After the real environment and the virtual object are overlapped, the real environment and the virtual object can exist in the same picture and space at the same time.

Referring to fig. 1, an AR smart helmet 10 according to an embodiment of the present disclosure mainly includes an AR display module 100, a position indicator 210, an ambient light detection module 310, and a time determination module 320. The AR smart helmet 10 mainly includes a helmet body and a strap, the helmet body is fixed on the head of a user through the strap, and the helmet body is used for protecting the head of the user when the user is impacted from the outside.

AR display module 100 can be through the AR technique with the notice, message and characters are projected to the user in front of, and AR display module 100 is configured to show one or more in navigation information, gesture information rides, meteorological information, helmet system function information, that is to say, AR display module 100 can only be used for showing gesture information rides to the user of AR intelligent helmet 10, also can be used for showing gesture information rides and navigation information to the user of AR intelligent helmet 10, still can be used for showing navigation information, gesture information rides, meteorological information and helmet system function information to the user of AR intelligent helmet 10. The display time and the display style of the information are set in advance through a program, and when the display time is met, the AR display module 100 displays the acquired or obtained corresponding information after logical operation in an AR mode so as to be conveniently seen by a user.

The AR display of navigation information may include travel routes and turn-around prompts, among other things. The AR display of the riding posture information may include contents of a current traveling speed, acceleration, direction, and the like, and if the user is driving the electric bicycle, the riding posture information corresponds to the traveling posture information. The AR display of weather information may include current temperature, humidity, and barometric pressure, among other things. The AR display of the helmet system function information may include contents such as the remaining power and the remaining storage capacity of the helmet. The AR display module 100 may also display entertainment information, and the AR display of the entertainment information may include the currently played song, volume, and play mode. Since the AR smart helmet 10 may be used as a helmet of a take-out delivery person, the AR display module 100 may further display take-out delivery information, and the AR display of the take-out delivery information may include contents such as a store name, a store location, a ticket number, a buyer location, a buyer name, and a buyer contact address.

The position indicator lamp 210 is installed on the AR smart helmet 10, that is, on the helmet body of the AR smart helmet 10, and may be specifically installed at the highest position outside the helmet body, so that it is also called a high-position indicator lamp for indicating the existence and position of the helmet user to the rear, and avoiding collision of the surrounding vehicles or other traveling objects due to the failure to see the user clearly.

The ambient light detection module 310 is integrated on the AR smart helmet 10 and may be built into the AR smart helmet 10. The ambient light detection module 310 is configured to detect the ambient light intensity and trigger the position cue light 210 to illuminate when the ambient light intensity is below a preset light intensity threshold. Specifically, the ambient light detection module 310 may detect the ambient light intensity of the outside world in real time or periodically, and compare the ambient light intensity with a preset light intensity threshold. If the ambient light intensity is lower than the preset light intensity threshold, it indicates that the external ambient brightness is low, and the user's presence is difficult to be observed and perceived by the outside, so the position warning lamp 210 is turned on to externally warn the helmet user's presence; if the ambient light intensity is not lower than the preset light intensity threshold, it indicates that the ambient brightness is high, and the user can be observed and perceived by the outside easily without the help of the position indicator 210, so the ambient light detection module 310 does not trigger the position indicator 210 to be turned on.

Further, the ambient light detection module 310 may include a photosensitive element, and the ambient light detection function is implemented by the photosensitive element constituting the light detection circuit. The photosensitive element can be an analog photosensitive element or a digital photosensitive element, wherein when the analog photosensitive element is selected, the linear voltage output by the photosensitive detection circuit can be linearly changed along with the illumination intensity from dark to bright, and the range of the linear voltage can be 0-3.3V. The ambient light detection module 310 may convert the linear voltage to obtain an ambient light intensity, and then compare the ambient light intensity with a preset light intensity threshold. When selecting for use numerical value formula photosensitive sensor, photosensitive detection circuit directly converts illumination intensity into the digital quantity, through interface connection to environment light detection module 310, and environment light detection module 310 analyzes data, and then realizes the comparison of environment illumination intensity and preset light intensity threshold value.

