζi is determined by equation (1):

[0039]

[0040] Wherein, θ is the adjustment coefficient for the rigid blind spot field of view, and its value is determined by the type of vehicle.

[0041] Furthermore, the central control module adjusts the size of the rigid blind spot field of view of the i-th driver according to the rigid blind spot field of view adjustment value ζi. At the same time, the central control module adjusts the geometric center of the rigid blind spot range of the i-th driver to ξi, where ξi is determined by equation (2):

[0042]

[0043] Wherein, λ is the adjustment coefficient of the geometric center of the rigid blind spot, and its value is determined by the height of the i-th driver.

[0044] Furthermore, when the central control module adjusts the rigid blind zone range of the i-th driver, it recalculates the second collection duration. When the second collection duration is reached again, the central control module adjusts the rigid blind zone range of the i-th driver.

[0045] Compared with the prior art, the beneficial effects of the present invention are that by setting up a virtual module, a collection module, a display module and a central control module, the driver's habits are obtained and the corresponding blind spots are determined according to the driver's habits. At the same time, the corresponding blind spots of the driver are displayed to eliminate the blind spots. This effectively improves the driver's ability to recognize the surrounding environment and effectively improves the safety of the vehicle during the maneuver.

[0046] Furthermore, by using virtual reality units, environment simulation units, and motion capture units to form a virtual module for driver training, the safety and reliability of training are effectively improved, thereby further enhancing the safety of the vehicle during maneuvering.

[0047] Furthermore, by collecting the driver's eye movements under various conditions, the driver's main field of vision can be determined. This not only effectively improves the action guidance of the field of vision but also enhances the accuracy of the driver's vision judgment, thereby further improving the safety of the vehicle during maneuvering.

[0048] Furthermore, by training drivers to preset the range of blind spots and periodically adjusting the blind spots of the corresponding drivers, the blind spot range and driver adaptability are effectively improved, thereby enhancing the safety of the vehicle during maneuvering.

[0049] Furthermore, by determining the permissible blind zone range, flexible blind zone range, and rigid blind zone range, the problem of blind zone visibility is addressed in a targeted manner based on the classification of blind zone range. This not only effectively improves the controllability of the blind zone range but also further enhances the safety of the vehicle during maneuvering.

[0050] Furthermore, by collecting data on the direction of blind spots caused by driver operation, the direction of blind spots can be determined, which not only effectively improves the targeting of blind spot range but also further enhances the safety of the vehicle during maneuvering.

[0051] Furthermore, by projecting the blind spot area into the driver's field of vision, the image of the blind spot on the driver is eliminated. This effectively reduces the danger of impact on the driver caused by the blind spot and further improves the safety of the vehicle during maneuvering.

[0052] Furthermore, by adjusting the size of the blind spot at regular intervals, the blind spot is adapted to the driver, which not only effectively improves the adaptability of the blind spot range but also further enhances the safety of the vehicle during maneuvering.

[0053] Furthermore, by adjusting the direction of the blind spot at regular intervals, the rationality of the blind spot direction is effectively improved, thereby enhancing the safety of the vehicle during maneuvering.

[0054] Furthermore, by continuously adjusting the blind spot range during driver use, the system and driver are made compatible, which not only effectively improves the robustness of the system but also further enhances the safety of the vehicle during maneuvering. Attached Figure Description

[0064] Please see Figure 1 As shown in the diagram, the military big data management system of the present invention includes:

[0065] The virtual module is used to simulate the first preset situation and the second preset situation and to collect the head movement information of each driver when the corresponding situation occurs.

[0066] The collection module is used to collect the visual range of the driver while driving the vehicle, and to collect external information of the cockpit while the vehicle is in motion.

[0067] The display module is positioned in the cockpit in the direction of the driver's main field of vision to display the corresponding image of the driver's blind spot;

[0068] The central control module, which is connected to the virtual module, the collection module and the display module, is used to analyze the individual driver action information collected by the virtual module for each preset situation to obtain the driver's visual range information and generate the corresponding visual blind spot. It also controls the collection module to collect the visual blind spot image information of the corresponding driver based on the visual blind spot and controls the display module to provide the corresponding image of the visual blind spot to the corresponding driver.

