Embodiment Construction

[0026] attached figure 1 The state of the single-multi-eye real-time positioning measurement system for moving targets shown includes five states: calculation waiting, target initialization, multi-eye positioning measurement, monocular positioning measurement, and target position prediction. The system performs state transition according to the current state, the number of cameras that detect the target, and the predicted time.

[0027] 1. Calculation waiting and target initialization

[0028] In the calculation waiting state, the positioning measurement of the target is not performed, and the circular method is used to continuously detect whether there is a target in the images of each camera in real time. Once the target is found, it will immediately enter the target initialization state.

[0029] The target initialization state marks the target, initializes the target measurement information database and other tasks. Make a mark for the newly appeared object, establish a ...

Abstract

The invention provides a real-time single and multiple object optimized positioning method for moving objects. The method comprises system states including calculation waiting, object initialization, multi-object positioning measurement, single-object positioning measurement and object position prediction; the measurement state is optimized or changed according to object search, multi-object tracking measurement, single-object tracking measurement and transient object loss conditions and the like; different measures are used to position the moving objects; the measurement information is fully utilized, the positioning precision is improved, and the measurement continuity is ensured as possible; and real-time optimized positioning measurement for the objects is realized.

Description

technical field [0001] The present invention relates to technical fields such as camera measurement, moving target positioning, etc., and in particular refers to a real-time positioning method for moving targets using single and multiple eyes, and a real-time optimization process for target positioning using a state transfer method according to measurement conditions. Background technique [0002] Moving target positioning has important applications in fields such as battlefield target reconnaissance, attack and defense, and aircraft test measurement and control. Relying on radar to emit electromagnetic waves and receive target echoes to achieve target positioning is the main way to locate moving targets at present, but radar detection is an active measurement, and it is easy to be discovered and counterattacked by the opponent in battlefield confrontation. Video camera measurement uses camera imaging to determine the target position. It is a passive measurement with high pr...
