ROFlow - Optical Flow Results

The ROFlow-Sensor produces an optical flow field of 128 × 128 vectors. Data are given as two streams of 8-bit values. One stream corresponds to the x-component of the vector field, the other to the y-component.

Three different methods are offered to visualize the optical flow data:

Corresponding to the input data, two kind of results are given:


as separate images:
x-component y-component

as vector field:


train approaching to an obstacle
optical flow colour reference map

as colour image sequences:
