DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described with reference to the drawings for explaining a peripheral monitoring apparatus of a vehicle according to embodiments of the present invention.

FIG. 1 is a block diagram showing a vehicle surroundings monitoring apparatus according to an embodiment of the present invention.

The peripheral monitoring apparatus 1 of the vehicle according to the embodiment of the present invention includes an image obtaining unit 100, a distortion correcting unit 200, a peripheral image generating unit 300, and a control unit 400 .

The image acquisition unit 100 may include a plurality of cameras 111 to 114 and an image processing unit 120.

The plurality of cameras 111 to 114 may serve to acquire images of different directions around the vehicle.

As shown in FIG. 2, the plurality of cameras 111 to 114 are respectively installed in front, back, left and right directions of the vehicle to acquire images of the vehicle in all directions. For example, It can be installed near the bumper or near the left and right outside mirrors.

In the embodiment of the present invention, a plurality of cameras 111 to 114 are referred to as a first camera 111, a second camera 112, a third camera 113, and a fourth camera 114, The images obtained by the first to fourth images 111 to 114 will be referred to as a first image 111a, a second image 112a, a third image 113a and a fourth image 114a.

In this case, in the embodiment of the present invention, a case where a plurality of cameras 111 to 114 are installed in front, rear, left, and right directions of the vehicle will be described as an example. However, The number of installations may vary.

For example, in a case where a wide angle lens having a relatively large angle of view is used for a plurality of cameras 111 to 114, the number of installations can be reduced, and when a narrow angle lens is used, the number of installations can be increased.

The image obtained by the plurality of cameras 111 to 114 may be an image in the forward direction of the vehicle, that is, in a direction of 360 degrees. As described above, the plurality of cameras 111 to 114 may be arranged in front, When installed, each camera may be a camera using a wide-angle lens having an angle of view of approximately 180 degrees.

Further, in order to acquire an image of the vehicle in all directions, the plurality of cameras 111 to 114 do not necessarily have to be installed in the front, rear, left, and right directions of the vehicle, The installation position can be changed variously.

As described above, when a wide angle lens is used for the plurality of cameras 111 to 114, a wide angle of view can be realized. On the other hand, since the distortion of the image, that is, radial distortion, The image obtained by the distortion correction algorithms 111 to 141 may be subjected to distortion correction processing by the distortion correction algorithm.

The image processing unit 120 may convert the image obtained by the plurality of cameras 111 to 114 into a compression format so as to facilitate data transmission before transmitting the image to the distortion correction unit 200, -1 or MPEG-4 may be used.

In addition, the image processing unit 120 may correct a tolerance that occurs when a plurality of cameras 111 to 114 deviate from a preset installation position or installation angle, and a detailed description thereof will be described later.

As described above, the distortion correction unit 200 may correct the radial distortion caused when the wide-angle lens is used in the plurality of cameras 111 to 114. The distortion correction unit 200 may perform a predetermined distortion algorithm And corrects the acquired image according to the correction rate.

Here, in the embodiment of the present invention, a case where a wide angle lens is used for a plurality of cameras 111 to 114 to correct radial distortion through the distortion correction unit 200 is described as an example. However, In this case, the image obtained by the image obtaining unit 100 may be subjected to a radial distortion correction process without being subjected to a radial distortion correction process, And may be transmitted to the image generating unit 300.

The peripheral image generating unit 300 synthesizes the images 111a to 114a acquired by the plurality of cameras 111 to 114 to generate a peripheral image of a top view type as viewed from above the vehicle, An icon or an image representing a vehicle may be inserted into the empty space in the center portion.

At this time, the peripheral image generating unit 300 may synthesize the image before the radial distortion correction according to the presence or absence of the distortion correction unit 200, and may synthesize the image after radial distortion correction. In the embodiment of the present invention, A case where the generating unit 300 generates a peripheral image 310 by synthesizing an image obtained by correcting the radial distortion by the distortion correction unit 200 will be described.

The peripheral image 310 generated by the peripheral image generating unit 300 is displayed through various display devices such as a navigation system, an AV system, and a HUD (Head Up Display) provided in the vehicle, so that the driver can see the pedestrian 311 And the surrounding vehicles 312 and the like in advance.

