Abstract

PROBLEM TO BE SOLVED: To solve the problem of causing the error of a hit deviation computed value by the impact of a shot in a shot control device mounted on a vehicle body because of a requirement of fixing a visible image pickup part and an ultraviolet image pickup part in an inertial space in order to accurately compute hit deviation, in the case of acquiring an image in the collimated state by the visible image pickup part and an image in the hit state by the ultraviolet image pickup part and composing these images to compute the hit deviation. SOLUTION: The jolting amount of a vehicle body when hit, caused by the impact of the shot is detected, and the fluctuation amount is corrected to the hit image of the ultraviolet image pickup part by an image composition processing part. Matching processing is further performed between the collimated image of the visible image pickup part and the image of the visible image pickup part in the stationary state of the vehicle body after shot, and an azimuth fluctuation portion in the inertial space of the vehicle body is also corrected to reduce the error of the hit deviation computed value.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a vehicle-mounted shooting control device for calculating a landing deviation,
Furthermore, the present invention relates to a shooting control device that reduces an error in a landing deviation detection value due to a change in a vehicle body caused by a shock at the time of shooting.

2. Description of the Related Art FIG. 4 is a diagram for explaining an application example of a conventional shooting control device. In the figure, 1 is a visible image pickup unit,
2 is an ultraviolet imaging unit, 3a is a visible imaging processing unit, 4 is an ultraviolet image processing unit, 5 is a percussion trigger signal line input from the outside, 6 is an aiming image, 7 is an impacting image, and 8a is an image combining process. Reference numeral 9a denotes a landing deviation output signal line.

Here, a conventional technique will be described. When firing a gun or gun, aim and fire the target. However, depending on the characteristics of the gun or gun and the environmental conditions such as temperature, it is not always possible to hit with one shot. When shooting again without hitting, if the difference between the place where the first shot is made and the place where the bullet has arrived, that is, the deviation in impact is known, the deviation is corrected to the aiming point, and the next hit is made. The likelihood of doing so increases. However, it is difficult to confirm the landing deviation with human eyes, and even if it is possible, it will take time,
It will take a long time to shoot again. Therefore, the visible image pickup unit 1
And the ultraviolet ray imaging unit 2 are combined, and these images are combined to automatically calculate the landing deviation and reduce the time required for another shot. Here, the reason why both visible light and ultraviolet light are necessary is as follows.

Although the aiming point can be seen in the visible image, it is difficult to see the impact point due to the influence of the flame generated by the gun or gun during shooting. On the other hand, in an ultraviolet image, since the bullet emits light in the ultraviolet range when it is hit, the hit point is visible, but the aim point is difficult to see.

In the prior art, the visible image processing section 3
The aiming image 6 output by a and the hitting image 7 output by the ultraviolet ray image processing unit 4 are combined by the image combining processing unit 8a, and the hitting deviation 9a is output. FIG. 5 is an image diagram for explaining the processing contents of the video composition processing unit 8a. The aiming image 10 and the landing image 11 are overlapped to create a composite image 12,
By calculating the difference between the aiming point and the landing point, the landing deviation 9a
Is output.

[0006]

In the shooting control device as described above, the visible image pickup portion 1 and the ultraviolet ray image pickup portion 2 are fixed, and the aiming image 6 and the hitting image 7 are relatively matched. Is a necessary condition. That is, in the shooting control device mounted on the vehicle, an error occurs in the landing deviation 9a due to the impact of the shooting of the gun or the gun. FIG. 6 is an image diagram for explaining this error. Since the aiming image 6 and the landing image 7 are relatively displaced, the composite image does not look like the composite image 12 in FIG. Image showing error As shown in FIG. 13, an error occurs in the landing deviation 9a.

The causes of this error are the following two. One is that the direction of the ultraviolet imaging unit 2 at the time of landing moves due to the impact, and the aiming image 6 and the landing image 7 do not relatively match. Another factor is that the azimuth of the vehicle body before and after shooting moves due to the impact, and the aiming image 6 and the landing image 7 do not relatively match.

The present invention has been made in order to solve such a problem, and proposes a shooting control device which corrects a variation in the orientation of a vehicle body or the like due to a shock of shooting to reduce a calculation error of a landing deviation. It is a thing.
