Definitions

  • the invention relates to a method for determining the time between the start and finish of competitors, vehicles or the like.
  • a recording camera with a playback device for still images and preferably with a monitor, a timer that the running time during camera operation in the jumps corresponding to the individual images is faded into these individual images and displays the respective time of the individual recording from still image to still image, and a light barrier or the like.
  • sensors are provided in accordance with a target line and the recording camera still images in delivers a fixed time interval of preferably four hundredths of a second and is set up in alignment with the finish line.
  • the intervals of the time information correspond to an estimated average speed of the competitors, in order to be able to determine the times of the competitors arriving behind the winner.
  • an estimated average speed of the competitors is used, not the real time, especially in the area of the finish line, so that the accuracy of the times of the competitors coming behind the winner naturally suffers.
  • the time of the second or third of a competition can still be considerable, especially on short running routes such times should be accurate to a hundredth of a second.
  • This procedure thus results in a very precise and precise target time, for example of the winner of a competition, and also allows us to produce a corresponding document from the still image, i.e. to record this victory process.
  • this results in the actual speed of such a competition in the finish area, so that just behind the first competitor arriving, who due to a certain overlap with the winner cannot trigger the light barrier at the finish, due to the distance difference with respect to their finish time to one hundredth Can be determined exactly second, which is explained in more detail below.
  • the target time of the following competitors can also be determined to the nearest hundredth of a second based on the two displayed times and the knowledge of the true target time of the first competitor, without the need for very complex technical, visual and arithmetical measures.
  • the method according to the invention can be designed in such a way that for each competitor, every vehicle or the like, which has at least one picture sequence time compared to a previous competitor or vehicle triggering the light barrier appropriate distance and also has a clear distance from a previous competitor or vehicle, again the light barrier or the like. and triggering the fade-in of the second time over at least one image sequence is triggered while crossing the target line.
  • the previously described method for determining the target times of several closely spaced competitors can be used again for a somewhat slower group of competitors, a group of runners or a group of vehicles. It is advantageous that the actual speed of these competitors, which is now lower than that of a first victory group, is used as a basis.
  • the method according to the invention can be implemented and carried out in a particularly simple manner by the fact that the respective moving object - competitor, vehicle or the like.
  • distance is divided into equal fractions corresponding to one hundredth of a second, with a picture sequence of four hundredths of a second between two successive pictures is divided into four equal sections, this division for each Object that triggers the light barrier is carried out.
  • the lower speed of a competitor or a group of competitors arriving later than a competitor arriving earlier is taken into account, which is much more just and precise than the average speed previously assumed for all participants in a competition, according to which the arrival time of the competitors arriving after the winner has so far been all was estimated.
  • the target time of the second runner or competitor can be read off immediately. This is possible to an accuracy of one hundredth of a second if the scale divided into sections corresponding to one hundredth of a second, which is used to precisely determine the target time of the object, for example a runner, is electronically determined or calculated and at least superimposed on the target images. This is possible very inexpensively with today's modern electronic means.
  • the invention and above all to solve the problem of being able to determine the target times as inexpensively as possible and also to be able to document them in the image also include a device for carrying out the above-described method, which is essentially characterized in that a video camera is used as the camera a video recorder, a monitor and preferably a printer are also provided, the camera having shutter speeds of less than a hundredth of a second, preferably five hundredths of a second (1/500) or thousandths (1/1000) of a second, and that the video recorder allows the switching back and forth of still pictures at the moment of a full picture together with superimposed time information and such a time picture provided with a time picture can be printed out by the printer and that at least two synchronously running time generators are provided, which are between the camera and the Video recorders are arranged.
  • the monitor mentioned can be provided in the camera itself or else separately and is used to search for the still image (s) of interest and / or to evaluate the target times directly on the screen itself.
  • Video cameras, video recorders, monitors and printers are relatively inexpensive devices, with only the camera having to take appropriate shutter speeds of the lens into account so that the rapid sequence of images in each case delivers sufficiently sharp images.
  • Printers are also on the market, which can take enough shades of gray into account in order to be able to print out a video camera image with sufficient clarity.
  • At least two light barriers preferably working on an infrared basis, can be provided, spaced one above the other and above the target line are arranged that a pulse triggering to stop the fade-in of the target time takes place only when both light barriers are interrupted. This ensures that a competitor who is actually behind the first competitor does not trigger the finish time prematurely by an outstretched hand or arm.
  • a further embodiment of the device can consist in that at least one further light barrier or the like. is provided at a distance from the target for starting the recording process of the camera shortly before the first competitor arrives at the target. This saves the camera running during the entire race and having to take a correspondingly large number of pictures, which also makes evaluation more difficult after the competition.
  • a preferably adjustable time delay element can be provided for the automatic shutdown of the camera, so that not too many pictures are taken beyond the end of the competition.
  • the features and measures of claim 19 allow the scale to be adapted to the perspective reproduction of the target image, and the sections corresponding to 1/100 sec. Can therefore be shortened according to the perspective shortening depending on the distance of the career from the camera.
  • This video camera 6 is connected to a video recorder 9 via a line 7 and two time generators 8. At the same time, the light barrier receiver 5 is also connected to these time generators 8. In addition, a time measuring device 10 can also be seen, which is also connected to the time generators 8 and is used for checking.
  • the second runner 18 was one hundredth of a second slower than the first runner 15 or two hundredths of a second faster than the last runner 16.
  • the third rotor 19 lies exactly between the second and the fourth rotor 16 in order to clarify the principle. A closer arrival than at intervals of one hundredth of a second can hardly be distinguished by normal recordings, so that this results in very high accuracy, for example for a sprint competition.
  • the marking lines 29 u with the scale 22 with starting from a common vanishing point 31. 30 is arranged on a transparent support, which is arranged in front of a screen of the monitor 11 and / or above a printed target image 28.
