Description

Multi-mode optical image acquisition instrument and detector for ankle and knee

Technical Field

The invention belongs to the field of image acquisition and detection equipment, and particularly relates to a multi-mode optical image acquisition instrument and a multi-mode optical image detection instrument for ankles and knees.

Background

At present, the methods can be classified into a foot print method, a sensor type pressure plate, and an optical type plantar pressure detection method according to the development process and the application technology of plantar pressure measurement. The foot printing method is a method of leaving marks on feet when the feet are wet and walk on a dry plane, or smearing ink on soles and leaving foot prints on white paper. This approach can only evaluate two-dimensional images and has many limitations. Later, the way of detecting foot prints or traces left on easily deformable substances such as plaster, mud, sand, rubber and the like by human feet is developed. This approach may present a rough three-dimensional form of the foot, but lacks presentation on the foot data. The sensor type pressure plate is a testing system developed on the basis of a transducer and a sensor. The gait analysis system instrument can test the pressure value of the sole and convert the pressure value into an image, the stress condition can be visually evaluated through the color depth of the image, the pressure value of a certain part can be accurately checked according to the feedback value of a unit sensor, but the measurement result is influenced by the density and the repeated consistency of the pressure sensor, and the measurement result is not as accurate as that of an optical sole pressure detection scheme. The optical plantar pressure detection can accurately measure the pressure distribution of the foot, and the foot pressure distribution is measured through optical images, so that the types of the foot arches, the pressure distribution and the states of the sole, the heel and the navicular bones are analyzed. The foot pressure distribution quantitative analysis method can be widely applied to the field of rehabilitation medical human motion science, and is a simple and effective rehabilitation method recognized by foot medical experts all over the world at present by providing experts for pre-and-post-operation evaluation, injury detection, drug research evaluation and sports medicine scientific research evaluation through the quantitative analysis of the foot pressure distribution and the combination of an analysis system. The bone morphology of the ankle and knee of the human body is obtained, and the bone morphology is generally scanned by using a large-scale X-ray or CT device. The whole detection process can radiate and damage human bodies, optical detection can acquire 3D development through dynamic and static images through optical images, the skeletal shapes of the ankle and the knee parts can be analyzed by combining a modeling imaging technology, the method can be widely applied to the field of human body motion science of rehabilitation medicine, quantitative analysis is carried out on the ankle and the knee parts, and pre-and post-operation evaluation, damage detection, medicine research evaluation and sports medicine scientific research evaluation are carried out by combining an expert system, so that the method is a simple and effective rehabilitation method acknowledged by medical experts at present.

However, the optical plantar pressure image acquisition instrument in the existing market is generally large in size, heavy in body and incapable of acquiring various types of optical images of the ankle and the knee part at the same time, so that the optical plantar pressure image acquisition instrument designs a novel ankle and knee multi-mode optical image acquisition instrument and a novel ankle and knee multi-mode optical image detection instrument which can acquire images of the sole, the ankle, the calf and the knee at the same time, are convenient to use by an acquirer, are small in structure and convenient to move and arrange, and become the research direction.
