Description

Technical Field

[0001] The present invention relates to a distance measurement method and a distance measurement device, and more particularly to a method and a device capable of locating and displaying a target object in a distance measurement device and further performing a distance measurement operation to increase accuracy. Background Art

[0002] In recent years, laser rangefinders have replaced traditional distance measurement methods and become the mainstream of distance measurement systems. Laser distance measurement can be divided into three methods: triangulation, time measurement, and confocal measurement. Currently, the most commonly used method is time measurement, which measures the time it takes for the laser to travel back and forth (Time of Flight, ToF). The ToF principle uses a sight or rangefinder to emit a coded laser beam from a pulsed infrared light source to a target. The ToF camera is responsible for receiving the laser beam reflected from the target and calculating the distance to the target according to the ranging formula. Due to the unique principle of lasers, even if the target is inaccessible, measurements can still be performed through the instrument.

[0003] Traditional laser sights or rangefinders operate by simply sending a laser beam through a transmitter toward a target. If the number of laser reflections received by the receiver exceeds a threshold, such as 60%, the ToF values ​​of those successfully received laser beams are calculated to derive the final measured distance as output. However, in some specialized applications, such as outdoor hunting and golf, rangefinders only provide distance and angle measurements, along with various range-based displays. In other words, rangefinders offer relatively limited functionality.

[0004] In these application scenarios, being able to locate and track one or more target objects, such as a companion, a hunting dog, or a golf hole, will allow users to better understand the location and status of themselves and the specific target object, allowing them to more fully understand the current status of the application and take necessary feedback in real time. Summary of the Invention

[0005] In view of this, the present invention provides a method for locating a target object in a ranging device and the ranging device thereof.

[0006] An embodiment of the present invention provides a method for locating a target in a ranging device, applicable to a ranging device. First, a signal processor of the ranging device processes a first signal from a first signal module corresponding to a first target, where the first signal includes at least position information. Next, a first target distance corresponding to the first target is determined based on the device position of the ranging device and the position information in the first signal. Thereafter, a laser ranging unit of the ranging device performs a ranging operation on the first target to obtain a first laser ranging result. A first icon corresponding to the first target is displayed on a display unit of the ranging device based on the first target distance or the first laser ranging result.

[0007] A ranging device according to an embodiment of the present invention includes at least a laser ranging unit, a signal receiver, a display unit, and a processing unit. A signal processor processes a first signal from a first signal module corresponding to a first target, wherein the first signal includes at least position information. The processing unit is coupled to the signal receiver and the display unit and determines a first target distance corresponding to the first target based on the device position of the ranging device and the position information in the first signal. The processing unit uses the laser ranging unit to perform a ranging operation on the first target to obtain a first laser ranging result, and displays a first icon corresponding to the first target on the display unit based on the first target distance or the first laser ranging result.

[0008] In some embodiments, a signal processor of a ranging device continuously processes a plurality of signals of a first signal module corresponding to a first target object. Then, the ranging device calculates a movement trajectory of the first target object based on the signals, and a display unit of the ranging device displays the movement trajectory of the first target object.

[0009] In some embodiments, the ranging device determines whether the strength of the first signal is below a threshold. When the strength of the first signal is below the threshold, the display unit of the ranging device displays a notification to remind the user that the first signal corresponding to the first target is about to be lost.

[0010] In some embodiments, a distance measuring device is provided with map data, wherein the map data defines a dangerous terrain area. Then, a display unit of the distance measuring device displays a prompt corresponding to the dangerous terrain area based on the map data, the device location of the distance measuring device, or the location information in the first signal.

[0011] In some embodiments, a distance measuring device is used to calibrate the distance to the first target based on the first laser ranging result. The signal processor determines the first relative position relative to the first target based on global positioning system technology, Wi-Fi positioning technology, or UWB (Ultra Wideband) positioning technology. The signal processor wirelessly receives the first signal transmitted by the first signal module corresponding to the first target, wherein the corresponding technology for receiving or transmitting the first signal is, for example, but not limited to, Bluetooth technology, Wi-Fi technology, or other communication technology, and a signal receiver is activated by the signal transmission module, or the signal transmission module is activated by the signal receiver.

