Definitions
- the present invention relates to a system, in particular for race timing, and more particularly such a system comprising an optical device installed at landline and in line with a crossing line of objects to project an image of this line on a photosensitive sensor.
- the invention also relates to a method of adjusting the alignment of such a system on an object passing line such as a finishing line of a race.
- This system includes a camera, a device storage and image processing, a box of command and a control screen.
- the camera includes a optical unit with which a photosensitive sensor is associated on which the image of the reference line is intended for be trained.
- the optical unit includes an optical objective conventional and the photosensitive sensor is formed of a bar, composed of a plurality of pixels juxtaposed in a single column, generally designated CCD bar (corresponding to the Anglo-Saxon designation "Charged Coupled Device ").
- the camera must be installed at a permanent extension of the reference line and perpendicular to it.
- the reference line must be in perfect alignment with the CCD bar of the camera.
- This alignment is generally carried out in two steps.
- a bench CCD bar optic with the optical device of the camera.
- the CCD bar is moved relative to the optical unit in order to be brought in overlay with a line of a crosshair of an eyepiece mounted on the camera's optical unit using different screw adjustment mechanisms. Once this adjustment made, the CCD bar is fixed in this position using mechanical means such as screws.
- the optical unit further comprises a mirror switching between a first position called operation, in which the plane of the mirror is clear of the optical path connecting the CCD bar to the objective and a second position, called adjustment in which the mirror is placed on said optical path and returns the image perceived by the objective, in this case the image of the reference line, on the eyepiece.
- operation in which the plane of the mirror is clear of the optical path connecting the CCD bar to the objective
- second position called adjustment in which the mirror is placed on said optical path and returns the image perceived by the objective, in this case the image of the reference line, on the eyepiece.
- the settings required by the camera when its assembly at the factory is long and delicate.
- the mechanical parts constituting the optical adjustment device by report to the CCD can distort and misalign the reticle of the eyepiece with respect to the CCD bar.
- the main aim of the invention is therefore to remedy the disadvantages of the aforementioned prior art in providing a system comprising a camera comprising a simple and inexpensive device for adjustment precise alignment of a photosensitive sensor of the type CCD bar on a line of passage of a race.
- the reticle is associated with control means via a comparator circuit receiving the image signal as an input and a reference signal from the control means and outputting a control signal, and the reticle can be moved over the image in response to control signal.
- the system further comprises means for switching the image signal either to the processing means or to the extraction means thus switching the system into one spatial and temporal operating mode respectively.
- switching means presents in particular the advantage of making it easy to check the system positioning at any time by switching simply the system from temporal to spatial mode.
- system alignment can be done by moving, for example using an electronic control, on a video image a reticle to superimpose it on the image of the passage line appearing on the image. So the alignment adjustment operations are simplified especially in that the implementation of mechano-optical mechanism delicate is completely eliminated.
- the alignment method of the invention can be, once the alignment steps have been completed, in a simple way to offer other possibilities operating the process such as timing.
- the invention is not not limited to this application and that it may be advantageously used in the context of any other application in which it is necessary to perform a alignment adjustment of a photosensitive sensor of the type CCD on an object passage line, for example in scanners or the like.
- FIG. 1 shows the principle of system according to the invention designated by the reference general digital 1.
- Runners 2 each evolving on a corridor 4 at a certain speed, pass a line of passage 6 which can be here the finish line of the race.
- a camera 8 is installed which is part of system 1.
- the camera 8 conventionally comprises an optical device 10 formed of a photo or video lens which can if if necessary be equipped with a manually operated zoom or remote control.
- the optical device 10 projects an image of the passage line 6 on a photosensitive sensor 12 behind the lens in a plane perpendicular to that of the figure.
- the photosensitive sensor is a CCD type sensor which is presented as illustrated in Figure 2 as a matrix of pixels 14 juxtaposed in rows L1-Ln and in columns C1-Cn.
- the sensor 12 is capable of supplying electrical signals 16 representative of the image projected by the device optical 10 and received by this sensor. These signals 16 will designated image signal in the following description.
- the sensor 12 comprises 750 lines and 480 columns. These sensors can be easily obtained in commerce, for example at Thomson.
- this sensor can be a color or black and white sensor depending on the application desired.
- the image signal 16 from the sensor 12 is supplied as input to processing means 18 via means of switching 20 when these are in a first position shown in solid lines in the figure, this position corresponding to a first operating mode of the system called spatial mode.
- processing means 18 output a processed image signal 21 to means display 22.
- These are provided to display a representative image signal image and are formed by a standard video screen or monitor such as PAL, NTSC or multimedia standard.
- multimedia standard we will include a digital output for a computer.
