Technical Field

[0001] This invention relates to a data glasses, a case (Etui), and a method for calibrating the data glasses. Background Technology

[0002] WO 2023 / 091421 discloses the recalibration of data glasses in the charging housing for data glasses. Summary of the Invention

[0003] A method for calibrating optical instruments, particularly data glasses, binoculars, telescopes, microscopes, periscopes, virtual reality glasses, mixed reality glasses, cycling glasses, diving goggles, motorcycle helmet visors, protective eyewear, or instruments used for ophthalmic examinations, wherein calibration is performed on the optical instrument when, in particular, the box containing the optical instrument is identified as closed. In the case of a closed box, the prerequisites for calibration are defined. The calibration is performed automatically. The optical instrument must be calibrated to accurately perform its function. For example, calibration is performed during manufacturing. During use of the optical instrument, changes may occur within it, necessitating recalibration. For example, after a drop (in which case the optical instrument bends), deviations in the optical instrument can be anticipated. Furthermore, distortion of the tilting mirror in the optical path of the optical instrument can cause deviations. Calibration within the box compensates for these changes. This improves functionality and thus the user experience when using the optical instrument. Furthermore, the method simplifies operation of the optical instrument by the user.

[0004] In one example, the box includes an illuminateable calibration pattern, wherein the optics include an optical sensor. Within the enclosed box, the calibration pattern is illuminated by a light source, particularly a light-emitting diode, display, or self-emissive light source, mounted on or within the optics. The illuminated calibration pattern is detected by the optical sensor, and calibration of the optics is performed based on the illuminated calibration pattern detected by the sensor. This method uses the calibration pattern integrated into the box for automatic calibration. The calibration pattern is illuminated in the manner required for the calibration according to a pre-defined illumination process. Here, the self-emissive calibration pattern does not require an additional power supply from the box.

[0005] The optical instruments can be configured to include systems for tracking eye movements or for overlaying visible information generated by the optical instruments. Alternatively, it can extend the view of reality through optical instruments, wherein the system includes sensors, and at least one parameter of the system is calibrated based on an illuminated calibration pattern detected by the sensors when calibrating the optical instruments. This means that the system is used to calibrate the system based on a calibration pattern detected by the sensors using the system.

[0006] The system for tracking eye movement can be configured to track eye movement using laser feedback interferometry, wherein the sensor is configured to detect the reflected laser beam used to perform the laser feedback interferometry, or the system for tracking eye movement can be configured to track eye movement using camera images, wherein the sensor is configured to detect the camera images.

[0007] The calibration pattern can be arranged in a movable manner within a box, wherein the box includes a motor for moving the calibration pattern, and in the case of a closed box, the motor moves the calibration pattern to different relative orientations relative to the optical instrument, predetermined by a pre-defined calibration procedure. Thus, the calibration is performed in these different relative orientations.

[0008] The enclosure can be configured to include optical sensors, particularly photodiodes, wherein the optical instruments include a laser. Within the enclosed enclosure, a laser beam is generated by the laser, and measurements are determined by the optical sensors. These measurements include the measured power of the laser beam, and the optical instruments are calibrated based on these measurements. Thus, the power of the laser is calibrated.

[0009] The optical apparatus can be configured to include a laser configured to generate a laser beam, and a micromirror configured to deflect the laser beam. The housing includes at least one optical sensor configured to detect the deflected laser beam. Within the enclosed housing, the laser beam is generated by the laser, deflected in different directions by the micromirror, and a measurement is determined by the at least one sensor. This measurement includes the positional resolution and / or angular resolution of the deflected laser beam, and calibration of the optical apparatus is performed based on these measurements. Thus, changes in the optical path of the optical apparatus are taken into account during calibration.

[0010] For communication between the optical instrument and the housing, the optical instrument and the housing can be configured to communicate via a communication interface, particularly an electrical contact connection or a wireless connection, wherein the measurement is transmitted from the housing to the optical instrument via the communication interface, and the calibration is performed based on the measurement.

