Shown in Fig. 2,3, in this preferred embodiment, adopt 9 probes, be respectively 2,4,1,1A, 3,3A, 2A, 5,6, the relative space position of each probe and corresponding refraction angle are as figure, and for same point object (is example with a screw), car 4 passages, 37 ° of probes forward when the A point can be got to, display graphics on screen, its horizontal level on image is:
X1＝S1*COS37°
S1 is the sound path of the ultrasonic propagation of 4 passages probe in the formula.
Along with advancing of dolly, image constantly refreshes mobile, and when arriving the B point, dolly has moved the distance of L1, and the image correspondence also moves forward L1, and at this moment 37 ° of probes backward of 5 passages are also got to this point, and its horizontal range is:
X2＝S2*COS37°+D1
S2 is the sound path of the ultrasonic propagation of 5 passages probe in the formula, and D1 is the horizontal range of 4,5 passages probe.
Can prove: L1=S1*COS37 °+S2*COS37 °+D1=X1+X2
The picture point that such 5 passages are drawn just and just now overlapped the 4 passages position of point after moving of drawing, so just by space conversion with same some coincidence demonstration, reflected the actual detection situation.
