Problems solved by technology
The technical solution of this application can solve the problem of video transmission delay, and the remote driving operator can see the equivalent real-time picture. However, when the operator responds, the control signal is sent through the remote control, and the control signal is transmitted to the remote control driving device. Control delays still occur
When the control signal reaches the remote control driving device, the remote control driving device has already traveled a certain distance, and accidents such as collisions may occur during the forward process

Embodiment Construction
[0054] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0055] The first embodiment is a delay correction method for a remote control driving device. The remote control driving device is provided with a zoom camera, and the zoom camera is used to output a video signal to the remote control. The remote control sends a video signal to the remote control driving device send control signals;
[0056] The delay correction method is as figure 1 shown, including:
[0057] The step of obtaining the driving speed of the remote control driving device, the driving speed being the velocity component of the remote control driving device along the optical axis direction of the zoom camera;
[0058] Steps to obtain the delay time;
[0059] A step of calculating a delay distance according to the travel speed and the delay time;
[0...

The invention provides a time-delay calibration method and device for a remote-control traveling device.The time-delay calibration method comprises the steps that the traveling speed of the remote-control traveling device is obtained; delay time is obtained; a time-delay distance is calculated according to the traveling speed and the delay time; a corresponding relation function between a reference time-delay distance and a reference focal length variable is obtained; a focal length variable is calculated according to the time-delay distance and the relation function; the focal length of a zoom camera is adjusted according to the focal length variable, wherein the delay time comprises first delay time during which a video signal is sent back to a remote controller from the remote-control traveling device and second delay time during which a control signal is transmitted to the remote-control traveling device from the remote controller.According to the time-delay calibration method and device for the remote-control traveling device, an analog-to-digital conversion delay of the video signal and a transmission delay in the signal transmission process are both calibrated, the control realtime performance of the control signal is further promoted by means of multiple settings of the delay time, and synchronization of video and control is guaranteed.
Description
technical field [0001] The invention relates to the field of remote control driving devices, in particular to a delay correction method used in remote control aircraft, remote control cars, remote control boats or robots, and a correction device using the delay correction method. Background technique [0002] Now remote control driving devices, such as remote control boats, remote control cars and remote control aircraft, are equipped with driving camera devices. After being processed in the device, the image is output on the display screen of the remote control device. [0003] When the remote control driving device is driving in an area beyond visual distance or not visible, the driving environment in front of the remote control driving device can be observed through the remote control display screen, thereby realizing remote manual control of driving. [0004] The image information acquired by the driving camera device will be delayed in the process of displaying it back...
