Example embodiments generally relate to measuring tape devices, and particularly relate to automated measuring tape technologies.
Measuring tapes are common tools used in numerous contexts to obtain linear measurements. While ergonomic and other physical improvements to measuring tapes have been achieved over the years, the same workflow with respect to measuring tapes continues to be used. In short, that workflow is to measure with the tape, mark a measurement, and record the measurement on a notepad or drawing. It is clear that improvements in this area of technology would be beneficial.
An example distance measuring apparatus is provided. The example apparatus may comprise a measuring tape with distance measurement indicia, a camera, and processing circuitry. The processing circuitry may be configured to cause the camera to capture an image of the measuring tape and determine a measurement by analyzing the captured image. The measurement being determined may be based on the distance measurement indicia of the measuring tape within the image at a measurement position. The processing circuitry may be further configured to store the measurement in a memory device.
Another example distance measuring apparatus may comprise a housing having an aperture, a reel assembly, and a measuring tape having a first end configured to extend from the housing through the aperture and a second end configured to be wound on the reel assembly. The measuring tape may have distance measurement indicia. The example apparatus may further comprise a touch control. The touch control may be configured to send a signal to have a camera capture an image of the distance measurement indicia at a measurement position.
An example method is also provided. The example method may comprise causing the camera to capture an image of a measuring tape. The measuring tape may have distance measurement indicia. The example method may further comprise determining a measurement by analyzing the captured image. The measurement may be determined based on the distance measurement indicia of the measuring tape within the image at a measurement position. The example method may further comprise storing the measurement in a memory device.
Having thus described some example embodiments in general terms, reference will now be made to the accompanying drawings, which are not necessarily drawn to scale, and wherein:
Some example embodiments now will be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all example embodiments are shown. Indeed, the examples described and pictured herein should not be construed as being limiting as to the scope, applicability or configuration of the present disclosure. Rather, these example embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like reference numerals refer to like elements throughout. Furthermore, as used herein, the term “or” is to be interpreted as a logical operator that results in true whenever one or more of its operands are true. As used herein, operable coupling should be understood to relate to direct or indirect connection that, in either case, enables functional interconnection of components that are operably coupled to each other.
As indicated above, some example embodiments relate to the provision of a measuring tape device that may have improved measurement workflow capabilities. Such improved measurement workflow capabilities may be accomplished by employing image capturing and image analysis technology in relation to tape measures.
Referring now to
The tape 140 may have an end hook 170 disposed at one end thereof, and may be affixed to the reel assembly 120 at the other end of the tape 140. The end hook 170 may be affixed (temporarily) to an anchor point on a medium that is to be measured. When the end hook 170 is affixed to the anchor point, the tape 140 may be paid out of the aperture 150 and unwound or rolled out from the reel assembly 120. When a desired length of the tape 140 has been rolled out, the user can make any necessary markings, readings, etc., associated with distance measurement indicia that may be printed on the tape 140. The distance measurement indicia generally indicate a length measurement from the end hook 170 in one or more units (e.g., inches, centimeters, etc.), with divisions and subdivisions of such units clearly marked on the edge of tape 140 with numbering to show integer units of measure. The distance measurement indicia may include measurement numbers and tick marks indicating units or sub-units of measurement.
By affixing the end hook 170 to the anchor point, the self-retraction assembly 130 (which may be spring loaded in some cases) may be prevented from retracting the paid out portions of the tape 140 into the housing 110 (via the aperture 150). Similarly, when the locking assembly 160 is in a locked position, a force (e.g., a pinching force) may be placed on the tape 140 to prevent retraction or motion of the reel assembly 120. As such, the locking assembly 160 may prevent the self-retraction assembly 130 from retracting the paid out portions of the tape 140. However, when the end hook 170 is not anchored and the locking assembly 160 is unlocked, the self-retraction assembly 130 may cause the reel assembly 120 to wind the tape 140 back onto the reel assembly 120.
According to some example embodiments, when the tape 140 is paid out through the aperture 150, the tape 140 will extend relatively straight out of the aperture 150 (although some sagging or drooping may be noticed due to the weight of the tape 140). The tape 140 can be extended in a guided fashion toward an intended target anchor point while the tape 140 continues to have sufficient rigidity to standout.
Additionally, the distance measuring apparatus 100 may include an optical measurement assistance assembly 180. According to some example embodiments, the optical measurement assistance assembly 180 may include a camera that is configured to capture an image of the extended tape 140 during a measurement workflow by a user. The captured image may be evaluated and analyzed to determine a measurement based on a measurement position that is included in the image as further described herein. The optical measurement assistance assembly 180 may also include other components as described herein according to some example embodiments.
The touch control 210 may be any type of touch control (e.g., push button switch, capacitive touch sensor, etc.). The touch control 210 may permit a user to request that a measurement be taken. As further described below, upon touching or pressing the touch control 210, a request in the form of an image capture signal may be sent to the camera 230 to capture an image of the measuring tape 140. As seen in
The display 220 may be configured to present to a user the measurement that is being taken. In this regard, the display 220 may be a liquid crystal display configured to provide information to the user of the distance measuring apparatus 200.
The camera 230 may be affixed to or disposed within the housing 110. The camera 230 may be a digital camera capable of capturing an image of the measuring tape 140. The camera 230 may be disposed in a fixed position relative to the housing 110 and therefore a field of view of the camera 230 may be static relative to the housing 110, according to some example embodiments. The light element 240, which may be an light emitting diode (LED), may illuminate the tape 140 with an illumination indicator 246 at a predetermined measurement position 245 to indicate the measurement position 245 to the user. The illumination indicator 246 may be, for example, a red line that extends beyond the edges of the measuring tape 140. Further, the illumination indicator 246 may be presented as a moving point that draws a line back and forth at the measurement position 245.
As such, the camera 230 may be pointed at a fixed field of view relative to the housing 110 and the measuring tape 140 may move relative to and through the field of view of the camera 230 as the measuring tape 140 is extended out of the housing 110. Further, the measurement position 245 may be a fixed position within the field of view of the camera 230, and the measurement position 245 may be indicated by an illumination indicator 246 provided by a light element 240.
With reference to
Upon aligning the desired measurement with the measurement position 245, the user may depress or touch the touch control 210 thereby sending an image capture signal to the processing circuitry to be received by the processing circuitry. In response, the processing circuitry may be configured to cause the camera 230 to capture an image of the measuring tape 140. In this regard, the camera 230 may capture an image of the camera 230's field of view 300 shown in
Having captured the image including the distance measurement indicia 200, including the numbering, the tick marks, and the illumination indicator 246, the processing circuitry may be configured to perform an image analysis to determine a measurement. In this regard, the measurement is a value (e.g., 6 feet 10 inches, 6.5 feet, 3 meters, or the like). Since the illumination indicator 246 indicates the measurement position 245, the processing circuitry may use the distance measurement indicia 200 to determine where the measurement position 245 is on the measuring tape 140. In the example of
Upon determining the measurement, the processing circuitry may be configured to store the measurement in a memory device. The memory device may be housed within the housing 110 or the memory device may be remote. In this regard, the processing circuitry may leverage the wireless communications interface to communicate the measurement to, for example, a mobile terminal (e.g., via Bluetooth) or a network (e.g., via WIFI). In this regard, the measurement may be stored on the mobile terminal or on a cloud server. Additionally, the processing circuitry may present the measurement on the display 220.