[0011] It can be configured such that markings are arranged on the optical instrument, wherein the housing includes a sensor configured to detect the markings when the optical instrument is in the enclosed housing at a predetermined orientation. Calibration of the optical instrument begins when the sensor detects that the optical instrument is in the enclosed housing at the predetermined orientation. This reliably performs the calibration at the predetermined orientation, improving the calibration results.

[0012] The optical apparatus used to perform the method includes a device for calibrating the optical apparatus, the device being configured to perform calibration of the optical apparatus when it is detected that the box containing the optical apparatus is closed, said optical apparatus being particularly data glasses, binoculars, telescopes, microscopes, periscopes, virtual reality glasses, mixed reality glasses, bicycle glasses, diving glasses, motorcycle helmet masks, protective glasses, or instruments used for ophthalmic examinations.

[0013] To enable autonomous calibration via optical instruments, the optical instruments may be configured to include optical sensors and light sources, particularly light-emitting diodes (LEDs). These instruments are configured to illuminate a calibration pattern arranged in a sealed box by the light source and detect the illuminated calibration pattern using the optical sensor. The devices for calibrating the optical instruments are configured to perform calibration based on the illuminated calibration pattern detected by the sensor.

[0014] The optical apparatus can be configured to include a system for tracking eye movements or a system for overlaying or expanding the reality visible through the optical apparatus using information generated by the optical apparatus. The system includes sensors, and the device for calibrating the optical apparatus is configured to calibrate at least one parameter of the system based on an illuminated calibration pattern detected by the sensors during the calibration of the optical apparatus. Thus, the system can be calibrated automatically.

[0015] For example, a system for tracking eye movement may be configured to track eye movement using laser feedback interferometry, wherein the sensor is configured to detect a reflected laser beam used to perform the laser feedback interferometry; or a system for tracking eye movement may be configured to track eye movement using camera images, wherein the sensor is configured to detect camera images.

[0016] For example, an optical instrument includes a laser, wherein a calibration device is configured to generate a laser beam within a sealed enclosure, and to determine a measurement using an optical sensor, wherein the measurement includes a measured power of the laser beam, and wherein the calibration device is configured to perform calibration of the optical instrument based on the measurement. Thus, the power of the laser beam can be automatically calibrated.

[0017] For example, an optical instrument includes a laser configured to generate a laser beam, wherein the optical instrument includes micromirrors configured to deflect the laser beam, and wherein a calibration device is configured to, within a sealed enclosure, generate the laser beam using the laser, deflect the laser beam in different directions using the micromirrors, and perform calibration of the optical instrument based on measurements including the positional and / or angular resolution of the deflected laser beam, determined using at least one optical sensor of the enclosure configured to detect the deflected laser beam within the sealed enclosure. Thus, the optical path of the optical instrument can be taken into account during calibration.

[0018] For communication between the optical instruments and the box, the optical instruments can be configured to communicate with the box via a communication interface, particularly an electrical contact connection or a wireless connection, wherein the calibration device is configured to receive measurements from the box via the communication interface and perform calibration based on the measurements.

[0019] It can be configured that a mark is placed on the optical instrument, and when the optical instrument is in a sealed box at a predetermined orientation, the mark can be detected by a sensor placed in the box for the optical instrument. This ensures that the calibration is performed only in the predetermined orientation.

[0020] The housing for the optical instrument includes an illuminateable calibration pattern and / or an optical sensor, particularly a photodiode, wherein the optical sensor is configured to determine a measurement, including the measured power of a laser beam generated by a laser of the optical instrument within the enclosed housing. The optical instrument can be automatically calibrated within this housing.

[0021] For example, the calibration pattern is arranged in a movable manner within a box, wherein the box includes a motor for moving the calibration pattern, and the box includes a device for moving the calibration pattern, with the aid of the motor, to different relative orientations relative to the digital glasses, according to a pre-defined calibration procedure, within the enclosed box. This enables calibration in different orientations.

[0022] For communication between the optical instrument and the box, the box can be configured to communicate with the optical instrument via a communication interface, particularly an electrical contact connection or a wireless connection, wherein the box is configured to transfer measurements from the box to the optical instrument via the communication interface.