The time determination module 320 is also integrated on the AR smart helmet 10 and may be built into the AR smart helmet 10. The time determination module 320 is configured to trigger the position indication lamp 210 to light up when the current time is within a preset time period so as to indicate the self position to the outside. Specifically, the time determining module 320 may obtain the current time in real time or periodically according to the configured timing function, and determine whether the current time enters the preset time period. The preset period is set in accordance with the sunset time, and for example, a period from the sunset time to the next sunrise time may be taken as the preset period. If the current time is eleven hours at night, that is, the current time is within the preset time period, the time determination module 320 triggers the position indication lamp 210 to be turned on, so as to indicate the presence of the user to the outside in a dark or even dark environment; if the current time is ten am, the current time is outside the preset time period, which indicates that the user can be observed and detected by the outside without using the position indicator 210, and therefore the time determination module 320 does not trigger the position indicator 210 to be turned on.

Furthermore, the sunset time and the sunrise time can be determined according to the geographical location of the user, and the sunset time and the sunrise time of different geographical locations are different, so that the current sunset time and the current sunrise time can be determined according to the location, so that the trigger time of the position prompt lamp 210 by the time determination module 320 is more consistent with the real scene.

It should be noted that the ambient light detection module 310 and the time determination module 320 are both capable of triggering the lighting of the position indicator lamp 210, and the ambient light detection module 310 and the time determination module 320 form a lighting control set of the position indicator lamp 210. Referring to fig. 2, one specific determination process for lighting the position indicator 210 may be: if any module in the lighting control set triggers the lighting of the position prompt lamp 210, the position prompt lamp 210 is lighted; if a plurality of modules in the lighting control set trigger the lighting of the position prompt lamp 210, the position prompt lamp 210 is turned on; if no module in the lighting control set triggers the lighting of the position warning light 210, the position warning light 210 is turned off.

The control relationship between the ambient light detection module 310 and the time determination module 320 for the position indicator light 210 is described below by taking as an example a scenario in which the user wears the AR smart helmet 10 for cycling.

Assuming that the current time is ten o' clock in the morning, the time determination module 320 does not trigger the position indicator 210 to be turned on, if the rider enters the tunnel and the surrounding environment becomes dark, the ambient light detection module 310 triggers the position indicator 210 to be turned on through the detection of the ambient light intensity, and when the ambient light detection module 310 avoids controlling the position indicator to be turned on and off only by the sunset time, other vehicles do not adapt to the environment or have unclear sight lines due to entering the dark environment suddenly and then have rear-end accidents with the user.

Assuming that the current time is eleven points at night, the ambient light detection module 310 and the time determination module 320 both trigger the position indicator lamp 210 to be turned on, at this time, the external vehicle is closer to the user and the vehicle lamp illuminates the sensor of the ambient light detection module 310 for detecting the external light intensity, so that the ambient light intensity detected by the ambient light detection module 310 is higher than the preset light intensity threshold, and therefore the ambient light detection module 310 does not trigger the position indicator lamp 210 to be turned on, but the current time is still within the preset time period, so the time determination module 320 can keep the position indicator lamp 210 on, and the situation that the position indicator lamp 210 is turned off by mistake due to the fact that the vehicle lamp light directly illuminates the user at night when the on-off of the position indicator lamp is controlled by only depending on the ambient brightness is avoided by the time determination module 320.

In some embodiments, the AR display module 100 is a portable AR display device, which is independently installed on a device bracket of the AR smart helmet 10 or integrated on a helmet body of the AR smart helmet 10.

Adopt portable AR display device, can reduce the cost of helmet, and portable AR display device can the person of facilitating the use carry out position adjustment to it, for example when portable AR display device is integrated on the helmet body of AR intelligence helmet 10, the user can carry out position adjustment to portable AR display device, makes things convenient for the user of different head types, and the adaptation scope of helmet is wider, and is mutual more convenient.

Can be provided with the equipment support on the AR intelligence helmet 10, portable AR display device also can install on the equipment support with external mode, portable AR display device can pass through the power of equipment support this moment, signal interface accomplish the power supply and with AR intelligence helmet 10 between the communication, portable AR display device also can adopt the mode of independent power supply to accomplish wireless data link with AR intelligence helmet 10 through wireless modes such as bluetooth and be connected. The AR display module 100 may also be configured with voice interaction recognition and audio playing functions.

