[0046] The arbitrary plane angle measurement laser ranging module and device are described in detail below in conjunction with Figures 1 to 14. In one embodiment, an arbitrary plane angle measurement laser ranging module 200 is shown in Figure 1, and the arbitrary plane angle measurement laser ranging module 200 includes a laser ranging component 210, an angle measurement component 220, a laser angle indication component 230 and a controller 240; the controller 240 is respectively conductively connected to the laser ranging component 210, the angle measurement component 220 and the laser angle indication component 230; in one embodiment, the laser ranging component 210 is used for distance measurement, the angle measurement component 220 is used for measuring the angle change, the laser angle indication component 230 is used for indicating the angle position, and the controller 240 is used to transmit electrical signals to realize distance measurement control and angle measurement control, and obtain the measurement results of the laser ranging component 210 and the angle measurement component 220. In one embodiment, the angle measurement component 220 is an angle sensor or an inclination sensor, which can be purchased directly from the market or developed by itself. It should be noted that the measured angle β obtained by the angle measuring component 220 can be a non-directional angle or a directional angle, i.e., a vector angle. Moreover, the structural design of the present application has the advantages of low cost, small size, high reliability and strong practicality.

[0047] In addition, it should be noted that in each embodiment of the present application, the controller 240 is a product that can be directly purchased from the market, or can be made by itself. In one embodiment, the controller 240 can be a packaged control chip, or a circuit board with a control module, etc. The embodiments of the present application do not limit the specific implementation method and control method of the controller 240.

[0048] In order to facilitate the control of the switches of the laser ranging component 210, the angle measuring component 220, the laser angle indicating component 230 and the controller 240, for example, to start or shut down the ranging function, in combination with Figures 2 and 3, in one embodiment, the arbitrary plane angle measurement laser ranging module 200 also includes a control button 250, and the control button 250 is conductively connected to the controller 240, and is used to start or shut down the controller 240, start or shut down the laser ranging component 210 through the controller 240, start or shut down the angle measuring component 220 through the controller 240, start or shut down the laser angle indicating component 230 through the controller 240, start or shut down the arbitrary plane angle measurement laser ranging module 200 as a whole, etc.

[0049] The ranging function is mainly realized by the laser ranging component 210. In one embodiment, the laser ranging component 210 is configured to emit ranging light 213 and receive reflected light 214. In combination with Figures 4 and 5, further, in one embodiment, the laser ranging component 210 includes a laser emitting component and a laser receiving component, and the laser emitting component and the laser receiving component are respectively conductively connected to the controller 240; wherein, the laser emitting component is configured to emit ranging light 213, that is, the laser emitting component is configured to emit ranging light 213 under the control of the controller 240, which can also be understood as the controller 240 is configured to control the laser emitting component to emit ranging light 213; the laser receiving component is configured to receive reflected light 214, that is, the laser receiving component is configured to receive reflected light 214 under the control of the controller 240, which can also be understood as the controller 240 is configured to control the laser receiving component to receive reflected light 214. Specifically, in one embodiment, the laser distance measuring component 210 or its laser emitting component is provided with an emitting end 211, through which the distance measuring light 213 is emitted; the laser distance measuring component 210 or its laser receiving component is provided with a receiving end 212, through which the reflected light 214 is received. It is understandable that it is well known to those skilled in the art that the reflected light 214 is formed by the distance measuring object reflecting the distance measuring light 213.

[0050] As mentioned above, the angle measuring component 220 can quickly obtain the rotation angle of the arbitrary plane angle measurement laser ranging module 200 itself by using an angle sensor or other products. However, in order to associate the angle measured by the angle measuring component 220 with the actual measured object, in combination with Figures 6 and 7, in each embodiment, the laser angle indication component 230 is configured to emit a laser indication line; the angle measuring component 220 is configured to determine the measurement angle β according to the rotation degree of the arbitrary plane angle measurement laser ranging module 200 when the laser angle indication component 230 emits the laser indication line. Such a design, through the angle measuring component 220 and the laser angle indication component 230, can measure any relative rotation angle relative to itself at different times or points in any plane, and can also measure the angle between any two or more objects on the same plane. Compared with the traditional technical solution that can only measure the relative rotation angle relative to itself at different times or points in the horizontal plane or vertical plane, the flexibility of angle measurement and the wide range of application scenarios are greatly improved.

[0051] Specifically, in one embodiment, the laser indicator line includes a laser reference line 231 and a laser target indicator line 232, and the laser angle indication component 230 is configured to emit the laser reference line 231 and the laser target indicator line 232; the angle measurement component 220 is configured to determine the measurement angle β between the laser reference line 231 and the laser target indicator line 232 as the rotation degree of the arbitrary plane angle measurement laser ranging module 200 according to the angle change between the laser reference line 231 and the laser target indicator line 232. In one embodiment, the laser angle indication component 230 is also configured to calibrate and return to zero before measurement. Such a design can measure any rotation angle relative to itself in any plane by emitting a laser indicator line for angle indication, especially by adopting the implementation method of emitting a laser reference line 231 in combination with a laser target indicator line 232, and providing a laser indicator line indication or a line marking rotation angle function after measuring the rotation angle, thereby improving the convenience of use.

