Description

  The present invention relates to an image display method by fluctuation correction and a remote control system for a model car or the like using the method, and more specifically, an image display method by fluctuation correction and an operator of an operation machine using the method. The present invention relates to a remote control system for a model car or the like having a remote control function for remotely controlling the speed of a traveling body such as a model car or controlling the speed by maneuvering.

  A remote camera device and a remote monitoring system device that can change an imaging region and the like by remote operation have been proposed. As such a remote camera device, for example, a remote camera device that can correct the control overshoot amount of the monitoring camera unit due to transmission delay or signal processing delay has been proposed (Japanese Patent Laid-Open No. 6-38087). As a remote monitoring system device, for example, an image to be displayed on the receiving side when the camera is operated is shifted and displayed so as to approach the range that the camera is capturing at that time, as if there is a delay in the image. A monitoring system device has been proposed in which a display range is processed so that it does not appear and a delay due to remote operation of the camera is not felt (Japanese Patent Laid-Open No. 2002-185556).

  However, these technologies are premised on moving image transmission via a wired line, and by performing correction for a fixed delay time, it is possible to transmit a moving image with no sense of incongruity. However, when moving image transmission by the Internet or wireless LAN is performed. In this case, since a uniform communication speed cannot be obtained, fluctuation occurs in the arrival time of the moving image data.

  In other words, the drawing timing varies due to variations in communication delay, and data loss sometimes occurs due to a communication error. As a result, a situation in which the moving image feels strange (see FIGS. 20 to 22) occurs.

  For the reasons described above, when such a camera is mounted on a traveling body such as a model car and operated while watching the image from the camera on a monitor such as a personal computer, this fluctuation is a discontinuity of moving image data. As a result, the operator cannot predict the movement of the model car or the like, and the accurate operation cannot be performed, and the maneuverability of the remote operation is deteriorated.

  Conventionally, as a countermeasure, a method of suppressing fluctuation by accumulating moving image data in an amount that covers the fluctuation change range on the receiving side is employed. However, in the case of this method, there arises a problem that a moving image delay corresponding to the accumulation of moving image data occurs.

  The in-vehicle computer 11 is a CPU that controls each device and calculates / processes data. An F-ROM that cannot be erased once written but cannot be erased even when the power is turned off, a RAM that uses semiconductor elements, and an internal clock 13 , A video capture unit 12, an image compression unit, a sensor input unit 16, a motor control unit 15, and a wireless LAN communication unit 14.

  The in-vehicle computer 11 is connected to a camera 5, a vehicle speed sensor 6, a battery 7, a servo 8, and drive motors 9 and 9a (see FIGS. 2 and 3). As shown in FIG. Processing of information to be transmitted to and processing of information received from the operation machine 2 are performed.

  Processing of information to be transmitted to the operation machine 2 includes image compression processing for compressing the image by adding the time stamp value of the internal clock 13 to the image from the video capture unit 12, vehicle speed and battery obtained by the vehicle speed sensor 6. There is a sensor acquisition process for acquiring a voltage value as sensor information. Processing of information received from the operation machine 2 is motor control processing, and the servo 8 and the drive motors 9 and 9a are controlled according to the received control information.

  The operation machine 2 of the present embodiment displays a predetermined drawing area in the video of the in-vehicle camera 5 on the monitor. And the function of recognizing and judging the state of the model car 1 from the detection result of the sensor etc. installed in the model car 1, and outputting the vehicle camera image and the speed meter / battery remaining amount display according to the result, This is executed in conjunction with image information and sensor information from the model car 1. For example, processing for receiving image drawing information such as “image data, time stamp, vehicle speed, battery voltage value” is performed, and image information and sensor information included in this image drawing information are determined, and the next video is displayed. Perform the appropriate process.

Here, the image display method by fluctuation correction according to the present invention employed in the above system will be described in more detail. The image display method displays the received image on the monitor for enabling the traveling body to be remotely controlled while viewing a monitor display of an image from a camera of the traveling body such as a model car received via a network. In the operation machine to perform,
The received image is drawn on the monitor at a predetermined drawing timing interval, and the drawn image is a predicted image obtained by delaying the received image.

