Description
Technical field
The utility model relates to ranging technology field, particularly a kind of seizure object based on single camera and range measurement system.
Background technology
Target distance measurement is the important component part of the robot such as football, basketball, is to ensure that robot can arrive appointed place, completes the important prerequisite of required movement.The devices such as laser range sensor, ultrasonic sensor, infrared distance sensor, photoelectric sensor, grating sensor are mainly applied in range observation.Wherein be applicable to having ultrasound wave, laser sensor at a distance.
But ultrasonic sensor is used for avoiding obstacles in robot, be rarely used in the measurement of distance.Its reason has: 1. reflection problems.What cause this problem is because sound wave reflection, when detecting object, if the position of object is appropriate, so feed back distance error little, if but testee is not in appropriate angle, or object is in mobile status, so the distance of actual detection may not be actual range.2. noise problem.The frequency of operation of most ultrasonic sensor is at 40-50HZ, but often the sound frequency of its workplace is all larger, has influence on the correctness of range observation.3. cross jamming problem.When a robot adopts multiple ultrasonic sensor to measure, the situation that signal that multiple sensor sends interferes with each other inevitably can be produced.4. need to provide power supply and be complicated peripheral circuit, cost is higher.
The measuring method of laser range sensor generally adopts impulse method.Not only the laser that stadimeter sends receives after the reflection of object being measured but also by stadimeter, and stadimeter can two-way time of recording laser.The degree of accuracy of laser ranging is high, but equipment price is expensive, and the cost of the device of range finding is directly proportional to the rate respectively of distance measuring equipment, be not suitable for general robot and make, and volume is more very much not adapted at robot platform is laid.In addition, laser range finder is mainly operation material with laser, if laser is irradiated to eyes, skin can bring certain injury.
Summary of the invention
For the problems referred to above, it is simple that the purpose of this utility model is to provide a kind of structure, with low cost, use safety, measures accurately based on seizure object and the range measurement system of single camera.
Realize the technical solution of the utility model as follows:
Based on seizure object and the range measurement system of single camera, comprise host computer, camera module, Labviewvision module, wireless communication module, locking module and direction adjusting module,
Described host computer is connected with camera module, and camera module is used for the position of captured target object;
Labviewvision module is connected with camera module, and Labviewvision module receives the image information from camera module;
Labviewvision module is used for image information and is converted into digital signal and transfers to host computer;
Wireless communication module, locking module and direction adjusting module are connected to host computer;
The camera adjustment unit be connected by signal with direction adjusting module is provided with in camera module, advantage is camera adjustment unit and direction adjusting module mutual induction, by the manipulation camera adjustment unit of the simple and fast of direction adjusting module, thus be convenient to the angular setting of camera module.
Camera adjustment unit comprises the motor that to be connected with camera module, motor is provided with motor driver, advantage is by motor driver drive motor, makes the angular setting that camera carries out up and down under the effect of motor, thus is conducive to the tram that it catches object most.
Wireless communication module comprises WIFI and bluetooth module.
Have employed above-mentioned scheme, whole range finding hardware device of the present invention only has a camera module, camera module mainly adopts CCD camera to gather image, by camera collection image, without the need to external circuits, camera is connected by wireless communication module with host computer, and structure is simple, with low cost.By the image information of Labviewvision resume module camera collection, and the air line distance of object apart from camera is shown in real time on host computer, Labviewvision module have image collection and identify carry out judging, controlling, make operation more accurate, there is confidence level, hommization, intellectuality.Use safety of the present invention, measure accurately, volume is little, is applicable to robot and makes.
During use, manipulated by host computer, adjusted the angle of camera by direction adjusting module, locked by locking module after capturing the correct position of object, prevent it from relocking and occurring deviation.
In most of the cases, testee from camera more away from, object display in the picture will be less.Contrary more closely will be larger.In the present invention, the image information captured can be converted in host computer and show the wide and high pixel quantity of object (i.e. coordinate figure) by Labviewvision module, can calculate the air line distance between object and camera by the actual range calculating the pixel quantity representative in unit length.