[0052] In order to avoid confusion between the lasers emitted by the laser ranging component 210 and the laser angle indicating component 230 and thus affect the identification of the angle, in conjunction with FIG5 , in one embodiment, the ranging light 213 and the laser reference line 231 have a preset angle α. In one embodiment, the preset angle α is 60 to 120 degrees. As shown in FIG6 , in this embodiment, the preset angle α is 90 degrees; in other embodiments, the preset angle α may also be 60, 75, 80, 85, 95, 100, 105, 110 or 120 degrees. The design of the preset angle α is conducive to avoiding interference between the ranging light 213 and the laser reference line 231, which makes it difficult for the user to determine the position of the laser indicating line, especially the laser target indicating line 232, and causes errors in angle measurement.

[0053] In order to measure the angles of multiple positions relative to the same reference position, in one embodiment, the laser angle indication component 230 is configured to adjust the emission angle and emit at least two laser target indication lines 232. That is, the laser angle indication component 230 adjusts the emission angle and emits at least two laser target indication lines 232 under the control of the controller 240, or the laser angle indication component 230 emits at least two laser target indication lines 232 under the control of the controller 240 after adjusting the emission angle. The remaining embodiments are similar and will not be described in detail. Such a design can not only measure the angle between any two objects on the same plane, but also measure the angle between multiple objects on the same plane, which is conducive to measuring the angles of multiple positions relative to the same reference position, thereby realizing multi-angle measurement based on the same reference position, and greatly improving the efficiency of multi-angle measurement based on the same reference position.

[0054] In order to accurately achieve angle measurement, in one embodiment, the laser reference line 231 is the 0° position indicator line of the laser angle indicator assembly 230, or the position of the first measured object 910 is used as the 0° position indicator line of the laser angle indicator assembly 230; the laser target indicator line 232 is the position indicator line of the arbitrary plane angle measurement laser ranging module 200 rotated relative to itself at a certain measured angle, or the position indicator line of the arbitrary plane angle measurement laser ranging module 200 at the second measured object 920. In one embodiment, the laser angle indicator assembly 230 is also configured to perform calibration and zeroing according to the position of the first measured object 910. Such a design is conducive to the cooperation between the angle measuring component 220 and the laser angle indicating component 230 to accurately measure the corresponding measured angle, or measure the angle of the second measured object 920. The laser indicator line can also be used to indicate or mark the rotation angle, so that any relative rotation angle relative to itself at different times or points can be measured in any plane, or the angle between any two or more objects on the same plane can be measured, so as to improve the flexibility of angle measurement and the wide range of application scenarios.

[0055] In order to obtain power, further, in one embodiment, the controller 240 is configured to be conductively connected to a power supply module 260, and the laser distance measuring component 210, the angle measuring component 220 and the laser angle indicating component 230 are powered by the power supply module 260. In one embodiment, the arbitrary plane angle laser distance measuring module 200 further includes a power supply module 260, and the power supply module 260 is conductively connected to the controller 240, the laser distance measuring component 210, the angle measuring component 220 and the laser angle indicating component 230; or, the power supply module 260 is conductively connected to the controller 240, so as to conductively connect the laser distance measuring component 210, the angle measuring component 220 and the laser angle indicating component 230 through the controller 240.

[0056] In one embodiment, an arbitrary plane angle measurement laser ranging device 100 is shown in FIG. 10 and FIG. 11, which includes a housing 300 and an arbitrary plane angle measurement laser ranging device 100 described in any embodiment, wherein the arbitrary plane angle measurement laser ranging module 200 is disposed in the housing 300, and the control button 250 of the arbitrary plane angle measurement laser ranging module 200 is exposed on the housing 300. In one embodiment, it can be understood that the control button 250 can be provided with a housing, and the housing is exposed on the housing 300, that is, exposed outside the housing 300. Such a design, through the angle measurement component 220 and the laser angle indication component 230, can measure any relative rotation angle relative to itself at different times or points in any plane, or measure the angle between any two or more objects on the same plane, thereby improving the flexibility of angle measurement and the wide range of application scenarios; and by emitting a laser indication line for angle indication, a laser indication line indication or a line rotation angle function is provided after the rotation angle is measured, thereby improving the convenience of use.

