Description

Technical Field

[0001] This utility model relates to the field of attitude adjustment of optoelectronic devices, specifically to a portable optoelectronic device and an optoelectronic measurement system. Background Technology

[0002] With the development of optoelectronic technology, portable optoelectronic devices are being used more and more widely. Portable optoelectronic devices have the advantages of being lightweight, easy to carry, and quick to assemble and disassemble, and are widely used in security monitoring, observation and early warning in bases and important locations, as well as target guidance or target calculation in fire control systems.

[0003] Portable optoelectronic equipment is typically transported in a carrying bag or box, and then quickly set up on a tripod at the test site. Due to the harsh outdoor installation environment, with uneven ground such as cement, hills, sand, and mud, the portable optoelectronic equipment may be uneven after the tripod is set up, resulting in inaccurate pointing or guidance. For example, radar guidance information (i.e., the target's azimuth and elevation angles) may not be accurately directed to the target; or the calculated latitude, longitude, and altitude (or azimuth and elevation angles) of the target may be inaccurate. Therefore, high requirements are placed on tripod leveling and rapid attitude calculation.

[0004] Tripod leveling method: Install a level bubble on the tripod and level it according to the position of the bubble deviation; the main problems of this method are: (1) the bubble accuracy is low, generally within 0.5°; (2) the size is large and it is not easy to integrate; (3) at the same time, the bubble data cannot communicate with portable optoelectronic devices. Utility Model Content

[0005] The purpose of this invention is to provide a portable optoelectronic device and optoelectronic measurement system to achieve rapid and precise leveling of the optoelectronic device.

[0006] To solve the above-mentioned technical problems, this utility model provides a portable optoelectronic device, which is mounted on an adjustable support and includes a two-axis turntable, an optoelectronic load, and an inclinometer. The optoelectronic load is connected to the mounting surface of the two-axis turntable, and the inclinometer is set inside the two-axis turntable. The measuring surface of the inclinometer is parallel to the mounting surface of the two-axis turntable, and the pitch measuring direction of the inclinometer is parallel to the measuring optical axis of the optoelectronic load.

[0007] When the portable photoelectric device is leveled, the inclinometer rotates horizontally with the two-axis turntable, so that the measuring direction of the inclinometer is the same as or opposite to the adjustment directions of the adjustable support.

[0008] According to the above scheme, the two-axis turntable is a two-axis servo turntable.

[0009] According to the above scheme, the photoelectric load is a visible light load, an infrared thermal imager, or a laser rangefinder.

[0010] According to the above scheme, the pitch angle measurement range of the inclinometer is ±90°, the roll angle measurement range is ±180°, the static measurement error is ≤0.1°, and the resolution is 0.01.

[0011] According to the above scheme, the inclinometer is equipped with a serial port for outputting pitch and roll angles.

[0012] This utility model also provides a photoelectric measurement system, including a portable photoelectric device and an adjustable support, wherein the portable photoelectric device is fixed on the adjustable support; wherein the portable photoelectric device includes a two-axis turntable, a photoelectric load, and an inclinometer; the photoelectric load is connected to the mounting surface of the two-axis turntable, the inclinometer is set inside the two-axis turntable, and the measuring surface of the inclinometer is parallel to the mounting surface of the two-axis turntable, and the pitch measuring direction of the inclinometer is parallel to the measuring optical axis of the photoelectric load;

[0013] When the portable photoelectric device is leveled, the inclinometer rotates horizontally with the two-axis turntable, so that the measuring direction of the inclinometer is the same as or opposite to the adjustment directions of the adjustable support.

[0014] According to the above scheme, the two-axis turntable is a two-axis servo turntable.

[0015] According to the above scheme, the photoelectric load is a visible light load, an infrared thermal imager, or a laser rangefinder.

[0017] According to the above scheme, the adjustable support is a tripod.

[0018] Beneficial effects

[0019] This invention utilizes the small size and easy integration of an inclinometer to reduce the dimensions of portable optoelectronic devices. Furthermore, the inclinometer used offers superior measurement accuracy compared to existing bubble levels, providing a data foundation for precise leveling of optoelectronic loads. During leveling of the portable optoelectronic device, rotating the two-axis turntable allows the inclinometer's measurement direction to be aligned with or opposite to the adjustment direction of the adjustable support. This enables the rapid reading of the tilt angle in the direction most sensitive to the adjustable support's adjustment, thus improving leveling efficiency.

