High-Precision Optically-Guided ADAS Calibration & Positioning System, Dual-Mode Static & Dynamic Calibration Device For Full-Vehicle Perception Sensors
This full-range compatible intelligent ADAS calibration and positioning system is a new-generation comprehensive calibration equipment specially developed for modern intelligent connected vehicles and high-level autonomous driving vehicles. It deeply integrates five core technologies including 3D laser positioning, high-definition binocular vision imaging, artificial intelligence algorithm operation, high-precision optical ranging and dynamic error compensation. It solves the common industry problems of traditional single-function calibration devices, such as limited functions, insufficient positioning accuracy, narrow vehicle compatibility and fixed deployment modes. Combining two core functions of vehicle four-wheel alignment detection and advanced driver assistance system sensor calibration, it realizes multi-purpose application, integrated workflow and data interconnection, serving as an innovative comprehensive solution different from ordinary ADAS calibration equipment on the market. Fully optimized for the diversified development trend of the automotive industry, the system is compatible with not only traditional fuel passenger cars, but also sedans, SUVs, MPVs, large passenger buses, heavy commercial trucks, engineering special vehicles, battery electric vehicles, plug-in hybrid vehicles and all types of intelligent vehicles equipped with L2 to L4 high-level autonomous driving systems.
Description
The entire ADAS calibration and positioning system adopts a dual technical framework of full-range laser positioning and optical vision calibration, which is fundamentally different from traditional pure mechanical alignment and simple image recognition equipment, greatly improving positioning benchmark accuracy and calibration stability. Equipped with multiple sets of high-power directional laser transmitters, the device builds cross reference laser lines, central positioning laser surfaces and distance measuring laser groups. It can automatically complete the positioning of the vehicle central axis, horizontal height of the calibration area and front & rear reference distance, completely replacing extensive manual operations such as tape measuring and visual alignment, with the positioning benchmark error controlled at the micron level.
Combined with multiple industrial high-definition cameras and optical sensors, it forms a binocular stereo vision acquisition network to capture target patterns, sensor images and vehicle chassis posture data in real time. Built with deeply optimized AI image processing algorithms, 3D spatial coordinate conversion programs and dynamic ground compensation algorithms, the system automatically eliminates external interferences including uneven workshop floors, lift vibration, ambient light changes and dust.
It supports two technical modes: static calibration and dynamic calibration. The static mode is applicable to daily maintenance in workshops, calibration after accident vehicle repair and reset after component replacement. The dynamic mode realizes calibration under simulated road conditions, meeting the commissioning requirements of full-scenario perception sensors for high-level autonomous vehicles. In terms of data interaction, the system connects the data links of the four-wheel alignment module and ADAS calibration module. Chassis alignment data can be directly synchronized to the sensor calibration program, forming a standardized workflow of "alignment first, calibration later", and fundamentally preventing ADAS calibration failure caused by wheel posture deviation. The whole technical process features high automation, no repeated adjustment of equipment benchmarks or manual parameter checking, which greatly reduces operation difficulty and ensures data consistency and accuracy during long-term continuous work.
