The specifications for the laser system were drawn up by TCT. | |||
The system software was developed by local company Radar Vision, which sourced the laser from Europe. | |||
The sensor is a Class 1 laser device that emits infrared light invisible to humans and has an operating temperature range of -10C to 70C. | |||
The system scans the roadway 50 times per second, taking a measurement every 0.5 degrees. The sensor reports distance in millimetres for each measurement. | |||
The road is 6,600mm vertically below the sensor, while traffic with a height above 500mm from the road surface is recognised. | |||
The sensor measures vehicles up to 5.8m in height, and 8.5m of the road’s width. | |||
The system controller does all the calculations to determine which lane every detected point is in. | The system controller does all the calculations to determine which lane every detected point is in. | ||
