Abstract
Be equipped with artificial antenna image sending module and wavelet compression module depending on signal madulation module and be equipped with the digital video image that 802.11n wireless bridge sends aerial camera shooting simultaneously.
Description
Technical field
This patent relates to a kind of digital camera and Wireless transceiver.
Background technology
Usually take photo by plane photography in order to shooting picture is sent to ground immediately, adopt the mode of wireless transmission, have to adopt and transmit analog picture signal, also have to adopt and transmit data image signal.Adopt the advantage transmitting analog picture signal mode to be that real-time is good, image delivers to ground at once, does not have time delay, and ground can carry out manual guidance by this picture signal and shooting picture is selected and controls, but be limited to transmission bandwidth, and image resolution ratio is lower.Adopt the advantage transmitting data image signal mode to be that image resolution ratio can improve, but shortcoming is that signal transmission exists time delay, and real-time is poor because needs carry out image Compression, is not suitable for the manual guidance carrying out aircraft under the environment having barrier.
Utility model content
The object of the utility model patent is to design not only having signal and transmitting real-time but also have high-resolution wireless image conveyer of a kind of photography that applies to take photo by plane.
The utility model patent adopts take photo by plane video camera and Standard Definition Television modulation module, artificial antenna image transmission module, wavelet compression module, 802.11n wireless bridge of 4K form and take and simulate SD video, meet the wireless base station apparatus of the wavelet compressed images signal of DCI@4K.
Realize the technical scheme of above-mentioned purpose: the dual-mode wireless image transfer apparatus that a kind of photography of taking photo by plane is used, as shown in Figure 1, video camera of taking photo by plane, television signal modulation module, artificial antenna image transmission module, wavelet compression module, 802.11n wireless bridge is comprised.Described video camera of taking photo by plane, for photographic images, exports 4K digital video image; Described television signal modulation module is used for digital video image to be modulated into standard television signal; Described artificial antenna image transmission module is used for standard television signal to carry out signal transmission in the mode of wireless transmission; Described wavelet compression module is used for digital video image to want the coded compressing image data becoming to meet DCI@4K; The wavelet compressed images signal meeting DCI@4K that described 802.11n wireless bridge is used for the output of wavelet compression module connects into WLAN (wireless local area network) with point-to-point interconnection and another 802.11n wireless bridge, carries out signal transmission.During use, 802.11n wireless bridge is equipped with omnidirectional antenna.
Adopt technique scheme, the technique effect that the utility model patent is useful is:
(1) can send without the picture signal of time delay and the picture signal of high definition simultaneously, make image not only can be used for navigation but also can be used for observation analysis;
(2) wireless bridge is adopted can to strengthen the transmission range of data image signal;
(3) ground is mixed receiver and just can be used, simple and convenient.
Accompanying drawing explanation
Fig. 1 is that dual-mode wireless image transmits block diagram.
Fig. 2 is that dual-mode wireless image transmits implementing circuit block diagram.
Embodiment
The dual-mode wireless image transfer apparatus that a kind of photography of taking photo by plane is used, comprise video camera 1 of taking photo by plane, television signal modulation module 2, artificial antenna image transmission module 3, TV signal antenna 4, wavelet compression module 5,802.11n wireless bridge 6, omnidirectional antenna 7, as shown in Figure 2.4K digital video image taken by video camera 1 of taking photo by plane, and the data image signal exported is connected to television signal modulation module 2 and wavelet compression module 5; Television signal modulation module 2 receives the data image signal from video camera 1 of taking photo by plane and is modulated into standard television signal and outputs to artificial antenna image transmission module 3; Artificial antenna image transmission module 3 signal from television signal modulation module 2 is converted to can wireless transmission signal and be transported to TV signal antenna 4; Signal from artificial antenna image transmission module is sent by antenna by TV signal antenna 4; Wavelet compression module 5 receives the data image signal from aerial camera 1, its compressed encoding is become to meet the compressing image data of DCI@4K, and outputs to 802.11n wireless bridge 6 in the mode of Ethernet bag; 802.11n wireless bridge 6 is configured to point-to-point interconnection, after the data receiving wavelet compression module 5, converts thereof into the wireless bridge signal of communication meeting 802.11n standard, is transported to omnidirectional antenna 7; Signal from 802.11n wireless bridge 6 is sent by antenna by omnidirectional antenna 7.
