Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto. Such as figure 1 As shown, the infrared dynamic high-resolution non-contact respiration measurement system is composed of an infrared structured light projection module M1, a data acquisition module M2, and a high-performance computer D3. The steps are as follows:

[0019] 1. Through N infrared projection devices D1 parallel to the same optical horizontal plane in the structured light projection module M1 1 to D1 N The structured light pattern P1 is projected onto the target object, and the projection direction is the abdomen and back direction of the human body H to be measured. Preferably, N is 3; the structured light pattern P1 is a two-dimensional coded pattern generated in advance. Preferably, the pattern has a passing wavelength of 920 - Randomly distributed low-densi...

Abstract

In order to solve the problems that when an existing non-contact type three-dimensional measurement system is applied and respiratory monitoring is carried out, the resolution ratio and the frame rate are difficult to consider at the same time, and wearing is tedious, the invention discloses an infrared dynamic high-resolution non-contact type respiratory measurement system. The infrared structured light and a multi-frame super-resolution algorithm are utilized to perform high-precision three-dimensional reconstruction on the chest and abdomen in a non-contact manner under the condition of ensuring a certain frame rate, and the key point recognition algorithm is utilized to automatically recognize the left and right chest and abdomen wall boundaries of the human body, so that the respiration conditions of the left and right lungs and the whole lung can be simultaneously analyzed, and the whole measurement process is simple and efficient.

Description

technical field [0001] The invention relates to a dynamic three-dimensional measurement system, in particular to an infrared high-resolution dynamic three-dimensional measurement system. Background technique [0002] Respiration is an important way for human beings to obtain oxygen and expel carbon dioxide to maintain the vitality of the body. By monitoring the breathing signal, the lung function status of a person can be evaluated. However, currently, the measurement of respiratory signals mostly adopts a contact measurement method: the sensor is connected to the human body to collect respiratory signals. Although more accurate measurement parameters can be obtained, the equipment is relatively complicated, which brings some inconvenience to clinical treatment. In addition, wearing the detection device for a long time will hinder the patient's activities and the detection at home, and may even cause the patient's anxiety. Mood changes and physical discomfort. In addition...