[0023] The box can be configured to include a sensor configured to detect a mark placed on the optical instrument when the optical instrument is in the closed box at a predetermined orientation. The box is configured to initiate calibration of the optical instrument when the sensor detects that the optical instrument is in the closed box at the predetermined orientation. This ensures that calibration is performed only in the predetermined orientation. Attached Figure Description

The first lens 110 has holographic functionality. For example, the first lens 110 includes a holographic optical element 114. The first temple 110 includes...

[0037] In this example, the first temple 108 carries the projection device 116. For example, the projection device 116 is arranged in or fastened to the first temple 108.

[0038] The data glasses 102 are arranged in the box 104 in a predetermined orientation.

[0039] Optionally, the data glasses 102 includes a splice 118 that connects the first lens 106 and the second lens 108. For example, the case 104 includes a mechanical receiving portion 120 for the splice 118. In this example, the receiving portion 120 is configured to receive the splice 118 only when the data glasses 102 is in a predetermined orientation within the case 104. The data glasses 102 are mechanically secured in their orientation by the receiving portion 120 in the case 104.

[0040] Optionally, a marker 122 is arranged on the data glasses 102. In this example, a sensor 124 is arranged in the box 104, which is configured to detect the marker 122 of the data glasses 102 in the closed box 104 when the data glasses 102 is in a predetermined orientation.

[0041] Optionally, the data glasses 102 and the box 104 can be connected via a communication interface for communication with each other. The communication interface can be wirelessly configured, for example, as a Bluetooth interface. The communication interface can be implemented as an electrical contact connection.

[0042] In this example, box 104 includes a plug 126 for contact connection. In this example, data glasses 102 includes a socket 128 for contact connection.

[0043] The projection device 116 is configured to generate a light beam 130 for illuminating the holographic optical element 114 in a point-like manner or for scanning the holographic optical element 114.

[0044] For example, beam 130 is a laser beam. Data glasses 102 includes a laser for generating the laser beam. For example, projection device 116 includes this laser.

[0045] The beam 130 is at least partially reflected by the holographic optical element 114.

[0046] According to the first example, the box 104 includes a calibration pattern 132 that can be illuminated. In this example, the calibration pattern 132 is configured to reflect a beam of light 130 that is at least partially reflected by the holographic optical elements.

[0047] In this example, the calibration pattern 132 is secured in the box 104, in particular, it is firmly integrated into the box 104.

[0048] In this example, calibration pattern 132 includes at least one retroreflector 134. Optionally, calibration pattern 132 includes at least one ND filter 136.

[0049] The calibration pattern 132 may include a checkerboard pattern or a dot pattern composed of retroreflectors 134. The calibration pattern 132 may be three-dimensional, that is, it may include multiple different patterns arranged at different distances from each other.

[0050] The calibration pattern 132 may include a retroreflector 134 in front of which a plurality of ND filters 136 with different intensities are arranged. For example, the ND filters 136 are designed and arranged to perform intensity comparison or to adapt the power of the beam 130. For example, the ND filters 136 are arranged such that the power of the light source can be calibrated starting from a known initial output power and by means of different known ND filters in front of the retroreflector.

[0051] The calibration pattern 132 may include a reflector having an inverted pattern made of a material that absorbs the light beam 130.

[0052] The calibration pattern 132 may include a screen, such as an LCD display. For example, the screen is configured to turn the pattern or pixels on or off by polarization.

[0053] It can be configured such that an optical component is arranged in front of the calibration pattern 132 (not in...). Figure 1 (as shown in the figure). For example, the optics are configured to set the calibration pattern 132 to a desired object distance, such that the calibration pattern 132 appears to be infinitely far away.

[0054] In this example, the beam 130, which is at least partially reflected by the calibration pattern 132, is at least partially reflected by the holographic optical element 114.

