Description

Technical Field

[0001] The present disclosure generally relates to the field of amusement parks. Specifically, embodiments of the present disclosure measure guests in an amusement park to evaluate one or more physical characteristics and / or determine eligibility to enter an attraction in the amusement park, such as eligibility to enter an entertainment ride as a passenger. The present disclosure relates to methods and facilities utilized for such determination.

Background Art

[0002] Theme parks or amusement parks are becoming increasingly popular. More sophisticated and innovative ride attractions have helped increase the popularity and success of such parks. Some attractions have height restrictions for passengers who exceed a height threshold. For example, a theme park ride attraction can involve a vehicle such as a roller coaster type vehicle or other vehicle that moves along a ride path. The height restriction of the ride limits the ride to passengers within a specific height range that can fit into the restraint of each seat. Before entering the ride, passengers can be measured to determine if they fit within the height restriction. For example, a passenger can manually compare their height to a line written on a wall.

Mode for Carrying Out the Invention

[0016] Embodiments of the present disclosure facilitate attraction measurement techniques that measure one or more guest characteristics and further use these to determine the eligibility of guests to enter attractions with height restrictions. These measurement techniques enable the measurement of guests in various postures such as standing, sitting, bending, or crouching postures. Further, these measurement techniques reduce user measurement errors or confusion related to attraction eligibility requirements.

[0017] FIG. 1 shows an example guest measurement system 12 including a controller 14 coupled to one or more cameras 16 that generate image data in an attraction guest measurement area 20. And the image data is used to generate guest measurement values by mapping the image data of the virtual world into the real-world space so as to estimate guest measurement values using the relative virtual distances between anatomical features within the image data.

[0018] One or more cameras 16 for capturing image data are coupled to or housed within the guest measurement device 24. The guest measurement device 24 is a portable handheld device that includes one or more cameras 16 for obtaining measurement values by moving the handheld device in front of the guest to acquire relevant data. In one embodiment, the guest measurement device 24 that includes one or more cameras 16 is a handheld mobile device or a tablet. In certain embodiments, the guest measurement device 24 can be coupled to a kiosk or a fixed-position housing.

[0019] One or more cameras 16 can also obtain image data used to map a virtual space into the real world, including reference markers 32 arranged along an axis of a plane within the measurement area 20. In the illustrated example, the reference markers are arranged on a wall or support 34 positioned at an appropriate location within the measurement area 20 such that the guest comes to an appropriate position intersecting the plane of the reference markers 32. The guest measurement system 12 can include position markers 38 for properly positioning the guest relative to the reference markers 32. When the guest measurement device 24 is portable or at least partially adjustable, it can be oriented or repositioned to capture both the guest and the reference markers 32 within the field of view of the camera 16.

[0020] The reference markers 32 can be QR codes, images (e.g., 2D images), printed or formed shapes, or other image-resolvable features of a fixed size or fixed dimensions. Based on the relationship between the features of the reference markers 32 in the image data and the known real-world measurements of the features of the reference markers 32, the anatomical features of the guest can be mapped from the virtual space to the real-world space.

[0021] The camera 16 or more above collects image data including image data representing one or more guests shown as the first guest 22a and the second guest 22b in FIG. 1. The image data is provided to the controller 14, and the controller 14 uses the image data to determine guest characteristics such as height. The guest measurement system 12 can accurately measure the guest while the guest is hunched over or sitting in a wheelchair or stroller. As shown by way of example, the first guest 22a is taller than the second guest 22b. However, while the first guest 22a is hunched over, the second guest 22b is holding a balloon. If the distance 30 from the ground represents the minimum height to ride the attraction, in an optical beam type sensor that measures the interruption of the beam at the lowest height, the balloon will cause the beam to be interrupted and the height of the second guest 22b will be erroneously shown to be sufficient. Further, the first guest 22a will also be erroneously identified as not having sufficient height. In contrast, the measurement system 12 of the present disclosure shown herein correctly identifies that the height of the first guest 22a is sufficient and correctly identifies that the height of the second guest 22b does not reach at least the minimum height. The system 12 uses sensor signals to identify anatomical features and generates a height calculation based on the estimated dimensions or distances between the anatomical features. In an embodiment, the system 12 can provide a display or other indicator indicating a qualified or unqualified height calculation.

