  According to the present invention, the posture detection unit detects the posture of the image pickup surface of the image pickup device with respect to the image pickup element and the measurement subject, so that the correction signal output unit corrects the signal detected by the posture detection unit. By calculating a correction signal for making the positional relationship and presenting the correction signal by the display means, the operator can photograph the measurement subject with the correct positional relationship. That is, it is possible to take a picture in a state where the measurement subject and the imaging surface are parallel, the respective centers coincide, and the rotation angles around the optical axis coincide.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a functional block diagram of an image pickup auxiliary device provided in the image pickup apparatus of the present invention.
The imaging auxiliary apparatus shown in FIG. 1 includes a photographing optical system 1 that acquires optical information of a measurement subject, an imaging element 2 that forms image information from the optical system 1, and imaging information from the imaging element 2 as image data. And a posture detection unit 3 that detects the position coordinates of the vertices of a later-described rectangle (image for detecting position information) in the imaging data.

The correction signal output unit 4 has the correct positional relationship between the imaging surface of the image sensor 2 and the measurement subject based on the rectangular position information from the posture detection unit 3 (the measurement subject 10 and the imaging surface of the image sensor 2 described later are parallel). Correction information necessary to make the center of the measurement subject 10 coincide with the center of the imaging surface is generated.
The information recording unit 5 is a recording unit that records information unique to the imaging optical system.
The determination unit 6 determines the magnitude of the correction information from the correction signal output unit 4 with the value of each item set in advance, and displays the determination result on the display unit 7. That is, when the correction information is equal to or less than a preset value, a signal indicating that the image can be taken is output to the display unit 7, and when the correction information is greater than the set value, a signal prompting correction of the posture of the taken image is displayed. Output to.
The display unit 7 includes at least one of a tilt direction, a rotation angle, and a deviation amount for correcting a measurement subject 10 (to be described later) and an imaging surface of the imaging device 2 to a correct positional relationship based on a correction signal from the correction signal output unit 4. Is displayed.

2 and 3 are schematic views of the measurement subject 10 to be imaged according to the present invention.
The planar measurement object 10 shown in FIGS. 2 and 3 detects position information together with the measurement image 11 such as the resolution measurement image or the contrast measurement image shown in a simplified manner in FIG. For this purpose, a position information detection image (hereinafter referred to as a detection image) 12 is provided.

In the present embodiment, the detection image 12 is a rectangle having four arbitrary points on the measurement subject 10 as vertices. For example, as shown in FIG. 2A, arbitrary points are connected by a solid line, as shown in FIG. 2B, the intersection of cross lines is simply a rectangular vertex, and FIGS. 3D, 3E are used. Such a figure as shown in FIG. 2 (c) and FIG. 3 (f) may be used. In short, a graphic image that can easily detect the position of the vertex of the rectangle is sufficient.
Further, it is desirable that the detection icon 12 is as far as possible from the photographing center within the photographing range. In this way, the relative orientation between the imaging surface of the image sensor 2 and the measurement subject surface 10 is detected by providing the measurement object 10 with the detection image 12 that facilitates obtaining coordinate information on the imaging surface of the image sensor 2. Therefore, the correction signal output unit 4 calculates a correction signal for obtaining a correct positional relationship from the signal detected by the posture detection unit 3, and the display unit 7 presents the correction signal to the operator. As a result, the operator can photograph the measurement subject 10 with the correct positional relationship.

4 and 5, the positional relationship between the imaging surface of the imaging apparatus of the present embodiment and the measurement subject 10 is not correct, that is, the measurement subject 10 and the imaging surface of the imaging device 2 are not parallel, and the measurement subject 10 is not parallel. It is a figure which shows the case where the optical axis Z of the imaging device 13 is not orthogonally crossed.
4A and 5B, as shown in FIG. 4B, the detection image 12 formed on the measurement object 10 that is originally rectangular is not parallel to the imaging device 13 (optical axis Z). It is a figure which shows how it changes in appearance (by not orthogonally crossing).
4A and 5 are diagrams showing a method of detecting a deviation amount in the direction parallel to the plane of the image sensor between the center of the measurement subject 10 and the center of the image sensor 2. First, FIG. A case where only the rotation around the vertical axis of the imaging surface is given to the measurement subject 10 will be described using FIG.
In this case, the inclination of the optical axis Z of the imaging optical system with respect to the measurement subject can be detected from the coordinates of two types of intersections in the rectangle. Each value can be calculated from the equation in Table 1.

