Abstract

PURPOSE:To direct a sighing shaft toward a target at the time of representing even if the target is concealed by an obstacle for a long period of time while a own vehicle is traveling by providing a speed detector, a self-position calculator, a target position calculator, a data holder, a target angle presuming calculator and a switching unit in a conventional sighting instrument. CONSTITUTION:A self-position calculator 14 calculates the position of a vehicle on a plane from the direction and the speed of the vehicle to obtain positions A0 A1 A2. A target position calculator 15 calculates a target position from a target angle (d) and the output of a range finder 8 with the present position of the vehicle as a reference to obtain a position B0. If the target is concealed, data of the target position B0 immediately before is held by a data holder 16, and a target angle presuming calculator 17 calculates and outputs the angle of the 80 as seen from the A at the time from the difference between the data B0 of the holder 16 and the present position data A of the vehicle. A switching unit 18 inputs the output of the calculator 17 to a servo circuit 6 while the target is concealed. Thus, when the vehicle arrives at the A2, a sighting line is directed the direction l2 of the target.

When the target (12) comes within the field of view of the visible TV camera (7), its image will be as shown in FIG. The image processor (9) processes both images and calculates the amount of deviation between the aiming axis (13), which is the center of the screen, and the target image center axis (14), and outputs this as a tracking deviation signal. do. The tracking deviation signal consists of components in two axis directions, the X-axis and the X-axis shown in FIG. 2, and is sent to the target angle calculator. Target angle calculator (
In 2), the angle of the target (12) with respect to the north reference horizontal coordinate is calculated. FIG. 7 is an explanatory diagram of this calculation,
In order to make the explanation easier to understand, this figure shows only the angular relationships on the horizontal plane, and the explanation will be made accordingly. Attitude angle signal a
The tracking deviation signal C and the servo angle signal C correspond to angles as shown in FIG. Therefore, the target for the north (1

The V camera (7) will be driven. When the visible TV camera (7) faces the target (I2), the coaxial laser range finder (
8) irradiates the target (12) with a laser and calculates the target distance based on the reflected light. The target position is determined by obtaining this target distance signal and the target angle signal d. These are the target specifications for gun control, that is, the control of the turret (9) and gun (10), and are the output of the aiming device.

With the conventional aiming device as described above, when aiming at the target (12) while the vehicle (11) is moving, it is fine when the target (12) is being tracked with the visible TV left camera 7), but when the vehicle (11) is tracking the target (12) with the visible TV left camera 7), it is fine. Naturally, if the target (12) is hidden behind an obstacle, it becomes impossible to obtain a tracking deviation signal. Therefore, the target angle signal just before it is hidden by the conventional aiming device is stored in the target angle calculator (12), and this is input to the servo circuit (5) until the target appears again. )
I try to keep the direction of the target, that is, the aiming axis, in a fixed direction. However, this method is good if the target (12) is hidden for a short time and the speed of your vehicle (11) is slow, but if the target (12) is hidden for a long time or the vehicle (
If the speed of 11) is high, the direction of the aiming axis when the target (12) reappears and the direction of the target (12) will deviate greatly, and the target (12) will not be captured within two screens, resulting in the task of searching for the target again. There was a problem that it had to be done.
