hierarchical.to.direct.kinematic: Generates direct kinematic model from hierarchical kinematic...

In browarsoftware/RMoCap: Package for processing and kinematic analyzing motion capture data.

Description

This function makes calculations based on hierarchical kinematic data in input list (input.skeleton). It does not use Dxyz from input.skeleton.

Usage

hierarchical.to.direct.kinematic(input.skeleton)

Arguments

input.skeleton

list in the same format as one generated with read.mocap function.

Value

data frame with direct kinematic model. Names of the columns are the same as in input.skeleton.

Examples

#an example BVH file
data("heian.nidan.bvh")
f <- file("heian.nidan.bvh")
writeChar(con = f, object = heian.nidan.bvh)
close(f)
#read hierarchical model stored in hierarchical BVH file
heian.nidan <- read.mocap("heian.nidan.bvh")
#plot kinematic data
plot(x = heian.nidan$data.frame$Hips.Dx, y = heian.nidan$data.frame$Hips.Dz, type = "l", ylab = "Displacement X [cm]", xlab = "Displacement Z [cm]")
title("Hips displacement during motion")

#generate kinematic from hierarchical model - same results as above
df <- hierarchical.to.direct.kinematic(heian.nidan$skeleton)
plot(x = df$Hips.Dx, y = df$Hips.Dz, type = "l", ylab = "Displacement X [cm]", xlab = "Displacement Z [cm]")
title("Hips displacement during motion")
