Description

Technical Field

[0001] This invention relates to the field of information transmission network technology, and in particular to a markerless motion capture camera networking system and method. Background Technology

[0002] Markerless motion capture systems use multiple high-definition, high-frame-rate cameras to simultaneously acquire target images and then reconstruct 3D motion data using algorithms. They are widely used in film and television production, sports training, human-computer interaction, and other fields.

[0003] In the existing system, each motion capture camera is powered by a separate AC220V power line from the nearest available source, and all camera network cables are scattered and connected to the nearest available server room, with each line having its own separate cabling. In this system structure, the wiring is numerous and messy, and with multiple high-definition cameras transmitting images simultaneously, it is very easy to saturate the port bandwidth and cause image packet loss, making it unsuitable for high-definition, high-frame-rate, markerless motion capture. Summary of the Invention

[0004] This invention provides a markerless motion capture camera networking system and method, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A tagless motion capture camera networking system includes: The centralized power supply unit converts AC power to DC power and provides centralized parallel power supply for N markerless motion capture cameras, where 5≤N≤15; The front-end switch is configured in conjunction with the centralized power supply unit and is connected in parallel with the N unmarked motion capture cameras that receive power from the centralized power supply unit for data transmission. An aggregation switch is connected in parallel with several of the aforementioned front-end switches to aggregate data and transmit it to the workstation. The connection unit includes composite connection cables corresponding to the markerless motion capture cameras. One end of each composite connection cable is connected to the markerless motion capture camera, and the other end is connected to the centralized power supply unit and the front-end switch, so as to simultaneously realize power transmission, image data transmission and synchronous trigger signal transmission. A voltage stabilization and compensation unit is installed for the unmarked motion capture camera whose power supply voltage drop exceeds a preset standard. The input end of the voltage stabilization and compensation unit is connected to the centralized power supply unit through the composite connection cable, and the output end is directly connected to the corresponding unmarked motion capture camera.

[0006] Furthermore, the composite connection cable includes a DC power supply core, a 10 Gigabit data transmission core, a synchronous trigger core, and a metal shielding layer; The metal shielding layer separates the internal space of the cable. The DC power supply core is located on one side of the metal shielding layer, and the 10 Gigabit data transmission core and the synchronous trigger core are located on the other side of the metal shielding layer.

[0007] Furthermore, the rated power of the voltage stabilization compensation unit is 1.2 to 1.5 times the peak power of the corresponding markerless motion capture camera under full load conditions.

[0008] Furthermore, the voltage regulation and compensation unit includes a sampling circuit, a PWM control chip, a high-frequency switching boost circuit, and a multi-stage filtering and voltage regulation circuit; The sampling circuit acquires the input voltage of the composite connection cable in real time to obtain the sampling voltage; The PWM control chip compares the sampled voltage with the pre-stored rated reference voltage and dynamically adjusts the PWM duty cycle to control the high-frequency switching boost circuit to perform voltage compensation. The multi-stage filtering and voltage regulation circuit filters out noise and ripple from the compensated voltage.

[0009] Furthermore, the voltage stabilization compensation unit also includes at least one of an overvoltage protection circuit, an overcurrent protection circuit, an overload protection circuit, or an overheat protection circuit.

[0010] Furthermore, the front-end switch includes a synchronization trigger distribution module, which sends synchronization trigger signals to the corresponding N markerless motion capture cameras via the composite connection cable.

[0011] Methods for networking unmarked motion capture cameras include: Convert AC power to DC power and supply power to N unmarked motion capture cameras in parallel, where 5≤N≤15; The power supply, image data interaction and synchronous trigger signal transmission are completed simultaneously for a single markerless motion capture camera. The data from the N markerless motion capture cameras connected in a centralized parallel power supply are collected, processed, and then transmitted externally. Receive and aggregate several sets of data, and then transmit the aggregated data to the workstation. The unmarked motion capture camera whose power supply voltage drop exceeds the preset standard is identified, and voltage compensation is performed separately on the identified unmarked motion capture camera after drawing power from the centralized power supply side.

[0012] Furthermore, the method for determining whether the voltage drop of the markerless motion capture camera exceeds a preset standard includes: The full-load condition of the unmarked motion capture camera is used as the voltage judgment standard. The full-load condition is when the camera is in the highest frame rate acquisition mode and the matching infrared fill light is turned on at full power. Under full load conditions, when the voltage at the power supply terminal of the unmarked motion capture camera is lower than a set percentage of the rated operating voltage, it is determined that the voltage drop exceeds a preset standard, which is 85%-95%.

