Detailed Description

For cameras such as a 2D camera, a 3D camera, and a depth camera, the camera includes a camera body and a lens for imaging an image on an image sensor of the camera body, so that an image of a laser line emitted from the camera is recorded while the laser line scans a surface of a photographed object. In order to ensure the accuracy of the acquired image, it is necessary to ensure that the performance of the lens meets the requirements. Therefore, before assembling the lens with the camera body, it is necessary to test the lens to determine whether the lens parameters are acceptable.

In the related art, a lens to be tested is mounted on a test camera body, and a camera is manually aligned to a marker and shoots the marker, so that measurement of lens parameters is realized. However, during the testing process, problems such as lens shake, non-perpendicular lens axis and marker plane occur, thereby reducing the accuracy of the measured lens parameters.

In view of this, the present disclosure provides a testing device, which not only can fix a lens to be tested so as to avoid shaking the lens to be tested and further improve accuracy of measured lens parameters, but also can adjust a posture of the lens to be tested relative to a calibration area, for example, make an axis of the lens to be tested perpendicular to the calibration area, so as to achieve accurate measurement of parameters of the lens to be tested.

The test device provided by the embodiment of the present disclosure is described in detail below with reference to the accompanying drawings.

Fig. 1 is a schematic perspective view of a testing device according to an embodiment of the disclosure. Referring to fig. 1, the test apparatus provided in the present disclosure includes a moving part 100 and a rotating part 200. The rotating member 200 is disposed on the moving member 100, and the rotating member 200 is used for fixing the lens 800 to be tested. When the lens 800 to be tested is tested, the calibration area is arranged at intervals from the lens 800 to be tested along the first direction, the moving component 100 is used for enabling the lens 800 to be tested to move along at least one direction of the first direction and the second direction relative to the calibration area, and the rotating component 200 is used for enabling the lens 800 to be tested to rotate by a preset angle relative to the calibration area around a rotating axis parallel to the third direction. Any two directions of the first direction (such as the X direction in fig. 1), the second direction (such as the Y direction in fig. 1) and the third direction (such as the Z direction in fig. 1) intersect and do not coincide.

Wherein, the interrelationship among the first direction, the second direction and the third direction is not limited herein. For example, the first direction and the second direction are perpendicular, and the first direction and the second direction are not perpendicular to the third direction. Or the first direction, the second direction and the third direction are perpendicular to each other. In the embodiment of the present disclosure, the movement of the lens 800 to be tested with respect to the calibration area is described by taking the example that the first direction, the second direction and the third direction are perpendicular to each other.

In the process of testing the lens 800 to be tested, the moving component 100 moves the lens 800 to be tested along the first direction relative to the calibration area, so that the height of the lens 800 to be tested relative to the calibration area can be adjusted, and the test requirement can be met. In addition, the lens 800 to be tested is moved along the second direction relative to the calibration area by the moving component 100, so that the position of the lens 800 to be tested along the second direction relative to the calibration area can be adjusted, so that the drawing of the lens 800 to be tested covers the calibration area, and the test requirement is met. In addition, the rotation member 200 rotates the lens 800 to be tested by a preset angle around the rotation axis, so that the axis of the lens 800 to be tested is perpendicular to the calibration area, and the testing requirement is met.

In the process of testing the lens 800 to be tested, whether the lens 800 to be tested moves in the first direction or the second direction or rotates around the rotation axis may be determined according to the state of the lens 800 to be tested relative to the calibration area, and thus, in the embodiment of the present disclosure, no particular limitation is imposed.

In summary, in the testing device provided by the embodiment of the present disclosure, the moving component 100 moves the lens 800 to be tested along at least one of the first direction and the second direction, and the rotating component 200 rotates the lens 800 to be tested by a preset angle around the rotation axis, so that the posture of the lens 800 to be tested relative to the calibration area can meet the requirements, thereby accurately measuring the lens parameters, and further, the lens 800 to be tested can be prevented from shaking, thereby improving the accuracy of the measured lens parameters.

Fig. 2 is a schematic perspective view of a portion of the test device of fig. 1. In the embodiment of the present disclosure, referring to fig. 2, the moving part 100 includes a vertical member 110 and a lateral member 120, and the rotating part 200 is provided to the lateral member 120. Wherein one end of the upright 110 is connected to one end of the cross member 120. The vertical member 110 is used to move the cross member 120 along a first direction, so that the interval between the lenses 800 to be tested and the calibration area along the first direction is variable. The cross member 120 is used to move the rotating member 200 along the second direction, so that the distance between the lens 800 to be tested and the vertical member 110 along the second direction is variable.