At this time, when the plurality of cameras 111 to 114 have predetermined installation heights or installation angles, the peripheral image generation unit 300 normally generates the peripheral images 310 so that the driver recognizes the obstacles 311 and 312 However, when a physical error, that is, a mechanical error, occurs, and a plurality of cameras 111 to 114 deviate from a predetermined installation height or installation angle, a tolerance is generated. In this case, At least one 312 of the obstacles 311 and 312 is not normally displayed and it is difficult for the driver to recognize the obstacles 311 and 312 correctly.

Therefore, in the embodiment of the present invention, the control unit 400 performs a process of correcting the tolerances generated in the plurality of cameras 111 to 114, and in the process of correcting the tolerances of the plurality of cameras 111 to 114 Will be described in detail.

In the embodiment of the present invention, in order to correct the tolerances generated in the plurality of cameras 111 to 114, a plurality of correction patterns P are positioned around the vehicle as shown in FIG. 5, and then a plurality of cameras 111 to 141 The control unit 400 obtains a plurality of images 111a to 114a including the plurality of correction patterns P and the plurality of correction patterns P3 included in the peripheral image 310 generated by the peripheral image generation unit 300 P to detect the correction points necessary for calculating the correction values for correcting the tolerances of the plurality of cameras 111 to 114. [

The position and the number of the correction pattern P used when correcting the tolerances generated in the plurality of cameras 111 to 114 can be variously changed.

The correction pattern P may include a plurality of pattern areas P11, P12, P21, and P22 having different brightness levels as shown in FIG. 6. In the exemplary embodiment of the present invention, The regions P11 and P12 are referred to as high luminance regions and the pattern regions P21 and P22 having luminance lower than the reference luminance are referred to as low luminance regions.

The reason why the correction pattern P is composed of the high luminance areas P11 and P12 and the low luminance areas P21 and P22 is that edge detection is easy due to the luminance difference between the two areas, CP) may be determined at a predetermined point of the detected edge.

For example, when the correction pattern P is alternately arranged in a plurality of directions in the high luminance areas P11 and P12 and the low luminance areas P21 and P22 as shown in FIG. 6, The edge E1 and the longitudinal edge E2 of the transverse edge E1 and the longitudinal edge E2 of the transverse edge E1 can be respectively detected and the point at which the transverse edge E1 and the longitudinal edge E2 intersect can be detected by the correction point CP .

In the embodiment of the present invention, the high brightness areas P11 and P12 and the low brightness areas P21 and P22 are each composed of two areas. However, the present invention is not limited to this, The number and arrangement direction of the high luminance areas P11 and P12 and the low luminance areas P21 and P22 can be variously changed according to the detection standard.

In the embodiment of the present invention, detecting a point at which a transverse edge E1 intersects a transverse edge E2 with a correction point CP is merely an example for facilitating understanding of the present invention, The present invention is not limited to this, and the correction point CP may be determined as a predetermined point.

The shape of the correction pattern P is not limited to the above-described embodiment, and may have various shapes according to the criteria for detecting the correction point CP.

In the embodiment of the present invention, a white pattern is used for the high luminance areas P11 and P12, and a black pattern is used for the low luminance areas P21 and P22. However, But the present invention is not limited to this, and colors other than the white color and the black color having a large luminance difference may be used to facilitate edge detection.

5, since the control unit 400 includes a plurality of correction patterns P around the vehicle, the control unit 400 can detect the correction points CP for the respective correction patterns P, The control unit 400 will describe a case where the positional relationship between each correction pattern P (for example, coordinates, etc.) is stored in advance in the embodiment of the present invention.

In other words, since the control unit 400 knows the positional relationship between the respective correction patterns P, when the correction point CP of each correction pattern P is detected, the positional relationship between two or more correction points P Can be compared with the previously stored positional relationship to determine whether a tolerance has occurred and the tolerance can be corrected by correcting the positional relationship between the detected correction points CP to be equal to the previously stored positional relationship.

At this time, when the ambient light such as natural light or artificial light is incident on the correction pattern P, when the image is acquired by the camera due to the reflected light reflected by the correction pattern P, A phenomenon in which the luminance of the liquid crystal panel is varied may occur.