[0013] Furthermore, after drawing power from the centralized power supply side, voltage compensation is performed separately for the identified unmarked motion capture cameras, including: The input voltage of the centralized power supply side is collected in real time to obtain the sampling voltage; The sampled voltage is compared with the pre-stored rated reference voltage to determine the voltage compensation amount. The PWM duty cycle is dynamically adjusted according to the voltage error to adaptively adjust the boost compensation amplitude. The voltage after voltage compensation is processed to remove noise and ripple.

[0014] Furthermore, it also includes: A unified synchronization trigger signal is sent to N markerless motion capture cameras that are centrally connected in parallel, so that each of the markerless motion capture cameras can synchronously receive the trigger command and perform synchronous acquisition operations.

[0015] The technical solution of this invention can achieve the following technical effects: This invention integrates power supply, data, and synchronization lines through a network architecture consisting of a centralized power supply unit, a front-end switch, and an aggregation switch, along with composite connection cables. This effectively improves the current messy wiring problem and standardizes the overall wiring layout. By constructing the network, centralized data aggregation and transmission are achieved. The overall transmission bandwidth can be increased by relying on 10 Gigabit Ethernet, thereby effectively overcoming the problems of insufficient bandwidth in the original scattered network, bandwidth saturation when multiple markerless motion capture cameras transmit high-definition images simultaneously, and packet loss. It enables compact uploading of grouped data sets, meeting the needs of continuous transmission of high-definition, high-volume data from markerless motion capture cameras.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] Example 1 like Figure 1 and 2 As shown, the markerless motion capture camera networking system includes: Centralized power supply unit 02 converts AC power to DC power and provides centralized parallel power supply for N markerless motion capture cameras 01, where 5≤N≤15; The front-end switch 03 is matched with the centralized power supply unit 02 and is connected in parallel with the N unmarked motion capture cameras 01 that receive power from the centralized power supply unit 02 for data transmission. The aggregation switch 04 is connected in parallel with several front-end switches 03 to aggregate data and transmit it to workstation 07. The connection unit includes composite connection cables 05 that correspond one-to-one with the markerless motion capture camera 01. One end of each composite connection cable 05 is connected to the markerless motion capture camera 01, and the other end is connected to the centralized power supply unit 02 and the front-end switch 03 respectively, so as to realize power transmission, image data transmission and synchronous trigger signal transmission. The voltage stabilization compensation unit 06 is installed for the unmarked motion capture camera 01 whose power supply voltage drop exceeds the preset standard. The input end of the voltage stabilization compensation unit 06 is connected to the centralized power supply unit 02 through the composite connection cable 05, and the output end is directly connected to the corresponding unmarked motion capture camera 01.

[0020] by Figure 1 Taking the labelless motion capture camera 01 networking system shown as an example, 40 labelless motion capture cameras 01 are deployed, divided into 4 acquisition groups of 10 cameras each. Each group is equipped with a centralized power supply unit 02 with an AC220V to DC48V power supply. It should be noted that this invention needs to be implemented when the number of labelless motion capture cameras 01 is at least 2N.

[0021] In this embodiment, 10 markerless motion capture cameras 01 in each group are connected to a front-end switch 03 via corresponding composite connection cables 05, and 4 front-end switches 03 are connected to an aggregation switch 04 via optical fiber. Both the front-end switches 03 and the aggregation switch 04 are preferably 10 Gigabit switches, which can handle the large volume of image data simultaneously output by multiple high-frame-rate markerless motion capture cameras 01.

[0022] This invention integrates power supply, data, and synchronization lines through a network architecture consisting of a centralized power supply unit 02, a front-end switch 03, and an aggregation switch 04, as well as a composite connection cable 05. This effectively improves the current problem of messy wiring and standardizes the overall wiring layout. By constructing the network, centralized data aggregation and transmission are achieved. The overall transmission bandwidth can be improved by relying on 10 Gigabit Ethernet data transmission, thereby effectively overcoming the problems of insufficient bandwidth in the original scattered network, easy bandwidth saturation when multiple markerless motion capture cameras 01 transmit high-definition images simultaneously, and packet loss. It realizes compact uploading of grouped data and meets the needs of continuous transmission of high-definition markerless motion capture cameras 01 with large data volumes.