Another example embodiment of a distance measuring apparatus 400 is shown in
In this regard, the distance measuring apparatus 400 may comprise a tape measure 405 having a tape measure component 410, a mobile terminal 415, and a camera component 420 having a camera 423. These elements may operate together to assist a user with making measurements using captured image analysis. The tape measure 405 may mechanically operate similar to the distance measuring apparatus 100 described above with respect to
The mobile terminal 415 may be any type of smart phone, tablet, or the like that is configured to run, for example, an application (or “app”) that configures the mobile terminal 415 to assist with taking measurements. According to some example embodiments, the mobile terminal 415 may be affixed to or incorporated into another tool, such as a power tool (e.g., saw) that may, for example, be configured to cut materials that have been measured. The mobile terminal 415 may be a core component of the optical measurement assistance assembly for distance measuring apparatus 400 as further described below, with the tape measure 405 (with the tape measure component 410) and the camera component 420 operating as peripheral devices. The mobile terminal 415 may include processing circuitry configured to, for example, receive and analyze a captured image of the measuring tape 140 of tape measure 405. In this regard, the mobile terminal 415 may include a communications interface capable of linking with the tape measure component 410 and the camera component 420 via, for example, Bluetooth.
The camera component 420 may include a camera 423, which may be a digital camera. The camera component 420 may also include a communications interface for linking with the mobile terminal 415. The camera component 420 may include a mounting assembly configured to affix the camera component 420 and the camera 423 to a user-wearable article such as a helmet, hat, glasses, or the like that may permit the field of view of the camera 423 to be pointed in a direction of a field of view of a user. In this regard, the camera component 420 may also include a light element 421 that forms an illumination indicator for the user to assist in aiming the camera's field of view.
With reference to
With reference to
Upon aligning the desired measurement with the tip 412 of the pointing member 411, the user may depress or touch a touch control on the tape measure component 410 thereby sending an image capture signal to the processing circuitry of the mobile terminal 415 to be received by the processing circuitry. In response, the processing circuitry may be configured to transmit a signal to the camera component 420 to cause the camera 423 to capture an image of the field of view 424 of the camera 423, which should include the measuring tape 140 and the tip 412. In this regard, the camera 423 may capture an image of the camera 423's field of view 424 as shown in
Having captured the image including the distance measurement indicia 200 including the numbering, the tick marks, and the tip 412, the camera component 420 may transmit the captured image to the processing circuitry of the mobile terminal 415 for analysis to determine the measurement. The processing circuitry of the mobile terminal 415 may be configured to perform an image analysis to determine the measurement. The processing circuitry of the mobile terminal 415 may be configured to isolate the tip 412 in the image (possibly based upon the tip 412's color) to determine the measurement position 425 and, based on the measurement position 425, determine the closest tick marks of the distance measurement indicia 200. Accordingly, based on the measurement position 425 and the distance measurement indicia 200, the measurement may be determined. In the example of
Upon determining the measurement, the processing circuitry may be configured to store the measurement in a memory device of the mobile terminal 415. The processing circuitry may alternatively or additionally leverage the wireless communications interface of the mobile terminal 415 to communicate the measurement to, for example, a network (e.g., via WIFI). In this regard, the measurement may be stored on the mobile terminal 415 or on a cloud server. Additionally, the processing circuitry may transmit the measurement to the tape measure component 410 to present the measurement on the display.

The communication interface 1040 may include one or more interface mechanisms for enabling communication with other devices external to apparatus 700, via, for example, a network, such as a local area network. In some cases, the communication interface 1040 may be any means such as a device or circuitry embodied in either hardware, or a combination of hardware and software that is configured to receive or transmit data from/to devices in communication with the processing circuitry 1010.

In this regard, via the user interface 1050, the processing circuitry 1010 may be configured to receive inputs from a user via the touch control 1051, which may be the same or similar to the touch control 210 described earlier, or an audio input 1054 (e.g., a microphone). The touch control 1051 may be configured to send an image capture signal to the processing circuitry 1010 upon user interaction with the touch control 1051. The user interface 1050 may also output information to a user by, for example, driving a display 1052 (which may be the same or similar to the display 220) and outputting audio via audio output 1053, which may be for example, a speaker. According to some example embodiments, the user interface may also operably couple to other user input devices such as, for example, a keyboard, mouse, touch screen, or the like.
