Embodiment
Embodiment 1
The invention discloses a kind of laser installation and locating method of fire detector camera, comprise pre-conditioning step and installation steps, wherein:
Pre-conditioning step comprises:
1) configuration is installed model machine and is regulated according to the setting angle of scope to model machine of required monitoring;
As shown in Figure 2, camera model machine 2 configuration is arranged on support bar 1, described support bar 1 is perpendicular to the ground intersects at a G, according to the inclination angle of this camera model machine 2 guarded region adjustment camera model machine 2 that monitor reflects, after adjustment, this guarded region lower left corner is A point, and the lower right corner is B point, lower boundary mid point is E point, and coboundary mid point is F point.So, E point is the best lower limit distance that can enter camera model machine 2 visual field to the distance of G point.G, E, F 3 are positioned at same straight line.Image acquisition region (i.e. guarded region) ABCD, the CD that just can determine to expect to enter camera view by ABEF 4 were the line segment of F point perpendicular to EF, AD and BC is parallel to EF.
2) regulate the laser locator be arranged on described model machine, the laser that laser locator is launched is incident to the border corresponding to this laser locator;
In the present embodiment, the mounting means of laser locator as shown in Figure 1, comprises 4 laser locators, and this laser locator respectively arranges one at the center line at the bottom of camera model machine and top, respectively arranges one at the two ends, bottom of above-mentioned camera model machine.
After regulating the laser locator be arranged on described camera model machine 2, the laser that 4 above-mentioned laser locators are launched is incident to corresponding A, B, E and F tetra-points respectively.
So, in four borders of guarded region, the laser that each border has one group of laser locator to launch incides on this border.In the present embodiment, the laser having three groups of laser locators (often group is 1) to launch incides on lower boundary, the laser having one group of laser locator to launch incides on coboundary, and the laser having one group of laser locator to launch respectively incides on left margin and right margin.It is the first laser locator that the laser sent incides the leftmost laser locator of described lower boundary, and it is the second laser locator that the laser sent incides the rightmost laser locator of described lower boundary; The laser that described first laser locator is launched is incident to the point of interface of described left margin and described lower boundary; The laser that described second laser locator is launched is incident to the point of interface of described right margin and described lower boundary.
3) recording step 2) in the configuration parameter of laser locator and installation site and angle;
To the camera of same model, the size of viewing area (i.e. guarded region) ABCD expected is fixing, therefore, all the other cameras (camera except except camera model machine) are installed if time first draw distance support column 1 regular length and perpendicular to the line segment AB of GE, allow corresponding laser locator incide ABE tri-point, the desired region observed of camera can be determined.
Installation steps comprise:
4) laser locator to be arranged on camera to be installed and described laser locator is regulated, the mounting means of described laser locator is identical with the mode of laser locator on described model machine, and the adjustment criteria of described laser locator is with reference to the configuration parameter of the laser locator recorded in step 3) and installation site and angle;
5) camera to be installed is installed in configuration, starts the laser locator on this camera, regulates according to the setting angle of guarded region border to this camera that the shoot laser of this laser locator is determined;
The laser penetrated according to corresponding laser locator determines the position of ABEF tetra-points, and then determine guarded region ABCD by ABEF 4, then according to ABEF 4 positions, the setting angle of this camera (comprise luffing angle and the anglec of rotation is carried out) is regulated, make the position that guarded region ABCD reaches suitable.
6) installation steps 4 are repeated) and 5), complete the installation positioning test of residue camera.
So, in above-mentioned installation position fixing process, existing installation method conveniently is only needed to carry out once mounting, complete laser locator installation parameter is obtained by pre-conditioning step, then can only need a people just can realize installing for the independence of same model camera according to this installation parameter, only need be incident on ground hot spot according to laser locator during debugging and can determine guarded region, without the need to coordinating between many people, reduce debugging number of times, accelerate installation rate.
Meanwhile, in order to avoid the existence of blind area, in step 5), record the guarded region border of the camera regulated, repeat installation steps when regulating adjacent with this camera camera, the guarded region border of two cameras is connected.In the present embodiment, when regulating second camera adjacent with first camera, the A point hot spot that only laser locator on second camera need be made to determine overlaps with the B point hot spot that the laser locator on first camera is determined or B point hot spot that the laser locator on second camera is determined overlaps with the A point hot spot that the laser locator on first camera is determined.This operating process only needs installation personnel to visually observe the position of hot spot on ground, regulates rapidly, accurately, effectively avoids monitoring blind area.
Embodiment 2
In embodiment 1, often organize laser locator to only have 1 (namely each for determining that the laser locator of same hot spot only has one), when the light that cam lens is incided on the laser that laser locator is launched and guarded region border is not parallel, the monitoring range determined according to ground hot spot and actual guarded region may differences to some extent, for avoiding this undesirable condition, the number often organizing laser locator is decided to be at least 2 and (in the present embodiment, is two, concrete mounting means is see Fig. 3), in use, often organize the function that laser locator completes single laser locator in above-described embodiment 1, with the borderline same point of laser locator determination guarded region of group.The method of the present embodiment is substantially identical with embodiment 1, and its difference is, in pre-conditioning step, the hot spot with the laser locator of group is overlapped, the boundary position of the hot spot determination guarded region after coincidence; In installation steps, regulate camera to make to overlap with the hot spot of the laser locator of group in step 5), utilize the hot spot overlapped to determine ABEF tetra-point, thus determine guarded region.
So, determine guarded region by the hot spot after overlapping, laser and the not parallel scope caused of camera incident ray can be avoided to determine inaccurate problem, further avoid the generation of monitoring blind area.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
