Embodiment 1

[0039] see figure 1 , figure 2 A device for collecting and processing multimodal facial images, comprising an industrial computer for collecting and processing images, a diffuse reflection light source for providing a light source for image collection, and a face bracket for providing a reference face position for a collector.

[0040] The industrial computer of this embodiment includes a box body 1, an industrial computer mainboard for processing human face images, a visible light camera 2 and an infrared camera 3 for collecting human face images electrically connected to the industrial computer mainboard are installed in the box body 1 , a plurality of fans for heat dissipation, an antenna for data transmission connected to the motherboard of the industrial computer, the visible light camera 2 and the infrared camera 3 are arranged side by side, and the positions of the visible light camera 2 and the infrared camera 3 corresponding to the box body 1 are all A through hole ...

Embodiment 2

[0044] see image 3 , a face multi-modal image acquisition and processing method, the steps comprising:

[0045](1) Visible light camera and infrared camera are used to collect face images respectively, and visible light face images and infrared face images are obtained.

[0046] (2) The image registration module aligns the visible light face image and the infrared face image obtained in step (1) in spatial position;

[0047] Wherein the image registration steps of the image registration module include:

[0048] Perform human-computer interaction on the images collected by the visible light camera and infrared camera, mark the position of feature points, realize the matching of feature points, and calculate the geometric transformation relationship between the two images; specifically, the shooting object used is heated perforated stainless steel board, such as Figure 4 As shown, the geometric transformation relationship adopted is homography transformation. Homography tra...

Abstract

The invention discloses a face multimodal image acquisition and processing device and method. The face multimodal image acquisition and processing device comprises a box body; an industrial personal computer main board for processing face images, as well as a visible light camera and an infrared camera which are used for collecting the face images and are electrically connected with the industrialpersonal computer main board are installed in the box body; the visible light camera and the infrared camera are arranged side by side; through holes corresponding to the visible light camera and theinfrared camera are formed in the box body; the industrial personal computer main board comprises a control module; the control module is connected with an image registration module for aligning visible light images collected by the visible light camera with infrared images collected by the infrared camera, a color correction module for normalizing the colors of the collected face images, a faceidentification module for precisely positioning a face region, and a face region segmentation module used for segmenting the face region so as to put the temperature of each area into statistics.

Description

technical field [0001] The invention belongs to the technical field of image acquisition and processing, and relates to a face multi-modal image acquisition and processing device and method for health diagnosis. Background technique [0002] With the development of modern society and the improvement of living standards, people pay more and more attention to their health. There are more and more ways for people to participate in medical examinations, and taking thermal infrared images has become an emerging way. Infrared is a band of electromagnetic waves, which is characterized by obvious thermal effects. The human body radiates infrared rays with a wavelength range of 5-50 μm through the skin. The passive infrared camera receives the signal, converts the infrared signal into an electrical signal through photoelectric conversion, and stores it in the computer. [0003] Image registration is to find the mapping relationship between images in space, and estimate the relative...
