Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.

The disclosure provides a distance measuring method applied to distance measuring equipment. According to the ranging method, the range finder can be arranged on a rotating platform of the supporting device, the supporting device can control the rotating platform to rotate relative to a base of the supporting device according to a received rotation control instruction, and further rotation of the range finder relative to the base is achieved, so that 360-degree omnibearing ranging can be achieved, and a 2D model of a target to be measured can be conveniently established according to ranging data. Moreover, the ranging method does not need to use a heavy professional laser scanning modeling instrument, is convenient to carry, and further improves the convenience of ranging.

In one exemplary embodiment, a ranging method is provided, which is applied to a ranging apparatus. Referring to fig. 1 and 7, the ranging method may include:

s110, receiving a ranging control instruction sent by a terminal;

s120, controlling the distance measuring instrument to measure the distance according to the distance measuring control command;

s130, feeding ranging data back to the terminal;

s140, receiving a rotation control instruction sent by a terminal;

s150, controlling the rotary platform to rotate by a second preset angle relative to the base according to the rotation control instruction;

and S160, feeding back the rotation information to the terminal.

In step S110, the ranging apparatus may include a supporting device and a range finder.

For example, referring to figures 2 and 3, the support means is used to position the rangefinder 12 to form a rangefinder apparatus. Wherein the support means may comprise a base 111 and a rotatable platform 112, the rangefinder 12 being mounted to the rotatable platform 112 to form a complete rangefinder apparatus.

In the step, the distance measurement control command is sent by the terminal in response to the fact that the accumulated angle is smaller than or equal to a first preset angle, and the accumulated angle is an accumulated value of the rotation angle of the rotary platform relative to the base in the current distance measurement process.

The first preset angle can be determined according to actual measurement conditions. For example, when 2D modeling of an indoor space is required, the first preset angle may be 360 °.

In this step, the electrical connection between the terminal and the ranging apparatus may be established first to perform the current ranging. Since the terminal has just established an electrical connection with the ranging apparatus, the terminal has not yet controlled the rotation of the rotary platform, i.e., the terminal can determine that the cumulative value of the rotation angles of the rotary platform with respect to the base is 0 °, which is smaller than the first preset angle (360 °). And the terminal responds to the condition that the accumulated angle is smaller than the first preset angle, generates a distance measurement control instruction and sends the distance measurement control instruction to the distance measurement equipment.

In step S120, as shown with reference to fig. 2 and 3, the supporting device may include a control device 113, and the control device 113 may be electrically connected with the distance meter 12. The control device 113 may receive a ranging control command transmitted from the terminal, and generate a ranging command in response to the received ranging control command, and then transmit the ranging command to the rangefinder 12. After receiving the ranging command, the rangefinder 12 may perform measurements in response to the ranging command.

Of course, the range finder 12 may also be directly electrically connected to the terminal (e.g., via a wireless network connection or via a local area network connection, etc.), and the range finder 12 may directly receive the range control command sent by the terminal and perform measurement in response to the received range control command to generate the range data.

In step S130, the ranging data is data measured by the range finder in response to the ranging control command. Namely, the distance measuring instrument generates the distance measuring data through measurement, and then the distance measuring data can be fed back to the terminal.

In step S140, a rotation control command is transmitted by the terminal in response to receiving the ranging data. After the terminal receives the ranging data, a rotation control command can be generated and sent to the supporting device.

For example, as shown with reference to fig. 2 and 3, the supporting means may comprise a control means 113 and a drive means 114. The rotary platform 112 is rotatably connected to the base 111 via a driving device 114, that is, the driving device 114 can drive the rotary platform 112 to rotate relative to the base 111.

The control device 113 may be electrically connected to the driving device 114. The control device 113 may receive the rotation control command transmitted from the terminal, and generate a rotation command in response to the received rotation control command, and then transmit the rotation command to the driving device 114. After receiving the rotation command, the driving device 114 drives the rotation platform 112 to rotate relative to the base 111 in response to the rotation command, so as to drive the range finder 12 to rotate relative to the base 111.

The angle of the single rotation can be preset in advance, and the angle of the single rotation is recorded as a preset angle. That is, the control device 113 generates a rotation command every time it receives a rotation control command, and then sends the rotation command to the drive device 114. The driving device 114 can drive the rotating platform 112 to rotate by a predetermined angle (e.g., 5 ° or 10 °) relative to the base 111 based on the received rotating command.

The control device 113 may be a control motherboard, and the driving device 114 may include a driving motor 1142 and a motor driving board 1141. The control motherboard may receive the rotation control command, generate a rotation command, and then send the rotation command to the motor drive plate 1141. After receiving the rotation command, the motor driving board 1141 may drive the motor shaft of the driving motor 1142 to rotate in response to the rotation command, and the driving motor 1142 may drive the rotating platform 112 to rotate relative to the base 111, thereby driving the range finder 12 to rotate relative to the base 111 by a preset angle.

In step S150, after the control device of the distance measuring apparatus receives the rotation control command, the rotation platform may be controlled to rotate by a second preset angle relative to the base based on the rotation control command. The rotation control command may include a second preset angle, and the second preset angle is an angle preset in advance by the terminal.

For example, the terminal is installed with an application program for controlling ranging, in which the second preset angle may be preset in advance to 10 °. Therefore, after the ranging device receives the rotation control command every time, the rotating platform can be controlled to rotate 10 degrees relative to the base according to the second preset angle included by the rotation control command.