4A, when the correct positional relationship between the measurement subject 10 and the image pickup optical system (the optical system 1 and the image pickup device 2) is lost, the change in the detection image 12 on the image pickup surface is It is possible to detect the direction and quantity.
More specifically, a line segment connecting the midpoints (A (Xa, Ya), B (Xb, Yb), D (Xd, Yd), E (Xe, Ye)) of the opposing sides of the detection image 12. When AB and line segment DE are the X-axis and Y-axis, respectively, each side is projected on the X-axis or Y-axis, the difference between the lengths h and i, and the rotation about the X-axis or Y-axis from the difference between j and k The direction can be detected.

Alternatively, the detection image 12 also depends on the distance between the origin C ′ (XC ′, YC ′), which is the intersection of the X axis and the Y axis, and the intersection C (XC, YC) of the diagonal line of the detection image 12 and the direction thereof. As a result, the direction and amount of rotation of the measurement subject 10 around the X axis or Y axis can be detected. That is, it is possible to detect the inclination direction of the optical axis Z of the imaging optical system with respect to the measurement subject 10 and the amount of deviation thereof.
This is because the intersection of the lines connecting the midpoints of the opposite sides of the rectangle viewed from the vertical direction and the intersection of the diagonal lines are inherently coincident with each other, and these deviations indicate that the rectangle is not perpendicular to the optical axis. Because it means.

Here, when the distance in the X-axis direction between the origin C ′ and the intersection C is g and the distance in the Y-axis direction is f, as shown in Table 1, the distance g is represented by XC′−XC, and the Y-axis Although the direction distance f is represented by YC′−YC, in this embodiment, since only rotation about the vertical axis of the imaging surface is given, YC ′ = YC, and the deviation amount in the Y-axis direction is Absent. That is, it can be seen that the inclination of the optical axis Z is the inclination of the measurement subject in the X-axis direction.

Next, FIG. 5A is a diagram illustrating a case where the measurement subject 10 is rotated around both the X axis and the Y axis. In this case, the rotation angle around the optical axis of the imaging optical system of the imaging apparatus is detected.
As in FIG. 4 (a), in this case as well, the rotation direction of the measurement subject 10 is determined by the difference between h and i, the difference between j and k, or the distance and direction between the intersection C of the diagonal and the origin C ′ of the XY axis. And the amount is known. The direction of rotation of the detection image 12 and the measurement subject 10 around the X or Y axis also depends on the distance and direction between the origin C ′, which is the intersection of the X axis and the Y axis, and the intersection C of the rectangular diagonal line. And can detect the amount. That is, it is possible to detect the tilt direction of the optical axis Z of the imaging optical system with respect to the measurement subject and the amount of deviation thereof.
The distance in the X-axis direction between the origin C ′ and the intersection C is g, and the distance in the Y-axis direction is f. As shown in Table 1, the distance g is represented by XC′-XC, and the distance f in the Y-axis direction is represented by YC′-YC.

FIG. 5B shows a case where rotation around the Z axis, which is the optical axis of the imaging optical system 1 of the imaging apparatus 13, is added to the state of FIG. In this case, the posture of the measurement subject plane cannot be defined only by the difference between h and i and the difference between j and k, but Y = lX + m, (X2) connecting diagonal lines ((X1, Y1) and (X3, Y3)) , Y2) and (X4, Y4) is represented by Y = 1'X + m '), and the distance and direction between the origin C' of the XY axes and the measurement object 10 in the same manner as in FIG. The direction and amount of rotation can be detected.
Further, from the distance between the center of the imaging surface (not shown) and the intersection C of the diagonal line, the amount of movement in the direction parallel to the object plane between the center of the measurement subject 10 and the center of the imaging device can also be detected. As described above, it is possible to specifically detect the posture of the measurement subject 10 with respect to the imaging surface.