[0012] In some embodiments, a signal receiver of a ranging device wirelessly receives a second signal transmitted by a second signal transmitting module corresponding to a second target, wherein the second signal includes at least position information. A second target distance corresponding to the second target is determined based on the device position corresponding to the ranging device and the position information in the second signal. A laser ranging unit of the ranging device then performs a ranging operation on the second target to obtain a second laser ranging result. The ranging device then corrects the first target distance based on the second target distance or the second laser ranging result.

[0013] In some embodiments, a signal receiver of a ranging device wirelessly receives a second signal transmitted by a second signal transmitting module corresponding to a second target, wherein the second signal includes at least position information. A second distance to the second target is determined based on the device position of the ranging device and the position information in the second signal. A second icon of the second target and the distance to the second target are displayed on a display unit of the ranging device based on the second relative position.

[0014] In some embodiments, the processing unit determines the first relative position relative to the first target object based on global positioning system (GPS) technology, Wi-Fi positioning technology, or UWB (Ultra Wideband) positioning technology.

[0015] In some embodiments, the display unit includes a high-resolution dot-matrix OLED (Organic Light-Emitting Diode) or a micro OLED.

[0016] The above method of the present invention may be implemented in the form of program codes. When the program codes are loaded and executed by a machine, the machine becomes an apparatus for implementing the present invention.

[0017] In this case, simply attaching a signal transmitter accessory to the target person or object allows the device's location and movement trajectory to be directly displayed on the distance-measuring device's display unit, enhancing convenience while hunting or golfing. Furthermore, the distance actually measured by the distance-measuring device can be used to correct the estimated distance of the signal transmitter accessory, which cannot be measured, thereby increasing accuracy. Furthermore, when locating and tracking a target, this device can display a warning on the display unit when the target is about to leave the connection range, and can also provide warnings about dangerous terrain areas in the environment.

Figure 3 The laser ranging unit according to an embodiment of the present invention is shown.

[0036] Figure 4 The method for locating a target object in a distance measuring device according to an embodiment of the present invention is shown. The method for locating a target object in a distance measuring device according to an embodiment of the present invention is applicable to Figure 1 or Figure 2 distance measuring device.

[0037] As in step S410, the signal receiver of the ranging device is used to wirelessly receive the first signal transmitted by the first signal transmitting module corresponding to the corresponding first target object. As mentioned above, the signal transmitting module can be set on a target object, and use GPS technology, Wi-Fi technology, and / or UWB positioning technology to send a signal with location information. Then, as in step S420, the first relative position of the corresponding first target object is determined based on the device position of the corresponding ranging device and the location information in the first signal. It is noted that, in some embodiments, the processing unit of the ranging device can also determine the first relative position of the corresponding first target object based on GPS technology, Wi-Fi positioning technology, or UWB positioning technology. Thereafter, as in step S430, the display unit of the ranging device is used to display the first icon of the corresponding first target object based on the first relative position.

[0038] Figure 5 A method for locating a target in a distance measuring device according to another embodiment of the present invention is shown. The method for locating a target in a distance measuring device according to an embodiment of the present invention is applicable to Figure 1 or Figure 2 distance measuring device.

[0039] In step S510, a signal receiver of a ranging device wirelessly receives a first signal transmitted by a first signal transmitting module corresponding to a first target object. As previously described, the signal transmitting module can be mounted on a target object and transmit a signal containing location information using GPS, Wi-Fi, and / or UWB positioning technology. In step S520, a first relative position of the first target object is determined based on the device position of the ranging device and the location information in the first signal. Similarly, in some embodiments, the processing unit of the ranging device can also determine the first relative position of the first target object based on GPS, Wi-Fi, or UWB positioning technology. Next, in step S530, a first target distance between the ranging device and the first target object is determined based on the device position of the ranging device and the location information in the first signal. In other words, in some embodiments, the first target distance of the first target object can be determined based on the device position of the ranging device and the location information in the first signal. Then, in step S540 , the display unit of the distance measuring device is used to display a first icon corresponding to the first target and a first target distance corresponding to the first target according to the first relative position.

