With reference to figure 3, can be the data under same Medicine standard manikin 30 by the data reduction such as bone parameter, bone Connecting quantity, skeletal muscle operating mode of tested object 31 and demonstrator 32.Such as, the conversion process of bone parameter can comprise the conversion of stature.
In brief, the conversion process of bone parameter can comprise: calculate bone length with the distance (or being called length) between the bone reference point preset.For identical bone, by the ratio of the bone length of tested object and the bone length of Medicine standard manikin, can by each bone parameter conversion of tested object to the corresponding bone parameter under Medicine standard manikin.
Specifically, can convert according to the stature parameter of Medicine standard manikin to tested object.According to the length ratio relation between both bone reference point, the proportionate relationship data acquisition CD that record is corresponding, shape is as following table.
For joint motion operating mode, the current joint angle of tested object can be obtained percents numerical value divided by after maximum angle scope, calculate according to percents numerical value and the Medicine standard manikin parameter adopted, shape is as following table:
In upper table, for the manner 1 in joint 1, the activity point of view scope (being also maximum activity angle) in the joint 1 of demonstrator is EAR1, the joint 1 of demonstrator is when executed activity mode 1, the current angle position in joint 1 is EAP1, then the angle position of demonstrator is than being EAP1/EAR1, and being scaled to Medicine standard manikin is then EAP1/EAR1*SAR1, and wherein SAR1 is the activity point of view scope of joint 1 when executed activity mode 1 in Medicine standard manikin; And for student, same joint 1 is when performing same manner 1, the activity point of view scope in the joint 1 of student is TAR1, the current angle position in joint 1 is TAP1, then the angle position of student is than being TAP1/TAR1, being scaled to Medicine standard manikin is then TAP1/TAR1*SAR1, and wherein SAR1 is the activity point of view scope of joint 1 when executed activity mode 1 in same Medicine standard manikin.Because the joint states information of same joint (joint 1) under same manner (manner 1) of demonstrator and student is scaled to identical Medicine standard manikin, therefore can contrast without barrier, and there is not the impact of range of motion difference by different human body.
Bone parameter in above-mentioned two cover parameters can convert according to " bone ratio ", after the bone length of tested object changes, range of motion changes, the mode of correction can be adopted to upgrade legacy data.
Adopt such scheme, after the collection of human body narrow sense kinematic system inside cooperation relation, calculating information datas such as obtaining bone parameter, bone Connecting quantity and electromyographic signal, simultaneously match combination can be carried out to the information data obtained.Record the information such as the position of bone corresponding with movement locus information is put, joint motion operating mode, skeletal muscle operating mode, fibrous connective tissue operating mode frame by frame by the final 3D picture that exports, and preserve with relevance array configuration.Each frame is for mating the critical data shape of contrast and chart expression as following table:
