Description

Technical Field

[0001] The present disclosure relates to a technical field related to augmented reality, and more specifically to a construction method based on augmented reality. Background Art

[0002] In the existing technology, augmented reality (AR) technology integrates the virtual environment generated by the computer with the real environment around the user by means of optoelectronic display technology, interactive technology, multiple sensor technologies, and computer graphics and multimedia technology, so that the user can be convinced from the sensory effect that the virtual environment is a part of the real environment around him. Augmented reality has the new characteristics of combining virtuality and reality, real-time interaction, and three-dimensional registration.

[0003] During the construction process, navigation can be carried out through augmented reality technology, that is, obtaining drawings in advance and guiding construction through AR. However, the accuracy of AR-guided construction is not enough, which will cause certain errors (for example, the AR method indicates that you should go 5 meters from point A to point B, but the actual distance between points A and B may be more than 5 meters or less than 5 meters, for example, you have actually moved forward 5.05 meters. This will not only cause the construction accuracy to fail to meet the requirements, but also cause the composite scene generated by AR technology to be distorted. Summary of the invention

[0027] As mentioned above, the following technical problems exist in the prior art, namely, the traditional navigation or display technology based on augmented reality AR technology has the technical defect of being not accurate enough. In order to solve the technical problems existing in the prior art, the inventor of the present disclosure innovatively thought of communicating and optimizing the AR device and the distance measuring device based on augmented reality AR technology, and then calibrating the projection of the target object in the real scene based on the measurement data and the design data of the corresponding target object, so as to achieve the optimization of the composite AR image, and make the construction more accurate. In summary, the inventor of the present disclosure innovatively proposed a construction method based on augmented reality, the construction method comprising: establishing a communication connection between the augmented reality device and the distance measuring device; obtaining the construction drawings of the target object; projecting the construction trajectory map associated with the construction drawings into the scene where the target object is located via the augmented reality device; measuring the target object along the projection route by the distance measuring device to obtain the measurement data of the target object; and calibrating the projection of the target object in the scene based on the measurement data and the design data of the target object. In this way, the construction method based on augmented reality disclosed in the present disclosure can establish a communication connection between the augmented reality device and the distance measuring device, and then calibrate the projection of the target object in the scene based on the measurement data and the design data of the target object, so that the distance measuring device can be used to further enhance the ability to optimize the composite AR image under the augmented reality AR technology, and the construction will be more accurate. In other words, in layman's terms, the construction method based on augmented reality according to the present disclosure will first obtain the drawings, which can be either ready-made or measured on-site as needed. Then, the construction method based on augmented reality according to the present disclosure performs projection navigation and trajectory guidance through the augmented reality AR device. The user of the augmented reality AR device can, for example, obtain accurate measurement data and trajectory information by using or carrying a distance measuring device to walk along the navigation trajectory, and obtain the deviation data between the data measured by the distance measuring device and the AR device, and calibrate the projection of the target object in the scene based on the deviation data. In addition, preferably, the augmented reality-based construction method according to the contents of the present disclosure can introduce an autonomous learning model, which can learn deviation data and train the model, and compensate the image in AR with the deviation data output by the model, so that the image in AR has as small an error as possible or even no error.

[0028] The following will be combined Figure 1 and Figure 2 To describe the construction method based on augmented reality disclosed in the present disclosure. Figure 1FIG. 1 shows a connection diagram of a construction method 100 based on augmented reality according to an embodiment of the present disclosure, and FIG. Figure 2 A system block diagram of a hardware device for a construction method based on augmented reality according to an embodiment of the present disclosure is shown.

[0029] from Figure 1It can be seen that the construction method 100 based on augmented reality according to the present disclosure includes at least the following five steps, namely: first, in method step 110, a communication connection 230 is established between the augmented reality device 210 and the distance measuring device 220. Here, the augmented reality device can be head-mounted glasses, a wearable device with a display, a smart watch or even a smart projector, etc.; the distance measuring device 220 can be a distance measuring wheel, or other distance measuring devices based on laser technology such as a level and a projection meter; and the communication connection 230 can be a network connection based on a WiFi protocol, or a network connection based on other bus protocols such as RJ45, ZigBee, Bluetooth, ProfiBus, etc., as long as the communication connection between the augmented reality device 210 and the distance measuring device 220 can be achieved. Then, the construction method 100 based on augmented reality according to the content of the present disclosure includes method step 120, in which the construction drawing of the target object is obtained, that is, what kind of construction process needs to be carried out, for example, to carry out the parking space line drawing operation, then it is necessary to obtain a parking lot parking space planning drawing, which includes, for example, the area data of the parking lot, the number of planned parking spaces, and the specific coordinate position information of each parking space. Next, the construction method 100 based on augmented reality according to the content of the present disclosure includes method step 130, in which the construction trajectory map associated with the construction drawing is projected into the scene where the target object is located via the augmented reality device 210, that is, for example, when the display of the augmented reality device 210 such as a smart wearable device, the user can see the real scene superimposed with the object that needs to be constructed, such as showing the parking space lines that have not yet been marked in an empty parking lot. Next, the construction method 100 based on augmented reality according to the present disclosure includes method step 140, in which the target object (e.g., the planned parking space) is measured along the projection route by the distance measuring device 220 to obtain the measurement data of the target object (e.g., the planned parking space); and in method step 150, the projection of the target object in the scene is calibrated based on the measurement data and the design data of the target object (e.g., the planned parking space). For example, the standard parking space usually has a length of 5.3 meters and a width of 2.5 meters, but the projection of the parking space based on AR technology is not necessarily exactly 5.3 meters * 2.5 meters in size. At this time, the projected parking space line can be measured with the help of a distance measuring device such as a distance measuring wheel. If the actual size measured is 5.83 meters * 2.75 meters, it needs to be scaled to obtain a more accurate size, and in actual construction, it is necessary to perform construction according to the calibrated projection to improve construction accuracy.In this way, the augmented reality-based construction method 100 disclosed in the present disclosure can establish a communication connection 230 between the augmented reality device 210 and the ranging device 220, and then calibrate the projection of the target object in the scene based on the measurement data and the design data of the target object (such as a parking space), thereby making it possible to use the ranging device 220 to further enhance the ability to optimize the composite AR image under the augmented reality AR technology, and make the construction more accurate.

[0030] After this calibration process is carried out several times, the subsequent construction process in the same construction scene will be able to obtain a more accurate projection. For example, after the size of the AR projection is calibrated using augmented reality technology, if the parking space is measured or the construction of the parking space is provided based on the calibrated projection, a parking space that is basically consistent with or completely consistent with the design size can be obtained. For example, 10 parking spaces are planned, the AR projection is calibrated according to the first few parking spaces (for example, three parking spaces), and the calibrated AR projection is used for navigation, and the lateral data measured subsequently will be more accurate.

[0031] Preferably, in the technical solution according to the present disclosure, the construction method 100 further includes ( Figure 1 (not shown): obtaining dimensional data associated with a predetermined construction trajectory map; and marking the construction trajectory map based on the dimensional data with the aid of a distance measuring device. For example, if there is a speed bump one meter in front of the first parking space, the position of the speed bump can be marked one meter in front of the first parking space with the aid of a distance measuring device, and the length can also be marked according to the designed length of the speed bump, for example, three meters long and 30 centimeters wide. In this way, the dimensional data associated with the construction trajectory map can be marked, thereby realizing the use of a distance measuring device to further enhance the ability to optimize composite AR images under augmented reality AR technology, and making construction more accurate.

[0032] Furthermore, in the technical solution according to the present disclosure, the construction method 100 also includes ( Figure 1(not shown): based on the measurement data of the ranging device 220, an actual trajectory diagram associated with the real scene is drawn. That is to say, in the technical solution proposed according to the contents of the present disclosure, the actual trajectory diagram of the ranging device 220 can be generated based on the measurement data of the ranging device 220, and data guarantee is provided for optimizing the AR display accuracy of the augmented reality device with the help of the actual trajectory diagram. For example, the size of a parking space projected purely using augmented reality technology may be 5.83 meters * 2.75 meters, so the shape of the displayed parking space is definitely deviated from the actual shape. While under construction, the actual size is controlled with the help of the ranging device 220, and a parking space with an actual size consistent with the design size is drawn. At this time, the shape of the parking space drawn according to the trajectory of the ranging device 220 is more accurately displayed in the augmented reality device 210.

[0033] In the technical solution according to the content of the present disclosure, the construction trajectory diagram includes a predetermined identification point, and the construction method further includes: sending a reminder signal when the distance measuring device approaches or reaches the position of the identification point. In this way, the construction method proposed according to the content of the present disclosure can more advantageously send a reminder signal when the distance measuring device approaches or reaches the position of the identification point, so as to make the construction personnel pay attention to the corresponding identification point to increase the construction accuracy. For example, the construction trajectory diagram may include a wall 0.5 meters away from the end of the first parking space. At this time, when the distance measuring device 220 or the augmented reality device 210 approaches the position, that is, when it approaches the wall, a reminder signal can be sent to ensure the safety of the construction personnel. In other words, the parking area identification needs to be marked on the left column of the first parking space or the index number of the parking space needs to be marked in the middle position of the front end of the first parking space, such as parking space 0001. At this time, a reminder signal can be sent when the distance measuring device 220 or the augmented reality device 210 reaches or approaches the identification point, so that the construction personnel can accurately carry out the construction.

