Description

Technical Field

[0001] The utility model relates to the field of algorithm test supporting adjustment table structures, and particularly relates to a supporting laser collimation mechanical adjustment table and a target paper for invisible laser vision algorithm tests. Background Art

[0002] Today, with the rapid development of technology, lasers have been applied in all aspects of life, such as in automated devices like elevators, turnstiles, and assembly lines. From these devices, it can be seen that the distance between the transmitting end and the receiving end is relatively close, which is a short-distance detection method. Due to the non-visual nature of invisible lasers, as well as the combined effects of mechanical structure processing errors, internal laser processing errors, and assembly errors, under the condition of medium-distance transmission, coupled with the relatively low power of ordinary lasers, the laser detection method cannot meet the functional tasks of medium-distance detection. The most important reason is that invisible light cannot accurately align with the target position, enabling relevant detection algorithms to be successfully completed. Therefore, the design of a supporting laser collimation mechanical adjustment table for medium-distance invisible laser vision algorithm tests is extremely urgent. Summary of the Utility Model

Detailed implementation mode

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] It should be noted that all directional indications (such as up, down, left, right, front, back,...) in the embodiments of the present invention are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0041] The present invention discloses a supporting laser collimation mechanical adjustment table for invisible laser vision algorithm testing. In terms of area division, it can be divided into three parts, including: an adjustment part 100, a fixed part 200, and a base part 300 (as Figure 1 shown).

[0042] Among them, the adjustment part 100, as the main functional implementation structure of the adjustment table, includes an invisible light component 1000, an active translation component 2000, and an active rotation component 3000 (as Figure 2 shown). The fixed part 200 is composed of a visible laser emitter 14, a laser emitter fixture 13, which serves as a calibration reference, and an invisible laser emitter to be replaced during subsequent multi-channel laser detection (as Figure 3 shown). The base part 300 is the stable part of the overall debugging table. Since the base part 300 is directly or indirectly connected to the ground, it ensures the knowability of the laser emission data in space, and it includes a frame component.

[0043] Among them, the frame assembly, the frame assembly 5000, is composed of frame struts 4, a coarse adjustment base 15 and a level 16. The overall data knowability is ensured by the level, and the laser collimation center can be coarsely adjusted through the coarse adjustment base so as to perform precise adjustment by using the translation knob and the rotation knob subsequently.

[0044] The rotation active assembly 3000, also known as the multi-component base assembly, is mainly composed of a rotation base 10, a Y-axis positive direction rotation knob 9a, an X-axis negative direction rotation knob 9b, a Y-axis negative direction rotation knob 9c and an X-axis positive direction rotation knob 9d. It is the active assembly for realizing the rotation function and controls the rotation of the rotation driven assembly. For the visible light laser emitter assembly 4000, it serves as the carrier for bearing all fixed functions and has very important functional attributes. Among them, the rotation base 10 is fixedly arranged on the frame assembly. It has a through hole arranged in a penetrating manner, and a plurality of rotation knobs are arranged in the circumferential direction of the through hole. The rotation knobs 9 include a Y-axis negative direction rotation knob 9c, a Y-axis positive direction rotation knob 9a, an X-axis negative direction rotation knob 9b and an X-axis positive direction rotation knob 9d arranged on the upper, lower, left and right of the through hole.

[0045] The translation base 3 has a square space and is arranged at the front end of the rotation base 10. A plurality of tension springs are arranged between the rear side of the translation base 3 and the rotation base 10. And the rear side of the translation base 3 is provided with positioning holes adapted to the rotation knobs. An active translation knob is arranged above and on any one side of the left and right of the translation base 3. The active translation knobs include an X-axis active translation knob 12 and a Y-axis active translation knob 5. Guide grooves are arranged in the X direction and the Y direction of the translation base 3. The X-axis active translation knob 12 and the Y-axis active translation knob 5 are respectively placed in the guide grooves, and the X-axis active translation knob 12 and the Y-axis active translation knob 5 respectively form a screw drive fit with the driven translation clamp.

[0046] A translation support column 6 for guiding is arranged on one side of the X-axis active translation knob 12 and the Y-axis active translation knob 5.

[0047] The driven translation clamp can be slidably arranged in the square space. It can move relative to the X-axis or Y-axis direction driven by the active translation knob. The driven translation clamp includes a driven translation clamp upper cover 20 and a driven translation clamp lower cover 17 which are locked to each other, and a clamping port for clamping the invisible laser emitter 1 is formed between the two. It is ensured that the clamped invisible laser emitter will not generate mechanical errors caused by crosstalk or the like.

[0048] The invisible laser emitter 1 is fixed by the driven translation fixture and is placed on the central axis of the through hole. The driven translation fixture is used to fix the invisible laser emitter 1, mainly serving as a driven component in the realization of the translation function to ensure that the clamped invisible laser emitter does not have mechanical errors such as crosstalk.

[0049] The laser emitter fixture 13 is fixedly arranged at the bottom of the rotating base 10.

[0050] The visible light laser emitter 14 is detachably connected to the laser emitter fixture 13, and the optical path of the visible light laser emitter 14 is located directly below the optical path of the invisible laser emitter 1.

