Abstract

The present invention relates to a method for embedded combat vehicle gun target tracking training performed at an electronic device, an electronic device for performing the method and a computer readable storage medium storing one or more programs for performing the method. The method comprises determining a trajectory of a virtual target for a period of time; determining an aim point location of the weapon system; displaying, on a display device, a first and second graphical object overlaid onto an image sequence, wherein the first graphical object represents an aim point location of the weapon system and wherein the second graphical object represents a virtual target which moves along the determined trajectory. User inputs are received representative of control signals for causing weapon system movements and the second graphical object is updated based on the weapon system movements.

Description

1 EMBEDDED TARGET TRACKING TRAINING TECHNICAL FIELD The present invention relates to a method for embedded combat vehicle weapon system 5 target tracking training as described herein. The present invention also relates to an electronic device and a computer readable storage medium for performing the method. BACKGROUND ART Today there exist numerous examples of training systems for training of operators of various weapon system of combat vehicles such as armoured vehicles, tanks and infantry 1 O fighting vehicles. One type of training system for training target tracking of a combat vehicle is based on using one or more physical target such as target cards or resettable target spots. However, such training systems requires space consuming external installations in a controlled training environment. 15 Another form of training systems are live training systems such as laser based training systems wherein vehicles are equipped with laser transmitters and receivers for enabling simulating firing events by means of the transmitters and detecting hit events by means of the receivers. While these type of training systems provide efficient means for training of crew members of a combat vehicle it is also costly since relatively complex equipment 20 needs to be fitted onto multiple objects such as vehicles. Furthermore, in order to practise target tracking for moving target more than one vehicle needs to be included in the training whereby the training cost is relatively high due to fuel consumption and increased number of crew members. Yet another form of training system are combat vehicle simulators wherein for example a 25 desktop computer is used to simulate a vehicle, its weapon systems and targets in an Date Re9ue/Date Received 2024-02-22 89893446 2 environment around the vehicle. Such type of training systems can also be provided within a mock-up vehicle. However, while using a desktop computer can provide cost efficient training the degree of realism will be limited. Also, using a mock-up vehicle for training requires a complex and costly installation. 5 Thus, there exists a need to present improvement within training systems training target tracking for example to improve training of combat vehicle gunners. OBJECTS OF THE INVENTION An object of the present invention is to provide a more efficient method for combat vehicle gun target tracking training. 10 An additional object of the present invention is to provide method for combat vehicle gun target tracking training which is simple and cost effective. An additional object of the present invention is to provide method for combat vehicle gun target tracking training with improved availability by avoiding requiring complex and costly training facilities. 15 SUMMARY OF THE INVENTION These and other objects, apparent from the following description, are achieved by a method for embedded combat vehicle gun target tracking training, a computer readable storage medium and an electronic device, and an electronic device According to the invention, the objects are achieved by a method at a combat vehicle for 20 embedded combat vehicle weapon system target tracking performed at the combat vehicle. The combat vehicle comprises an electronic device with a display device and input means. The method is performed at said electronic device with a display device and input means. The method Date Re9ue/Date Received 2024-02-22 3 comprises: determining a trajectory of a virtual target for a period of time; determining an aim point location of the weapon system of the combat vehicle based on a current pointing direction of the gun along an azimuth and an elevation direction. The method further comprises obtaining an image 5 sequence of a sight camera associated with the weapon system of the combat vehicle; displaying, on the display device: said image sequence; a first graphical object, overlaid on the image sequence, wherein the first graphical object is representative of the aim point location and displayed on a first position on the display device to indicate the determined aim point location of 10 the weapon system; and a second graphical object, overlaid on the image sequence, wherein the second graphical object is representative of the virtual target and displayed on a second position on the display device to indicate a starting position of the virtual target based on the determined trajectory over the period of time; while displaying the graphical objects on the display device: 15 updating display of the second graphical objects by moving the second graphical object from the second position along the determined trajectory over the period of time; and receiving, via the input means, one or more user inputs representative of one or more control signals causing movement of the pointing direction of the weapon system along the azimuth and/or the elevation 20 direction; in response to receiving the one or more user inputs updating display of the first graphical object by moving
