Handle in step (b) The Cloud Terrace 1 servo-actuated time, be first move along Y-axis, then along X-axis movement.
As shown in Figure 1, photoelectric integrated and intelligent aware platform comprises three parts: laser range finder 3, thermal infrared imager and The Cloud Terrace 1.Thermal infrared imager part can solve hidden, block, problem that the condition hypograph such as night and smog gathers; Laser range finder solves the problem to the range determination of the target traced into; Servo-actuated according to the motion control The Cloud Terrace of target, realize the real-time follow-up to target.Thermal infrared imager combines with laser range finder both realize target image acquisition, can measure again the distance of target, obtains the distance of each period in target travel process by the servomechanism real-time follow-up target of The Cloud Terrace simultaneously.Central processing unit 4 can connect a main control module, and main control module can control central processing unit 4 and send instruction.
As shown in Figure 2, distance measuring equipment of the present invention forms primarily of two parts, i.e. image capture module and range cells part.Wherein range cells sets up module, spacing module, servomechanism module, range finder module composition primarily of coordinate.What image capture module adopted is thermal infrared imager based on photoelectric integrated and intelligent aware platform, and it can realize night, smog and a little image information collecting blocked etc. under specific condition.In range cells, the main task that coordinate sets up module sets up coordinate system at thermal infrared imager display interface to go out the coordinate figure of target at display interface with mapping; The main task of spacing module is the distance being obtained target and picture centre also i.e. electro-optical system center by the coordinate figure on display interface; The main task of servo antrol module is that the pitching driftage of using algorithm instruction to control The Cloud Terrace according to distance value makes the center of electro-optical system overlap with target; The main task of range finder module sends the distance that distance measuring instruction measures target.Image capture module and range cells constitute range measurement system jointly.In addition, in decision package, the main task of data transmission module is that real-time for the measurement result of target recognition and tracking result and distance is passed to main control module; The main task of main control module analyzes the result of data, provides next step action instruction.Target recognition and tracking module main task identifies the target detected according to automatic Target Recognition, uses Moving Target Tracking Algorithm to carry out real-time follow-up to target, for range cells of the present invention is prepared.
As shown in Figure 3, flow process of finding range in the present invention is as follows: after the selected target of target recognition and tracking module, and range measurement system starts, and makes the area of target in picture keep certain proportion by Zoom control.As shown in Figure 4, set up coordinate system XOY at display interface, true origin O (0,0) is the center of electro-optical system, and the coordinate of hypothetical target in interface coordinate system is A (x
0, y
0), according to the distance at the center of target's center and electro-optical system, determine the direction that The Cloud Terrace moves and amplitude.The Cloud Terrace is controlled servo-actuated by the instruction of serial ports transmission algorithm, because target is motion, so need in this process constantly to upgrade the positional information of target, by the distance at constantly revise goal and electro-optical system center, realize the parameter adjusting The Cloud Terrace servo antrol in real time.After the center of electro-optical system overlaps with target, namely control system is according to the instruction of the communications protocol transmission measuring distance of laser range finder later in the center run-home of electro-optical system, and the value returned is the distance value of target.Finally, the distance value of target will be reached main control module, wait for assigning of the order of next step action.
As shown in Figure 5, the point that true origin is the place, center of electro-optical system is fastened in initial coordinate, in target travel process, constantly upgrade the coordinate system of display interface, and the coordinate figure of target and the coordinate figure of electro-optical system central point are upgraded, revised, finally reach electro-optical system center to overlap completely with target, realize range finding; After target is found range, proceed the renewal correction of coordinate, now, target (target's center overlaps with picture centre) becomes true origin, the position of subsequent time target is determined and to control The Cloud Terrace servo-actuated, range finding once on carrying out after the center of electro-optical system overlaps again with target under new coordinate system X ' O ' Y '.In target travel process, whole process that is servo-actuated, that aim at constantly is carried out upgrading and revises, and makes the range finding of target more accurate.
As shown in Figure 6, if do not have The Cloud Terrace servomechanism for system in figure, under the state that image capturing system is static, target is at the possible track of display interface.Fig. 7 is in target travel process, and by constantly upgrading coordinate system, The Cloud Terrace servomechanism constantly adjusts the process that orientation and amplitude experience, and can find out, in target from A
0to A
3process in, the distance of electro-optical system central shaft (i.e. true origin) and target is more and more close, until overlap.
The judgement that the center of electro-optical system overlaps with target: for pedestrian, the center (i.e. picture centre) of electro-optical system overlaps with the upper position (i.e. the above position of waist) of people can (center of electro-optical system and human body waist above position spacing be less than the threshold value Δ r of setting); For vehicle, laser pulse signal can be made to be difficult to be reflected back toward reception mirror because vehicle body exists inclined-plane, thus causing the failure of finding range, overlap with the vehicle lower middle portion at the center and vehicle that refer to electro-optical system of the center of the electro-optical system therefore in the present invention overlaps (the threshold value Δ r that the center of electro-optical system and vehicle lower middle portion spacing are less than setting).
