【Example】

 Example 1. FIG. 1 is an overall configuration diagram of an embodiment of an automatic aiming device according to the present invention. In FIG. 1, reference numeral 1 is a target information acquisition unit composed of an imager for capturing an image of the target and an image around the target and a rangefinder for obtaining the distance to the target, and 2 is the acquired target information and information necessary for aiming. Aiming display means for providing information to an occupant, 3 is target extraction means for separating and extracting a selected shooting target from the background, 4 is shot distribution acquisition means for grasping distribution status of shots, 5 Is a weapon information acquisition means for obtaining the type of bullet and the initial velocity of the shot, 6 is a target selection means for the occupant to select a shooting target, and 7 is an aiming point from the extracted target and the obtained distribution of the shots. An aiming point determining means for deciding the gun, and 8 is a firearm control means for pointing and controlling the gun to the decided aiming point.

Next, the automatic aiming device will be described. The target peripheral image including the shooting target obtained by the target information acquisition unit 1 is presented to the tank occupant on the aiming display unit 2, and at the same time, the occupant selects and designates the shooting target and prompts aiming. Target selection means by operating a steering wheel or the like may be adopted for the instruction to select the shooting target as in the conventional case. The selected target is subjected to image processing by the target extracting means 3 to be separated from the background, and the silhouette of the target is output. The distance to the target obtained by the target information acquisition means 1 is given to the shot distribution acquisition means 4, and the shot distribution acquisition means 4 outputs a shot distribution according to the shot distance. The target silhouette and the shot distribution are input to the aiming point determining means 7, and the aiming point is determined so that the overlapping area of the target silhouette and the shot distribution is maximized, that is, the hit probability is maximized, and the aiming point coordinates are determined. Is output to the target selecting means 6. The target selecting means 6 prompts the aiming display means 2 to generate an aiming reticle at the aiming point coordinates output by the aiming point determining means 7, and superimposes it on the target peripheral image including the shooting target obtained by the target information acquiring means 1. To display. The firearm control means 8 controls the direction of the gun so that the bullet hits the aiming point coordinates determined by the aiming point determining means 7.

Next, the operation of acquiring the shot distribution will be described with reference to FIG. FIG. 2 shows the structure of the shot distribution acquisition means 4 in FIG. After the aiming point is determined as described above, when the shooting is performed and the bullet is fired, the firearm information acquisition means 5 obtains the firing signal, the information such as the initial velocity of the shot, and the type of the bullet, and the shot distribution acquisition means 4 Give to. In the shot distribution acquisition means 4 shown in FIG. 2, the timer 10 is started by the firing signal. The arithmetic processor 11 calculates the time immediately before the bullet reaches the target by firing the bullet from the bullet type, the initial velocity of the bullet, and the distance to the target, and reaches the time while referring to the output time of the timer 10. Then, the timing signal is output to the target extracting means 3. Upon receiving the timing signal, the target extraction means 3 fetches the target peripheral image immediately before the shot from the target information acquisition means 1 reaches the target into the image processing memory and performs the shot extraction processing. The image information after the extraction processing and the aiming point coordinates determined by the aiming point determining means 6 are given to the image memory 12 of the shot distribution acquiring means 4. Since the image information in the image memory 12 varies depending on the type of bullet and the distance of the target, that is, the shooting distance, normalization processing is performed. The arithmetic processing unit 11 of the shot distribution acquisition means 4 normalizes the image information in the image memory 12 into information for each bullet type at a certain distance and stores it in the shot distribution memory 13 for each bullet type. On the contrary, in the aiming point determination operation, the arithmetic processor 11 enlarges / reduces the shot distribution information of each shot type in the shot distribution memory 13 to a size corresponding to the distance to the target and the shot distance. Output to 12. The shot distribution information output to the image memory 12 is input to the aiming point determining means 7.