Wherein the vertical member 110 and the lateral member 120 may be connected by welding, clamping, screwing, or the like. Illustratively, in the embodiment of the disclosure, the cross member 120 is screwed with the vertical member 110, so that not only can the cross member 120 be connected with the vertical member 110, but also the cross member 120 or the vertical member 110 can be detached for replacement or repair, thereby reducing the maintenance difficulty of the testing device.

In the embodiment of the present disclosure, the rotating member 200 is disposed on the cross member 120, so that not only the lens 800 to be tested can be moved in the second direction, but also the distance by which the rotating member 200 moves in the second direction can be reduced by using the feature that the cross member 120 partially covers the calibration area, thereby reducing the time for adjusting the position of the rotating member 200 in the second direction.

The moving component 100 of the testing device provided in the embodiment of the present disclosure is formed by the vertical piece 110 and the lateral piece 120, so that not only can the lens 800 to be tested move along at least one of the first direction and the second direction relative to the calibration area, but also the movement of the lens 800 to be tested along the first direction and the second direction can be decoupled, so that the lens 800 to be tested can move alone along the first direction or the second direction.

In the disclosed embodiment, with continued reference to fig. 2, the vertical member 110 includes a vertical beam member 111 and a moving member 112. Wherein the moving member 112 is detachably coupled to the vertical beam 111 and fixedly coupled to the transverse member 120. The moving member 112 is configured to move in a first direction, so that the lens 800 to be tested moves in the first direction relative to the calibration area.

The specific connection method between the movable member 112 and the vertical beam 111 is not limited herein, as long as the movable member 112 can be stopped at different positions of the vertical beam 111 along the first direction. In one embodiment, the moving member 112 is mounted on the vertical beam 111 in a threaded manner, and when the moving member 112 is in threaded connection with different positions of the vertical beam 111 along the first direction, the moving member 112 stays at the different positions of the vertical beam 111 along the first direction, so that the heights of the transverse members 120 along the first direction relative to the calibration area are different, and the heights of the lens 800 to be tested along the first direction relative to the calibration area are different. Or in one embodiment, the moving member 112 is slidably connected to the vertical beam 111, and a locking structure is disposed between the moving member 112 and the vertical beam 111, where the locking structure is used to lock the moving member 112 and the vertical beam 111, so that the moving member 112 stays at different positions of the vertical beam 111 along the first direction.

In the embodiment of the present disclosure, no limitation is made here as to the specific structure of the vertical beam 111. Illustratively, the vertical beams 111 may be formed by profiles that not only support the cross members 120, but also reduce the cost of the vertical members 110.

In the embodiment of the present disclosure, no limitation is made here as to the specific structure of the moving member 112. In one possible implementation, the moving member 112 is in a plate-like structure and is detachably connected to the vertical beam member 111. In one possible implementation, and with continued reference to FIG. 2, the displacement member 112 includes a base member 113, a moveable member 114, and a locking member 115, the base member 113 being removably coupled to the vertical beam member 111, the base member 113 being adapted to move relative to the vertical beam member 111 in a first direction. The movable member 114 is movably connected to the base member 113 and fixedly connected to the transverse member 120, and the movable member 114 is configured to move relative to the base member 113 in a first direction. The locking member 115 is used to restrict the movement of the movable member 114 relative to the base member 113 in the first direction so that the position of the movable member 114 on the base member 113 in the first direction is variable.

The connection manner of the base member 113 and the vertical beam member 111 may refer to the above description of the connection manner of the moving member 112 and the vertical beam member 111, and will not be described in detail herein. For example, in the disclosed embodiment, the base member 113 is threadably coupled to the vertical beam member 111 such that the base member 113 can be separated from the vertical beam member 111 such that the base member 113 is positioned at different locations of the vertical beam member 111 in the first direction.

In the embodiment of the present disclosure, the connection manner of the movable member 114 and the base member 113 is not limited herein. In one embodiment, the base member 113 is slidably coupled to the movable member 114, and the locking member 115 is configured to limit sliding movement of the movable member 114 relative to the base member 113. In one embodiment, the movable member 114 is movably coupled to the base member 113 by a locking member 115, and the locking member 115 is configured to move relative to the base member 113 in a first direction and to secure the movable member 114 to the base member 113 such that the movable member 114 is retained in a different position on the base member 113 in the first direction.