[0040] Figure 11An example of a distance measuring device locating a target is shown. As shown in the figure, the distance measuring device 100 can receive a signal transmitted by a signal transmitting module in a target LRF_TAG_A and locate the target. The display unit 120 of the distance measuring device 100 can display the icon RD of the distance measuring device 100 and display the corresponding icon TA and the distance to the target according to the relative position of the target LRF_TAG_A, as shown in FIG. Figure 12 shown.

[0041] Figure 6 The method for calibrating the distance of a target object according to an embodiment of the present invention is shown. The method for calibrating the distance of a target object according to an embodiment of the present invention is applicable to Figure 2 First, in step S610, a laser ranging unit of the ranging device is used to perform a ranging operation on a first target to obtain a first laser ranging result. Then, in step S620, the distance to the first target is corrected based on the first laser ranging result. It should be noted that the distance to the first target is determined based on the device position of the ranging device and the position information in the first signal.

[0042] It should be noted that in some embodiments, when a ranging device simultaneously receives signals corresponding to a first target and a second target, and the first target is not within the field of view of the laser ranging unit, while the second target is within the field of view of the laser ranging unit, the laser ranging unit can perform a ranging operation on the second target within the field of view to obtain a second laser ranging result, and use the second laser ranging result to correct the first target distance corresponding to the first target that is not within the field of view. Because both the first and second targets are transmitted / detected via signals, the signals can be coordinated for correction. Notably, in some embodiments, when the ranging device simultaneously receives signals corresponding to the first and second targets, the second target distance corresponding to the second target can be determined based on the device position of the ranging device and the position information in the second signal corresponding to the second target, and the first target distance can be corrected based on the second target distance and / or the second laser ranging result.

[0043] Figure 7 A method for locating a target in a distance measuring device according to another embodiment of the present invention is shown. The method for locating a target in a distance measuring device according to an embodiment of the present invention is applicable to Figure 1 or Figure 2 In this embodiment, the moving trajectory of the target object can be tracked.

[0044] First, as in step S710, a signal receiver of a ranging device is used to wirelessly and continuously receive a plurality of signals transmitted by a first signal transmitting module corresponding to a corresponding first target object. As previously mentioned, the signal transmitting module can be set on a target object, and use GPS technology, Wi-Fi technology, and / or UWB positioning technology to send a signal with location information. Then, as in step S720, the first relative position of the corresponding first target object is determined based on the device position of the corresponding ranging device and the location information in the first signal, and the movement trajectory of the corresponding first target object is calculated based on the signal received by the first target object. Similarly, in some embodiments, the processing unit of the ranging device can also determine the first relative position of the corresponding first target object based on GPS technology, Wi-Fi positioning technology, or UWB positioning technology. Thereafter, as in step S730, the display unit of the ranging device is used to display the first icon of the corresponding first target object and the movement trajectory of the corresponding first target object based on the first relative position. Continued Figure 11 For example, when the target object LRF_TAG_A moves and continuously receives signals from the target object LRF_TAG_A, the ranging device 100 can calculate the moving trajectory RT of the target object LRF_TAG_A and display it on the display unit 120, such as Figure 13 shown.

[0045] Note that in this case, further management can be performed on the target object of positioning / tracking.

[0046] Figure 8 A method for locating a target in a distance measuring device according to another embodiment of the present invention is shown. The method for locating a target in a distance measuring device according to an embodiment of the present invention is applicable to Figure 1 or Figure 2 In this embodiment, the signal strength of the target object can be further judged and a reminder can be given.

[0047] First, as in step S810, determine whether the intensity of the first signal corresponding to the first target object is lower than a threshold value. It is noted that the threshold value can be adjusted according to different needs and applications, and the present invention does not limit this. When the intensity of the first signal is not lower than the threshold value (No in step S820), the process returns to step S810. When the intensity of the first signal is lower than the threshold value (Yes in step S820), as in step S830, a notification is displayed on the display unit of the ranging device to remind that the first signal of the corresponding first target object is about to be lost. Through this reminder, the user can react in advance before losing the first signal of the first target object.

[0048] Figure 9 A method for locating a target in a distance measuring device according to another embodiment of the present invention is shown. The method for locating a target in a distance measuring device according to an embodiment of the present invention is applicable to Figure 1 or Figure 2 In this embodiment, the distance measuring unit can provide prompts for dangerous areas in the environment.

[0049] First, in step S910, map data is provided to the ranging device, wherein the map data defines at least one hazardous terrain area. Next, in step S920, a display unit of the ranging device displays a warning corresponding to the hazardous terrain area based on the map data, the device location of the ranging device, and / or the location information in the first signal. This warning can help the user avoid entering the hazardous terrain area, or prevent their companions from entering the hazardous terrain area.

[0050] Figure 10 A method for locating a target in a distance measuring device according to another embodiment of the present invention is shown. The method for locating a target in a distance measuring device according to an embodiment of the present invention is applicable to Figure 1 or Figure 2 In this embodiment, the ranging device can locate multiple targets simultaneously.

[0051] In step S1010, a signal receiver of a ranging device wirelessly receives a first signal transmitted by a first signal transmitting module corresponding to a first target. In step S1020, a first relative position of the first target and a first target distance between the ranging device and the first target are determined based on the device position of the ranging device and the position information in the first signal. Similarly, in some embodiments, the processing unit of the ranging device may also determine the first relative position of the first target based on GPS technology, Wi-Fi positioning technology, or UWB positioning technology. Next, in step S1030, a second signal transmitted by a second signal transmitting module corresponding to a second target is wirelessly received by the signal receiver of the ranging device. In step S1040, a second relative position of the second target and a second target distance between the ranging device and the second target are determined based on the device position of the ranging device and the position information in the second signal. Similarly, in some embodiments, the processing unit of the ranging device may also determine the second relative position of the second target based on GPS technology, Wi-Fi positioning technology, or UWB positioning technology. Then, in step S1050 , the display unit of the distance measuring device displays a first icon corresponding to the first target and a first target distance corresponding to the first target according to the first relative position, and displays a second icon corresponding to the second target and a second target distance corresponding to the second relative position.

[0052] Figure 14An example of a distance measuring device locating multiple targets is shown. As shown in the figure, the distance measuring device 100 can receive signals from the signal transmission modules in the target LRF_TAG_A, the target LRF_TAG_B, and the target LRF_TAG_C and locate them. The display unit 120 of the distance measuring device 100 can display the icon RD of the corresponding distance measuring device 100, and display the corresponding icon and the target distances TA, TB, and TC according to the relative positions of the target LRF_TAG_A, the target LRF_TAG_B, and the target LRF_TAG_C, as shown in FIG. Figure 15 shown.

[0053] Therefore, through the present method for locating a target object in a distance measuring device and its distance measuring device, the target object can be located and displayed in the distance measuring device, and further distance measurement can be performed to increase accuracy. As previously mentioned, in outdoor hunting and golfing applications, rangefinders have relatively simple functional applications, lacking positioning, finding, and searching functions. This present invention extends this application. In this case, by simply using a signal transmitting accessory carried by the target person or object, the person's position and movement trajectory can be directly displayed on the display unit of the distance measuring device, thereby increasing convenience when hunting or playing golf. In addition, the distance actually measured by the distance measuring device can be used to correct the estimated distance of the signal transmitting accessory, which cannot be actually measured, thereby increasing its accuracy. Furthermore, when locating and tracking a target object, this invention can also provide a prompt on the display unit when the target object is about to leave the connection range and provide a warning of dangerous terrain areas in the environment.

The program code may be embodied on a physical medium such as a floppy disk, optical disk, hard disk, or any other machine-readable (e.g., computer-readable) storage medium, or in a computer program product in a tangible form, wherein when the program code is loaded and executed by a machine such as a computer, the machine becomes an apparatus for participating in the present invention. The program code may also be transmitted via some transmission medium such as a wire or cable, optical fiber, or any other transmission method, wherein when the program code is received, loaded, and executed by a machine such as a computer, the machine becomes an apparatus for participating in the present invention. When implemented on a general-purpose processing unit, the program code, in combination with the processing unit, provides a unique device that operates similarly to application-specific logic circuits.
