FIG. 4 is a front view of the rotation unit of FIG. 3 .

Referring to the drawings, the apparatus for testing the image quality of a camera according to the present invention includes a camera 100 and a rotation unit 200 .

Here, the camera 100 is a device for photographing the object 10, and a CCTV and a vehicle camera may be utilized.

For reference, the CCTV is mainly installed in a place such as a road or a building and is a device used for photographing an object with a fixed position, and the vehicle camera is installed in a vehicle and is in a stationary or moving state with the vehicle It is a device used for photographing objects in

In addition, the photographing object 10 may be utilized with a resolution chart (T) or a number sign (N), wherein the identification unit of the photographing object 10 is a mark for distinguishing whether to be identified when photographing with the camera 100. As a part, as an example, the resolution chart (T) is a printed part, and the number sign (N) refers to the marked number.

On the other hand, the rotation unit 200 is disposed to be spaced apart from the camera 100, the object 10 is mounted.

This rotation unit 200 serves to implement the movement of the photographing object 10 so as to test whether the camera 100 identifiably captures the identification unit of the moving photographing object 10 .

In the past, if the image quality of the camera was tested by photographing a moving car using a real site such as a road as a shooting environment, in the present invention, the object 10 is artificially moved in a separate test space for testing, not the actual site. The image quality of the camera 100 is tested by photographing the moving object 10 .

By moving the object 10 to be photographed by the rotation unit 200 in this way, the apparatus for testing the image quality of the camera according to the present invention can accurately test the image quality of the camera 100 in a quantitative way, and furthermore, it moves at various speeds. It is also possible to test the image quality of the camera 100 for the object to be photographed (10).

Specifically, the rotation unit 200 is configured to rotate the photographing object 10 rather than a linear movement in order to implement the movement of the photographing object 10 .

If the moving object is a car, and a test device is configured to photograph the left and right movement of the car, an acceleration section necessary for the car to reach the set moving speed must be provided on one side of the device installation space, and the device installation space On the other side of the interior, the deceleration and acceleration sections necessary for the vehicle to move at the set moving speed in the opposite direction after stopping should be provided.

For this reason, in order to reproduce the fast and constant speed of the vehicle, as the distance section required for the test on both sides becomes too large, there is a significant limitation in space to provide an installation space for the device.

Furthermore, in the test apparatus of this configuration, only the movement of the object moving in both directions, that is, in the left and right directions with respect to the camera 100 can be implemented, so that the object approaches or moves away, that is, in the form of moving in the forward and backward directions. There is a limitation in that the movement of

The apparatus for testing image quality of a camera according to the present invention includes a rotating unit 200 for rotating the photographing object 10 as a configuration for moving the photographing object 10 in order to overcome the above-described limitation.

Specifically, in order to test whether the camera 100 shoots the identification unit of the moving object 10 to be identifiable, the rotation unit 200 implements the left and right movement and forward and backward movement of the photographing object 10 . It takes a structure in which the object 10 is rotated and moved.

More specifically, the rotation unit 200 may include a driving member 210 and a transverse rotation bar 220 .

The driving member 210 has a longitudinal drive shaft 210a at the upper portion, in this case, the longitudinal drive shaft 210a is disposed in the longitudinal direction to rotate when the driving member 210 is operated.

As the driving member 210, an electric motor may be utilized, and if it is a driving source that provides a driving force for rotating the transverse rotation bar 220, it is not limited by the present invention and any conventional driving source may be utilized. am.

In addition, the transverse rotating bar 220 is connected to the longitudinal driving shaft 210a and has a horizontally arranged structure, and when the longitudinal driving shaft 210a is axially rotated by the operation of the driving member 210, it is rotated in conjunction with it. .

At this time, it is preferable that the middle portion of the transverse rotation bar 220 is connected to the longitudinal drive shaft 210a. Accordingly, the same photographing object 10 fixed to both ends of the transverse rotating bar 220 rotates along the same rotation route when the transverse rotating bar 220 rotates, so that a large number of times of shooting at the same location condition at a certain time This is possible, and further, the transverse rotating bar 220 uses the longitudinal drive shaft 210a as a supporting point to achieve a balance that does not incline in any direction, thereby enabling stable rotation of the transverse rotating bar 220 and preventing a safety accident in advance. can do.

Furthermore, the transverse rotation bar 220 may be configured to vary in length, and as an example, a telescopic structure may be taken to form a structure that is lengthened when the end is pulled and shortened when the end is pushed in.

Due to the variable length structure of the transverse rotating bar 220, in a long state of the transverse rotating bar 220, the effect of relatively increasing the speed of the photographing object 10 installed at the end occurs, and the length is short. In , the effect of relatively slowing the speed of the photographing object 10 installed at the end appears, and in addition, various experimental conditions related to the turning radius can be implemented.

Since the movement of the photographing object 10 is implemented as a rotational movement due to the rotation unit 200 configured as described above, the image quality test apparatus of the camera according to the present invention accelerates and decelerates according to the linear motion of the photographing object 10 . This is not necessary, so it is possible to reduce the installation space of the device, and there is no need for a stop motion for changing the direction during the linear motion of the object 10 to reduce the test time, and furthermore, the movement of the object 10 to be photographed is continuously performed at a constant speed. Accordingly, the image quality of the camera 100 can be quantitatively and accurately tested, and the image quality of the camera 100 can be tested not only in the left and right directions of the object 10 but also in the forward and backward movement.

For reference, if the photographing of the object 10 is described with reference to FIG. 2 which is a plan view, the photographing according to the left and right movement of the photographing object 10 is a rotationally moving photographing object 10 located in the 6 o'clock direction. time, and the photographing according to the forward and backward movement of the photographing object 10 may be performed in a section between approximately 10 o'clock and 8 o'clock in the photographing object 10 .

On the other hand, in the image quality test apparatus of the camera according to the present invention, the photographing object 10 is configured to be mounted on the transverse rotating bar 220, and preferably configured to be detachable. At this time, the photographing object 10 is the transverse rotating bar 220. The configuration to be installed in .

That is, the end bracket 281 has a plate shape as shown in FIGS. 3 and 4 as an example, and the fixed surface on which the photographing object 10 is fixed to the end of the transverse rotating bar 220 is a transverse rotating bar. By being vertically mounted to face the radial direction from the center of the 200, as the photographing object 10 is assembled in contact with the fixing surface with a fastening member (B) such as a bolt, the identification portion of the photographing object 10 is horizontal The rotating bar 220 may have a structure facing in the longitudinal direction.

The photographing object 10 installed in this way is used for photographing according to the left-right movement of the photographing object 10, that is, referring to FIG. 2, when the rotating photographing object 10 is positioned in the 6 o'clock direction, it is below 6 o'clock It is photographed by the camera 100 placed in the

In addition, on the side of the transverse rotation bar 220, a side bracket 282 for fixing the photographing object 10 in the longitudinal direction so that the identification portion of the photographing object 10 faces the rotation direction of the horizontal rotation bar 220 is provided. can be mounted

That is, the side bracket 282 has a plate shape as shown in FIG. 4 as an example, and is mounted so that the fixed surface on which the photographing object 10 is fixed to the side of the transverse rotation bar 220 faces the rotation direction. As a result, as the photographing object 10 is assembled in contact with the fixing surface with a fastening member B such as a bolt, the identification portion of the photographing object 10 faces the rotational direction of the transverse rotating bar 220 can be taken. .

The photographing object 10 installed in this way is used when photographing according to the forward and backward movement of the photographing object 10, that is, referring to FIG. 2, the rotationally moving photographing object 10 is approximately between 10 and 8 o'clock. When located in the section, it is photographed by the camera 100 disposed below 6 o'clock.

In addition, an upper bracket 283 for fixing the photographing object 10 in the transverse direction so that the identification portion of the photographing object 10 faces the upper side of the horizontal rotation bar 220 is mounted on the upper portion of the transverse rotating bar 220 . can

That is, the upper bracket 283 takes a plate shape as an example, and is mounted such that the fixed surface on which the photographing object 10 is fixed on the upper part of the transverse rotating bar 220 faces upward as shown in FIG. 4 , As the photographing object 10 is assembled in contact with the fixing surface with a fastening member (B) such as a bolt like the end bracket 281 of FIG. 3 , the identification part of the photographing object 10 is the upper side of the transverse rotation bar 220 . structure can be taken toward

The photographing object 10 installed in this way is used for photographing according to the above-described left-right movement of the photographing object 10 and a different type of left-right movement, that is, although not shown in the drawing, the photographing object 10 is It is photographed by a camera placed on the upper side.

In other words, the object 10 installed on the end bracket 281 moves in the left-right direction in the front-rear movement process, but the object 10 installed in the upper bracket 283 moves in the front-rear direction. By being implemented over the same distance instead of , the shooting according to the left and right movement with respect to the subject 10 has different shapes.

As an example, referring to FIG. 2 , when the photographing object 10 installed in the end bracket 281 is photographed in the 6 o'clock direction, for photographing according to the left-right movement of the photographing object 10, the photographing object ( 10) is moved from the left to the right while moving from the rear to the front (moving toward the camera 100) to reach the 6 o'clock direction.

In comparison, when the photographing object 10 installed in the upper bracket 283 is photographed in the 6 o'clock direction for photographing according to the left-right movement of the photographing object 10, the photographing object 10 is actually moved from the rear to the front. Instead of moving, it moves from left to right to reach the 6 o'clock position with almost no change in distance from the camera (not shown) disposed on the upper side.

In this way, since the photographing according to the left-right movement of the object 10 has different types, a test for the image quality of the camera can be performed under various conditions.
