Abstract
The utility model relates to a synchronous photography controller for the photogrammetry of non-measurement cameras. The inputs are connected with the standard RS-232C serial interfaces of a computer; the outputs are connected with the electronic shutter releases of a plurality of parallel non-measurement cameras. After the synchronous photography controller receives the photography control signal of the computer, a relay controls the non-measurement cameras to synchronously shoot. During the photogrammetry, the computer controls the non-measurement cameras to synchronously shoot dynamic measuring targets.
Description
The utility model relates to a kind of photogrammetric synchronous photograph control device that is used for.Specifically, be the control signal sent of a kind of receiving computer and control many non-metric cameras and carry out the control device of synchronous shooting measuring target.
Non-metric camera is meant 135,120 or digital camera of charged sub-shutter.Photogrammetric technology requires will photograph to measuring target two above different angles at least.For static object, can use a camera from different perspectives target to be photographed successively.But for dynamic object, must before shooting, be placed in design attitude to two above cameras, simultaneously dynamic object be photographed then.
The purpose of this utility model is exactly to realize the synchronous shooting of two above cameras to dynamic object.
At present dynamic object is carried out synchronous shooting, generally adopt the manual mode of operation of synchronization flash or electronic shutter line in parallel; Use the time interval between the stopwatch records photographing.This mode automaticity is low, accuracy of timekeeping is poor.
The utility model overcomes the limitation of above-mentioned prior art, provides a synchronous photograph control device that is connected between computing machine and the Duo Tai camera.Wherein, adopt standard RS-232 C serial line interface cable to be connected between computing machine and the synchronous photograph control device input end; Be connected with synchronous photograph control device output terminal behind the electronic shutter line parallel of many cameras.The control signal that synchronous photograph control device receiving computer sends is also controlled many cameras and is carried out synchronous shooting, has manual control function simultaneously, replaces the manually-operated electronic shutter control mode of prior art.Under computer program is controlled, carry out synchronous shooting, write down each time of taking, timing and accuracy of timekeeping height automatically by computing machine.
Principle of work of the present utility model: the electronic shutter port of camera has two connecting lines, and using the photography of electronic shutter line in fact is exactly these two connecting lines of short circuit.The utility model is exactly a principle in view of the above, utilizes the adhesive of relay to come two connecting lines of short circuit electronic shutter to realize.Be connected with the output port of synchronous photograph control device behind the electronic shutter line parallel of many cameras, reach the purpose of many camera synchronization photographies of control.
The utility model is made up of shell, power switch, power light, exposure pilot lamp, charging indicator light, manual control button, RS-232 C serial input terminal mouth, two identical synchronous photograph control output port, charging port, printed circuit board (PCB) and accumulators.
Accompanying drawing is the circuit diagram of the utility model example.
Introduce the circuit theory and the working condition of the utility model example in detail below in conjunction with accompanying drawing:
In the accompanying drawing, resistance R 1, optocoupler PC form the input signal optically coupled isolation circuit; Resistance R 2, resistance R 3, optocoupler PC, triode Q, diode D1, relay J 1 are formed driving and control circuit; Resistance R 4, LED 1, J1-2 form the duty indicating circuit; J1-1 is the synchronous photograph control output circuit.
Turn on the power switch K2, power light LED2 is luminous, and the synchronous photograph control device is in holding state.
When input port AB had RS-232 C serial port input signal, the optocoupler PC of optically coupled isolation circuit was in conducting state, and the base stage of the triode Q of Drive and Control Circuit is changed to low spot and puts down, and relay J 1 gets electric and adhesive, and promptly J1-1, J1-2 connect.J1-1 connects and makes synchronous photograph control output circuit output short circuit signal, by electronic shutter line traffic control camera exposure; J1-2 connects and makes the exposure pilot lamp LED1 of duty indicating circuit luminous, indication exposure duty.
K switch 1 is manually to control and testing button.When need were manually controlled and tested local state, elder generation's disconnection synchronous photograph control device was connected with computing machine, presses K switch 1, and optocoupler PC begins conducting, and subsequent process is the same.
When power supply E voltage step-down, charging indicator light LED3 deepening, expression needs charging.9 volts of charging voltages of charging port CD are given power supply E charging by diode D2, resistance R 7, resistance R 6, charging indicator light LED3, power switch K2, fuse F, and charging indicator light LED3 is bright simultaneously, the indication charged state.After electricity was full of, the pressure drop on the resistance R 7 trended towards zero, charging indicator light LED3 extinguishes, and the indication electricity is full of.The effect of unidirectional control diode D2 is: prevent that power supply E from discharging to charging end CD by fuse F, power switch K2, resistance R 6, resistance R 7.
The element of the utility model example figure is selected: optocoupler PC:4N25; Triode Q:2SC8550; Relay J 1:4099; Fuse F:1A; Power supply E:6 musculus rectus femoris maintenance free cell; Diode D1, D2:1N4001; Pilot lamp LED1～LED3: 5 high brightness LEDs; Resistance R 1:1.2K Ω; Resistance R 2:4.7K Ω; Resistance R 3:33K Ω; Resistance R 4:150 Ω.; Resistance R 5:150 Ω; Resistance R 6:5.6 Ω/2W; Resistance R 7:10 Ω/2W.
The utility model is realized the synchronous photograph control to many non-metric cameras, simple in structure, stable performance under computer control.In actual applications, can work out RS-232 C serial communication program and control, not only can realize time-lapse photography control, but but also the time interval between the records photographing improved the timing accuracy and the automaticity of dynamic synchronization photography greatly.
