Embodiment
Below with reference to drawings and Examples the utility model is described further.
As shown in Figure 1, be indoor scene footprint imaging device structural representation in the utility model.Indoor scene footprint imaging device is made of system chassis 1, display unit 2, image-generating unit 3, indexing unit 4, control module 5 and lighting unit 6.System chassis 1 comprises upper and lower cabinet, and the two is nested structure, and upper case can be nested in the lower case; Display unit 2 is panel computer, is arranged on the panel computer mount pad at upper case top, is provided with protective cover on panel computer one side, for the protection of panel computer; Image-generating unit 3 is camera, is fixed on the inner tip of upper case; Indexing unit 4 is laser indicator lamp, is fixed on upper case inner by the centre position, and evenly branch is in the both sides of image-generating unit 3; Lighting unit 6 is 2 groups of high-power red-light LED bulbs, is arranged on the lower case two bottom sides; Control module 5 is arranged on upper case inside, a side of image-generating unit, and image-generating unit 3, indexing unit 4, lighting unit 6 are electrically connected with display unit 2 by control module 5 respectively.
As shown in Figure 2, be indoor scene footprint imaging device A-A diagrammatic cross-section in the utility model.Wherein, image-generating unit 3 comprises camera chip 301, camera lens switching circle 302, camera lens 303 and cover plate 304.
The utility model according to the footprint shape long and narrow (the footprint size width usually at 120mm between the 160mm, length at 300mm between the 400mm) characteristics, use 4 cameras to consist of core image-generating unit 3, allow them along footprint length direction spaced sequence, each camera only is responsible for the imaging in footprint 1/4th zones, forms complete footprint image by four width of cloth Image Mosaics at last.Guaranteeing under the rational imaging resolution (greater than 300 point/inches) like this, again can be because of the too large distortion in visual field.
The key of illuminator 6 at first is to guarantee enough little glancing incidence angle.The illumination component that the utility model uses is the high-power red-light LED bulb that front end adds collimation lens, 6 ~ 8 lamps of one row, consist of a lamp group that flat illuminating bundle is provided, its width can the ensuring coverage footprint whole width, its length can ensuring coverage half above footprint zone, and obtained enough little grazing angle in this zone.Two lamp groups are symmetrically placed in respectively the two bottom sides of system chassis, separately the sole of corresponding responsible footprint and the illumination of heel part.If only use a lighting lamp group, then in order to obtain covering the uniform glancing incidence illumination light of whole footprint length, also need light source is moved to further from the position in footprint zone, like this just be difficult to light source is integrated into system.
During system works system chassis 1 place the footprint zone directly over, system chassis 1 has covered most of surround lighting for the interference illumination of footprint, cooperate the use of red monochromatic source, so that image-forming condition is greatly improved than classic method, signal noise ratio (snr) of image obtains effectively to promote.
System chassis 1 is designed to up and down nested structure for satisfying portable requirement.Superstructure is integrated display unit 2, image-generating unit 3, indexing unit 4 and control module 5, lower floor's tank ends is integrated lighting unit 6.Superstructure is extracted out and be may be superimposed on the understructure during work, reaches suitable imaging height; When not working, but the superstructure depression in lower layer box body so that system carry half that volume only has about duty volume.
Complete footprint zone be a length breadth ratio surpass 2 to 1 rectangle (the footprint size width usually at 120mm between the 160mm, length at 300mm between the 400mm).Therefore consider this zone is divided into 4 imaging subregions, have the overlapping region of 10-20 mm wide between the adjacent sectors, sectional image of picked-up is responsible in use side by side 4 cameras separately.4 camera orientation, spacing reality can be not in full accord, and the focusing amount of its camera lens also has minute differences, so the image of their picked-ups need to be adjusted to the image with identical orientation and multiplying power by discernible unique point, so just can carry out the splicing of back.Discernible unique point is finished by indexing unit 4, and indexing unit 4 comprises 3 groups of laser, every group of 2 laser spots, in a distance.Every group of luminous point is incident upon respectively in two overlay regions between the subregion, therefore has 3 overlay regions between 4 subregions, so need 3 group mark luminous points.Same group mark point meeting imaging in adjacent two width of cloth block plans, their dot spacing and position angle be meeting different (because of the image-forming condition difference of two cameras) in this two width of cloth figure, allow them agree and just need to adjust at least wherein convergent-divergent multiplying power and the anglec of rotation of a width of cloth figure, the image of every group mark luminous point all needs so to adjust.Here it is adjusts the image calibration parameter automatically.So just can work out the Digital Image Processing algorithm software and seamlessly they are spliced into a complete footprint figure.
The distance on camera and ground is fixed, thus the enlargement ratio of image also fix, can be with the software accurate engineer's scale of a circle that superposes around the complete footprint figure, and need not when gathering image, to place scale in kind or other objects of reference.
The course of work of system is as follows:
Step 1: send instruction by panel computer to control module 5, light laser indicator lamp, to four footprint subregion projection mark luminous points, control respectively 4 camera collection images by control module 5 again, and then instruction control unit is closed laser indicator lamp;
Step 2: panel computer is analyzed the mark luminous point in 4 width of cloth images, calculates the correction parameters such as convergent-divergent, rotation and translational movement that each figure should adjust;
Step 3: panel computer instruction control unit 5 is lighted the lighting lamp group of footprint one end, and then instruction closes lighting lamp group away from two camera collection half range footprint images of this lamp group; Control the lighting lamp group of the footprint other end, then instruction closes lighting lamp group away from the other half range footprint image of two camera collections of this lamp group again; With the whole footprint that obtains totally 4 width of cloth footprint image block plans be sent to panel computer;
Step 4: the correction parameter that utilizes step 2 to obtain is proofreaied and correct 4 width of cloth footprint image block plans, and 4 block plans after obtaining to proofread and correct also splice, and namely get full width footprint figure.