[0022] In one embodiment, one or more guest characteristics are identified using information obtained via one or more cameras 16. Based on these, FIG. 2 is a flowchart of a method 100 of using a guest measurement system according to the present technology. Method 100 includes receiving image data indicating guest characteristics from one or more cameras 16 disposed within a measurement area 20 (block 102). In one embodiment, the measurement area 20 can be present at an amusement park entrance, a guest service center, or an individual attraction. In one embodiment, a guest measurement event can be performed once, and the system 12 stores the determined guest measurement value and provides this guest measurement value for validation at different attractions. Thus, the guest 22 only needs to be measured once for various attractions.

[0023] Method 100 includes detecting anatomical features based on, for example, one or the image data (block 104). It can be understood that the image data can first be filtered, normalized, calibrated, and / or preprocessed so as to be easily used with the height calculation logic as shown herein. Based on the image data, the presence and position of various limbs and / or anatomical features of the guest, including the guest's head, neck, torso, pelvis, thighs, knees, calves, shins, ankles, feet, toes, hands, wrists, fingers, elbows, forearms, etc., can be identified or detected. The image data also includes reference markers 32, and method 100 also identifies the reference markers 32 within the image. The reference markers 32 can be selected so as to be quickly and easily identified and distinguished from other real-world features captured in the image data. In one embodiment, the reference markers 32 can be imaged in the visible spectrum and / or outside the visible spectrum. Thus, the image data can include data from a visible light camera (e.g., an RGB camera) and a fluorescence or infrared camera.

[0024] Using the fiducial marker 32 as generally described herein, scale the distance between one or more different identified anatomical features from virtual space to real-world space (block 106). In certain embodiments, these techniques can be used to identify limb differences such as amputations and the lengths of identified amputations. Based on the stored attraction information, notifications can be generated for one or more attractions in the amusement park for which the guest meets the ride conditions.

[0025] Method 100 includes generating a guest height calculation based on the scaled distance (block 108). The estimated dimensions can include length estimates between joints (e.g., from wrist to elbow, from elbow to shoulder, from ankle to knee, from knee to hip), and / or width estimates in a plane parallel to the length axis. By measuring a guest using the methods described herein, it can be determined whether a guest can enter a vehicle without having to get up from a wheelchair, mobility aid, stroller, etc. Further, it will be understood that the techniques described herein are also applicable to guests without mobility restrictions.

[0026] Guest features can be anatomical features, for example, each limb of the guest is identified. It is possible to identify the guest's head, neck, torso, pelvis, arms, knees, thighs, ankles, feet, hands, toes and fingers, etc. It can be understood that some of these limbs can have paired or corresponding limbs (i.e., right and left limbs) that cross the medial axis of the guest's body. Embodiments of the present disclosure include identifying the virtual spatial distances between the identified anatomical features and scaling these measurements to the real world. The total height of the guest can be estimated or calculated using the remembered relationship between height and these distances. In certain embodiments, the scaled distances from the top of the shoulder to the top of the head, from the top of the shoulder to the waist, and / or from the waist to the floor or feet can be used to determine the height of the guest. Embodiments of the present disclosure include generating a calculation of the guest's total height based on scaling the identified distances in the image data (e.g., virtual space) using the features of the reference marker 32 as a magnification factor to the real world space. In this way, the guest can remain seated (e.g., in a wheelchair) while being measured prior to access to the vehicle.

[0027] FIG. 3 is an example user interface 130 of the guest measurement system 12 showing a camera feed 132 displayed via the user interface 130. The user interface 130 can include a box or other marker 136 overlaid on the camera feed 132 indicating the position of the appropriate reference marker 32. In some embodiments, an operator can open a guest measurement application operating on a handheld device and activate the camera. The camera captures the displayed real-time camera feed 132. In some embodiments, the user interface 130 also includes clickable keys 138. In some embodiments, the clickable keys 138 are inactive by default and activate only when a reference marker 32 is positioned at a location suitable for triggering the display of the clickable keys 138 on the user interface 130 or at a location suitable for triggering the activation of the clickable keys 138. In some embodiments, in addition to or instead of this, the user interface 130 can also include overlay markers that guide the positioning of the guest to an appropriate position within the camera feed 132 relative to the reference marker 32. Once the operator determines that the guest is properly positioned, the operator can provide user input via the clickable keys to capture image data such as a still image for use in guest height calculation as described herein. In some embodiments, the captured still image does not include markers overlaid on the user interface 130.