The LFI sensor 138 is an example of a light source configured to generate a light beam 130. The LFI sensor 138 is also an example of an optical sensor configured to detect the light beam 130 reflected by a calibration pattern 132. The system can be configured to track eye movement using a camera, rather than the LFI sensor 138.

[0056] The data glasses 102 includes a control device 140. The control device 140 is an example of a device for calibrating the data glasses 102. The control device 140 is configured to calibrate at least one parameter of the data glasses 102 based on signals detected by an optical sensor (i.e., in the first example, by an LFI sensor 138 or a camera).

[0058] According to the first example, the calibration pattern 132 is illuminated by the LFI sensor 138.

[0059] The control device 140 may be configured to pre-define an illumination process by which the calibration pattern 132 is illuminated for calibration. For example, the illumination process pre-defines the points to be illuminated in a point-like manner by the light source or the order in which the points are illuminated in a point-like manner by the light source. The control device 140 is configured to manipulate the light source to illuminate the calibration pattern 132 according to the illumination process. In a first example, the control device 140 is configured to manipulate the LFI sensor 138 according to the illumination process.

[0061] The control device 140 can be configured to perform calibration by pre-given calibration procedures and moving the calibration pattern 132 according to the calibration procedures using a motor.

[0062] For example, a pre-defined calibration procedure is provided, through which the calibration pattern 132 is moved to different relative positions relative to the data glasses 102.

[0063] Box 104 can be configured to transmit the orientation of marker 122, detected by sensor 124, to data glasses 102. Control device 140 can be configured to enable (Freigabe) calibration using the accurate orientation of data glasses 102 relative to box 104 based on the orientation detected by sensor 123. For example, control device 124 is configured to perform calibration only when data glasses 102 is in box 104 at a predetermined orientation.

[0067] The data glasses 102 and box 104 according to the third example are constructed in the same manner as those according to the first example. Unlike the first example, the box 104 according to the third example does not include a calibration pattern, but instead includes an optical sensor 302 configured to detect the beam 130.

[0068] According to the third example, the measurement is detected using an optical sensor 302. For example, the optical sensor 302 is a camera, a photodiode, a photodiode assembly, or a passive sensor, such as a retroreflector.

[0095] The data glasses 102 and box 104 according to the seventh example are constructed as those according to the first example. Unlike the first example, the box 104 according to the seventh example includes a reflector 702. Unlike the first example, the data glasses 102 according to the seventh example includes a photodiode 704.

[0096] In this example, the reflector 702 is arranged in the box 104 such that when the data glasses 102 is positioned in the box 104 in a predetermined orientation, the reflector 702 deflects the light beam 130 to the photodiode 704.

[0098] exist Figure 8 The eighth example is schematically shown in the diagram, which includes data glasses 102 and a box 104 for data glasses 102.

[0099] The data glasses 102 and box 104 according to the eighth example are constructed as in the seventh example. Unlike the seventh example, in the eighth example, the reflector 702 is arranged in the box 104 such that when the data glasses 102 is positioned in the box 104, the reflector 702 deflects the portion of the light beam 130 reflected by the holographic optical element 114 to the photodiode 704.

[0100] The data glasses 102 are configured to perform calibration based on measurements of the beam 130 using a photodiode 704.

[0101] For example, beam 130 is a blue laser beam. Instead of a blue laser beam, other colors of laser beams can also be used. For multiple different light sources producing different light, a calibration can be set for each light source. This calibration can be implemented according to one example described. Data glasses 102 and box 104 can be configured to implement one or more of the calibrations, respectively.

[0102] exist Figure 5The diagram shows a flowchart of the steps for calibrating data glasses. This method can be implemented accordingly for other optical instruments, particularly binoculars, telescopes, microscopes, periscopes, virtual reality glasses, mixed reality glasses, cycling glasses, diving goggles, motorcycle helmet visors, protective eyewear, or instruments used for ophthalmic examinations. In this case, as described for data glasses 102, the optical instrument includes a corresponding calibration pattern, a corresponding light source, a corresponding optical sensor, a corresponding photodiode, or a corresponding mirror.

[0103] The method includes step 902.

