Embodiment Construction

[0025] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is said to be "fixed" to another element, it may be directly on the other element, or there may be one or more intervening elements therebetween. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or one or more intervening elements may be present therebetween. The orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", and "bottom" used in this specification is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the The invention and the simplified description do not indicate or imply that the device or element referred to must have a specific orientation...

Abstract

The invention relates to the technical field of unmanned aerial vehicle tracking, in particular to a target tracking method and device of an unmanned aerial vehicle and an image processing chip. The method comprises the following steps of identifying a target image returned by an unmanned aerial vehicle, calculating a first identification result from the target image, conducting score comparison on the identification boxes in the second identification result and all the identification boxes in the first identification result, and constructing and screening out a target list with the highest conformity, calculating a relative offset direction of each identification box in the target list, determining a target device between the target image and the previous frame of target image as an optimal matching relationship, and tracking a plurality of target devices in the target image. By applying the target tracking method provided by the embodiment of the invention, real-time tracking of the specific target device can be kept in the inspection process and in the process that the unmanned aerial vehicle pan-tilt camera turns to the specific target device, and photographing is performed when the specific target device appears in the center of the picture, so that the imaging quality of the inspection picture is improved, and the imaging quality of the inspection picture is improved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle tracking, in particular to a target tracking method, device and image processing chip of an unmanned aerial vehicle. Background technique [0002] With the continuous development of UAV technology, the application range of UAVs is becoming wider and wider. The application of UAVs in the inspection of power system transmission lines has been fully launched, and it is changing from manual UAV inspections to fully automatic UAV inspections. Humanized inspection changes. [0003] In the process of realizing the present invention, the inventor found that while the automatic inspection of the UAV improves the inspection efficiency, due to problems such as the position control accuracy of the UAV and the GPS positioning accuracy, in the inspection photos taken by the UAV, The target device being photographed is not in the center of the screen, but at the edge of the screen, which affects...
