Embodiment
It is understandable to enable above-mentioned purpose of the present utility model, feature and advantage to become apparent, below in conjunction with the accompanying drawings to this
The specific embodiment of utility model is described in detail.
Indoor Robot determines its position and navigation by collection and identification road sign image.
Referring to Fig. 1, a kind of supplementary lighting sources control system of image identification system, including triggering input module, CPU module,
Supplementary lighting sources module and camera control module.
Wherein, the triggering input module receives image capture instruction, and the instruction is sent to CPU module.
Referring to Fig. 3, the triggering input module include the first optocoupler, image capture instruction by the first optocoupler send to
CPU module.
Specifically, when the triggering input module receives image capture instruction, first optocoupler sends optical signal
Be converted to current signal and be output to the CPU module again, so, when site environment is more severe, there is larger noise interference,
Input optocoupler makees interface, and signal and noise can be isolated, and reduces other signals by mistake as image capture instruction
Probability.
In the present embodiment, R1 uses 1k ohm of resistance, and R2 can be using 47K ohm of resistance, and VCC is 5V, also, two
Place's ground path is not connected.
In circuit diagram shown in Fig. 3, in ends representative image acquisition instructions input, out ends intervention CPU module, by image
Acquisition instructions are sent to CPU module.
The CPU module is connected with triggering input module, and the image that CPU module is used to receive triggering input module transmission is adopted
Collection instruction, and control supplementary lighting sources module and camera control module.
Referring to Fig. 1, in the present embodiment, the system also includes power supply, and the power supply is connected with CPU module, is described
System power supply.
Supplementary lighting sources module is connected with CPU module, and light filling is carried out under the control of CPU module；Camera control module and CPU
Module is connected, and IMAQ is carried out under the control of CPU module.
Specifically, when the road sign image that robot needs to gather in its residing space environment is used to determine its position, institute
The triggering input module that stating robot can send in image capture instruction, the utility model system receives image capture instruction,
And logical to send the instruction to CPU module, CPU module just controls supplementary lighting sources module to carry out supplementary lighting sources unlatching, then controls
Camera control module is acquired image, after the completion of collection image, and CPU module controls the supplementary lighting sources module to close light filling
Light source.
Referring to Fig. 2, T1 represents that the supplementary lighting sources open duration, when T2 represents the camera control module collection image
Long, 1 point represents the supplementary lighting sources start-up time, and 1 ' point represents the supplementary lighting sources close moment；2 points represent that the camera is opened
Begin collection image shutter opening, and 2 ' points represent that the camera collection image completes shutter close.
The CPU module control supplementary lighting sources module is opened supplementary lighting sources before camera control module collection image and mended
Light, that is, 1 point moment is earlier than the 2 point moment.
Because, if CPU module control camera control module first gathers image, and control supplementary lighting sources module
After carry out light filling, then, the image that the camera control module is very likely collected unintelligible, matter due to light
Amount is not high so that robot can not pass through its position of the image recognition and navigation.
Referring to Fig. 2, the CPU module control supplementary lighting sources module closes light filling light after camera control module collection image
Source, 1 ': moment is later than at 2 ': moment.
Because, if CPU module control supplementary lighting sources module first closes supplementary lighting sources, then also in control phase
Machine control module continuous collecting image, then, after supplementary lighting sources are closed, what the camera control module was very likely collected
Image is unintelligible due to light, of low quality so that robot can not pass through its position of the image recognition and navigation.
Generally speaking, during the CPU module control camera control module gathers an image, the CPU module
The supplementary lighting sources module must be controlled to open supplementary lighting sources before camera shutter starts to shoot, i.e., when 1 point moment is earlier than 2
Carve, turning off supplementary lighting sources 1 ' the point moment after camera shutter terminates is later than at 2 ': moment, the supplementary lighting sources opening time and also
It is longer than the camera shutter shooting time, that is, T1 ＞ T2；In fact it is, when the CPU module controls the camera control
When molding block gathers image, the supplementary lighting sources module must be opening in light filling, as long as the CPU module controls institute
When stating camera control module and not gathering image, the supplementary lighting sources module should be just closed mode, energy-saving consumption-reducing.
In the present embodiment, the supplementary lighting sources module light source opens duration more than 1 microsecond, less than 1000 microseconds；Camera
Control module collection image duration is delicate less than 100, and in fact it is, T1 is delicate more than 1, less than 1000 microseconds, T2 is less than 100
Microsecond.
In other embodiments, because camera configuration difference may cause the Polaroid aperture time of camera different, therefore,
The supplementary lighting sources module supplementary lighting sources open duration and camera control module and gather image shutter duration according to camera configuration not
There can be different durations simultaneously.
With reference to Fig. 4, the supplementary lighting sources module includes the second optocoupler, and CPU module controls supplementary lighting sources by the second optocoupler
Module.
Specifically, when the CPU module receives the collection image command of the triggering input module transmission, described the
Two optocouplers send optical signal and are converted to current signal, so, the drive signal that the supplementary lighting sources module is turned on and off, and
The collection signal of camera control module collection image is controlled with high speed photo coupling isolation and amplifier, can be effectively by signal and miscellaneous
News are isolated.
In the present embodiment, the output end makees switch output using metal-oxide-semiconductor, can ensure output current, the CPU moulds
Block output high level pulse controls the camera control module to start to gather image.
In other embodiments, the output end can make switch output, such as other triode switches using other articles.
In the present embodiment, R3, R4 use 1K ohm of resistance, and R5 uses 10K ohm of resistance；Ground path at three
It is not same ground path, but is grounded respectively.
In the present embodiment, the supplementary lighting sources of the supplementary lighting sources module are LED.
In other embodiments, it is also possible as light source using other kinds of lamp.
Prior art is compared, and the technical solution of the utility model has advantages below：
The supplementary lighting sources control system of image identification system of the present utility model can be according to need to actually control the switch of light source
Situation, when needing collection image, control supplementary lighting sources, which are opened, is easy to collection clearly image, need not gather image time control
Supplementary lighting sources processed close energy-saving consumption-reducing, very environmentally friendly, and can collect high-quality image when gathering image.
Although the utility model is disclosed as above, the utility model is not limited to this.Any those skilled in the art,
Do not depart from spirit and scope of the present utility model, can make various changes or modifications, therefore protection domain of the present utility model
It should be defined by claim limited range.
