Embodiment 1

[0046] see figure 1 As shown, it is a flow chart of the method for locating a target object in an image provided by the first embodiment of the present invention. According to different requirements, the order of the steps in the flowchart can be changed, and some steps can be omitted.

[0047] Step S1, acquiring an image to be recognized.

[0048] In one embodiment of the present invention, the image information of the image to be recognized collected by the photosensitive element is acquired by the processor in the imaging device. In other implementation manners, the image to be recognized may also be obtained from other storage media.

[0049] Step S2, identifying at least one target area in the image to be recognized, and marking the target area to obtain at least one marked area, wherein the area of ​​the marked area is greater than or equal to the area of ​​the target area, and the The target area is located within the marking area.

[0050] In an embodiment of the p...

Embodiment 2

[0078] Image 6 It is a structural diagram of a preferred embodiment of the target object locating device in the image of the present invention.

[0079] In some embodiments, the object-in-image locating device 10 runs on a computer device. The device 10 for locating the target object in the image may include a plurality of functional modules composed of program code segments. The program codes of each program segment in the device for locating the target object in the image 10 can be stored in the memory of the computer device, and executed by the at least one processor to realize the function of locating the target object in the image.

[0080] In this embodiment, the device 10 for locating the target object in the image can be divided into multiple functional modules according to the functions it performs. refer to Image 6 As shown, the functional modules may include: an acquisition module 101 , an identification module 102 , a processing module 103 , a search module 10...

Embodiment 3

[0110] Figure 7 It is a schematic diagram of a preferred embodiment of the computer device of the present invention.

[0111] The method for locating the target object in the image in the present invention is applied in the computer device 1 . The computer device 1 may be an electronic device installed with software for locating objects in an image, such as a personal computer, a server, etc., wherein the server may be a single server, a server cluster, or a cloud server.

[0112] The computer device 1 includes a memory 20 , a processor 30 and a computer program 40 stored in the memory 20 and operable on the processor 30 , such as a program for locating objects in images. When the processor 30 executes the computer program 40, it realizes the steps in the embodiment of the method for locating the target object in the image above, for example figure 1 Steps S1-S5 are shown. Alternatively, when the processor 30 executes the computer program 40, it realizes the functions of e...

Abstract

The invention provides a method for positioning a target object in an image, a device for positioning the target object in the image, a computer device and a computer storage medium. The method comprises the steps of obtaining a to-be-recognized image; recognizing at least one target area in the to-be-recognized image, marking the target area to obtain at least one marked area, the area of the marked area being greater than or equal to the area of the target area, and the target area being located in the marked area; carrying out binarization processing on the mark area, wherein the color of the pixel points of the target area after binarization processing is different from the color of the pixel points outside the target area; recognizing boundary pixels of the target area and effective pixels in the target area in the marked area; and determining and outputting the center and the size of the target area according to the positions of the boundary pixels and the effective pixels. Through the method, positioning of the target object in the image can be carried out in a more intelligent and faster mode.

Description

technical field [0001] The invention relates to the field of locating target objects in images, in particular to a method for locating target objects in images, a device for locating target objects in images, a computer device and a computer storage medium. Background technique [0002] With the development of image recognition technology, image recognition technology has been applied to all aspects of production and life. For example, a camera device can automatically identify and precisely locate a person's face when taking a photo. In order to obtain a better recognition effect, the camera equipment needs to calibrate the positioning ability of the object to be recognized before leaving the factory. In the existing production process, the object to be recognized by the camera device is often positioned by manual calibration. The method has low accuracy and slow speed. Contents of the invention [0003] In view of the above, it is necessary to propose a method and devi...
