In the present embodiment, described supervising device 2 is a kind of remote control unit, controls web camera 4 shooting monitoring region for far-end, so that this monitoring region to be monitored.
Described monitoring system 10 includes controlling module 100, receiver module 200, display module 300, sensing module 400 and modular converter 500. Described module is configured to be performed by one or more processors (the present embodiment is processor 30), to complete the present invention. Module alleged by the present invention has been the computer program code segments of a specific function. Memorizer 20 is for storing the data such as the program code of monitoring system 10.
Described control module 100 is for, after starting or restarting web camera 4, controlling web camera 4 moving lens 44 scanning monitoring region, with the picture that pans. Described monitoring region is the maximum magnitude that web camera 4 can be photographed by moving lens 44. In the present embodiment, the process in described scanning monitoring region is that from the lower left corner in monitoring region, camera lens 44 is started the progressive scan in " several " font (consulting shown in Fig. 2) to the right.
The percent information of the described receiver module 200 panoramic pictures and monitoring region for receiving web camera 4 transmission. In the present embodiment, described percent information is the Pan(left and right directions in the monitoring region of web camera 4) length of angular range and Tilt(above-below direction) height (consulting shown in Fig. 2) of angular range. Such as, in monitoring region, the height that length is 400, Tilt angular ranges of Pan angular range is 300.
Described display module 300 for being shown in display screen 22 by the panoramic pictures received, and records the size of panoramic pictures viewing area in display screen 22. Such as, panoramic pictures viewing area is 4 in the length of X-direction, and the height in Y direction is 3. In other embodiments, display screen 22 may be alternatively located on other electronic installations being connected with supervising device 2.
Described sensing module 400 is for sensing the position coordinates of the regional area that user selects on panoramic pictures viewing area. Such as, sensing module 400 senses the position coordinates of the regional area that user selects is (2,1). If display screen 22 is touch screen, then user directly can click this regional area with finger on touch screen. If display screen 22 is not touch screen, then user can select this regional area by modes such as mouse, keyboard, arrow buttons.
Described modular converter 500 is used for the size according to panoramic pictures viewing area and the percent information received, and this position coordinates is converted to coordinate corresponding in the monitoring region of web camera 4. In the present embodiment, modular converter 500, according to the panoramic pictures viewing area ratio at the length of the X-direction height in Y direction and height of Tilt angular range with the length ratio of Pan angular range and panoramic pictures viewing area, determines the ratio between two coordinate figures of two coordinate figures of this position coordinates and the corresponding coordinate in monitoring region.
Such as, above-mentioned panoramic pictures viewing area is 1:100 in the length of X-direction and the length ratio of Pan angular range, panoramic pictures viewing area is 1:100 at the height of Y direction with the ratio of the height of Tilt angular range, the then position coordinates (2 of this regional area, 1) being converted to the coordinate in monitoring region is (200,100).
Described control module 100 is additionally operable to control according to the respective coordinates being converted to the camera lens 44 of web camera 4 and moves to appointment position. Such as, control module 100 to control camera lens 44 to move to coordinate in monitoring region be the position of (200,100).
Consult shown in Fig. 3, be the present invention flow chart of monitoring method preferred embodiment. Described monitoring method is applied in supervising device 2, performs the program code of storage in memorizer 20 by processor 30 and realizes.
Step S10, after starting or restarting web camera 4, controls web camera 4 moving lens 44 scanning monitoring region, with the picture that pans. Described monitoring region is the maximum magnitude that web camera 4 can be photographed by moving lens 44. In the present embodiment, the process in described scanning monitoring region is that from the lower left corner in monitoring region, camera lens 44 is started the progressive scan in " several " font (consulting shown in Fig. 2) to the right.
Step S12, receives the panoramic pictures that web camera 4 transmits and the percent information monitoring region. In the present embodiment, described percent information is the Pan(left and right directions in the monitoring region of web camera 4) length of angular range and Tilt(above-below direction) height of angular range (consulting shown in Fig. 2). Such as, in monitoring region, the height that length is 400, Tilt angular ranges of Pan angular range is 300.
Step S14, is shown in the panoramic pictures received on display screen 22, and records the size of panoramic pictures viewing area in display screen 22. Such as, panoramic pictures viewing area is 4 in the length of X-direction, and the height in Y direction is 3. In other embodiments, display screen 22 may be alternatively located on other electronic installations being connected with supervising device 2.
Step S16, the position coordinates of the regional area that sensing user selects on panoramic pictures viewing area. Such as, the position coordinates sensing the regional area that user selects is (2,1). If display screen 22 is touch screen, then user directly can click this regional area with finger on touch screen. If display screen 22 is not touch screen, then user can select this regional area by modes such as mouse, keyboard, arrow buttons.
Step S18, according to the size of panoramic pictures viewing area and the percent information that receives, is converted to coordinate corresponding in the monitoring region of web camera 4 by this position coordinates. In the present embodiment, according to the panoramic pictures viewing area ratio at the length of the X-direction height in Y direction and height of Tilt angular range with the length ratio of Pan angular range and panoramic pictures viewing area, determine the ratio between two coordinate figures of two coordinate figures of this position coordinates and the corresponding coordinate in monitoring region.
Such as, above-mentioned panoramic pictures viewing area is 1:100 in the length of X-direction and the length ratio of Pan angular range, panoramic pictures viewing area is 1:100 at the height of Y direction with the ratio of the height of Tilt angular range, the then position coordinates (2 of this regional area, 1) being converted to the coordinate in monitoring region is (200,100).
Step S20, the camera lens 44 controlling web camera 4 according to the respective coordinates being converted to moves to appointment position. Such as, control camera lens 44 moves to coordinate in monitoring region is the position of (200,100).
Above example is only in order to illustrate technical scheme and unrestricted, although the present invention being described in detail with reference to preferred embodiment, it will be understood by those within the art that, technical scheme can be modified or equivalent replacement, without deviating from the spirit and scope of technical solution of the present invention.
