Abstract
The invention discloses a method for designing an image collecting system of a quadcopter. The method includes the steps that an STM32 using an ARM Cortex-M3 as a kernel serves as a main control chip, a CMOS sensor OV7670 is used for collecting images, image data are controlled by the main control chip to be stored into an FIFO storer AL422B, the collected images are displayed on a touch screen through a main controller or are stored into an SD card, a 2.4 G module is used for achieving wireless communication transmission power supply, the surrounding environment information can be collected, and thus control over aircrafts all around is achieved. The method for designing the image collecting system of the quadcopter has the advantages that the image collecting efficiency is high, the size is small, power consumption is low and expandability is high.
Description
Technical field
The invention belongs to vision guided navigation field, relate to a kind of design of four-axle aircraft image capturing system.
Background technology
In recent years, the continuous pursuit that continuous progress and people along with mankind's science and technology live to safety, easily and efficiently high-quality, IMAQ is applied to the fields such as Smart Home, image recognition, environmental monitoring more and more.Four-axle aircraft also more and more receives the concern of people as a kind of representative of unmanned plane, and its navigate mode also occurring to change, combines from inertial navigation and GPS, to the application of vision guided navigation at it.Namely vision guided navigation adopts vision sensor to gather ambient condition information, utilizes image processing techniques, is resolved the geometric position between environmental information and carrier, thus realize the location of carrier.The present invention, namely under the background of four-axle aircraft vision guided navigation, devises its image capturing system.
Summary of the invention
The present invention devises a kind of portable digital image acquisition system based on STM32, its design is: (1) is adopted using the ARM Cortex-M3 STM32 that is kernel as main control chip (2) cmos sensor OV7670 to carry out IMAQ (3) and controls that view data is deposited (4) in FIFO memory AL422B by main control chip and be finally shown on touch-screen by master controller by the image of collection, or is stored into SD card interior (5) and realizes wireless communication transmissions to computer by 2.4G module.
This image capturing system only just achieve with a STM32 chip function of OV7670 is controlled, the function such as timing synchronization, data acquisition and procession, system cost is low, compact conformation, powerful.Simultaneously because the design adopts transducer and the processor chips of Low-voltage Low-power, make the power consumption of whole system very low, can be easy to this system transplantation, in embedded mobile device, there is certain practical value.
Accompanying drawing explanation
Fig. 1 is this image capturing system frame diagram.
Embodiment
The specific design thinking of key link is as follows:
1. the design of image acquisition circuit
The operation principle of image capturing system is as follows: as shown in Figure 1, when gathering image.First light is irradiated on subject, object by light reflection in cmos sensor OV7670, light sensitive diode in QV7670 receives illumination, produces the signal of telecommunication of simulation, first the signal of telecommunication is amplified by the amplifier in this photo-sensitive cell, is then directly changed into corresponding digital signal by A/D converter.Gained digital signal is directly conveyed after merging and hands over inner dsp chip process, controls to import in data buffer AL422B to cushion by STM32F103 according to the view data after the configuration process in register.After camera OV7670 transfers a two field picture to data buffer AL422B, STM32 processor is reads image data from data buffer AL422B, again by image data transmission to computer host computer, also by SD card interface, image can be deposited in SD card simultaneously.
Introduce this image capturing system hardware composition part below.
(1) Core Microcontroller
Embedded microprocessor becomes the optimal selection of portable system with its advantage such as high-performance, low-power consumption.The STM32F103 chip that the design adopts ST company to develop, so its feature is at 32 digit flash memory microcontrollers based on ARM Cortex-M3 kernel.
(2) CMOS camera
CMOS camera selects the OV7670 of Omnivision company.Its feature is its embedded 10 A/D converter, the view data of exportable 8 RGB/YCBCR/YUV forms, with standard SCCB bus interface, and compatible I
2c bus interface.
(3) frame buffer (AL422B)
Select the shared data RAM of Large Copacity AL422B as sampling processing of Avrlogic Technologies company of the U.S..The FIFO storage chip of its feature to be memory capacity be 384K × 8B.
(4) SD card
The design selects the SD storage card storage of collected information of Jin Shidun 4G. and its feature is a kind of based semiconductor flash memory.
(5) LCD liquid crystal display screen and other peripheral hardwares
The design selects 3.2 cun of TFT liquid crystal display screen 320QVT, and its data pin is directly connected with FSMC bus interface.
The functions such as the present invention adopts STM32F103 to achieve to control the function of OV7670, timing synchronization, data acquisition and local storage.In actual application, display effect is good, and image quality loss is little.The IMAQ efficiency of this system is high, volume is little, low in energy consumption, extensibility is strong.View data by wired or wireless Internet Transmission to host computer, can realize the remote collection of image information.
Claims (4)