[0023] During implementation, with varying wiring distances for each unmarked motion capture camera 01, long-distance transmission results in significant line voltage drops. Furthermore, these unmarked motion capture cameras 01 are often high-frame-rate, high-definition capture devices. Taking their application in a digital track as an example, they require strobe lights, which significantly increase instantaneous power consumption under full-load conditions during events, further exacerbating dynamic voltage drops and causing a substantial decrease in the power supply voltage to the remote camera terminals. Based on the above network architecture of this invention, to address these issues, a voltage stabilization compensation unit 06 is selectively installed for unmarked motion capture cameras 01 whose power supply voltage drop exceeds a preset standard. This mitigates the potential voltage loss risks associated with long-distance wiring without requiring modifications to the entire power supply cabling system.

[0024] As a preferred embodiment of the above, the composite connecting cable 05 includes a DC power supply core, a 10 Gigabit data transmission core, a synchronous trigger core, and a metal shielding layer; the metal shielding layer separates the internal space of the cable, the DC power supply core is disposed on one side of the metal shielding layer, and the 10 Gigabit data transmission core and the synchronous trigger core are disposed on the other side of the metal shielding layer.

[0025] In some embodiments of the present invention, the composite connecting cable 05 specifically adopts an 8-core structure, wherein 2 cores are DC power supply cores, and the wire diameter needs to meet the full-load current of the unmarked motion capture camera 01; 4 cores are 10 Gigabit data transmission cores; and 2 cores are synchronous trigger cores, which differentially transmit synchronous signals to achieve the purpose of anti-interference. As a further preferred embodiment, the metal shielding layer can specifically be an aluminum foil shielding layer to isolate interference between power supply and data signals.

[0026] As a preferred embodiment, the rated power of the voltage regulation and compensation unit 06 is 1.2 to 1.5 times the peak power of the corresponding markless motion capture camera 01 under full-load conditions. By limiting the above ratio, a reasonable power margin can be reserved to cope with the instantaneous power consumption fluctuations of the markless motion capture camera 01, compensate for line voltage drops, and ensure stable power supply for the markless motion capture camera 01 under full-load conditions; in addition, it can avoid the waste of component costs due to excessive power margin.

[0027] As a preferred embodiment of the above, such as Figure 3 As shown, the voltage regulation and compensation unit 06 includes a sampling circuit 061, a PWM control chip 062, a high-frequency switching boost circuit 063, and a multi-stage filtering and voltage regulation circuit 064. The sampling circuit 061 collects the input voltage of the composite connection cable 05 in real time to obtain the sampling voltage; The PWM control chip 062 compares the sampled voltage with the pre-stored rated reference voltage and dynamically adjusts the PWM duty cycle to control the high-frequency switching boost circuit 063 to perform voltage compensation. The multi-stage filtering and voltage regulation circuit 064 filters out noise and ripple from the compensated voltage.

[0028] In this preferred embodiment, the sampling circuit 061, the PWM control chip 062, the high-frequency switching boost circuit 063, and the multi-stage filtering and voltage regulation circuit 064 can all adopt existing structural forms. Specifically, the sampling circuit 061 is composed of general-purpose components such as voltage divider sampling resistors and operational amplifiers, and can adopt a standardized sampling circuit. The PWM control chip 062 can adopt current general-purpose PWM power supply main control chips such as SG3525, UC3845, and TL494. The chip itself and the peripheral reference comparison and error calculation circuits are all existing mature designs. The high-frequency switching boost circuit 063 adopts the classic Boost boost topology, relying on MOS switching transistors, power inductors, and freewheeling diodes, and can specifically adopt a standardized industrial DC-DC boost circuit. The multi-stage filtering and voltage regulation is composed of cascaded LC and RC filter circuits, built using basic passive components such as capacitors and inductors, and belongs to the standard ripple suppression scheme of the back end of the switching power supply.

[0029] In this preferred solution, the working logic of real-time sampling of the voltage of the composite connection cable at the front end, dynamic voltage regulation of PWM closed loop, voltage drop compensation by boosting, and multi-stage filtering and voltage regulation output is used to specifically solve the problem of long line voltage drop when the markerless motion capture camera 01 is centrally powered. The voltage regulation and compensation unit 06 is installed and used near the point where the voltage drop exceeds the standard at a remote end.

