A portable system for facilitating inclined shooting of projectile weapons comprises a ranging system, an inclinometer and a processor. The ranging system measures a line-of sight range distance from a vantage point to a target that is elevated or depressed relative to the vantage point, and the inclinometer measures an inclination angle of a line of sight between the vantage point and the target. Based on information from the rangefinder and inclinometer, the processor determines a predicted altitude-compensated inclined shooting (ACIS) trajectory at the line-of sight range distance for a preselected projectile. The ACIS trajectory is based on a bullet path height correction between a bullet path height at a first altitude and a bullet path height at a second altitude, a range distance of the target from the vantage point, and selected meteorological atmospheric information.

A rangefinder having improved display capabilities. The rangefinder has a ranging system., a processor, and a display. The rangefinder may have a multi-position button for inputting data, and may also have an inertial navigation unit. The rangefinder has improved input and tracking of wind direction and speed, allowing for improved ballistic compensation for wind.

An optical device with at least one measurement scale for the determination of the distance to an object with an at least approximately known size observed by the measurement scale. In order to make possible a quick, object size-independent readability of measurement values and a simpler calculation of the distance to an object from the read-off measurement values, the measurement scale includes a reference marking and at least one additional measurement marking with a numerical value that is correlated with it and that is inversely proportional to the distance of the reference marking from the pertinent measurement marking. The distance to the object observed by the measurement scale is produced by a multiplication of the size of the object with a measurement value read off from the measurement scale.

The present invention relates to an electronic range estimator for accurately measuring the distance/range of the remote object that is seen through the smart weapon scope device. The distance/range of the remote object is measured based on the vertical height of the remote object and the orientation angles measured for the remote object. Further, the electronic range estimator computes the distance/range of the remote object based on the vertical height of the remote object and the orientation angles measured for the remote object.

A depth measuring method and system applicable to a first binocular camera having a zoom lens is provided. The method includes: obtaining a current depth of a target object (S101); determining a focus with which the current depth is measured as a current focus (S102); determining, according to the preset correspondence between depth ranges and focuses, a current reference focus corresponding to a current reference depth range; wherein, the current reference depth range is a depth range in which the current depth falls (S103); determining whether the current focus is the same as the current reference focus; (S104); if the current focus is the same as the current reference focus, determining the current depth as the target depth of the target object (S105); or if the current focus is not the same as the current reference focus, adjusting the current focus to the current reference focus, measuring a current depth of the target object with the adjusted current focus (S106), and proceeding to the operation (S103) of determining, according to preset correspondence between depth ranges and focuses, a current reference focus corresponding to a current reference depth range. An object in various depth ranges is measured with a varying focus. The accuracy of the depth measurement of the target object is thus improved.