Fig. 3 is a top view of fig. 2, and fig. 4 is a first cross-sectional view of the testing device of fig. 1. As shown in fig. 3 and 4, one end of the movable member 114 includes a sliding slot 1141, one end of the base member 113 includes a main body portion 1131 and a sliding rail portion 1132, the main body portion 1131 is connected with the vertical beam member 111, and the sliding rail portion 1132 is disposed inside the sliding slot 1141 to realize sliding connection between the movable member 114 and the base member 113.

Here, the shape of the rail portion 1132 is not limited. For example, referring to fig. 3 and 4, the cross section of the rail portion 1132 is in the shape of an isosceles trapezoid, the small end of the isosceles trapezoid is connected to the main body portion 1131, and the cross section of the rail portion 1132 is perpendicular to the first direction.

In the disclosed embodiment, the specific structure of the locker 115 is not limited. The structure of the locking member 115 may be determined according to the structures of the movable member 114 and the base member 113. In one embodiment, the side wall of the moveable member 114 includes a locking aperture that communicates with the chute 1141 of the moveable member 114. One end of the locking member 115 is disposed in the chute 1141 through a locking hole and is used to abut against a side wall of the sliding rail portion 1132 of the base member 113, and the other end of the locking member 115 is located outside the locking hole.

Fig. 5 is a second cross-sectional view of the testing device of fig. 1. Alternatively, in one embodiment, the side wall of the moveable member 114 includes an adjustment aperture and a locking aperture that communicate with the chute 1141. Referring to fig. 5 in conjunction with fig. 2 and 4, the locker 115 includes a locking part (not shown), an adjusting lever part 1151, and a plurality of gear tooth parts 1152. One end of the locking portion is disposed in the chute 1141 through the locking hole and is used to abut against the side wall of the sliding rail portion 1132 of the base member 113, and the other end of the locking portion is located outside the locking hole, in other words, the locking portion is used to lock the movable member 114 and the base member 113. One end of the adjustment lever portion 1151 is disposed inside the slide groove 1141 through an adjustment hole. A plurality of gear teeth 1152 are disposed around the outer wall of the adjusting lever 1151 and inside the chute 1141, and the gear teeth 1152 are engaged with the rack portion 1133 of the base member 113.

When the gear tooth portion 1152 of the locking member 115 is engaged with the rack portion 1133 of the base member 113, the rotational movement of the adjustment lever portion 1151 can be converted into a linear movement, thereby smoothly moving the movable member 114 with respect to the base member 113 when the locking portion does not restrict the movable member 114 and the base member 113.

In the above, the vertical member 110 is constituted by the vertical beam member 111 and the moving member 112, however, the vertical member 110 may be of other structures. In one possible implementation, the vertical member 110 may also include a vertical beam member 111, a moving member 112, and a first driving member (not shown). The moving member 112 is movably connected with the vertical beam member 111 and is in transmission connection with the first driving member, and the moving member 112 is fixedly connected with the transverse member 120. The first driving member is connected to the vertical beam 111 and drives the moving member 112 to move along a first direction, so that the transverse member 120 drives the lens 800 to be tested to move along the first direction. The first driving member may include, but is not limited to, a linear driving device such as a cylinder, a hydraulic cylinder, or a linear motor.

In the embodiment of the present disclosure, as shown in fig. 2 and 3, the cross member 120 includes a cross member 121 and a connection seat member 122, and the rotation member 200 is disposed at the connection seat member 122. Wherein one end of the cross member 121 is connected to one end of the vertical member 110. The connection seat 122 is detachably connected to the cross member 121 and is adapted to move in the second direction to move the rotating member 200 in the second direction.

Of course, the cross member 120 may be other than the cross member 121 and the connection base member 122. Illustratively, the cross member 120 includes a cross member 121, a connection block 122, and a second driving member (not shown). The connecting base 122 is slidably connected to the beam 121 and is used for fixing the lens 800 to be tested, and the connecting base 122 can move along the second direction relative to the beam 121. The second driving member is in transmission connection with the connecting seat member 122, and the second driving member is used for driving the connecting seat member 122 to move along the second direction. The second driving member may include, but is not limited to, a linear driving device such as a cylinder, a hydraulic cylinder or a linear motor.

In the embodiment of the present disclosure, the cross member 120 is detachably connected to the connection base 122 through the cross member, so that not only the movement of the rotation member 200 in the second direction can be achieved, but also the cost of the cross member 120 can be reduced.