[0069] The first preset state is the state of the cockpit when the vehicle vibrates up and down at a set frequency, and the second preset state is the state of the cockpit when the driver controls the vehicle to move, causing the vehicle to tilt at a set angle. The vehicle is a machine equipped with the cockpit and moved by the cockpit control.

[0070] Please see Figure 2 As shown, it is a schematic diagram of the structure of the collection module of the present invention, including:

[0071] The in-cabin collection unit is located in the cockpit and is used to collect the corresponding head movements of the pilot at a preset collection angle.

[0072] The external collection unit is located outside the cockpit and is used to collect image information of the driver's blind spot.

[0073] By using virtual modules, data collection modules, display modules, and central control modules, the system acquires the driver's habits and determines the corresponding blind spots based on those habits. It then displays the corresponding blind spots to eliminate them, effectively improving the driver's awareness of the surrounding environment and enhancing the vehicle's safety during maneuvers.

[0074] Please see Figure 3 As shown, it is a structural schematic diagram of the virtual module of the present invention, including:

[0075] An environmental simulation unit is used to simulate the first preset condition through a first operating mode and to simulate the second preset condition through a second operating mode.

[0076] The virtual reality unit is connected to the environment simulation unit and is used to coordinate with the environment simulation unit to synchronously display the cockpit view image corresponding to the preset situation when the movement is generated.

[0077] A motion capture unit, which is mounted on the virtual reality unit, is used to capture the driver's actions when a first preset situation and a second preset situation occur at a preset capture angle.

[0078] The first operating mode is that the driver's seat vibrates up and down, and the second operating mode is that the driver's seat tilts.

[0079] By using virtual reality units, environment simulation units, and motion capture units to form a virtual module, drivers can be trained. This not only effectively improves training safety but also enhances training reliability, thereby further improving the safety of the vehicle during maneuvering.

[0080] Specifically, the virtual reality unit displays the cockpit view images corresponding to the first preset state and the second preset state in the corresponding preset order according to the preset action sequence of the environment simulation unit. At the same time, the motion capture unit collects the driver's eye movements in the first preset state and the second preset state and transmits them to the central control module. The central control module determines the driver's visual range and generates the driver's corresponding visual blind spot based on the driver's eye movements.

[0081] The visual range includes visual direction and field of view, which is related to the driver's vision. The blind spot is the area outside the visual range. The cockpit view image contains several trigger points that trigger the first preset condition and the second preset condition.

[0082] By collecting the driver's eye movements under various conditions, the system can determine the driver's main field of vision. This not only effectively improves the action guidance of the field of vision but also enhances the accuracy of the driver's vision judgment, thereby further improving the safety of the vehicle during maneuvering.

[0083] Specifically, the central control module is equipped with a first collection duration and a second collection duration. For the i-th driver, when the i-th driver reaches the first collection duration during training in the virtual module, the central control module determines that the i-th driver has reached the first preset state and transmits the visual blind spots corresponding to the i-th driver in the first preset state and the second preset state to the collection module and the display module.

[0084] When the i-th driver reaches the second collection time in the cockpit, the central control module determines that the i-th driver has reached the second preset state, and adjusts the driver's visual blind spot corresponding to the first preset state and the second preset state according to the action information of the i-th driver collected by the collection module during the second collection time.

[0085] Where i = 1, 2, 3, ..., n, n > 3 and n is an integer, the first collection duration is the single running duration of the virtual module, the second collection duration is the corresponding duration of the adjustment cycle preset by the central control module, the first preset state is the corresponding state of a single driver in the virtual module reaching the first collection duration, and the second preset state is the corresponding state of a single driver in the cockpit reaching the second collection duration.

[0086] By training drivers to preset the range of blind spots and periodically adjusting the blind spots for each driver, the blind spot range and driver adaptability are effectively improved, thereby enhancing the safety of the vehicle during maneuvering.

[0087] Please see Figure 4 As shown, it is a schematic diagram of the field of vision of the cockpit of the present invention.