[0057] In order to facilitate display of measurement results, in one embodiment, as shown in FIG12 , the arbitrary plane angle measurement laser ranging device 100 further includes a display module 400, which is disposed on the housing 300 and is conductively connected to the controller 240 of the arbitrary plane angle measurement laser ranging module 200. If the display module 400 is not provided, a communication module conductively connected to the controller 240 may also be provided, and the communication module is used to send the measurement results of the controller 240 to the target terminal.

[0058] In one embodiment, before measuring the angle, the arbitrary plane angle measurement laser ranging device 100 is calibrated as shown in FIG. 13, and the laser reference line 231 is calibrated using the first measured object 910, and then the rotation angle of the second measured object 920 relative to the first measured object 910 is measured as shown in FIG. 14 to obtain the measured angle β.

[0059] In conjunction with Figures 1 to 14, an embodiment of a specific application is given below, and the arbitrary plane angle measurement laser distance measuring device 100 is further illustrated. The arbitrary plane angle measurement laser distance measuring device 100 is a laser distance measuring device with an arbitrary plane angle measurement function, which includes a housing 300, and a movement arranged in the housing 300 as the arbitrary plane angle measurement laser distance measuring module 200, the movement includes a laser distance measuring component 210, which is used to measure the distance between the measured target and the laser distance measuring device, that is, the arbitrary plane angle measurement laser distance measuring device 100, and send distance information, which can be sent to the controller 240 or directly to the display module 400, and can also be directly sent to the target terminal; an angle measuring component 220, which is used to measure the rotation angle of the controller 240 relative to itself, or the relative angle between the measured target and the controller 240, and send angle information; a laser angle indication component 230, which is used to emit a laser indication line; and a controller 240.

[0060] The laser distance measuring component 210, the angle measuring component 220, and the laser angle indicating component 230 are all connected to the controller 240, which is used to process distance information and angle information, and to control the laser angle indicating component 230 to emit a laser indicating line. It can also be used to control the laser distance measuring component 210 to emit a distance measuring light 213.

[0061] In this embodiment, the laser distance measuring component 210 includes a laser emitting component and a laser receiving component, and the angle measuring component 220 can be an angle sensor or an inclination sensor. The laser indication line emitted by the laser angle indication component 230 includes a laser reference line and a laser target indication line, the laser reference line is the 0° position indication line of the controller 240, and the laser target indication line is the position indication line of the controller 240 at a certain angle relative to itself, or the position indication line of the controller 240 at the measured target.

[0062] In actual use, there are two ways of use. One way of use is shown in Figures 6 and 7. Without the first measured object 910 as a reference, the laser reference line 231 is used to dynamically indicate the current rotation angle and rotation direction in cooperation with the laser target indicator line 232, wherein the laser reference line 231 is the 0° position indicator line of the device, that is, the 0° position indicator line of the arbitrary plane angle measurement laser ranging device 100. In use, usually before each measurement or during the measurement, the arbitrary plane angle measurement laser ranging device 100 or its arbitrary plane angle measurement laser ranging module 200 needs to be calibrated and zeroed to adapt the current plane parameters so that the starting position is the zero point position of the measurement. After rotating to a certain angle relative to itself, the arbitrary plane angle measurement laser ranging device 100 can display the angle value relative to the zero point position, that is, the measured angle β, through the display module 400. The arbitrary plane angle measurement laser ranging device 100 can also use the rotation angle of the laser emitted by itself relative to a certain reference orientation to measure its own relative rotation angle at different times or points, and with the display animation and indicator line laser, it can realize the angle measurement of any position of any inclined plane.

[0063] Another use method is shown in FIG. 13 and FIG. 14 , using the first measured object 910 as a reference, and also dynamically indicating the current rotation angle and rotation direction through the laser reference line 231 and the laser target indication line 232. Similarly, the laser reference line 231 is the 0° position indication line of the device, that is, the 0° position indication line of the arbitrary plane angle measurement laser ranging device 100. In use, usually before each measurement or during the measurement, the arbitrary plane angle measurement laser ranging device 100 needs to be calibrated and zeroed to adapt to the current first measured object 910, so that the initial placement position is the zero point position of the measurement. When the arbitrary plane angle measurement laser ranging device 100 is placed on the second measured object 920, the arbitrary plane angle measurement laser ranging device 100 displays the angle value relative to the zero point position of the first measured object 910, and the angle value is also the angle between the first measured object 910 and the second measured object 920, that is, the measurement angle β. Similarly, the arbitrary plane angle measurement laser distance measuring device 100 can also use the laser emitted by itself to measure the angle between any two or more objects on the same plane, and cooperate with the display animation and the indicator line laser to achieve the angle measurement between any two or more objects on the same plane. The rest of the embodiments are similar and will not be described in detail.

[0064] It should be noted that other embodiments of the present application also include any plane angle measurement laser ranging module and device that can be implemented and formed by combining the technical features in the above embodiments.

[0065] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
