Description
Technical field
This patent relates to a kind of self-balancing image collecting device based on ultrasonic sensor range finding in Fructus actinidiae chinensis picking robot, is mainly used in the target image collection of Fructus actinidiae chinensis picking robot under field conditions.
Background technology
China is Fructus actinidiae chinensis big producing country, and the shed frame type production structure that Fructus actinidiae chinensis is unique, determine photographic head and can from bottom to top Fructus actinidiae chinensis be carried out the image taking of fruit.Owing to Fructus actinidiae chinensis height off the ground is different, so photographic head is the most different with the distance of Fructus actinidiae chinensis during shooting, there is deviation in the full-size(d) which results in image that photographic head finally shoots and Fructus actinidiae chinensis, have impact on the picture quality of collection.Complicated additionally, due to field conditions, if it occur that tilt may result in photographic head and tilt when Fructus actinidiae chinensis picking robot moves in field, also influence whether the picture quality gathered.Therefore, if ultrasonic sensor can be added on the premise of image collecting device autobalance, utilize it to measure the photographic head distance to Fructus actinidiae chinensis, just can obtain image more reliably.
Owing to the image acquisition of Fructus actinidiae chinensis being the first step realizing Fructus actinidiae chinensis is plucked function, thus one accurately image pickup method final identification of Fructus actinidiae chinensis can be allowed to produce a more preferably effect.Traditional Fructus actinidiae chinensis identification device have ignored the accurate shooting problem to Fructus actinidiae chinensis, and result in the advantages such as intellectuality that intelligent robot represented and accuracy can not perfect embody.This patent is then the otherwise address shooting problem of Fructus actinidiae chinensis on the basis of original Fructus actinidiae chinensis identification device, the i.e. lower section at photographic head adds an acceleration transducer, solve the equilibrium problem of image collecting device, four ultrasonic sensors are installed for obtaining the distance of photographic head distance objective Fructus actinidiae chinensis in photographic head side (top of The Cloud Terrace), are calculated the full-size(d) of Fructus actinidiae chinensis for the later stage by the method for image procossing.Then whole image collecting device is controlled by single-chip minimum system, instructs the precise manipulation of picking robot.This patent uses cradle head of two degrees of freedom, can regulate horizontal and vertical position, is mounted thereon by photographic head, it is achieved photographic head is automatically adjusted to the function of horizontal level.Acceleration transducer is a kind of electronic equipment that can measure acceleration, the acceleration caused due to gravity by measurement, can calculate equipment angle of inclination with respect to the horizontal plane, by analyzing dynamic acceleration, in the way of can moving to analyze equipment.Under using acceleration transducer to ensure that photographic head is at an arbitrary position, it is possible to be automatically adjusted to level, bottom-up shooting Fructus actinidiae chinensis.Ultrasonic sensor is the sensor utilizing the characteristic of ultrasound wave to develop, and both can launch ultrasound wave, it is also possible to accept ultrasound wave.Four ultrasonic sensors are simultaneously to emission ultrasound wave, it is to avoid the phenomenon that single ultrasound wave can not return.The photographic head distance to top measured by four ultrasonic sensors simultaneously, and taking minimum range is the photographic head distance to Fructus actinidiae chinensis, then by similar triangle theory, utilizes image processing method to estimate the actual size of Fructus actinidiae chinensis.
Summary of the invention
For the acquisition problems of Fructus actinidiae chinensis image, this experiment proposes a kind of high efficiency, intellectuality, high self-balancing image collecting device based on the range finding of super body wave sensor accurately.
Realizing above-mentioned experiment purpose is to be realized by techniques below scheme:
This patent includes photographic head, cradle head of two degrees of freedom, acceleration transducer, ultrasonic sensor, single-chip microcomputer five part.It is characterized in that this device is controlled by single-chip minimum system, at cradle head of two degrees of freedom photographic head installed above and four ultrasonic sensors.Acceleration transducer is installed in the lower section of photographic head, and when the position of photographic head changes, acceleration transducer can be detected immediately upon variable quantity, sends the data collected to single-chip microcomputer.Carrying two steering wheels on The Cloud Terrace, first steering wheel is vertical duction steering wheel, is mounted in The Cloud Terrace upper end, and second steering wheel, for being horizontally diverted steering wheel, is mounted in the lower end of The Cloud Terrace.The directional steering of Single-chip Controlling vertical duction steering wheel, steering wheel drives The Cloud Terrace to rotate in vertical direction by gear engagement, and Single-chip Controlling is horizontally diverted the directional steering of steering wheel simultaneously, and steering wheel drives The Cloud Terrace to turn in the horizontal direction by gear engagement.After photographic head is adjusted to horizontal level, four ultrasonic sensors can outwards launch ultrasound wave simultaneously, it is to avoid single ultrasonic sensor emits ultrasonic acoustic waves into the situation of sky.Being reflected back when ultrasound wave runs into object, the data of collection are transferred to single-chip microcomputer by four ultrasonic sensors, and single-chip microcomputer takes the distance as photographic head to Fructus actinidiae chinensis of the minima in four distances, utilizes image processing method to estimate the actual size of Fructus actinidiae chinensis.
Above-mentioned single-chip microcomputer is used for sending reception and processing signal and data, and controls steering wheel and operate accordingly.
Above-mentioned ultrasonic sensor is used for measuring the photographic head distance to Fructus actinidiae chinensis.
Above-mentioned acceleration transducer is used for measuring the variable angle of acceleration of gravity.
Above-mentioned steering wheel is used for The Cloud Terrace is carried out adjustment both horizontally and vertically.
The advantage of this patent: photographic head keeps level with ground all the time, it is ensured that device stability, it is ensured that photographic head directly shoots facing to the fruit calyx part of Fructus actinidiae chinensis from top to bottom.Ultrasonic sensor can measure the photographic head distance to Fructus actinidiae chinensis, by the full-size(d) of similar triangle theory estimation Fructus actinidiae chinensis, the beneficially precise manipulation of Fructus actinidiae chinensis picking robot.