In some embodiments, referring to fig. 3, the AR smart helmet 10 further comprises: a navigation module 400 and a turn indicator 220. The navigation module 400 is integrated on the AR smart helmet 10 and may be built into the AR smart helmet 10. Turn to pilot lamp 220 and install in the both sides of AR intelligence helmet 10, for example can install in the both sides of AR intelligence helmet 10 rear side, and both sides respectively set up a turn to pilot lamp 220 to turn to pilot lamp 220 can adopt continuous-flow type bar light module.

The navigation module 400 is configured to identify a turning node from the navigation route and trigger turning on and off of the turn indicator 220 of the corresponding turning direction according to a distance between the current location and the turning node. Specifically, when the AR smart helmet 10 enters the navigation mode, the navigation module 400 identifies all the location points that need to turn from the planned navigation route in combination with the map data, and these location points are referred to as turning nodes. In addition, the navigation module 400 can also track the position of the user, when the user rides or travels to a position closer to a turning node, the navigation module 400 triggers the turning indicator 220 corresponding to the turning direction of the closer turning node to light up, for example, when the navigation module 400 recognizes that the user rides or travels to a position 20 meters away from a left turn, the left turning indicator 220 can be controlled to display a running left arrow, so that when the user forgets to turn on the turning indicator of the driven vehicle, the user can still remind the surrounding vehicle, especially a person in front of the rear vehicle, that the person is about to turn, and if the user rides a bicycle, the user can also remind the person in front of the rear vehicle that the person is about to turn.

In some embodiments, continuing to refer to fig. 3, AR smart helmet 10 further comprises: IMU attitude module 500. IMU pose module 500 is integrated on AR smart helmet 10 and may be built into AR smart helmet 10. The IMU attitude module 500 may include IMU inertial devices and be configured with associated attitude solution routines. IMU pose module 500 is configured to monitor the ride pose and trigger the illumination of turn indicator lights 220 when the ride pose is a laterally inclined pose.

Specifically, when the user is driving forward, if the user is changing lanes, although the lane change does not belong to steering, it is also necessary to prompt the surrounding vehicles, especially the rear vehicle, so when the IMU attitude module 500 determines that the current attitude of the user is a left-inclined attitude or a right-inclined attitude, it indicates that the user is changing lanes, and thus controls the corresponding turn indicator 220 to be turned on, and when the attitude of the user is not inclined laterally, it indicates that the user is not changing lanes or has just changed lanes, and at this time, the turn indicator 220 may be controlled to be turned off. Through discerning user's lane change action, can avoid the user to do not hit the light and directly change the lane equally, and then avoid resulting in the rear vehicle not to judge in advance and take place the accident. Therefore, the riding posture (equivalent to a driving posture) of the user is monitored through the IMU posture module 500, and relevant interaction is completed according to the corresponding posture. For a user driving an electric bicycle, the IMU attitude module 500 can also monitor the driving attitude of the user and complete corresponding interaction.

It should be noted that the criterion for determining whether the current driving posture of the user belongs to the lateral tilt posture may be determined by a lateral tilt threshold, and if the inclination exceeds the lateral tilt threshold, the current driving posture is considered to belong to the lateral tilt posture, otherwise the current driving posture does not belong to the lateral tilt posture. And, the bicycle also has lane-changing behavior, e.g. at the crossroad, the red light in front prohibits straight going, the user

In addition, the IMU attitude module 500 can also provide relevant azimuth and acceleration indexes required by inertial navigation for the driving navigation of the user, and both the navigation information and the riding attitude information (driving attitude information) displayed to the user by the AR display module 100 are provided by the IMU attitude module 500.

In some embodiments, the IMU pose module 500 is further configured to acquire an acceleration change condition in the moving direction, and trigger the blinking of the turn indicator light 220 and the position indicator light 210 when the acceleration change condition satisfies a set condition. Wherein the setting conditions include: the acceleration change degree is higher than the preset degree value.