[0028] Figure 4 shows the captured still image 138 used for calculating the height of the guest, which is displayed on the user interface 130. Therefore, the user interface 130 in FIG. 3 can transition to the user interface 130 in FIG. 4 during operation. After the image data is captured, the system 12 uses the image data of the captured still image 139 to generate one or more anatomical feature markers 140 that are overlaid and displayed on the captured still image 138. The anatomical feature markers are generated based on anatomical feature recognition performed on the image data. For example, the system 12 can use a trained neural network to identify one or more of the head, eyes, mouth, nose, eyebrows, shoulders, hands, feet, waist, hands, feet, etc. The guest measurement area 20 can be maintained with a white or plain surrounding background so that the captured still image 138 does not contain other features that can cause false positives. Therefore, in an embodiment, the captured still image 138 can include only the reference marker 32 and the guest 22 as objects in the image, thereby improving the computational efficiency of anatomical feature recognition.

[0029] In one embodiment, the system 12 completes the first anatomical feature recognition using the captured still image. In the illustrated embodiment, the user interface 130 includes three different anatomical feature markers 140: the top-of-head marker 140a, the shoulder marker 140b, and the waist marker 140c. The anatomical feature markers 140 are overlaid and displayed at positions corresponding to the respective identified anatomical features on the captured still image 138. In the illustrated embodiment, the anatomical feature markers 140 are lines with text labels that intersect or extend beyond the corresponding identified anatomical features. However, it should be understood that other graphic indicators, shapes, or configurations are also envisioned. For example, the identified anatomical features can also be marked by highlighting, shading, boxing, etc.

[0030] System 12 can permit operator input to confirm that the anatomical feature markers 140 are correctly positioned before proceeding with the calculation of the guest's height based on these identified anatomical features, in order to account for variations in the guest's clothing, hat, hairstyle, and posture. In the illustrated example, the anatomical feature markers 140 appear to generally correspond to the correct positions, and thus the user can click or activate the confirmation key 142. On the other hand, if one or more of the anatomical feature markers 140 are not correctly positioned, the user can click the edit key 144 to manually change the position of one or more of the anatomical feature markers 140.

[0031] Figure 5 shows an example of the user interface of System 12 where the top-of-head marker 140a is incorrectly positioned at the top of the guest's hat rather than generally corresponding to the top of the guest's head. The operator can click the edit key 144 to permit manual repositioning of the top-of-head marker 140a. The repositioning can respond to various guest inputs such as drag, downward arrow, gesture by hand or gaze, or voice command. Once all of the anatomical feature markers 140 are correctly positioned, the operator can select the confirmation key 142 to instruct System 12 to proceed with the calculation of the guest's height.

[0032] In one embodiment, method 100 can include machine learning features that use a training set of valid measurements. In one example, the training set can generate valid measurements using height measurements from another method. Using another measured height of a particular individual, the system can be trained to adjust the positioning of markers on an image of the individual until the height calculation generated using the markers matches the correct height from another method. In some embodiments, a feature identifier can be trained using a machine learning model to more accurately identify anatomical features and / or the position of markers within an image. Additionally, the machine learning model can include assistive features that help an operator relocate marker 140. That is, the machine learning model can be used to identify whether the operator is providing accurate input for relocating the marker and generate a display indicator indicating that the marker positioning may be inaccurate or that a check can be triggered prior to submission.

