Ballistic calculation method based on front scope, combined sighting system and medium

A front scope configured to be mounted in front of a main scope, wherein the front scope comprises a main control module configured to implement a ballistic calculation method based on the front scope, the ballistic calculation method comprising:

• in a front mode in which the front scope is turned on, displaying an aiming reference point in a front imaging picture of a front display area;
• adjusting a movement amount of the front imaging picture in response to a movement adjustment operation for the front imaging picture to align the aiming reference point with a reticle center of the main scope, wherein an imaging light type of the front scope is different from an imaging light type of the main scope;
• acquiring a target distance value of an aiming target;
• and
• determining a current ballistic offset value for the aiming target on the basis of the target distance value and ballistic table data, and displaying a ballistic calculation reticle in the front imaging picture on the basis of the current ballistic offset value, so as to allow a sighting operation to be performed on the aiming target based on a position of the ballistic calculation reticle with respect to the reticle center.

A combined sighting system, comprising a main scope and a front scope detachably mounted in front of the main scope, wherein the front scope comprises a main control module configured to implement a ballistic calculation method based on the front scope, the ballistic calculation method comprising:

• in a front mode in which the front scope is turned on, displaying an aiming reference point in a front imaging picture of a front display area;
• adjusting a movement amount of the front imaging picture in response to a movement adjustment operation for the front imaging picture to align the aiming reference point with a reticle center of the main scope, wherein an imaging light type of the front scope is different from an imaging light type of the main scope;
• acquiring a target distance value of an aiming target;
• and
• determining a current ballistic offset value for the aiming target on the basis of the target distance value and ballistic table data, and displaying a ballistic calculation reticle in the front imaging picture on the basis of the current ballistic offset value, so as to allow a sighting operation to be performed on the aiming target based on a position of the ballistic calculation reticle with respect to the reticle center, wherein the ballistic table data comprise a correspondence between multiple sets of distance values and ballistic offset values.