[0020] Furthermore, by utilizing the output serial port of the inclinometer, real-time transmission and processing of measurement data can be achieved, facilitating communication and data analysis with other devices, thereby improving the overall performance and intelligence level of the device and enhancing leveling efficiency.

[0032] It should be noted that when the inclinometer 2 is installed in the two-axis rotary table, it is necessary to ensure that the inclinometer 2 and the mounting surface of the two-axis rotary table are tightly fitted, parallel, and stable. See [link to relevant documentation]. Figure 3If there is an installation angle between the mounting surface and the mounting surface, the measurement results will be inaccurate. See [link / reference]. Figure 2 .

[0033] Furthermore, the two-axis turntable 1 is a two-axis servo turntable.

[0034] Furthermore, the photoelectric load 3 is a visible light load, an infrared thermal imager, or a laser rangefinder.

[0035] Furthermore, the pitch angle measurement range of the inclinometer 2 is ±90°, the roll angle measurement range is ±180°, the static measurement error is ≤0.1°, and the resolution is 0.01.

[0036] Furthermore, the inclinometer 2 is equipped with a serial port for outputting pitch and roll angles.

[0037] Example 2:

[0038] See Figure 1 , Figure 4 This embodiment discloses a photoelectric measurement system, including a portable photoelectric device 5 and an adjustable support. The portable photoelectric device is fixed on the adjustable support. The portable photoelectric device 5 includes a two-axis turntable 1, a photoelectric load 3, and an inclinometer 2. The photoelectric load 3 is connected to the mounting surface of the two-axis turntable 1. The inclinometer 2 is set inside the two-axis turntable 1, and the measuring surface of the inclinometer 2 is parallel to the mounting surface of the two-axis turntable 1. The pitch measuring direction of the inclinometer 2 is parallel to the measuring optical axis of the photoelectric load 3.

[0039] When the portable photoelectric device is leveled, the inclinometer rotates horizontally with the two-axis turntable, so that the measuring direction of the inclinometer is the same as or opposite to the adjustment directions of the adjustable support.

[0043] Furthermore, the adjustable support is a tripod 4.

[0044] Example 3:

[0045] Based on the photoelectric measurement system described in Embodiment 2, this embodiment provides a leveling method for the photoelectric load 3 within the photoelectric measurement system, including:

[0046] S1. Rotate the orientation motor of the two-axis servo turntable one revolution, and sequentially read the pitch angle of each leg of the tripod 4 and the inclinometer 2 in the direction directly opposite each leg (see...). Figure 5 The azimuth angles in the six directions can be expressed as follows: , Figure 5 The solid arrow indicates the direction of tripod 4, and the dashed arrow indicates the direction directly facing tripod 4.

[0047] S2. Adjust the height of the foot corresponding to the maximum pitch angle to reduce the pitch angle in the corresponding direction;

[0048] S3. Repeat S1~S3 until the maximum pitch angle is lower than the set threshold.

[0049] See Figure 6 When the measured maximum pitch angle (i.e., the pitch angle of the tripod mounting surface 4) is (Right now Then the portable optoelectronic device 5 is at an azimuth angle of 5. At that time, pitch angle and roll angle With azimuth The relationship satisfies:

[0050]

[0051]

[0052] Azimuth Projection angle on the horizontal plane satisfy:

When the maximum pitch angle is not greater than a set threshold (i.e.... When the angle is ≤2°, the installation error of the portable optoelectronic device 5 is obtained; the installation error is used to compensate for the pitch attitude of the portable optoelectronic device 5.

[0061] It should be noted that the maximum pitch angle According to the pitch angle measurement value obtained by the inclinometer 2 described in Embodiment 1, the inclinometer 2 can output the pitch angle measurement value via serial port or display the pitch angle measurement value on a screen; azimuth angle The installation error can be obtained by reading the rotation angle of the horizontal motor in the two-axis servo turntable; the installation error can be calculated by a computer device independent of the portable optoelectronic device 5, and the computer device corrects the measurement results of the optoelectronic load 3 according to the installation error.
