Problems solved by technology
The disadvantages of this patent application are: only the scenes of the main camera and the observation camera are shown, the operator can only estimate the position of the main camera with the naked eye, and the operator can only control the position of the camera in space through visual feedback, and the control cannot accurate
The disadvantages of this patent application are: the vector image representing the direction and size of the displacement cannot visually display the position of the camera in the working space, and the display only shows the moving state of the camera's position, but does not show the attitude of the camera in the working space, and does not show the camera's position in the working space. The captured image cannot intuitively adjust the pose and focus of the camera

Embodiment Construction
[0051] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0052] Refer to attached figure 1 Concrete steps of the present invention are as follows.
[0053] Step 1, install the camera and input the working parameters.
[0054] Before the camera can work normally, the camera must be installed. Select four points with the same horizontal height as the four calibration points at the bottom of the four flexible cable support columns, and install the camera on any one of the four flexible cable support columns. At the fixed point position, align the center of the camera lens with the calibration point on any one of the remaining three columns outside the camera installation column.
[0055] Before the camera works normally, it is necessary to input the length, width and height parameters of the camera’s intended working space, so that the flexible cable traction camera can be applied to different sizes of work sites. ...

A soft cable traction video camera position monitoring method solves the problem that display is non-visual, inaccurate to control and posture of the video camera cannot be displayed as a vector diagram standing for displacement direction and side is displayed only in the prior art and the problem of a less operable position controller when only vision feedback or position information is provided. The soft cable traction video camera position monitoring method includes steps of displaying a position coordinate, moving speed, length of four soft cables, horizontal moving animation, three-dimensional moving animation and posture arrows of a video camera on a screen of the position controller, and displaying video recorded by the video camera on a screen of an image processor; observing and monitoring the screens of the position controller and the image processor, and controlling moving and rotating of the video camera by shifting a position control lever and a posture control lever. The soft cable traction video camera position monitoring method has the advantages that positions and moving states of the video camera in a working space can be visually observed, moving of the video camera in the working space can be accurately controlled, and posture of the video camera is visually adjusted.
Description
technical field [0001] The invention belongs to the technical field of machinery, and further relates to a method for monitoring the position of a cable traction camera in the field of mechanical motion control. The invention can realize the real-time monitoring of the spatial position and attitude of the camera when the cable-drawn camera moves freely in the designated working space. Background technique [0002] In large and medium-sized venues, such as open-air singing and dancing parties, celebrations and football matches, the flexible cable traction camera is often supported by four columns fixed at the four corners of the venue, and each column is more than ten meters or even tens of meters high. The cable traction camera system can make the camera move continuously and smoothly at different heights above the site to track the shooting target, and can also hover over the site to shoot. The images captured by the flexible cable traction camera system can give the audie...