Specifically, ride forward or the in-process of traveling suddenly brake when the user, then the acceleration variation in user unit interval is great to the acceleration variation has exceeded the change threshold value, IMU gesture module 500 can detect that the user has taken place great change suddenly at the acceleration of riding direction or the direction of traveling this moment, and then the indicator 220 that turns to of control both sides is with the same frequency scintillation, still controls the highlight scintillation of position warning light 210 simultaneously to warn the rear vehicle, remind the rear vehicle to notice the brake and avoid knocking into the back.

For the position indicator light 210 and the turn indicator light 220, after the flashing is triggered, the flashing priority is higher than the flashing priority, if the position indicator light 210 is originally in a normally-on state, the position indicator light 210 will flash when the flashing is triggered, and when the flashing is finished, the normally-on state will be recovered or turned off according to whether the ambient light detection module 310 and the time determination module 320 are triggered. The same applies to the turn signal lamp 220.

Referring to fig. 4, one specific determination process for turning on the turn signal lamp 220 may be: after navigation is started, sequentially judging whether a left steering node is about to be reached or not, whether a right steering node is about to be reached or not and whether the acceleration reduction amount exceeds a change threshold or not, and if the judgment results are negative, restarting sequential judgment; if one of the judgment results is yes, the corresponding steering indicator lamp is lightened or flickers at the same frequency, and the position indicator lamp is also lightened and flickered while the steering indicator lamp flickers at the same frequency; if the user is about to turn to the vehicle and brakes suddenly, the same-frequency flickering is preferentially carried out.

Highly integrated through AR intelligence helmet 10 with AR demonstration, interaction, pronunciation, gesture analysis, navigation, camera, intelligent light early warning etc. through the integration and the interaction of multisensor, realize intelligent navigation, intelligent indicator, the mutual integration solution of intelligent pronunciation.

In some embodiments, referring to fig. 3, the AR smart helmet 10 further comprises: a camera module 600 and a first button 710. The camera module 600 is installed on the AR intelligent helmet 10, specifically, the camera module 600 can be installed right in front of the forehead of the AR intelligent helmet 10, the camera module 600 is used for shooting video images in front of a user, real-time video recording can be performed in the riding or driving process of the user, the whole riding or driving process is recorded, when the user bumps and falls down, the camera module 600 can automatically upload video images from a certain time before to a certain time after the event occurrence time to a cloud server, for example, the user crashes at the time of T1, the camera module 600 uploads video images in the time period of [ T1-10min, T1+10min ], so as to record accidents and determine responsibility.

First button 710 can set up on the surface of AR intelligence helmet 10 to be located the convenient position that reaches and operate of user, the user can trigger camera module 600 to shoot through pressing first button 710, so that upload the image of shooing to the server. The difference between the camera triggering function of the first button 710 and the automatic video recording function of the camera module 600 is that the automatic video recording of the camera module 600 occurs during riding or driving, and the first button 710 can be manually operated by a user when the user stops or does not ride or drive, for example, when the user is delivering a take-out product, the shooting function required when the user manually triggers the first button 710 to complete taking and taking an order, providing a flow monitoring and archiving function of images for the take-out product delivery, and the user is not driving.

In some embodiments, continuing to refer to fig. 3, AR smart helmet 10 further comprises: a second button 720. The second button 720 may also be disposed on the outer surface of the AR smart helmet 10 and spaced a distance from the first button 710 to avoid user confusion, false presses, and false touches. The second button 720 triggers the camera module 600 to shoot when pressed down equally, but the shooting that the second button 720 triggers is the volume that is used for making the operation module of high in the clouds server or AR intelligent helmet 10 discernment testee and benchmark object from the image of shooing to obtain the testee according to the volume of benchmark object. Therefore, the contents of the commands issued after the first button 710 and the second button 720 are pressed are different. For example, when the user is delivering take away, the take away box and the transported object placed in the same image can be photographed and identified by manually triggering the second button 720, and the volume of the transported object can be estimated by calibrating the image of the standard take away box whose volume is known.

It is understood that the first button 710 and the second button 720 may be provided as the same button, and whether to perform the function of the first button 710 or the function of the second button 720 is distinguished by the duration of pressing. For example, when pressing down duration and not exceeding 1 second, trigger camera module 600 and shoot and upload the server, when pressing down duration and exceeding 1 second, trigger camera module 600 and shoot and carry out the measured object volume estimation. Further, the first button 710 and the second button 720 may be provided as the same knob, and whether to perform the function of the first button 710 or the function of the second button 720 is distinguished by the difference of the rotational positions.

In some embodiments, continuing to refer to fig. 3, AR smart helmet 10 further comprises: wear detection module 810. Wear and detect module 810 and integrate on AR intelligence helmet 10 to can place in AR intelligence helmet 10. Wear to detect module 810 and include multiple sensor, be the comprehensive intelligent detection module who has assembleed multiple sensor, these sensors all are used for detecting whether AR intelligent helmet 10 is in wearing the state. And wear detection module 810 and be configured as the testing result according to this multiple sensor and judge whether AR intelligence helmet is in wearing the state to trigger the circular telegram of AR intelligence helmet and start when judging that AR intelligence helmet is in wearing the state.

In some embodiments, the wear detection module 810 may include more than one or even all of a distance measurement sensor, a body charge sensing sensor, a light intensity sensor, and a pressure sensor, all mounted on the inner side of the helmet. The distance measuring sensor can adopt an infrared distance measuring sensor and is used for detecting the distance of the inner side of the helmet; the human body charge induction sensor is used for detecting the charge on the inner side of the helmet; the light intensity sensor is used for detecting the brightness of the inner side of the helmet; the pressure sensor is used for detecting the stress condition of the inner side of the helmet. In this embodiment, the wearing detection module 810 includes all kinds of the above sensors as an example.

The judgment strategy of wearing the detection module 810 may be that only when the judgment results of all the sensor detection results all represent that the AR intelligent helmet is in a wearing state, the power-on start of the AR intelligent helmet 10 is triggered. That is to say, only when the detection result of all sensors all represents that AR intelligent helmet 10 is worn, wear detection module 810 and can judge that AR intelligent helmet 10 is worn, if the detection result of one or more of the sensors all represents that AR intelligent helmet 10 is not worn, then the sensors that give the detection result that representation AR intelligent helmet 10 is worn may have taken place the false positive, so just lead to the detection result of each sensor different, can not judge that AR intelligent helmet 10 is worn this moment.

The wear detection module 810 can turn on the determination of whether the user wears the helmet once every 500 ms. When determining whether the wearing detection module 810 is worn, the wearing detection module may determine whether the wearing detection module is worn by comparing the detection results of the sensors with corresponding set values, and the detection results of the sensors may be sequentially compared in a set order. In some embodiments, the order of determining the sensor detection results adopted by the wearing detection module 810 when determining the wearing state is: distance measuring sensor, human body charge induction sensor, light intensity sensor and pressure sensor.

Specifically referring to fig. 5, the wearing detection module 810 first obtains a detection value of the infrared distance measurement sensor, if the infrared distance measurement detection value is smaller than a first set value, it indicates that an object enters the helmet, and at this time, the next sensor continues to determine, otherwise, the infrared distance measurement detection value is determined again.

When the infrared ranging detection value is smaller than the first set value, the wearing detection module 810 acquires the detection value of the human body charge induction sensor, if the human body charge detection value is effective, it is a component of a human body that the human body enters the helmet, at the moment, the judgment of the next sensor is continued, and otherwise, the judgment of the infrared ranging detection value is carried out again.

When the human body charge detection value is effective, the wearing detection module 810 acquires the brightness detection value of the light intensity sensor, if the brightness detection value is smaller than a second set value, the occupied space of the human body part in the helmet is larger, and the human body part is more consistent with the shape of the cavity on the inner side of the helmet, the judgment of the next sensor is continued, and if not, the judgment of the infrared distance measurement detection value is carried out again.

When the brightness detection value is smaller than the second set value, the wearing detection module 810 obtains the pressure detection value of the pressure sensor, if the pressure detection value is smaller than the second set value, it is indicated that the human body part in the helmet touches the corresponding pressure point, and it is indicated that the human body part in the helmet is the head of a human body, at this time, the starting of the helmet starting process is triggered, the control main board 820 and the power supply system 830 are started, the peripheral function module is powered on, the control main board 820 completes the starting self-check of the function module, otherwise, the judgment of the infrared distance measurement detection value is carried out again.