[0051] The frame assembly includes a rough adjustment base 15 and two frame struts 4 fixedly arranged above it, and the rotating base 10 is arranged between the two frame struts 4. A spirit level 16 is provided on the rough adjustment base 15. The rough adjustment base 15 is also provided with a dividing plate.

[0052] The invisible light component 1000 is a driven component for realizing the translation function, ensuring that the clamped invisible laser emitter does not generate mechanical errors caused by crosstalk, etc.; while the translation active component 2000 is the active component for realizing the translation function, and since it is also the driven component for realizing the rotation function, it can also be called the rotation driven component; the rotation active component 3000 plays the role of a driven component in the realization of the rotation function, and can also be called the multi-component base component, undertaking multiple responsibilities in the present invention.

[0053] The invisible light component 1000 is composed of a driven translation fixture clamping the invisible laser emitter 1. The driven translation fixture can be divided into a driven translation fixture upper cover 2 and a driven translation fixture lower cover 16. After the driven translation fixture upper cover 2 and the driven translation fixture lower cover 16 clamp the invisible laser emitter 1, they are fixed with bolts (as Figure 3 shown), ensuring the stability of the invisible laser emitter.

[0054] The main component of the translation active component 2000 is the translation base 3. This part not only has holes drilled for realizing the translation functions of the X-axis and Y-axis, but also has guide grooves tapped for realizing the rotation function. Therefore, this component can also be called the rotation driven component. From above, the Y-axis active translation knob 5 and the translation strut 6 are passed through above the invisible light component, and the holes are sealed with nuts and the translation cover 7. When the X-axis active translation knob 12 rotates, the invisible light component 1000 can be translated in the X-axis direction. Clockwise rotation is for right translation in the negative X-axis direction, and counterclockwise rotation is for left translation in the positive X-axis direction; when the Y-axis active translation knob 5 rotates, the invisible light component 1000 can be translated in the Y-axis direction. Clockwise rotation is for rising in the positive Y-axis direction, and counterclockwise rotation is for descending in the negative Y-axis direction (asFigure 3 As shown). The groove on the translation base 3 can be viewed corresponding to the dial on the lower coarse adjustment base 15 to obtain the offset angle between the invisible laser emitter 1 and the visible laser emitter 14.

[0055] The rotation active component 3000 mainly consists of a rotation base 10, four rotation knobs 9 and four knob caps 11, and is connected to the rotation driven component by a tension spring. When the tension spring is not stressed, it is a weak connection. However, when the tension spring is stressed, the pulling forces given by the four tension springs and the pushing forces of the four rotation knobs 9 will form a force balance, thus forming a strong connection state (as Figure 3 shown). When the rotation knob 9a in the positive Y-axis direction rotates, the rotation driven component drives the invisible light component 1000 to rotate around the X-axis. Clockwise rotation is upward in the positive Y-axis direction, and counterclockwise rotation is downward in the negative Y-axis direction. When the rotation knob 9b in the negative X-axis direction rotates, the rotation driven component drives the invisible light component 1000 to rotate around the Y-axis. Clockwise rotation is to the right in the negative X-axis direction, and counterclockwise rotation is to the left in the positive X-axis direction. When the rotation knob 9c in the negative Y-axis direction rotates, the rotation driven component drives the invisible light component 1000 to rotate around the X-axis. Clockwise rotation is downward in the negative Y-axis direction, and counterclockwise rotation is upward in the positive Y-axis direction. When the rotation knob 9d in the positive X-axis direction rotates, the rotation driven component drives the invisible light component to rotate around the Y-axis. Clockwise rotation is to the left in the positive X-axis direction, and counterclockwise rotation is to the left in the negative X-axis direction (as Figure 4 shown).

[0056] The translation base 3 is connected to the rotation base 10 through at least three rotation knobs 9 (rotation knob 9a in the positive Y-axis direction, rotation knob 9b in the negative X-axis direction, and rotation knob 9d in the positive X-axis direction). Since the rotation knob 9 is a common part bolt, this connection is a firm connection. Therefore, the rotation active component 3000 can also be called a multi-component base component. For the extensibility of subsequent multi-channel detection algorithm tests, the laser emitter fixture 13 and the visible laser emitter 14 are only connected by an interference fit, increasing the possibility of replacing the invisible laser emitter while ensuring stable clamping.

[0057] The base part 300 is the stable part of the overall debugging platform. Since the base part 300 is directly or indirectly connected to the ground, it ensures the knowability of the laser emission data in space. It mainly consists of two frame struts 4, a coarse adjustment base 15, and a level gauge (as Figure 3As shown). The two frame pillars 4 are fixedly connected to the rotating base 10 on both sides with bolts, and are also fixedly connected to the coarse adjustment base 15. The level 16 is inserted into the hole reserved in the middle of the coarse adjustment base 15 to facilitate the angle of deviation in the vertical direction. The indexing plate left on the coarse adjustment base 15 by laser marking technology can not only be manually adjusted in the early stage of adjusting the laser transmitter center, and the calibrated visible laser transmitter center is marked to the ideal position, but also the angle of deviation of the laser light path in the horizontal direction can be read on it.

[0058] At the same time, the utility model also discloses a target paper of a matching laser collimator mechanical adjustment table for the invisible laser vision algorithm test, and the target paper can be replaced according to demand.

[0059] It includes:

[0060] A first target, used for positioning laser light emitted by an invisible laser emitter;

[0061] A second target, used for positioning the laser emitted by the visible light laser transmitter, wherein the bull's eye of the second target and the bull's eye of the first target are located on the same longitudinal center line;

[0062] The positioning scale is arranged on one side of the first target and the second target.

[0063] The height of the bull's eye of the first target and the distance between the bull's eye of the second target and the bull's eye of the first target can be set as needed to meet different test requirements.

[0064] In this embodiment, the horizontal deviation angle of the laser light path is read, and finally the laser height, the distance between the visible laser emitter 14 and the bottom surface is 50 mm, the distance between the invisible laser emitter 1 and the visible laser emitter 14 is 60 mm, and the distance from the laser emitter to the laser reflection detection area (such as Figure 6 Calculate the required values such as the offset distance by using the distance and other data shown in the figure α , plays a role in grasping the overall optical path (such as Figure 5 At the same time, the reason why the two frame pillars 4 are not designed to be installed on the symmetry axis is that the upper two frame pillars 4 are not installed in the middle part of the adjustment part 100, that is, the center of gravity of the part other than the coarse adjustment base 15 in the present design structure is not in the plane formed by the two frame pillars 4, but in the front side. Therefore, the installation positions of the two frame pillars 4 are moved backward to ensure that the center of gravity is at the center position of the coarse adjustment base 15, so as to prevent the error in adjustment and overturning caused by excessive torque due to the forward movement of the center of gravity.

[0065] The supporting laser collimation mechanical adjustment table designed for the invisible laser vision algorithm test in this application can not only address all invisible laser adjustment problems from medium distance to short distance, but also be used for different conditions of single-channel or multi-channel (two-channel) invisible laser vision algorithm tests. It is easy to operate. Users can customize fixtures with different installation apertures according to the laser emitter hardware they choose to handle various different algorithm test situations.

[0066] Example 1 (taking the laser emitter of Yaocheng Technology as an example)

[0067] Since the laser collimation emitted by the invisible laser generator cannot be accurately emitted to the predetermined position, a lot of time is wasted in the medium-distance test by searching for the collimation irregularly many times. However, this adjustment table can effectively and regularly limit the laser emission position, reduce the error caused by the machine, and visually adjust it to the specified position by adjustment. At the same time, the approximate quantitative error angle size can be obtained by reading the relevant data on the adjustment table.

[0068] As Figure 7 shown, the specific test steps are as follows:

[0069] S1: Install an invisible laser emitter (performance parameters: 980nm, 500mw, 20*60mm) on the upper invisible light component 1000 and install a visible laser emitter (performance parameters: 635nm, 185mw, 20*60mm) on the lower visible light laser transmitter component 4000 for calibration.

[0070] S2: Rotate all the rotation knobs 9 of this adjustment table to the relaxed state and place it on the moving plane.

[0071] S3: Paste a calibrated target paper printed in equal proportion on the laser reflection detection area opposite to the laser adjustment table and turn on the observation camera.

[0072] S4: Place the moving plane at a position 5m away from the laser reflection detection area.

[0073] S5: Coarsely adjust vertically by raising or lowering the moving plane, and rotate the coarse adjustment base 15 to coarsely adjust horizontally to ensure that the collimation position of the visible laser emitter 14 is at the center of the target ring below the calibrated target paper.

[0074] S6: Subsequently, observe the invisible light position through the camera. In this case, the invisible light will not deviate too much. The collimation position of the invisible laser emitter 1 can be adjusted by rotating the Y-axis translation knob 5, the X-axis translation knob 12, and the rotation knob to make its collimation position at the center of the target ring above the calibrated target paper.

[0075] S7: Place the moving plane at distances of 25m, 50m, 75m, ……, the target distance from the laser reflection detection area respectively, and repeat the operations in S5 to S6 to ensure that the aiming position of the invisible laser emitter 1 can finally be accurately detected. At this time, the single-channel laser vision algorithm test can be carried out.

[0076] S9: After the single-channel test is completed, replace the visible laser emitter 14 with an invisible laser emitter, and thus the multi-channel laser vision algorithm test can be carried out.

[0077] Note: During the entire adjustment process, directly touching the invisible light component 1000, the translation active component 2000, and the rotation active component 3000 is prohibited. Only rely on the rotation of the knob for adjustment to avoid causing other errors.

[0078] It can be seen from the adjustment results that this adjustment table can effectively adjust the invisible light optical path in the medium-distance case, and because the base is directly or indirectly connected to the ground, the optical path is stable and does not shake, which is convenient for the development of the algorithm test.

[0079] The embodiments should not be regarded as limitations of the present invention, but any improvements made based on the spirit of the present invention should be within the protection scope of the present invention.
