Passive optical motion capture equipment of the present invention can complete the accurate seizure to object motion under high-speed motion, is suitable as the infrastructure device in high-speed moving object motion capture system.
The present invention is based on described passive optical motion capture equipment, propose a kind of passive optical motion capture system further, it is made up of multiple described passive optical motion capture equipment, POE switch and host computer substantially; Multiple described passive optical motion capture equipment utilizes described Ethernet interface to be connected with POE switch by a netting twine respectively, and POE switch connects with main control computer.
To in the motion capture process of moving object, the Ethernet interface of himself is utilized to be connected with same POE switch by a netting twine respectively at least two passive optical motion capture equipment of the present invention, and then this POE switch is connected with a main control computer, form a set of motion capture system thus.At least two passive optical motion capture equipment in this system are placed in moving object surrounding diverse location to be captured, optical lens is alignment motion object simultaneously, master slave relation between at least two passive optical motion capture equipment can be set arbitrarily, also can not master slave relation be set.Start to enter motion state after the surface of moving object key position be captured fixes Marker, the light source of every platform passive optical motion capture equipment sends Infrared irradiation moving object, the Marker reflects infrared light of surface of moving object gets back to the optical lens of capture device, optical lens according to the control taking moving picture of imaging electronics board, by the FPGA module process being transferred to master board after the imageing sensor acquisition of image data in imaging electronics board by FMC interface.In described capture-process, POE switch powers and transmits data and synchronizing signal to every platform capture device by a netting twine, and every platform capture device also transmits data and synchronizing signal by same netting twine to POE switch simultaneously.Main control computer can receive the data of each capture device and the master slave relation arranged between capture device by POE.
In said process, all devices of capture system has all needed the work of power supply, transfer of data, synchronous three types.Each capture device existing needs the cable of three or more just can complete the work of this three types.The present invention achieves the simplification of structure and operation by the architecture advances of following two aspects: one is that imaging electronics board and master board are adopted FMC interface compact siro spinning technology, thus focuses on unified for the data-signal of collection to master board; Two is after being transformed by master board circuit, combines, arranges Ethernet interface in master board, complete the mutual biography with the electric power in the external world, data and synchronizing signal by means of only a netting twine by consistent with data-signal for synchronizing signal.In equipment of the present invention, data-signal and electric power (external power is powered), enter the filter in master board via Ethernet interface, data-signal is separated with electric power by filter; Electric power, after rectification main circuit and transformer process, reaches the use standard of each components and parts, for each components and parts; Data-signal, via ethernet transceiver, enters operation and process (this is DRP data reception process, and the process of transmitting of data is its inverse process) that FPGA carries out data; Synchronizing signal is a kind of special data-signal, together transmit at ordinary times, but synchronizing signal has limit priority with normal data signals, and after receiving synchronizing signal, FPGA triggered interrupts, performs synchronous task immediately.Capture device through above-mentioned transformation not only increases data accuracy, and effectively improves the latency issue of legacy identification system.Especially it is worth mentioning that, capture device of the present invention only can just complete power supply, transfer of data and synchronous three work with a straight through cable after transformation, while ensureing that data integrity transmits reliably, external number of cables is dropped to minimum.This is undoubtedly for the actual use of capture device brings great convenience.Existing most equipment, due to cable Numerous, often brings complex structure entanglement, and use difficulty to strengthen, failure rate rises, the many disadvantages of maintenance cost height etc., for motion capture practice causes very large puzzlement.The present invention solves the technical problem of this long-standing problem people by the ingenious mode being not easy to expect, and obtains good technique effect, and the good use sense that the practical application for motion capture equipment is brought is subject to, and uses difficulty and failure rate significantly to reduce.
In addition, the main power consumption of motion capture equipment is consumed by radiation source assembly, existing capture device is all lay a large amount of LED lamp bead as radiation source around optical lens substantially, and in capture-process, LED can send continual Continuous irradiation to moving object.Which realizes simple, but equipment power dissipation is large, and service life of equipment is low.In capture device of the present invention, master board be provided with FPGA module and with level transferring chip and the control signal output equipment of being with the current drives chip of Enable Pin to form, FPGA exports control signal, the current drives chip enable end of lamp plate is outputted to via level transferring chip, realize the open and close controlling accurately to control circuit for light source plate circuit, make LED only between imaging electronics board exposure period, just perform illumination work.So, the time for exposure each due to imaging electronics board minimum (0.1 ms), therefore LED can save a large amount of invalid illuminations.Based on the operating frequency of imaging electronics board 100Hz and the time for exposure of 0.1ms, LED adopts synchronous flashing type of lighting, and before can being by the lower power consumption of radiation source part 1%.Package is overall, and the power consumption of capture device of the present invention is about 10% of legacy equipment power consumption.
Moreover the image processing speed of capture device of the present invention is compared existing equipment and is obtained significant lifting.In prior art, the view data that capture device captures needs first to transfer to computer reprocessing, and by the restriction of image transmitting and computer disposal performance, general device processing speed is about 60Hz.The present invention attempts in control cabinet, make imaging electronics board be connected by FMC interface with master board, video information imaging electronics board collected receives and sends to master board via FMC interface direct, and FPGA module is adopted in master board, in real time the signal that imaging electronics board is transmitted can be carried out extracting, process and compressing by suitable software program, and then outwards transmit.Because data do not need to pass computer disposal back, and adopt FPGA treatment technology to raise speed, image processing speed can reach 1000 frames/second, is the decades of times of legacy equipment processing speed.
The present invention also provides the application in the fields such as described passive optical motion capture equipment is bionical at sports techniques analysis, experimental center, physiotherapy and rehabilitation engineering, broadcasting and TV cartoon making, virtual reality exploitation, ergonomic, machinery, industrial robot.
