AI Technical Summary

Problems solved by technology

The existing problems are (1) Obtaining the profile of a person through edge detection cannot guarantee a very accurate profile; (2) Some studies have shown that the reliability of identification based on structural features is poor, while the reliability of identification based on statistical features sex is better
The existing human ear recognition technology is generally based on the human ear image captured by the camera. One problem is that it is difficult to accurately locate the ear area in the image.

Embodiment Construction

[0030] The system flow chart of the identification device combining the side profile and human ear features proposed by the present invention is as follows: figure 1 As shown, the specific implementation steps are as follows:

[0031] Step 1: Image Acquisition

[0032] Image acquisition is the basis for subsequent recognition. Channel-based acquisition can be used for acquisition, such as figure 2 As shown, when acquiring an image, the user only needs to stand in front of the camera, and the system judges whether the image is suitable for recognition based on the captured image. If it is not suitable, the camera will be automatically moved until the captured image is suitable for recognition; Using hand-held acquisition methods, such as image 3 As shown in FIG. 1 , other people or themselves directly hold the image acquisition device to acquire ear images, and prompt the direction of manual operation in the form of a beep until an image that can be used for identification...

Abstract

A status identification device by combining side outline with human ear character is prepared as adjusting video camera to obtain clear image of human face side by image obtaining unit according human ear position, detecting out side outline of human face by calculation unit according to obtained image, making rough classification as per side outline, confirming accurate position of human ear by using side outline based on result of rough classification then making precise classification by utilizing human ear character for realizing status identification.

Description

technical field [0001] The invention belongs to the personal identification technology based on human biological characteristics, and in particular relates to the measurement and combination recognition of human ear characteristics and human face profile characteristics. Background technique [0002] Identification is a problem that people often encounter in modern society. For example, identification is required in places that require security inspections such as banks, public security, online shopping, shopping malls, and living quarters. Biometric recognition technology uses human-specific physiological (Physiological) or behavioral (Behavior) characteristics for automatic identification and verification. It is an important technical means to realize intelligent social security and military security. Especially after the 9.11 incident in the United States, the governments of various countries have paid more attention to the security of anti-terrorism in public places, an...
