Product Description
EM4 is the first product of our new digital architecture EM platform, which integrates advanced technologies such as digital architecture, crosstalk cancellation, full condition optoelectronic signal processing, and data lossless compression.
It has top performance such as up to 1080 lines, a range of up to 600 meters, and an imaging capability of 25.92 million points per second, leading car mounted LiDAR into the era of "thousand lines".
EM4 can provide 1080P high-definition 3D perception capability for cars, accurately identifying small objects such as tires, cones, and paper boxes in the distance.
Compared to the current mainstream LiDAR product EM4, it can increase the response time of intelligent driving systems by up to 70%, making system decision-making more relaxed and providing a safer and more comfortable driving experience.
Million level dense point cloud
EM4 has a 0.1 ° x0.05 ° angular resolution and 6240000pcs/s output points, providing high-definition 3D perception for cars. It can accurately identify small objects such as tires, cones, and paper boxes in the distance, providing the ultimate safety guarantee for robots.
300m ultra long distance measurement
The EM4 features a ranging capability of 300 m (250 m @ 10%), enabling more relaxed system decision-making and helping robots efficiently perform obstacle avoidance, mapping, navigation and other tasks.
Accurately detect small objects in the distance
·High speed throwing
Clear detection of black paper boxes (40x25cm) within 250m, emergency avoidance or braking speed increased to 181km/h (* calculated value)
·White vehicle
Clear detection of white vehicles within 600m, emergency avoidance or braking speed increased to 289km/h (* calculated value)
·Black tires
Clear detection of accidentally scattered tires within 180m, emergency avoidance or braking speed increased to 147km/h (* calculated value)
·Traffic cone bucket
Clear detection of traffic cones within 300m, emergency avoidance or braking speed increased to 200km/h (* calculated value)
Exclusive core technology controls all working conditions
With the support of leading exclusive technology, EM4's high anti expansion suppression, rain, fog, dust and noise removal, anti dirt shielding and other aspects have been comprehensively upgraded, enabling the auto drive system to achieve clear and accurate environmental detection of the whole scene under all working conditions.
High anti inflation inhibition
Fearless of rain, fog, and dust
Anti dirt and water stain blocking