Next, a procedure in which the correction signal output unit 4 of the photographing assisting apparatus according to the present embodiment obtains the posture correction direction and amount using the signals detected by the posture detection unit 3 from the relationship shown in FIG. Will be described with reference to FIG.
As shown in FIG. 6, the output signal of the measurement subject 10 imaged on the image sensor 2 by the imaging optical system 1 is first taken into the posture detection unit 3 (S1), and then the rectangular shape on the measurement subject 10 is taken. The position coordinates of the four corners are detected (S2). Upon receiving the information, the correction signal output unit 4 calculates each value shown in Table 1 from the four detected position coordinates (position table of the four corners of the rectangle), and images the measurement subject 10 and the image sensor 2. A correction signal necessary for making the surfaces parallel and aligning the respective centers is output.
That is, the origins C ′ (XC ′, YC ′) connecting the centers A (Xa, Ya), B (Xb, Yb), D (Xd, Yd), E (Xe, Ye), and ABDE of the four sides of the rectangle. Then, a diagonal intersection C (XC, YC) is calculated (S3).

Next, the X axis (represented by Y = n′X + o ′) connecting A and B and the horizontal axis angle θx of the imaging surface, and the Y axis (representing Y = nX + o) connecting D and E, and the vertical of the imaging surface An angle θy with respect to the axis is calculated (S4).
If θx = θy (YES in S5), in step S7, the diagonal line C between the diagonal line C and the horizontal axis distance between the vertical axis of the imaging surface and the horizontal axis, and the diagonal line C And f, which is the distance in the vertical axis direction between the intersection of the vertical axis and the horizontal axis of the imaging surface, to generate a direction / unit conversion and correction signal (S8).
If θx ≠ θy (NO in S5), θX and θY are calculated in step S6, and a direction / unit conversion correction signal is generated (S8). The generated direction / unit conversion correction signal is sent to the determination unit 6 to perform determination processing (S9), and thereafter, display processing is performed in the display unit 7 (S10).

The determination unit 6 outputs a signal indicating that photographing is possible to the display unit 7 when the correction amount is equal to or less than a preset value, and displays a signal prompting the correction of the posture of the imaging device when the correction amount is equal to or greater than the set value. Output to. In this way, when the amount of correction is less than or equal to a preset value, a signal indicating that photography is possible is displayed, and when it is greater than or equal to the set value, an operation for prompting correction of the attitude of the imaging apparatus can be performed. Therefore, the work can be simplified. Further, if the measurement accuracy is to be relaxed or increased, the setting value of the determination unit 6 can be changed to change the value from a value preset by the measurement operator.
The display unit 7 receives the correction signal from the correction signal output unit 4 and displays at least one of the tilt direction, the rotation angle, and the deviation amount for correcting the measurement subject 10 and the imaging surface to the correct positional relationship. Thus, the operator can easily confirm.

  In addition, in the imaging auxiliary device of the present embodiment, information unique to the imaging optical system can be recorded. Can be recorded. Therefore, the accuracy of the correction signal calculated by using this unique information in the correction signal output means can be increased. Specifically, it is conceivable to use the amount of distortion that varies depending on the image height, focal length, and object distance.

Hereinafter, an imaging apparatus will be described as an optical apparatus including the imaging auxiliary apparatus according to the present invention.
When using the imaging assistance device of the present embodiment, it is necessary to input special operations that are not performed when optical devices are generally used. As a result, it is possible to incorporate the imaging assisting device of the present embodiment in a so-called service mode in the imaging device for the user.
In addition, since it is possible to use a liquid crystal display monitor for confirming a photographed image or a liquid crystal monitor for photographing information display of the imaging device as the display unit 7 of the imaging auxiliary device of the present embodiment, the display unit 7 is added separately. Cost can be suppressed without any problems. Further, since a large and high-definition color display can be achieved, it is possible to display a detailed correction signal.
It is possible to record the signal of the correction signal output unit 4 in the data area of the picked-up image. This makes it possible to verify the posture when the picked-up image data is picked up after moving from the image pickup apparatus.
