Background technology

Fig. 1～Fig. 4 is the distance measuring system and method for TaiWan, China bulletin I289196 patent of invention, it is one to utilize in digitized video the relation of pixel value and distance to carry out the distance measuring system of distance measuring, it is existing functional block diagram with reference to Fig. 1, it is to project a laser beam in the surface of an object 30 with a LASER Light Source 20, an image frame information is captured again with a digital camera 10, and the pixel value of this image frame information is calculated with a computing unit 40, with utilize the proportionate relationship of pixel value and distance converse object 30 length or with the distance of this digital camera 10.

With reference to the schematic diagram of Fig. 2 to be existing distance measuring system with pixel value measure distance, this digital camera 10 is respectively at the position pick-up image picture information of CD straight line and EF straight line, and this LASER Light Source 20 project a bright spot, wherein respectively at CD straight line and EF straight line:

The optics initial point of OP: digital camera 10；

PD, PF: LASER Light Source 20 is respectively at the projection bright spot of CD plane and EF plane；

The plane of scanning motion central point of O: digital camera 10 shooting；

HD: this CD plane and the distance on digital camera 10 surface；

HF: this EF plane and the distance on digital camera 10 surface；

HS:OP and the distance on digital camera 10 surface；

The actual maximum shooting length that DD, DF: digital camera 10 can shoot in CD plane and EF plane；

Dr:PD, PF and the distance of O point；

The maximum shooting angle of 2 θ max: this digital camera 10；

The maximum shooting pixel value of Nmax: digital camera 10 single scanning line；And

ND, NF:PD and PF are respectively to the pixel value of distance of O.

Perspective drawing with reference to the image capture that Fig. 3 is this digital camera 10.Wherein, Z axis is the image capture direction of the optics initial point OP of this digital camera 10, and this digital camera 10 i.e. carries out image capture along Z-direction, and obtains the image frame information of the plane of scanning motion just like the plane comprising A point and B point.And this Z-direction is also the normal direction of this plane of scanning motion, and this Z axis pass through this plane of scanning motion be a little O point, be also the central point of this plane of scanning motion.C point to the straight line of D point and E point to the straight line of F point is in one scan plane the scan line intersected with O point, and the O point on each plane of scanning motion is i.e. positioned at the position of pixel of 1/2.Nmax of each scan line.

Multiple with reference to Fig. 2, the laser beam that this LASER Light Source 20 is projected is parallel to each other with the image capture direction of this digital camera 10, the laser beam making this LASER Light Source 20 must be perpendicular to arbitrary plane of scanning motion of this digital camera 10, and this laser beam is in all identical with the O of this plane of scanning motion point holding distance (Dr) of the projection bright spot (PD, PF) of the plane of scanning motion.

Utilize projection bright spot and the O equidistant characteristic of point of this LASER Light Source 20 so that utilize single LASER Light Source (LASER Light Source 20) to replace traditional two group LASER Light Source, obtain an identical horizontal range (Dr) in arbitrary plane of scanning motion.And there is linear ratio relation the sweep time of the image frame information captured by digital camera 10 with scanned horizontal range, therefore this computing unit 40 just directly can represent scanned horizontal range with the size of pixel value, such as following equation:

$D_D=\frac{N_{\max }}{N_D}\×D_r$

$D_F=\frac{N_{\max }}{N_F}\×D_r$

Below equation can be obtained with reference to triangle theorem:

$H_D=\frac{1}{2}{D}_D\cot {\mathrm{\θ}}_{\max }-h_s$

$H_F=\frac{1}{2}{D}_F\cot {\mathrm{\θ}}_{\max }-h_s$

The proportionate relationship of above-mentioned pixel value Yu horizontal range is brought into triangle theorem and can obtain below equation:

$H_D=\frac{1}{2}(\frac{N_s\left(\max \right)}{N_D}\×D_r)\×\cot {\mathrm{\θ}}_{\max }-h_s$

$H_F=\frac{1}{2}(\frac{N_s\left(\max \right)}{N_F}\×D_r)\×\cot {\mathrm{\θ}}_{\max }-h_s$

Wherein, cot θ max, hs bis-parameter value can go out this cot θ max, the size of hs bis-parameter value via a computation model calculated in advance.Therefore according to the size of such parameter value, this computing unit 40 can try to achieve the value of HD, HF after counting ND, NF value.

With reference to the system architecture diagram that Fig. 4 is the computation model calculating cot θ max, hs bis-parameter value.This computation model includes the vertical gage 41 of this digital camera 10, two groups and two groups of horizontal gages 42.Wherein, such horizontal gage 42 vertical dimension with the surface of this digital camera 10 respectively is hm1, hm2, and such vertical dimension hm1, hm2 can be measured by such vertical gage 41 easily.And in order to increase the accuracy that hs measures, in the model calculating parameter value, be the maximum angle 2 further shrinkage limit of θ max that this digital camera 10 can be shot be 2 θ s, the edge of this plane of scanning motion captured by digital camera 10 the most removable, avoid the generation of fuzzy edge, to increase the accuracy measured.

With reference to Fig. 4, when the maximum shooting angle of this digital camera 10 is limited to 2 θ s, this digital camera 10 also can be measured by such horizontal gage easily in the maximum horizontal shooting distance of such horizontal gage 42, respectively Dm1, Dm2.Following equation can be obtained according to triangle theorem:

$h_s+h_{m1}=\frac{1}{2}{D}_{m1}\cot {\mathrm{\θ}}_s$

$h_s+h_{m2}=\frac{1}{2}{D}_{m2}\cot {\mathrm{\θ}}_s$

Being arranged by above-mentioned formula, the relational expression that i.e. can get cot θ s is as follows:

$h_{m1}-h_{m2}=\frac{1}{2}(D_{m1}-D_{m2})\cot {\mathrm{\θ}}_s$

$\cot {\mathrm{\θ}}_s=2\frac{h_{m2}-h_{m1}}{D_{m2}-D_{m1}}$

And Dm1, Dm2 can be also that the value corresponding to 2 θ max substitutes into above-mentioned relation formula and learns to calculate with this digital camera 10 in maximum shooting angle by relation above formula by the size of parameter value cot θ max again.Further the relational expression of above-mentioned cot θ s is arranged, can be obtained relationship below:

$\frac{h_s+h_{m2}}{h_s+h_{m1}}=\frac{D_{m2}}{D_{m1}}$

Therefore the size of parameter value hs can be obtained:

$h_s=\frac{h_{m1}{D}_{m2}-h_{m2}{D}_{m1}}{D_{m1}-D_{m2}}$

Secondary person, another kind of measuring tool is laser range finder, it is to use LASER Light Source to send modulation light to object, utilize this object reflected laser signals to laser pickoff, common laser pickoff is an Avalanche Photodiode (AvalanchePhotoDiode, APD), optical signal is changed into the signal of telecommunication by it, utilize this reflected signal received can calculate the distance of object, its principle: Td=2L/C represents, wherein, Td refers to launch pulse signal and return pulse signal time delay between the two, L refers to the distance of object to be measured, C refers to the transmission speed of light.Being event, measure Td time delay, distance L of object the most to be measured is the most available.