[0088] When driver 2 is triggered by a single trigger point to produce a first preset condition while driving the vehicle, the trigger direction 3 points to the geometric center 1 of the cockpit. At the same time, a left-hand coordinate system is established based on the geometric center 1 of the cockpit, and there is a unit vector representing the trigger direction on the line 4 connecting the trigger direction 3 and the geometric center. At the same time, based on the position of driver 2, there are a field of vision range 5, a permissible blind spot range 6, a flexible blind spot range 7, and a rigid blind spot range 8. When judging the head movement of driver 2, based on the center of driver 2's field of vision, it can be determined that the trigger direction 3 is within the field of vision range of driver 2. At the same time, the display range of the corresponding display module of driver 2 is adjusted according to the field of vision range.

[0089] Specifically, for the i-th driver, the motion capture unit acquires their field of vision under a first preset condition generated by several trigger points, simulated by the environment simulation unit. For the first preset condition generated by the j-th trigger point, the central control module sets the geometric center of the cockpit as the origin, and the horizontal direction of the vehicle's driving direction as the x-axis to establish a left-hand coordinate system. The unit vector pointing from the j-th trigger point to the origin is set as... The unit vector pointing from the geometric center of the field of vision of the i-th driver to the origin is: set up Where j = 1, 2, 3, ..., m, m > 5 and m is an integer, and the central control module has a first preset direction difference F. α and the second preset direction difference F β , 0 < F α <F β The central control module will ΔF ij With F α and F β A comparison is made to determine the range of the blind spot that the first preset condition generated at the j-th trigger point creates for the i-th driver.

[0090] If ΔF ij ≤F α The central control module determines that the blind spot range of the i-th driver caused by the first preset situation generated by the j-th trigger point is within the allowable blind spot range.

[0091] If F α <ΔF ij ≤F β The central control module determines that the blind spot range of the i-th driver caused by the first preset situation generated by the j-th trigger point is within the flexible blind spot range.

[0092] If F β <ΔF ij The central control module determines that the blind spot range of the i-th driver caused by the first preset condition generated by the j-th trigger point is within the rigid blind spot range.

[0093] The permissible blind zone is the range within the edge of the i-th driver's field of vision. The flexible blind zone is the range that can be made visible from outside the edge of the i-th driver's field of vision by installing optical devices in the cockpit and observing the optical devices. The rigid blind zone is the range that exceeds both the permissible blind zone and the flexible blind zone.

[0094] By determining the permissible blind zone range, flexible blind zone range, and rigid blind zone range, the problem of blind zone visibility is addressed in a targeted manner based on the classification of blind zone range. This not only effectively improves the controllability of the blind zone range but also further enhances the safety of the vehicle during maneuvering.

[0095] Specifically, the virtual reality unit displays the corresponding image when the environment simulation unit simulates the first preset condition generated at the j-th trigger point. For the i-th driver, when observing the image displayed by the virtual reality unit, if the cockpit turns in the k-direction, the unit vector of the resultant force of the torque generated by the cockpit turning in that direction, as simulated by the environment simulation unit, is set to... Meanwhile, the motion capture module collects data corresponding to... In this case, the unit vector pointing from the geometric center of the i-th driver's field of vision to the origin is: set up The central control module is equipped with a third preset directional difference F γ and the second preset direction difference F δ , 0 < F γ <F δ The central control module will ΔF ik With F γ and F δ A comparison is made to determine the extent of the blind spot created by the second preset condition resulting from the cockpit turning in the k direction for the i-th driver.

[0096] If ΔF ik ≤F γ The central control module determines that the blind spot range of the i-th driver caused by the second preset situation resulting from the cockpit turning in the k direction is within the allowable blind spot range.

[0097] If F γ <ΔF ik ≤F δ The central control module determines that the blind spot range of the i-th driver caused by the second preset situation resulting from the cockpit turning in the k direction is within the flexible blind spot range.

[0098] If F δ <ΔF ik The central control module determines that the blind spot range of the i-th driver caused by the second preset situation resulting from the cockpit turning in the k direction is within the rigid blind spot range.

[0099] By collecting data on the direction of blind spots caused by driver operation, the direction of blind spots can be determined, which not only effectively improves the targeting of blind spot range but also further enhances the safety of the vehicle during maneuvering.

[0100] Specifically, if the central control module determines that the i-th driver has reached the first preset state, the central control module adjusts the orientation of the external collection unit of the vehicle operated by the i-th driver according to the rigid blind zone range corresponding to the i-th driver, and projects the entire rigid blind zone range of the i-th driver during the first collection time into the permissible blind zone range of the i-th driver through the display module.

