class sdurw_sensor.Image(*args)

Bases: object

The image class is a simple wrapper around a char data array. This Image wrapper contain information of width, height and encoding.

The image class is somewhat inspired by the IplImage of opencv.

The coordinate system has its origin located at the top-left position, where from X increases to the left and Y-increases downwards.

setting pixel values in an efficient manner has been enabled using some template joggling. It requires that the user know what type of image he/she is working with.

Bases: sdurw_sensor.SensorModel

The Camera class defines a general interface to a stereo camera. A stereo camera consists of two cameras with the same intrinsic parameters, but with different extrinsic parameters.

Since ideal cameras are assumed, the intrinsics are given as a horizontal/vertical pixel resolution as well as a horizontal field of view (FOV).

The extrinsic parameters are given simply as two transformation matrices, which give the pose of the cameras relative some external frame.

the TactileArrayModel describes tactile sensor consisting of arrays of tactile cells that can be placed on a defined shape. The shape is described with a matrix of 3d vertices. Such that tactil (0,0) maps to the quad defined by the four vertices {(0,0),(0,1),(1,1),(1,0)}. Notice that the normal is defined by sequence of the vertices and that the normal defines the direction of tactile sensing.