In the embodiment of the present disclosure, the connection manner of the cross member 121 and the connection base member 122 is not limited here. Illustratively, the beam member 121 is connected to the connection mount 122 by a threaded connection, and when the beam member 121 is connected to the connection mount 122 at a different position along the second direction, the spacing between the rotating member 200 and the vertical member 110 along the second direction is different, so as to change the position of the lens 800 to be tested relative to the calibration area in the second direction.

In one possible implementation, as shown in connection with fig. 2 above, the moving part 100 may further include a corner piece 130, a first end of the corner piece 130 being connected to one end of the vertical piece 110, a second end of the corner piece 130 being connected to one end of the lateral piece 120, and an angle between the first end and the second end of the corner piece 130 being a right angle. By connecting the uprights 110 and the cross-pieces 120 by means of corner pieces 130, it is ensured that the angle between the cross-piece 120 and the uprights 110 is at right angles.

In one possible implementation, as shown in connection with FIG. 1 above, the moving part 100 may also include a shoe 140. The shoe 140 includes a body portion 141 and a caster portion 142, and the body portion 141 is connected to the other end of the vertical member 110 and serves to fix the sign plate 700 having a marked area.

Here, the specific structure of the body portion 141 is not limited. Illustratively, the body portion 141 includes a plurality of rod-like segments connected end-to-end such that the body portion 141 is of a ring-like configuration. In one embodiment, each rod-shaped segment may be formed from a profile, thereby reducing the cost of the shoe 140.

In a possible implementation, a first end of the rotating member 200 is rotatably connected to the moving member 100, a second end of the rotating member 200 is used to fix the lens 800 to be tested, and the rotation axis of the rotating member 200 is parallel to the third direction. In testing the lens 800 to be tested, the rotating member 200 is configured to rotate around a rotation axis parallel to the third direction, so that the lens 800 to be tested rotates around the rotation axis parallel to the third direction by a preset angle.

The specific location where the moving member 100 is connected to the rotating member 200 may depend on the structure of the moving member 100. For example, referring to fig. 2, in the embodiment of the present disclosure, a rotating member 200 is rotatably coupled to a coupling seat 122 of a moving member 100.

The rotatable connection of the rotating member 200 and the moving member 100 means that the rotating member 200 is rotatably connected to the moving member 100, and the rotating member 200 has a restriction structure that restricts rotation of the rotating member 200 relative to the moving member 100.

Here, the specific structure of the rotating member 200 is not limited.

Fig. 6 is a third cross-sectional view of the testing device of fig. 1. Illustratively, referring to fig. 6, the rotating member 200 includes a carrier 210, a shaft member 220, and a limiter 230. The connecting seat 122 includes a rotation hole whose axis is parallel to the third direction. The rotating shaft member 220 is in a hollow structure and is sleeved on the rotating shaft portion 211 of the bearing member 210, and the rotating shaft portion 211 of the bearing member 210 is disposed inside the rotating hole and is used for being detachably connected with the limiting member 230. The connecting seat 122 is located between the restriction member 230 and the rotation shaft member 220 in the third direction.

Of course, the rotating member 200 may be fixedly connected to the moving member 100 and rotate the lens 800 to be tested by the rotation of the rotating member 200 itself, in addition to being rotatably connected to the moving member 100. In one embodiment, the rotating member 200 includes a rotating motor and a rotating mount (not shown), the rotating motor being fixedly connected to the rotating mount, the rotating mount being fixedly connected to a motor shaft of the rotating motor and adapted to fix the lens 800 to be tested.

In a possible implementation, as shown in fig. 1 and 2, the testing device may further include a level 300, where the level 300 is fixedly connected to the second end of the rotating member 200, and the level 300 is perpendicular to the axis of the lens 800 to be tested and perpendicular to the first direction.

As shown in fig. 2, since the level 300 and the lens 800 to be tested are connected to the same end of the rotating member 200, the level 300 and the lens 800 to be tested rotate synchronously during the rotation of the rotating member 200.

Since the level 300 is perpendicular to the axis of the lens 800 to be tested, when the level 300 is not level, then the axis of the lens 800 to be tested is not perpendicular to the calibration area. When level 300 is horizontal, then the axis of lens 800 to be tested is perpendicular to the calibration area. Therefore, by determining whether the level gauge 300 is level, it can be quickly determined whether the axis of the lens 800 to be tested is perpendicular to the calibration area.

In a possible implementation, as shown in connection with fig. 2 above, the testing device may further include a measuring member 400, where the measuring member 400 is configured to measure the distance between the lens 800 to be tested and the calibration area in the first direction.
