The cameras use one of several different techniques to sense a car's position, including video motion sensors, laser tracking and sensors embedded in the road.
[145] demonstrated the use of a multi-sensor, laser scanning method for the detection of cracks by fusing laser line scanned data with video to produce a 3D model of a road surface which identified cracks of a few cm as well as their depth.
It harnesses sensors, laser, radar and stereoscopic cameras to offer semi-autonomous driving.

In this context, classical sensors are limited due to the technologies used: ultrasound is perturbed by wind, optical sensors (laser, vision) by rain, fog or the presence of dust or by poor lighting conditions.
The assessment was accomplished by means of an experimental survey carried out on seven different monitoring technologies: Inductive loops WIM (Weight In Motion) based on piezoelectric sensors WIM (Weight In Motion) based on quartz sensors Image recognition (video systems) Double technology (radar and laser sensors) Triple technology (radar, passive and ultracoustic sensors) Laser technology.
To enable a robot to navigate through an environment autonomously, an estimation of its position within a reference system or map could be obtained from sensors, such as dead-reckoning sensors, laser sensors, radar sensor or 3D camera sensors [6], GPS (Global Positioning System) [1, 3, 10, 19, 30].
Our study is the first to demonstrate indirect calorimetry technology the combines thermal mass flow sensors, laser diode absorption O2 analyzers, and infrared spectroscopy CO2 sensors to assess metabolic outcomes in rat pups as young as 2 days.
The cars, which are being developed by Google, rely on video cameras, radar sensors, lasers and a database of information collected from manually driven cars to help navigation.
That amount of power can supply external sensors, lasers, LEDS, imaging sensors, motors, you name it.