[0033] FIG. 6 is a schematic diagram of a measured virtual space distance that can be scaled as shown herein. For example, using identified anatomical features (or in an embodiment, a portion of marker 140 overlaid and displayed), image distances 150, 152 between these identified features can be determined. Additionally, the image dimensions of reference marker 32 can be determined. In the example shown, reference marker 32 generally has a rectangular shape and includes a height dimension 154 and a width dimension 156. Since reference marker 32 is a real-world object with fixed real-world dimensions, the real-world dimensions can be used as a magnification factor to generate real-world values corresponding to distances 150, 152 between the identified anatomical features. In some embodiments, the virtual space can be in arbitrary or relative units. For example, based on virtual dimensions 154, 156, distances 150, 152 can be determined to be relative values. In one example, the distance 152 from the shoulder to the waist can be determined to be three times the height dimension 154. Thus, the magnification factor used to determine the real-world distance from the guest's shoulder to the waist is three.

[0034] In the illustrated example, anatomical features of the head, shoulders, and waist are shown, but more or fewer anatomical features can also be identified. An anatomical model can be used to determine the final total body length calculation based on the real-world scaled distances between these identified anatomical features. Thus, the guest height can be a function of the typical height range of an individual where the distances from shoulder to waist, from shoulder to head, and from waist to head are the same as the measured values. Additionally, system 12 can incorporate feedback and machine learning to improve the guest measurement calculation.

[0035] FIG. 7 is a block diagram of a guest measurement system 200 (e.g., guest measurement system 12) according to this embodiment. The guest measurement system 200 includes a controller 202 that can be implemented in a computer device, a server, a distributed processor, or a cloud computing environment. The controller 202 includes a processor 204 and a memory 206. The processor 204 can include one or more processing devices (processing or computing circuits), and the memory 206 can include one or more tangible non-transitory machine-readable media. As an example, such machine-readable media can be RAM, ROM, EPROM, EEPROM, or optical disk storage, magnetic disk storage, or other magnetic storage devices, or any other medium that can be used to hold or store desired program code in the form of machine-executable instructions or data structures and can be accessed by the processor 204 or other processor-based devices (e.g., mobile devices). The controller 202 can utilize one or more types of software-based instructions executable by the processor 204. For example, these instructions can include accessing stored information such as real-world features of the reference marker 32. Relationships between variables can be found using related techniques. In one embodiment, the system 200 can identify the correct magnification for scaling distances in the image data to the real-world space using relationships between one or more features of the reference marker 32 in the image data.

[0036] System 200 can receive various inputs 210 to generate a guest height indication and perform other actions based on the estimated guest height. For example, system 200 can receive vehicle information 212 that includes height restrictions for a particular vehicle. Vehicle information 212 can include, among other things, the number of available seats, the number of seats that can accommodate guests on an assistive mobility vehicle, restrictions on which types of assistive mobility vehicles are suitable for a particular vehicle, height restrictions, and weight restrictions. For example, a vehicle can have a particular height or weight restriction. Also, a particular vehicle seat may only be able to accommodate passengers of a particular depth, and thus a guest with a particular disability device (e.g., cane, wheelchair, etc.) may not be able to board the vehicle and may require the use of an additional seat (e.g., an adjacent seat) or a particular seat on the vehicle that is suitable for the guest.

[0037] System 200 receives image data from one or more cameras 214. The one or more cameras 214 can include visible light cameras or cameras that detect non-visible light. The one or more cameras 214 can also include infrared cameras and RGB cameras to obtain measurements of the guest.

[0038] System 200 can use various mathematical equations and relationships (e.g., geometric shapes, 3D Pythagorean theorem, linear interpolation) between the virtual space and the real-world space to perform scaling between the virtual space and the real-world space. Controller 202 can perform calibration that scales the measurements obtained by one or more cameras 214 using the measured dimensions of the reference markers to determine the height of the guest. Controller 202 determines the measured guest height calculation 218 using the scaling. Controller 202 outputs the total height calculation while the guest remains seated or is assisted by the guest's assistive equipment (e.g., the guest's wheelchair, mobility aid, stroller) without the guest having to get off the assistive equipment, and determines whether the vehicle has sufficient space to accommodate the guest. In one embodiment, the output can include a notification regarding eligibility to ride a particular attraction based on the estimated height.

[0039] Controller 202 can be communicatively coupled to a display 219 that can display the height calculation 218. In one embodiment, Controller 202 can receive user input 220, for example, via a capacitive sensor incorporated in the display 219. The estimated height of the guest can be output to the display 219 to inform the amusement park staff whether the guest 22 can be accommodated in the vehicle.

[0040] In some embodiments, the disclosed guest measurement system 200 can correlate the guest to the measured height using face recognition or other guest tracking techniques. Thus, the guest can be measured early in the day and the estimated height logged in the guest profile. Guest recognition technology can be used to associate the recognized guest with the estimated height using the guest profile at other attractions to determine ride eligibility. In this way, the measurement only needs to be performed once throughout the day.

[0041] FIG. 8 is a schematic side view of an attraction measurement area of a theme park that utilizes the guest measurement system 200 of FIG. 7 according to this embodiment. In the illustrated embodiment, the guest 22 can be measured in an attraction measurement area 224 that can be adjacent to the vehicle area 226 or can be part of the guest service space so that the guest is measured once as part of the admission process or the like. The attraction measurement area can include one or more cameras 232 within the attraction measurement area 220. One or more sensors 232 can be moved via a motor 234 communicatively coupled to the controller 202 to accurately capture image data. In addition or alternatively, one or more sensors 232 can be disposed within a handheld device 236 (e.g., a cane, a tablet, or a mobile device). A theme park employee 238 can use the handheld device 236 to capture image data when the handheld device 236 is placed in front of the guest 22.

[0042] It will be understood that the guest 22 can be requested to move into the space 240 so that the guest 22 can be measured. The space 240 can include a reference marker 244. The space 240 can be an area that is easily visible via one or more cameras 232 of the handheld device 236 held by a theme park employee. The reference marker 244 can be a specific marker or prop having a resolvable feature that exists within the plane of the space 240. The reference marker 244 can be arranged substantially parallel to the guest measurement space 240. When it is determined that the guest 22 has arrived in place, height measurement can be started. In some embodiments, the height measurement of the guest is started by the capture of the reference marker. That is, the camera 232 picks up the reference marker and activates the guest measurement feature of the system 200.

[0043] In an embodiment, a sensor 232 is housed in a handheld device 236 that can be a mobile device or a tablet, and an operator activates the sensor 232 via interaction with the user interface of the mobile device or tablet. In certain embodiments, features of the controller 200 are also housed within the handheld device 236. In other embodiments, the handheld device 236 communicates wirelessly with the system 200, and image data is communicated to a remote or stand-alone system processor 204 that performs guest height calculations based on the communicated image data. In other embodiments, guest measurements can be performed using one or more fixed-position cameras placed within the kiosk location of the guest measurement area 220.

[0044] It should be understood that the guest measurement system 200 can be used to measure a guest 22 who is on a wheelchair, an assistive mobility device, a stroller, and a cart, or even when the guest 22 is holding an accessory 248 (e.g., a cane, a shopping bag, a wallet) that may partially block the guest's field of view. In the illustrated embodiment, the guest measurement system 200 can be used to measure a guest 22 on a wheelchair. It will be understood that when the guest 22 is on a wheelchair or a stroller, a part of the guest's body may be blocked from the field of view of one or more cameras 232. For example, the field of view of the guest's left foot may be blocked by a component of the wheelchair. In this case, one or more cameras 232 may not be able to accurately capture the dimensions of the guest's left foot. However, as described herein, the operator 238 can provide the position of anatomical features via user input so that the guest height calculation can proceed when the feature information used in the calculation is missing or unresolvable in the image data.

[0045] In an embodiment, depending on the configuration of the vehicle 252, the system 200 can receive an update from the vehicle 252 when the seat configuration is changed or when boarding the vehicle 252. Accordingly, the system 200 can also determine whether the guest height calculation is adapted to the current configuration or boarding state of a particular vehicle 252. For example, if the vehicle 252 includes three seats for passengers under a particular height range, the system 200 can track whether any of these seats are available when a guest within the allowable height range is present for measurement.

[0046] Although only some features of this embodiment have been illustrated and described herein, many modifications and variations will occur to those skilled in the art. Accordingly, it is to be understood that the appended claims are intended to cover all such modifications and variations as fall within the true spirit of the present disclosure. Further, it is to be understood that some elements of the disclosed embodiments can be combined with, or substituted for, one another.
