Embodiment 1

[0038] An embodiment of the present invention provides a guiding method for image acquisition of a target object, such as figure 1 shown, including the following steps:

[0039] Step S1: Obtain the region of interest of the image of the target object to be detected.

[0040] In the embodiment of the present invention, the target object to be detected is a palm. In machine vision and image processing, the area to be processed is outlined in the form of a box, circle, ellipse, irregular polygon, etc. from the processed image, which is called a region of interest (ROI). In the embodiment, the region of interest is in the shape of a palm, and images of the target object to be detected are collected through image sensors, cameras and other equipment. The acquisition equipment uses various operators and functions on existing image processing software such as Halcon, OpenCV, and Matlab to obtain the ROI of the region of interest in real time, making the acquisition more convenient ...

Embodiment 2

[0050] An embodiment of the present invention provides a guidance system for image acquisition of a target object, such as Figure 6 shown, including:

[0051] The target object acquisition module 1 is used to acquire the region of interest of the image of the target object to be detected; this module executes the method described in step S1 in Embodiment 1, which will not be repeated here.

[0052] The comparison result generation module 2 is used to compare the region of interest of the image of the target object to be detected with the guide map marked by the image library according to the preset image recognition algorithm to generate a comparison result; this module executes the method in Embodiment 1 The method described in step S2 will not be repeated here.

[0053] The guidance module 3 is used to generate position movement guidance information according to the comparison result, and display the position movement guidance information by voice and / or text, and guide th...

Embodiment 3

[0056] An embodiment of the present invention provides a terminal, such as Figure 7 As shown, it includes: at least one processor 401 , such as a CPU (Central Processing Unit, central processing unit), at least one communication interface 403 , memory 404 , and at least one communication bus 402 . Wherein, the communication bus 402 is used to realize connection and communication between these components. Wherein, the communication interface 403 may include a display screen (Display) and a keyboard (Keyboard), and the optional communication interface 403 may also include a standard wired interface and a wireless interface. The memory 404 may be a high-speed RAM memory (Random Access Memory, random access memory), or a non-volatile memory (non-volatile memory), such as at least one disk memory. Optionally, the memory 404 may also be at least one storage device located away from the aforementioned processor 401 . Wherein, the processor 401 may execute the guiding method for im...

Abstract

The invention discloses a target object image acquisition guiding method and system. The method comprises the steps of obtaining a region of interest of a to-be-detected target object image; accordingto a preset image recognition algorithm, comparing the region of interest of the to-be-detected target object image with a guide map calibrated by an image library to generate a comparison result; and generating position movement guide information based on a comparison result, and displaying the position movement guide information through voice and/or characters to guide a user to complete imageacquisition of the to-be-detected target object. A hardware guiding device is replaced by software, so that a user can be conveniently, quickly and intelligently guided to acquire an image of a targetregion of interest.

Description

technical field [0001] The invention relates to the technical field of biometric identification, in particular to a guiding method and system for image acquisition of a target object. Background technique [0002] Biometric technology is a technology for identifying people based on their inherent physiological or behavioral characteristics. Those that have been used include fingerprint recognition, iris recognition, palm geometry recognition, retina recognition, face recognition, signature recognition, voice recognition, etc., and the corresponding biometric features include hand shape, fingerprint, iris, face shape, retina, pulse, Auricles, etc. Behavioral characteristics include signature, sound, and key pressure. Biometric technology can be widely used in government, military, bank, social welfare, e-commerce, security and defense. [0003] Vein recognition is a kind of biometric recognition. When performing vein recognition, the vein image of the palm must be collected...