[0101] By projecting the blind spot area into the driver's field of vision, the image of the blind spot on the driver is eliminated. This effectively reduces the danger of impact on the driver caused by the blind spot and further improves the safety of the vehicle during maneuvering.

[0102] Specifically, the central control module controls the external collection unit to collect a single actual trigger point j' corresponding to the interference environment that can generate the first preset situation during the second collection period corresponding to the i-th driver. At the same time, the internal collection unit collects the unit vector of the geometric center of the field of vision of the i-th driver according to the second preset situation generated by the i-th driver's steering action k' in response to the single actual trigger point j' corresponding to the first preset situation. as well as

[0103] When the i-th driver reaches the second preset state, the central control module will, for each and each and with the corresponding as well as Calculations are performed to determine the rigid blind spot visibility adjustment value ζi for the i-th driver, and the second preset directional difference F is adjusted based on ζi. δ The value of F is set. δ ' is the adjusted second preset direction difference, F δ '=F δ ×(1+ζi);

[0104] Where ζi is determined by equation (1):

[0105]

[0106] Where θ is the adjustment coefficient for the rigid blind spot field of view, and its value is determined by the vehicle category.

[0107] By periodically adjusting the size of the blind spot, the blind spot is adapted to the driver, effectively improving its adaptability and further enhancing the vehicle's safety during maneuvering.

[0108] Specifically, the central control module adjusts the size of the rigid blind spot field of view of the i-th driver according to the rigid blind spot field of view adjustment value ζi. At the same time, the central control module adjusts the geometric center of the rigid blind spot range to ξi, where ξi is determined by equation (2):

[0109]

[0110] Wherein, λ is the adjustment coefficient of the geometric center of the rigid blind spot, and its value is determined by the height of the i-th driver.

[0111] By periodically adjusting the direction of the blind spot, the rationality of the blind spot direction is effectively improved, and the safety of the vehicle during maneuvering is further enhanced.

[0112] Specifically, for the i-th driver, when the central control module completes the adjustment of the rigid blind spot range, the central control module recalculates the second collection time. When the second collection time is reached again, the central control module adjusts the rigid blind spot range of the i-th driver.

[0113] By continuously adjusting the blind spot range during driver use, the system and driver become mutually compatible, effectively improving the system's robustness and further enhancing the vehicle's safety during maneuvers.

[0114] The method for blind spot detection of military vehicles using the system of this invention is as follows:

[0115] Step S1: Train the system and the driver to determine the blind spot that will occur when the driver is hit during driving;

[0116] Step S2: The central control module records the impacts experienced by the driver during actual driving and the blind spots caused by the driver's maneuvering method, and displays the blind spot range during training in the driver's field of vision.

[0117] Step S3: After the central control module records the preset time, it adjusts the blind spot range data of the corresponding driver in the system to continuously adapt to the driver's operating habits, and displays the new blind spot based on the adjusted range data.

[0118] Taking a car as an example, the driver's visual direction is 0° from the cockpit orientation, deviating 12° counterclockwise. Their field of vision ranges from 0° to 30° clockwise and from 0° to 20° counterclockwise. Their permissible blind spot ranges from 30° to 35° clockwise and from 20° to 27° counterclockwise. Their flexible blind spot ranges from 35° to 45° clockwise and from 27° to 40° counterclockwise. The remaining area is their rigid blind spot range, which is from 40° to 235° counterclockwise.

[0119] During training, if a trigger point is activated at a 25° clockwise direction, the operator rotates the vehicle counterclockwise. The central control module determines that the trigger point is within the field of vision. The operator rotates the vehicle counterclockwise, causing the visual direction to change to a 20° counterclockwise deviation. The field of vision changes accordingly to a range of 0° to 20° clockwise and 0° to 30° counterclockwise. At this time, the rigid blind zone expands by 15° clockwise, i.e., 40° to 250° counterclockwise. Simultaneously, the geometric center of the blind zone also changes according to the change in the blind zone range.

[0120] For any vehicle, the flexible blind spot of the cockpit for the driver also includes the visual direction corresponding to the extension line of the control stick and the driver's eyes, and the area with the same field of vision as the driver's field of vision. The display module projects the rigid blind spot range onto this position.
