The footprint method is a method of making a foot print when the foot is soaked in water and walks on a dry plane, or making a foot print on white paper by applying ink to the sole of a foot. This approach can only evaluate two-dimensional images, and has many limitations. Later, the method of detecting the marks or traces left by the human feet on the easily deformable substances such as gypsum, mud, sand, rubber and the like is developed. This approach may present a rough three-dimensional morphology of the foot, but lacks presentation on the foot data. The sensor type pressure plate is a test system developed on the basis of a transducer and a sensor. The gait analysis system instrument can test the plantar pressure value, convert the plantar pressure value into an image, visually evaluate the stress condition through the color depth of the image, accurately check the pressure value of a certain part according to the feedback value of the unit sensor, and is affected by the density and the repeated consistency of the pressure sensor, and the measurement result is not as accurate as an optical plantar pressure detection scheme. The optical plantar pressure detection can accurately measure the foot pressure distribution, and the foot pressure distribution is measured through an optical image, so that the arch type, the pressure distribution, the state of the sole, the heel and the navicular bone are analyzed. The method can be widely applied to the field of rehabilitation medical human body exercise science, and is a simple and effective rehabilitation method which is widely accepted by foot medical professionals worldwide at present by carrying out quantitative analysis on foot pressure distribution and combining an analysis system to provide professionals for pre-operation and post-operation evaluation, injury detection, drug research evaluation and exercise medical scientific research evaluation. And the bone morphology of the ankle and knee parts of the human body is obtained, and a large-scale X-ray or CT device is generally used for scanning. The whole detection process has radiation and injury to human bodies, the optical detection can be used for carrying out static image capturing and 3D development through the optical image, and the bone morphology of ankles and knee parts can be analyzed by combining a modeling imaging technology, so that the method can be widely applied to the field of rehabilitation medical human body sports science, and is a simple and effective rehabilitation method recognized by current medical professionals through quantitative analysis of ankles and knee parts, pre-operation and post-operation evaluation, injury detection, drug research evaluation and sports medical scientific research evaluation by combining an expert system.

However, the optical plantar pressure image acquisition instrument in the existing market is generally large in size, heavy in shape and incapable of simultaneously acquiring multiple types of optical images of ankle and knee parts, so that the novel ankle and knee multi-mode optical image acquisition instrument and detector which can simultaneously acquire images of the sole, ankle, shank and knee and are convenient for an acquired person to use, small in structure and portable in moving arrangement are designed to be the research direction.
