Sensor parameters used for experiments.

Sensor Parameters	Descriptions
b = 7 cm	Baseline between the camera and each laser line diode
α = 70°	Projection angle of diodes, L1 and L2
β = 96.5°	Projection angle of diodes, L3 and L4
ε1 = 5 pixels	Acceptable boundary of the line parameter ρ for the same line
ε2 = 5°	Acceptable boundary of the line parameter θ for the same line