  The delayed predicted image is a pseudo image after the delay predicted time has elapsed, which is obtained by subtracting the time stamp added to the image information received at that time from the system time at the drawing timing. The image is obtained by subjecting the received image to image processing based on sensor information such as the estimated delay time, vehicle speed, steering angle, battery voltage value, etc., and the image processing is based on the sensor information. The image is zoomed and / or shifted left and right.

  This fluctuation correction method will be described in detail with reference to FIGS. In FIG. 5, Sa, Sb, Sc, Sd, and Se in the stage of the sending side image indicate imaging times at the time of capturing an image from the camera, and Sa, Sb, Sc, Sd, and Se in the stage of fluctuation are image information. Represents a time stamp to which an imaging time at the time of capturing an image from the camera is added, and Ta, Tb, Tc, Td, and Te in the receiving image drawing stage indicate the drawing timing time.

  In receiving image drawing, delayed prediction images are drawn at equal intervals, so there is no variation in drawing timing, in other words, there is no fluctuation and a smooth moving image can be obtained. The estimated delay time t is a time TS obtained by subtracting the time stamp S added to the image information received at that time from the drawing timing time T.

As shown in FIG. 6, the operation machine 2 has a function of designating a drawing area on the received image and transferring the range to the video memory. This function makes it possible to display an arbitrary area of the received image.

  FIG. 7 illustrates changes in the drawing area when the model car 1 goes straight, which is displayed on the monitor of the operation machine 2 when the model car 1 goes straight from point A to point B. The change in the area being shown is shown. As can be seen from the change in the drawing area, when the model automobile 1 simply goes straight, it is only necessary to zoom to the center without changing the center of the viewpoint with respect to the received image. The zoom amount in this case is calculated from the vehicle speed that is sensor information.

  Further, FIG. 8 explains the change of the drawing area when the model car 1 turns to the right, and there is an operation machine when the model car 1 moves from point A to point B so as to make a right turn. The change of the area | region displayed on 2 monitors is shown. As can be seen from the change in the drawing area, when the model automobile 1 turns to the right, the received image may be zoomed while gradually moving the center of the viewpoint to the right. The zoom amount and shift amount in this case are calculated from the vehicle speed and the steering angle, which are sensor information.

First, in the model car 1, a time stamp by the internal clock 13 is attached to the camera image and image compression processing is performed, and this image information is used as first data transmitted to the operation machine 2.

  Further, the vehicle speed value obtained by the vehicle speed sensor 6 and the battery voltage value are captured by the sensor capture process, and are used as second data transmitted to the operation machine 2 as sensor information.

  The image information generated by the image compression process and the sensor information generated by the sensor capture process are transmitted by the communication process as information transmitted to the operation machine 2. The operation machine 2 receives this information through communication processing, and passes the image information to the image expansion processing and the sensor information to the image processing processing.

  In the image processing, the image data in the image information is expanded and transferred to the image processing. In the image processing, an image to be drawn on the monitor is generated from the decompressed image data, time stamp, and sensor information, and is output to the monitor.

  When the information is received, it is confirmed whether it is system connection information from the operation machine 2 (S102). If it is system connection information from the operation machine 2, it is confirmed whether the authentication code is normal. (S103).

  If the connection code is normal, connection response information is transmitted to the transmission source operation machine 2 to switch the system state to connected (S104, S105), and the internal clock 13 is set to the system time data in the system connection information ( S106).

  If the information received from the operation machine 2 is not system connection information (S102), if it is control information (S107), it is checked whether or not the system state is connected (S108). If the system is connected, the control information is transferred to the motor control process (S109), and the internal clock timing process is performed (S110). If a control information reception error occurs (S111), the system state is switched to unconnected (S112).

  When the system information is not received, on the contrary, it is checked whether there is transmission information to the operation machine 2 (S113). If there is transmission information, it is confirmed whether the system state is connected ( S114), transmission information is transmitted (S115).

  The image compression processing of the in-vehicle computer 11 according to the present invention will be described with reference to the flowchart of FIG. The in-vehicle computer 11 judges whether or not it is connected to the operation machine 2 on the system during normal times (S201), and if connected, starts video capture (S202). The captured image is compressed (S203), and a time stamp generated from the internal clock 13 is added to create image information (S204, S205), which is transferred to the wireless LAN communication process (S206).

When the control information is received, the drive motors 9 and 9a and the servo 8 are output to be controlled in accordance with the drive motor value and servo position information included in the control information (S302, S303).

  In order to use the vehicle speed and battery voltage value immediately after being controlled in the motor control process as sensor information to be transmitted to the operation machine 2, when the drive motors 9, 9a and servo 8 are controlled in the motor control process, Sensor input processing is started (S304).

  When the sensor input unit 16 receives a process start command by the motor control process of the motor control unit 15 (S401), the vehicle speed is read from the vehicle speed sensor 6 and the battery voltage is read from the battery 7 (S402, S403). Information is created (S404), and sensor information is transferred to the wireless LAN communication unit 14 in order to transmit the sensor information to the operation machine 2 (S405).

  The internal clock adjustment process of the in-vehicle computer 11 according to the present invention will be described with reference to the flowchart of FIG. In the internal clock timing processing, the time difference between the system time of the internal clock 13 and the operation machine 2 is calculated from the transmission time of the control information and the communication delay time, and the timing time is calculated (S501 to S503). The timing time is set to 1/20 of the time difference to absorb a sudden change. This process is performed when the operation machine 2 is connected to the system.

  If the calculated timing is less than 1 ms, the internal clock 13 is not reset, but if it is 1 ms or more, the internal clock 13 is reset by adding the timing to the time of the internal clock 13 (S504, S505). ).

  The operation machine 2 is a personal computer in which a program for remotely operating the model car 1 is stored. An operator can remotely control the model car 1 by operating the operation machine 2.

  Next, processing of the operation machine 2 according to the present invention will be described. As shown in FIG. 14, the processing performed by the operation machine 2 is roughly divided into processing based on data transmitted from the model car 1 and processing based on input from the game controller 3 by the operator.

In the wireless LAN communication process of the operation machine 2, it is checked whether or not the connection with the model car 1 is maintained during normal times (S601).

  When the connection with the model car 1 is not maintained, it is determined whether or not the specified time has elapsed since the transmission of the system connection information transmitted at the previous connection (S602). Transmits the system connection information again (S603).

  If connection response information is received from the model car 1 (S604), it is determined from the response code whether the connection is normal (S605). If the connection is normal, the system status is being connected. (S606).

  When the connection with the model car 1 is maintained (S601), it is always checked whether there is information received from the model car 1 (S607). If the information received from the model car 1 is image information (S608), the image information is transferred to the image expansion processing program (S609).

  If the received information is not image information but sensor information (S610), a communication delay time is calculated from the current time and communication time (S611), the sensor information is transferred to the image processing (S612), and a communication monitoring timer is set. Reset (S613).

  When there is no reception information from the model car 1, it is checked whether or not there is transmission information to the model car (S614). If there is transmission information, the transmission information is sent (S615) to monitor communication. The timer is reset (S616). When the state in which there is neither reception information nor transmission information continues and the communication monitoring time is timed out (S617), the system state is switched to unconnected (S618).

  The image expansion processing of the operation machine 2 according to the present invention will be described with reference to the flowchart of FIG. In the image expansion process of the operation machine 2, it is on standby in preparation for the reception of image information from the model car 1 during normal times (S 701).

In the image processing processing of the operation machine 2, when an image that has been subjected to image expansion processing is updated while connected to the system (S801, S802), first, the time of the time stamp stored in the updated image is set to the current time. The time subtracted from the system time, that is, the drawing delay time is calculated (S803). When the drawing delay time is calculated, the image enlargement ratio is calculated from the drawing delay time and the vehicle speed (S804), and the image right / left shift amount is calculated from the drawing delay time and the steering position (S805).

  Then, a drawing area is designated from the calculated image enlargement ratio and image right / left shift amount (S806), and is transferred to the video memory (S807). On the other hand, based on the vehicle speed data and the battery voltage data in the sensor information, the speedometer and the remaining battery charge are overwritten (S808).

Then, the acquired steering value is converted into a steering position, and the accelerator / brake pedal value is converted into a drive motor value, which is used as a control value for transmission to the model vehicle 1 (S903).

  If there is no change in the converted control value (S904) and there is no transmission history for 500 ms or more after the previous transmission of control information (S905), the control information is created from the current control value and transferred to the wireless LAN communication process. (S906). If there is a change in the converted control value, control information is created from the new control value and transferred to the wireless LAN communication process (S906).
