Before system operation, the target of high reflecting rate (blip point) is attached on scanning means first.Implement herein In example, reference target is the target that surface has retro-reflective characteristic, and pattern is under the luminescence band of polygon lamp group can See, material is surrounded by the ring of antiradar reflectivity color (such as black), and it is accurate in the image of sensor to facilitate tracking device Identify target.Due to using the material with retro-reflective characteristic, the surface of object needs to be illuminated to allow to reference mesh Target appropriately identifies.
The LED projecting unit of tracking device and the LED projection subelement of scanning means are equidistantly made of multiple LED, just Polygonal array is fixed near camera front end, and center is located in camera optical axis and direction is consistent with camera optical axis direction of observation Lamp group realize that label target and/or the light filling of testee illuminate, the intensity of LED light can be adjusted to make mesh in image Mark and background have enough luminance differences, help to accurately identify target in the image of sensor.
In one embodiment, the image sensing cell 114 of tracking device 100 is a pair of of camera, tracking device 100 Image sensing cell may be multiple cameras, and LED projecting unit is fixed between camera, and the 2D for obtaining scanning means schemes Picture.
Due to using circular target label, the non-distortion profile for extracting reflectance target in the picture can use ellipse wheel Exterior feature indicates.Because camera is calibrated, non-distortion profile can be used well known method in fields and be distorted to remove, herein In example, need to obtain the optical property parameter of camera from camera parameter memory.According to the side of the cartouche in image Journey can calculate the orientation of the cartouche in the 3 d space, can be with reference to " to the introductory technology of 3D computer vision The Chapter 11 of (Introductory techniques for 3D computer vision) " is to be discussed in greater detail. Because the circle projects the center of projection of camera, the circle in the 3 d space with conical intersection.Extract profile point it Afterwards, the model being fitted on local 3D point set can be plane or the quadratic polynomial for bigger precision.In the feelings of the latter In condition, least squares method is applied using with drag, then obtains its geometric parameters using common elliptic parameter calculation method Number.

The 3D coordinate calculation of laser pattern and the Coordinate calculation method of above-mentioned target's center are almost the same.In view of list Matching caused by a laser point feature is insufficient needs to press the geometrical characteristic combination of projection pattern according to missing and error hiding, The matching that the point set with geometrical characteristic is calculated by combined result, then reuses the Coordinate calculation method with target's center. In this example, projection pattern is cross spider, therefore uses line segment as matched geometrical characteristic, likewise, using different Pattern is projected, is needed using different feature and combination, principle is consistent.