That is, when the ambient light L1 is acquired by the camera due to the reflected light L2 incident on at least one of the low-luminance areas P21 and P22 of the correction pattern P and reflected thereon as shown in FIG. 8, When at least one of the low luminance areas P21 and P22 of the correction pattern P included in the image is recognized as a high luminance area as shown in Fig. 9, it is difficult to detect the edge and it is difficult to detect the correction point CP .

For this, in the embodiment of the present invention, in the embodiment of the present invention, the reflected light L2 reflected by the correction pattern P is scattered, that is, the reflected light L2 incident on the camera is reduced At least a part of the correction pattern P is formed as a diffuse reflection region so that the luminance increase phenomenon due to the ambient light L1 is prevented.

For example, as shown in FIG. 11, the surface of the correction pattern P may be roughened through sandpaper or the like, or may be formed of a material having a surface of the correction pattern P itself, It is possible to reduce the reflected light L2 incident on the camera and make it possible to accurately detect the correction point CP.

12, a diffusive layer M may be disposed on at least a part of the correction pattern P so that the reflected light L2 is irregularly reflected. The diffusive layer M may be made of a diffusive coating or a film, Or a cover for diffuse reflection (for example, diffused reflection glass) or the like.

When at least one of the pattern areas P11, P12, P21 and P22 of the correction pattern P is formed, it is also possible to reduce the reflected light L2 by using irregularly reflecting ink, paint or the like.

The method of forming the diffusive region in at least a partial region of the correction pattern P is not limited to the above-described examples, and various methods capable of causing the incident ambient light L1 to be scattered can be used.

As described above, in the embodiment of the present invention, at least a partial region of the correction pattern P is formed as a diffusely reflecting region in which the reflected light L2 is diffusely diffused. However, in the present invention, It can be understood that the reflected light is diffusely reflected by using the various methods described above in the low luminance region.

As described above, in the embodiment of the present invention, reflected light is scattered by the correction pattern P to prevent the brightness from increasing, so that the correction pattern can be correctly recognized by the camera.

The control unit 400 synthesizes the images including the plurality of correction patterns P acquired by the plurality of cameras 111 to 114 by the peripheral image generation unit 300 to generate the peripheral image 310 The correction point CP is detected from the plurality of correction patterns P and a correction value for correcting the tolerance for the plurality of cameras 111 to 114 is calculated from the detected positional relationship of the correction points CP do.

For example, when the correction point CP detected from the peripheral image 310 generated by the peripheral image generation unit 300 is the same as that shown in FIG. 13, the control unit 400 determines the positional relationship between the correction points CP It can be judged.

That is, as described above, since the control unit 400 stores the positional relationship among the plurality of correction patterns P located in the vicinity of the vehicle in advance, the positional relationship between the correction points CP corresponds to the pre-stored positional relationship It is possible to calculate a correction value for correcting the image obtained from the plurality of cameras 111 to 114.

For example, the control unit 400 detects that the positional relationship of any two correction points CP included in the first image 111a acquired by the first camera 111 is inclined at a predetermined angle from the predetermined position It is possible to calculate a correction value for compensating for the tolerance caused thereby.

The correction value calculated by the control unit 400 is transmitted to the image processing unit 120 of the image obtaining unit 100 and the image processing unit 120 obtains the correction values obtained by the cameras 111 to 114 At least one of the images may be corrected in accordance with the transmitted correction value, for example, the image may be rotated in a predetermined direction so that each of the correction points CP has a predetermined positional relationship.

In the embodiment of the present invention, the image processing unit 120 corrects the tolerance of the image according to the correction value transmitted from the control unit 400. However, May be performed at any stage before being displayed through the display device.

In the embodiment of the present invention, the image processing unit 120 is included in the image obtaining unit 100. However, the present invention is not limited thereto, and the image processing unit 120 may be separately configured to perform tolerance correction It is possible.

As described above, in the embodiment of the present invention, a process for correcting the tolerance separately by previously correcting the case where the image is not normally acquired due to the tolerance generated in the plurality of cameras 111 to 114 through the correction pattern P It is possible to easily correct the image without going through.

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. The scope of the present invention is defined by the appended claims rather than the foregoing detailed description, and all changes or modifications derived from the meaning and range of the claims and the equivalents thereof are included in the scope of the present invention Should be interpreted.
