Problems solved by technology

The existing tracking algorithm has a strong dependence on video recognition. Before tracking, it is necessary to calculate the direction and distance of the target through the algorithm, and sometimes it is even necessary to predict the trajectory of the target, which will greatly reduce the tracking detection. The real-time performance affects the accuracy and robustness of motion detection to a certain extent.

Embodiment

[0036] In order to better describe the embodiment, in the embodiment, the feature of the tracked target set by the present invention is: a rectangular sign with a blue background, and there are letters and numbers used to distinguish the target in the blue background. The tracking system is a small car model that can move freely. A small camera is installed on it to obtain image data. The main control board can process the image data obtained by the camera and drive the car to move.

[0037] Embodiments of the present invention include the following steps:

[0038] Step 1: After the tracking system is started, the car starts to autonomously patrol to find the target according to the preset trajectory.

[0039] Step 2: The main control board continuously analyzes the image information captured by the camera while the car is moving. After the main control board reads a frame of image information, in order to reduce the impact of light intensity on the recognition results during...

Abstract

The invention relates to a moving-target progressive locating and tracking method based on water strider food location. The movement locus of a main tracking device is planned by introducing the idea of water strider predation, and therefore, accurate tracking on a moving target is realized, and meanwhile, the pressure of needing to process mass data in video recognition during tracking is reduced and the instantaneity and the accuracy of tracking and detection are improved. The moving-target progressive locating and tracking method based on water strider food location has the advantages of high tracking speed and strong antijamming capability.

Description

technical field [0001] The invention relates to a progressive positioning and tracking method for an intelligent moving target, which can be used for positioning and tracking the moving target in systems such as intelligent avionics, national defense and military industry, and weaponry, and belongs to the technical field of intelligent information processing. Background technique [0002] Water striders are small aquatic insects commonly found in lakes, ponds, paddy fields and wetlands. Adult water strider insects are eight to ten millimeters long, dark brown, with a triangular, slightly longer head. Body small to large, oblong or oval. The muzzle is slightly longer, divided into 3 segments, and the second segment is the longest; the antennae are filamentous, with 4 segments, protruding from the front of the head. The prothorax is elongated, the back is mostly dark and dull, without distinct piebald spots, the forewings are leathery, and there is no membranous part. The v...
