Wheel Arch Height Measuring Device
Adas Calibration EquipmentThe front eyebrow height measurement sensor (2D camera) sensor uses a laser to measure based on the triangle principle. The position of the linear laser in the sensor and the angle with the camera are fixed after being calibrated. The 635nm red laser irradiates vertically to the highest point of the eyebrow on the front axis plane. After the 2D camera is imaged and identified in the CCD, the software solves the laser line to calculate the turning point, and solves the Y and Z coordinates of the corner point according to the laser triangle principle, where the Z coordinate is the height of the eyebrow.
Product Details
Wheel eyebrow height measuring device
I. Overview
Copyright/IP PolicyBased on the visual inspection scheme, the eyebrow height detection device calculates the distance between the center of the car tire or the ground to the highest point of the body contour arc above the tire, which is mainly used for air suspension calibration and ADAS system calibration.
II. Test Principle
The sensor is measured based on the laser triangulation principle, and the position of the linear laser in the sensor and the angle with the camera are fixed after calibration. The 635nm red laser irradiates vertically to the highest point of the eyebrow on the front axis plane. After the 2D camera is imaged and recognized in the CCD, the software calculates the turning point of the laser line and solves the Y and Z coordinates of the turning point according to the laser triangulation principle, where the Z coordinate is the height of the eyebrow.
