Specific embodiment
It is understandable to enable the above objects, features and advantages of the present invention to become apparent from, below in conjunction with the accompanying drawings to the present invention
Specific embodiment be described in detail.
Indoor Robot is by collection and identification road sign image, and then determines its position and navigation.
Referring to Fig. 1, a kind of supplementary lighting sources control system of image identification system, including trigger input module, CPU module,
Supplementary lighting sources module and camera control module.
Wherein, the trigger input module receives image capture instruction, and the instruction is sent to CPU module.
Referring to Fig. 3, the trigger input module includes the first optocoupler, image capture instruction by the first optocoupler send to
CPU module.
Specifically, when the trigger input module receives image capture instruction, first optocoupler sends optical signal
Be converted to current signal and export the CPU module again, so, when site environment is more severe, when 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, resistance of the R1 using 1k ohms, R2 can adopt the resistance of 47K ohms, 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 trigger input module, and CPU module is used to receive the image of trigger input module transmission and adopts
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 connects, and IMAQ is carried out under the control of CPU module.
Specifically, when robot needs the road sign image gathered in space environment residing for which to be used to determine its position, institute
State robot and can send image capture instruction, the trigger input module in present system receives image capture instruction, and
Logical the instruction to be sent to CPU module, CPU module just controls supplementary lighting sources module and carries out supplementary lighting sources unlatching, then controls camera
Control module is acquired image, and after the completion of collection image, CPU module controls the supplementary lighting sources module and closes 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 collected by camera image completes shutter close.
The CPU module control supplementary lighting sources module before camera control module collection image is opened supplementary lighting sources and is mended
Light, that is, 1 point of moment is earlier than 2 points of moment.
This is 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 is unintelligible due to due to light, matter
Amount is not high so that robot cannot 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 are later than at 2 ': moment.
This is 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 due to light, of low quality so that robot cannot 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
When must control the supplementary lighting sources module point moment of supplementary lighting sources, i.e., 1 is opened before camera shutter starts to shoot earlier than 2 points
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
Molding block collection image when, the supplementary lighting sources module must be opening in light filling, as long as the CPU module control 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, as camera configuration difference may cause the Polaroid aperture time of camera different, therefore,
The supplementary lighting sources module supplementary lighting sources are opened 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 trigger 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 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 and starts 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 are using the resistance of 1K ohms, resistance of the R5 using 10K ohms；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 technical scheme has advantages below：
The present invention image identification system supplementary lighting sources control system can according to the switch conditions that need to actually control light source,
When needing to gather image, control supplementary lighting sources are opened and are easy to collection clearly image, control light filling when gathering image
Light source closes energy-saving consumption-reducing, very environmentally friendly, and can collect high-quality image when image is gathered.
Although present disclosure is as above, the present invention is not limited to this.Any those skilled in the art, without departing from this
In the spirit and scope of invention, can make various changes or modifications, therefore protection scope of the present invention should be with claim institute
The scope of restriction is defined.