[0030] During operation, by comparing the difference between the sampled voltage and the rated reference voltage, the voltage gap caused by the line voltage drop can be quantified, and the voltage amplitude that needs to be supplemented can be determined, avoiding blind voltage boosting or insufficient voltage boosting. Specifically, when the measured sampled voltage is lower than the rated reference voltage, the PWM control chip 062 increases the output duty cycle, and the high-frequency switching boost circuit 063 increases the conduction time, thereby increasing the output boost amplitude and making up for the line voltage loss. When the sampled voltage rises back to near the rated reference voltage, the duty cycle is reduced, the boost output is reduced, and a closed-loop dynamic voltage regulation is formed.

[0031] In this embodiment, the rated reference voltage is a preset target value inside the voltage regulation and compensation unit 06, such as 48V. The voltage regulation and compensation unit 06 always performs boost compensation towards this voltage.

[0032] As a preferred embodiment, the voltage regulation and compensation unit 06 further includes at least one of an overvoltage protection circuit, an overcurrent protection circuit, an overload protection circuit, or an overheat protection circuit. This allows for timely circuit disconnection in case of abnormal input voltage, short circuit, overload, or excessive device temperature rise, preventing front-end line faults from impacting the unmarked motion capture camera 01 and improving the operational safety of the voltage regulation and compensation unit 06 and the entire system. All of the above protection circuits can adopt existing circuit structures, which will not be elaborated upon here.

[0033] As a preferred embodiment of the above, the front-end switch 03 includes a synchronization trigger distribution module, which sends a synchronization trigger signal to the corresponding N markerless motion capture cameras 01 through a composite connection cable 05, so that the exposure timing of all markerless motion capture cameras 01 in the same group is consistent, reducing the acquisition synchronization error and thus ensuring the accuracy of subsequent 3D reconstruction data.

[0034] Example 2 like Figure 4 As shown, the method for networking unmarked motion capture cameras includes: Convert AC power to DC power and supply power to N unmarked motion capture cameras in parallel, where 5≤N≤15; The system synchronously completes power supply, image data interaction, and synchronous trigger signal transmission for a single unmarked motion capture camera. Data from N markerless motion capture cameras connected in a centralized parallel power supply is collected, processed, and then transmitted externally. Receive and aggregate several sets of data, and then transmit the aggregated data to the workstation. Unmarked motion capture cameras whose power supply voltage drop exceeds the preset standard are identified, and voltage compensation is performed separately for the identified unmarked motion capture cameras after drawing power from the centralized power supply side.

[0035] The technical effects achieved in this embodiment are as described in Embodiment 1 above, and will not be repeated here.

[0036] As a preferred embodiment of the above, such as Figure 5 As shown, the methods for determining whether the voltage drop of the unmarked motion capture camera exceeds a preset standard include: The full-load condition of the unmarked motion capture camera is used as the voltage judgment standard. The full-load condition is when the camera is in the highest frame rate acquisition mode and the matching infrared fill light is turned on at full power. Under full load conditions, when the voltage at the power supply terminal of the unmarked motion capture camera is lower than the set percentage of the rated operating voltage, it is determined that the voltage drop exceeds the preset standard, which is 85%-95%.

[0037] In this preferred solution, the full-load condition is the actual maximum power consumption of the unmarked motion capture camera. Using this condition to screen devices with excessive voltage drop can avoid misjudging the line voltage drop under light-load conditions and mistakenly adding voltage stabilization compensation units. This ensures the power supply stability of the remote unmarked motion capture camera under full load while reducing the installation of unnecessary components.

[0038] In some embodiments of the present invention, the set ratio can be specifically selected as 90%, that is, when the power supply terminal voltage of the unmarked motion capture camera is lower than 90% of the rated operating voltage, it is determined that the power supply voltage drop exceeds the preset standard.

[0039] As a preferred embodiment of the above, voltage compensation is performed separately for the identified unmarked motion capture cameras after drawing power from the centralized power supply side, including: The input voltage of the centralized power supply side is collected in real time to obtain the sampled voltage; The sampled voltage is compared with the pre-stored rated reference voltage to determine the voltage compensation amount. The PWM duty cycle is dynamically adjusted according to the voltage error to adaptively adjust the boost compensation amplitude. The voltage after voltage compensation is processed to remove noise and ripple.

[0040] The method for networking unmarked motion capture cameras has been further optimized, including: A unified synchronization trigger signal is issued to N unmarked motion capture cameras that are centrally connected in parallel, so that each unmarked motion capture camera can receive the trigger command synchronously and perform synchronous acquisition operations.

[0041] The technical effects achieved by the above preferred solutions are the same as those in Embodiment 1, and will not be repeated here.

[0042] Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to this invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
