Benewake have officially released the first 512-line automotive-grade lidar, the AD2. It’s a 905-nanometre unit, scheduled to achieve mass production and delivery in 2023.
CEO Li Yuan says “Lidar can identify at 100m distance if it is a person or a car, but at 200m, the vehicle and the person’s movements are no longer distinguishable”. The 512-line vehicle-level lidar released by Benewake has a field of view of 120° × 25.6°, and a longitudinal resolution of 0.05°, which can detect targets of similar size at the height of flat tires from 120 metres away, or accurately restore the silhouette or even gait of a person at a distance of 200 metres.
In addition, the AD2 also realises high-definition detection in all angles and areas, and the high resolution in the entire viewing angle is coherent and smooth—without overlapping; interlacing; gaps, or other such crudities. To achieve such high resolution, Benewake leveraged many innovations in optical design; scanning accuracy; signal processing; automatic calibration and assembly, and more. Based on these innovations, the AD2 is just 135 × 195 × 55 mm.
By using semiconductor laser and sensor array transceiver technology, as well as proprietary innovative laser driver circuitry and receive signal processing circuitry, the AD2 greatly improves the dynamic range and reduces the noise in the signal.