[0034] Preferably, in the technical solution according to the contents of the present disclosure, the construction method further includes: marking when the distance measuring device approaches or reaches the position of the identification point. In this way, the construction method proposed according to the contents of the present disclosure can more advantageously not only send out a reminder signal but also mark the corresponding identification point position when the distance measuring device approaches or reaches the position of the identification point, so as to make the construction personnel pay attention to the corresponding identification point to increase the construction accuracy. As mentioned above, the parking area logo needs to be marked on the left pillar of the first parking space or the index number of the parking space needs to be marked in the middle position at the front end of the first parking space, such as parking space No. 0001. At this time, a reminder signal can be sent when the distance measuring device 220 or the augmented reality device 210 reaches or approaches the identification point, so that the construction personnel can accurately carry out the construction. Specifically, for example, when drawing the front parking line of the first parking space, if the parking line is 2.5 meters long, then the middle 0.5 meters can be reserved for use as a parking space index number mark. At this time, after drawing 1 meter of parking lines on both sides, the construction workers are reminded that they need to draw the parking index number, and they can mark it when they reach the 1 meter position.

[0035] Preferably, in the technical solution according to the present disclosure, the reminder signal includes a visual or auditory reminder signal. In this way, the construction method 100 proposed according to the present disclosure can more advantageously send out a reminder signal when the distance measuring device approaches or reaches the position of the marking point, so as to make the construction personnel pay attention to the corresponding marking point to increase the construction accuracy. In other words, such a reminder signal can be a flashing reminder light, the sound of a beeper, or a voice reminder with corresponding content, or it can be, for example, a text reminder displayed on a display screen or even a vibration reminder function of the distance measuring device 220.

[0036] In the technical solution according to the present disclosure, the construction trajectory map includes predetermined identification points, and the measurement method 100 also includes ( Figure 1(not shown): the identification point is presented in the real scene through the augmented reality device 210. In this way, the construction method 100 based on augmented reality disclosed in the present disclosure can present the identification point in the real scene, so that the construction personnel can intuitively observe the position of the identification point, thereby improving the construction accuracy. As mentioned above, the parking area identification needs to be marked on the left pillar of the first parking space or the index number of the parking space needs to be marked in the middle position of the front end of the first parking space, such as parking space No. 0001. At this time, the identification point can be presented in the real scene based on augmented reality technology before the ranging device 220 or the augmented reality device 210 reaches or approaches the identification point, so that the construction personnel can have an intuitive feeling and avoid misoperation. When the identification point is about to be reached, a reminder signal is issued so that the construction personnel can accurately perform the construction. Specifically, for example, when drawing the front parking line of the first parking space, if the parking line is 2.5 meters long, then the middle 0.5 meters can be reserved for use as a parking space index number mark. At this time, before drawing the 1-meter parking lines on both sides, the identification point is marked with the help of augmented reality technology to remind the construction workers that they need to draw the parking index number. At this time, the parking space index number can be drawn when the 1-meter position is reached.

[0037] Preferably, in the technical solution according to the present disclosure, the construction method 100 further includes ( Figure 1 (not shown): obtaining an update to the construction trajectory map; and modifying the construction trajectory map based on the update. In this way, during the construction process, the construction method disclosed in accordance with the contents of this disclosure can update the construction trajectory map in real time, so that the construction trajectory map can be dynamically modified based on the latest information to obtain the latest and most accurate construction information, thereby providing a guarantee for the construction accuracy of the construction method according to the contents of this disclosure. For example, during the construction process, the designer may find that the original design has design defects, such as there is a column somewhere in the parking lot, and the design of the parking space here obviously cannot meet the parking demand, then the designer can update the construction trajectory map in time, and the construction method based on augmented reality according to the contents of this disclosure can update the construction trajectory map in time, so as to carry out construction with the latest construction trajectory map to ensure construction accuracy.

[0038] Preferably, in the technical solution according to the present disclosure, the construction trajectory diagram is a two-dimensional or three-dimensional diagram of a computer-aided design diagram. In this way, the construction method according to the present disclosure can perform construction planning based on the two-dimensional or three-dimensional diagram generated by computer-aided design such as CAD, thereby improving the application scenario of the construction method according to the present disclosure and improving the construction accuracy of the construction method according to the present disclosure.

[0039] In the technical solution according to the content of the present disclosure, the construction method also includes: training the autonomous learning model 211 based on the measurement data and the design data; and optimizing the projection of the target object in the scene based on the trained autonomous learning model 211. The autonomous learning model here can be one of the mature large models, or it can be configured by the construction personnel according to their own needs. In the actual use process, the autonomous learning model 211 can be trained twice according to the actual information of the construction, so that the trained autonomous learning model 211 is closer to the actual application scene. In this way, the construction method according to the content of the present disclosure can introduce the autonomous learning model 211, so that the autonomous learning model 211 can be trained based on the measurement data and the design data, and the projection of the target object in the scene can be optimized based on the trained autonomous learning model 211, so that the autonomous learning model 211 can be trained based on multiple data, and the images including real scenes and virtual scenes based on augmented reality AR technology can be optimized based on the trained autonomous learning model 211 to improve the display effect and display accuracy.

[0040] To sum up, in the technical solution according to the contents of the present disclosure, the construction method based on augmented reality disclosed in the present disclosure can establish a communication connection between the augmented reality device and the ranging device, and then calibrate the projection of the target object in the scene based on the measurement data and the design data of the target object, so as to realize the ability of optimizing the composite AR image by using the ranging device under the augmented reality AR technology, and make the construction more accurate.
