Based on the three-dimensional artificial plotting unit of beam radar and high-definition camera, this device is divided into front-end and back-end two parts; Front end comprises: accurate positioning cradle head, beam radar, motorized zoom lens, light filling lamp, and aforementioned four parts connect the high definition web camera; The rear end comprises simulation system and PC; Front end is connected by transmission line with simulation system by the high definition web camera to the rear end.
Described transmission line is a grid line; Separate unit is a cross spider, and many are the switch connection.
Adopt such scheme, beam radar and video camera are installed on the accurate positioning cradle head, the monitor objects that guarantees video camera is consistent with measured object direction, the measurement data of beam radar (distance that is converted out by the mistiming) shows to the software interface of PC by Network Transmission by the RS485 duplex input port of RS485 transmission high-definition camera.
Because precisely the rotational angle position of The Cloud Terrace is that field angle that can read, motorized zoom lens is fixed, so when object distance (radar predicts) is known, can converses height in kind, can converse the dimension of object of real scene according to the two-dimentional icon spacing in the video pictures under a proportional relationship according to trigonometric function relation.
The utility model solves the problem that can not reflect the scene size in the conventional video monitoring, can be used as the reference method of video image mapping geography information.

Embodiment:
Below in conjunction with drawings and Examples the utility model is described in further detail.
Consult shown in Figure 1ly, described three-dimensional drawing system based on beam radar and high-definition camera is divided into front-end and back-end two parts.Front end comprises: accurate positioning cradle head 1, high definition web camera 2, beam radar 3, motorized zoom lens 4, light filling lamp 5; The rear end comprises simulation softward system 6 and PC.Front end is connected with simulation softward system 6 by high definition web camera 2 to the rear end, and transmission line is a grid line, and separate unit can be used cross spider, and many are used switch to connect.
Its principle of work following (consulting Fig. 2-4):
In the simulation softward on PC image is controlled, controlled accurate The Cloud Terrace rotation, motorized zoom lens zoom, obtain the target video picture of high-resolution by network communication.
Carry out the range finding of current location by software remote opening beam radar 3, the range data of beam radar is passed to the RS485 duplex input port of high definition web camera 2 by the RS485 form, shows for the software of rear end by the high definition web camera by Network Transmission;
Precisely the zoom of the rotation of The Cloud Terrace and motorized zoom lens is issued The Cloud Terrace and camera lens by the RS485 duplex interface of high-definition camera;
High-definition camera is connected with PC by network, by the PC of coding with video image, range data, a The Cloud Terrace angle transmission rear end.
Preestablish following value in the software on the PC: the field angle size of camera lens under each enlargement factor.
The principle of range finding below is described:
Consult shown in Figure 2ly, the distance measuring and calculating principle of beam radar is described.
The ultrasonic velocity of supposing radar is v (m/s), receives mistiming with emission and be t (s) (T2-T1), and then video camera (radar) apart from the distance L (m) of object is:
L＝0.5×v×t
Precision:
Sensor error: this case sensor uses is the precision that 89C51 single-chip microcomputer timer that the 12MHz crystal is made clock reference can easily count down to 1 μ s, so system adopts the 89C51 timer can guarantee that time error is in the measurement range of 1mm.
The ultrasonic propagation velocity error: the temperature of hyperacoustic velocity of propagation air has confidential relation, normal temperature is between 0 ℃-40 ℃, its velocity error that causes is in 25m/s (332m/s-356m/s), and the 100m measuring error is about 7.2m, and the 1m measuring error is about 7.2mm.V=340m/s (20 ℃) when this case is calculated, thus error 1m 2.4mm～-4.5mm, total like this error 1m 3.4mm～-5.5mm between, be acceptable for embodying basic its precision of geography information on the video monitoring.
Consult Fig. 3, the transformation of scale of measuring distance to the video image dimension of object is described.
L is measured by beam radar among the last figure, is assumed to be 100m;
α is the field angle of camera lens in vertical direction, is assumed to be 60 degree;
The account form of object height H so all over the screen is
H＝2×L×tg(0.5α)
On image coordinate, suppose that the horizontal linear distance of 100 pixels is 1, the coordinate dimension of 5,000,000 pixels (2500*2000) is a level 25 so, vertical 20; H=20 when promptly last figure object is all over the screen, w can obtain by intercepting two points on image coordinate, and we can obtain real object width W and are thus:
W＝H×w/h
So in the video tour picture on the software platform of computing machine, can directly provide the distance of any point-to-point transmission in the vertical plane for fixing scenery by the reconnaissance location of mouse.
The camera lens enlargement factor provides another transformation of scale coefficient, therefore selected simultaneously certain zone is that linkage The Cloud Terrace and camera lens further camera lens to make and selects the zone to be full of screen, in new video area, still can survey and draw out size, and the details of distinguishable true scenery.
We regain its lateral dimension by rotary platform for the situation that the inclined-plane occurs, as Fig. 4;
The rotational angle β of The Cloud Terrace is retrievable, and L1, L2 are measured by beam radar, thus the chamfered edge of object can calculate according to trigonometric function, but also be measuring amount.
In sum, on the coordinate of video pictures, can depict the outline line of scenery, draw out the 3 D video simulation map of certain scaling thus or in video image, can calculate size, the distance of object with mouse with mouse.
Thereby also can import interlock The Cloud Terrace, camera lens for known coordinate information and check this zone.
The utility model has solved the deficiency of ordinary video monitoring on the reflection geography information, extended the availability of video image, the real scene that monitors of reduction is applicable to the non-accurate landform measuring method of auxiliary or other broader region of the monitoring at large-scale place such as airport, harbour etc.