[0104] In step 902, it is checked whether the box 104 containing the data glasses 102 is closed. If the box 104 containing the data glasses 102 is closed, step 904 is executed. Otherwise, step 902 is executed.

[0105] In this example, the data glasses 102 were used to identify that the box 104 containing the data glasses 102 was closed.

[0106] For example, when it is determined by using data glasses 102 that data glasses 102 and box 104 are connected to each other through communication interface 106, data glasses 102 can be used to identify that data glasses 102 is inside box 104.

[0107] For example, when it is determined by the data glasses 102 that the space in the box 104 darkens while the data glasses 102 is in the box 104, the data glasses 102 recognize that the box 104 is closed.

[0108] It can be configured such that a marker 122 is arranged on the data glasses 122 and the housing 102 includes a sensor 124 configured to detect the marker 122. The method can be configured to begin calibration of the data glasses 102 when the sensor 124 identifies the data glasses 102 as being in a pre-given orientation within the enclosed housing 104 based on the marker 122.

[0109] In step 904, the data glasses 102 are calibrated.

[0110] The calibration is performed in a manner that matches the type of data glasses 102 and the type of box 104.

[0111] The premise for the method of calibration by means of an illuminated calibration pattern is that the box 104 includes at least one calibration pattern and the data glasses 102 includes at least one optical sensor.

[0112] The premise for the method of calibration by means of an illuminated calibration pattern is that at least one calibration pattern in the closed box 104 can be illuminated by a light source mounted on the data glasses 102 or mounted in the box 104.

[0113] In the method for calibration using an illuminated calibration pattern, at least one illuminated calibration pattern is illuminated by a light source, and the illuminated calibration pattern is detected by an optical sensor. In the method for calibration using an illuminated calibration pattern, the data glasses 102 are calibrated based on the illuminated calibration pattern detected by the sensor.

[0114] Data glasses 102 may include a system for tracking eye movements or a system for overlaying or expanding the reality that can be seen through data glasses 102 with the help of information generated by data glasses 102.

[0115] A method for calibration using an illuminated calibration pattern is implemented, for example, for calibrating a system including an optical sensor. When calibrating data glasses 102, at least one parameter of the system is calibrated based on the illuminated calibration pattern detected by the sensor.

[0116] The method for calibration using an illuminated calibration pattern can be configured such that the calibration pattern is arranged in a manner that allows it to move within a housing 104 via a motor. In the case of a closed housing 104, the calibration pattern is moved by the motor to different relative positions relative to the data glasses 102, predetermined by a pre-defined calibration procedure.

[0117] The calibration method can be implemented based on a measurement, which includes the measured power of the laser beam.

[0118] For example, the measurement can be detected using an optical sensor, such as a photodiode or multiple photodiodes.

[0119] For example, the optical sensor is arranged in the box 104 or on the data glasses 102.

[0120] For example, the measurement is performed using a light beam, particularly a laser beam, generated by the data glasses 102. Alternatively, the measurement can be performed using light from a light source arranged in the housing 104.

[0121] For example, the data glasses include a laser, wherein a laser beam is generated by the laser within a sealed case, and the measurement is determined by an optical sensor. This measurement includes the measured power of the laser beam. For example, calibration of the data glasses 102 is performed based on this measurement.

[0122] The data glasses 102 may be configured to include a laser configured to generate a laser beam. The data glasses 102 may also include micromirrors configured to deflect the laser beam. The housing 104 may include at least one optical sensor configured to detect the deflected laser beam.

[0123] The method can be configured to generate a laser beam within a sealed box 104 using a laser, deflect the laser beam in different directions using a micromirror, and determine measurements using at least one sensor. These measurements include the positional resolution and / or angular resolution of the deflected laser beam. The method can also be configured to calibrate the data glasses 102 based on these measurements, which include the positional resolution and / or angular resolution of the deflected laser beam.

[0124] For example, the measurement detected in box 104 in this method is transmitted from box 104 to data glasses 102 via a communication interface, and the calibration is performed in data glasses 102 based on the measurement.