Wherein the rotation control command may be received by a control device of the distance measuring apparatus. The control device can generate a rotation command according to the rotation control command and send the rotation command to a motor driving plate of the distance measuring equipment. The motor drive board is based on the rotation instruction, and the motor shaft of the step motor of drive range unit drives rotary platform and rotates the second and predetermine the angle, and rotary platform alright drive the distancer and rotate the second and predetermine the angle.

In step S160, the rotation information indicates that the rotating platform rotates by a second preset angle relative to the base. After rotary platform has rotated the second and has predetermine the angle relative to the base, alright generate rotatory information, then with rotatory information transmission to terminal.

In the method, after the terminal and the ranging device are electrically connected, the terminal does not control the rotation of the rotating platform of the ranging device, that is, the terminal can determine that the cumulative value of the rotation angle of the rotating platform relative to the base is 0 degrees and is smaller than a first preset angle (for example, 360 degrees), and then the terminal can send a ranging control instruction to the ranging device.

After the rotating platform rotates by the second preset angle each time, the ranging device generates rotating information and sends the rotating information to the terminal. The terminal judges the current accumulated rotating angle of the rotating platform according to the received rotating information, records the current accumulated rotating angle as an accumulated angle, and generates a ranging control instruction again when the accumulated angle is still smaller than a first preset angle, and sends the ranging control instruction to ranging equipment so as to control the range finder to continue ranging.

And circulating the steps until the accumulated rotation angle of the rotating platform reaches the first preset angle, and finishing the distance measurement without continuing the measurement after the measurement is finished.

The distance measurement method can automatically realize omnibearing distance measurement so as to better measure various special-shaped rooms, is convenient for a terminal to carry out 2D modeling of a special-shaped room plan according to all distance measurement data, and the distance measurement equipment used by the distance measurement method is simple in structure and convenient to carry, so that the convenience of distance measurement is further improved.

In one exemplary embodiment, a ranging method is provided, which is applied to a ranging apparatus. Referring to fig. 2 and 3, in the ranging apparatus used in the ranging method, the base 111 of the supporting device may include a mounting chamber 1111, and a mounting structure 115 (e.g., a mounting bracket) is disposed in the mounting chamber 1111. Wherein, the mounting structure 115 is fixedly connected with the base 111. For example, the mounting structure 115 may be welded, adhesively attached, etc. to the inner wall of the base 111.

The control device 113 may be welded, adhesively attached to the mounting structure 115, or fixedly attached to the mounting structure 115 by fasteners such as screws or bolts.

The counterweight structure 117 is connected to the rotating platform 112, wherein the counterweight structure 117 and the rotating platform 112 may be an integrally formed structure, and the counterweight structure 117 may also be connected to the rotating platform 112 by welding, bonding, clamping, or fastening.

Wherein the counterweight structure 117 is located at an end of the rotating platform 112 remote from the rangefinder 12. The counterweight structure 117 may be used to balance the weight of the rangefinder 12 on the rotating platform 112, preventing the support means from tilting, ensuring proper use of the rangefinder apparatus.

When the driving device 114 includes the driving motor 1142, a motor shaft of the driving motor 1142 can pass through the shaft hole of the base 111 to connect with the rotating platform 112, and the driving motor 1142 drives the rotating platform 112 to rotate through the motor shaft. That is, the base 111 is rotatably connected to the rotary platform 112 by a motor shaft. In this case, the weight structure 117 and the distance measuring instrument 12 may be respectively disposed at both sides of the motor shaft to balance the distance measuring instrument 12 at the second side of the motor shaft through the weight structure 117 at the first side of the motor shaft, so as to prevent the rotation platform 112 from being inclined, thereby ensuring the normal use of the distance measuring apparatus.

Wherein, the counterweight structure 117 and the distance measuring instrument 12 can be respectively located at two sides of the rotating platform 112. For example, the counterweight structure 117 is located on a side of the rotating platform 112 close to the base 111, and the range finder 12 is located on a side of the rotating platform 112 far from the base 111. That is, when using this strutting arrangement, distancer 12 is located the upside of rotary platform 112, and counter weight structure 117 is located the downside of rotary platform 112 to avoid counter weight structure 117 to influence the use of whole range finding equipment, further promoted and used the experience.

For example, the distance meter 12 may be fixed to the mounting groove by four fastening bolts to better ensure that the distance meter 12 is reliably mounted on the rotating platform 112, thereby ensuring the reliability of the measured data.

Meanwhile, the emission end surface of the distance meter 12 is flush with the bottom surface of the mounting groove 1121, so that the reliability of the measurement data of the distance meter 12 can be ensured as long as the rotating platform 112 is ensured to be in a horizontal state.

Wherein the rotating platform 112 may further be provided with a first level 118 and/or a second level 119. Wherein, the first level 118 and the second level 119 can both adopt bubble levels.

In one exemplary embodiment, a method for controlling ranging is provided and applied to a terminal. Referring to fig. 4 and 7, the method of controlling ranging may include:

s220, receiving ranging data fed back by the ranging equipment;

s230, responding to the received ranging data, and sending a rotation control command to the ranging equipment;

and S240, receiving the rotation information fed back by the ranging device.

In step S210, the ranging control command is used to control a range finder of a ranging apparatus to perform ranging. The accumulated angle is the accumulated value of the rotation angle of the rotating platform of the distance measuring equipment relative to the base of the distance measuring equipment in the current distance measuring process.

In this step, when the terminal determines that the accumulated angle is less than or equal to the first preset angle, a ranging control command may be generated and sent to the ranging device. For example, the terminal may send a ranging control command to a rangefinder of the rangefinder apparatus to control the rangefinder to measure.