- the processing means 18 include an encoder 24, which codes the image signal to make it suitable for display on the monitor, as well as 26 to generate a reticle 28 which is also displayed on the monitor overlaying the video image or overlay in a digital image. These means 28 are able to generate on the image displayed by the monitor a vertical bar of small width, typically one pixel, and crossing the image from top to bottom which forms the reticle 28. Typically, the reticle can be formed by putting the part of the image signal coming from a column of determined pixels of the sensor in a state given by example in a color.
- the generating means 26 are associated, via a comparator circuit 30, with means of control 32 which allow in particular to control the horizontal displacement of the reticle 28 on the image.
- the order can be carried out via a user interface in the form of a keyboard 34 on which he can manually enter parameters of selection of a column of sensor 12 which will allow formation of the reticle at a given location on the monitor 22.
- the keyboard 34 is connected to the control means 32 by a control bus 36.
- the control means 32 are by elsewhere connected to the switching means 20 in order to control, via a switching signal 31, the mode of functioning of the system as will be described more in detail below.
- Comparator circuit 30 receives the signal as input image 16 which comes from the sensor as well as a signal reference 37 which comes from the control means 32, and outputs a control signal 38 which is applied on the one hand to the generating means 26 of the reticle, and on the other hand to extraction means 40 which will described in more detail below.
- the reference signal 37 is a signal representative of the position of the column pixels which corresponds to the desired position of the reticle on monitor 22.
- This signal 37 is supplied to means memory 42 forming part of the comparator circuit 30 and which store a representative numerical value of an ith column of pixels of the matrix 14 forming the sensor 12, this value corresponding to the parameters of the column of pixels entered by the user using of the keyboard 34.
- the storage means 42 are classics and can typically be formed by a registry or RAM or ROM.
- Memory or register 42 includes a default value of system activation, this value can for example be the one that corresponds to the central pixel column of the pixel matrix be the 240th columns in the special case of a matrix with 480 columns.
- Memory 42 outputs a signal 43 to a first input 44 of a comparator 46.
- the comparator circuit 30 further comprises counting means 48 of columns which receive as input the image signal 16 and output a signal of counting 50 to a second input 52 of comparator 46 which in turn provides the control signal 38.
- the column counting means 48 are advantageously formed by a counter by 480 which is resets at the start of a complete image or "frame", that is to say 50 or 60 times per second depending on the standard video used (PAL respectively NTSC).
- Comparator 46 is typically a comparator which provides the control signal when the count 50 is equal to reference signal 36
- the extraction means 40 also receive input the image signal 16 via the switching means 20 when these are in a second position shown in dotted lines in the figure, this position corresponding to a second mode of operation of the system says time mode.
- These means 40 are provided for extract image signal 16 in conjunction with the signal command 38 coming from the comparator circuit 30, electrical signals from a column of pixels of the matrix 12, which corresponds to the position of the reticle on the screen and to output a column signal 54.
- the column signal is then supplied to means operating 56 which can be trained for example with the image acquisition and processing circuit from a pixel column described in the patent EP-A-0 402 749.
- the extraction means 40 may advantageously be formed by a filtering circuit classic which only lets through part of the signal image 16 relating to the pixel column corresponding to the reticle based on control signal 38.
- the system according to the invention further comprises timing means 58 for reading at a frequency determined the signal column 54, or in other words the electrical signals from the pixel column defined by control signal 38, the pixel column forming an image representative of the line image projected on this column at a given time, the image of the line being in perfect superposition with the reticle defined above.
- the timing means 58 provide an extraction timing signal 60 as a programmable frequency binary signal by the control means 32.
- the column reading frequency is chosen by the operator as a function of the running speed of objects whose image it must retain, in this case in depending on the speed of the race.
- the operator has the keyboard on which he can manually enter the value of this frequency, the control means 30 serving as an interface between the keyboard and the timing means 58 and delivering to these last a timing control signal 62.
- the timing means 58 comprise a time base circuit associated with a microcontroller, these commercially available circuit, for example under the name Intel 80186 which combines these two components into a single integrated component.
- timing means 58 provide to sensor 12 of sensor timing signals 64 for manage the different read or acquisition speeds images also via the control signal timing 62 depending on the operating mode of the system. It should be noted in this connection that the speed acquisition is slow and fixed in the operate spatial and fast and variable in the mode of time operation.
- the display speed is standard, PAL, NTSC or multimedia video and when the signal is switched to time mode, the acquisition speed can be between 100 and 5,000 Hz i.e. the content of the column selected is refreshed 100 to 5000 times per second.
- the timing means 58 also manage the exposure time of the image saved.
- the system of the invention may further comprise means programmable amplification (not shown) which would be disposed between the sensor 12 and the means of switching 20 to change the contrast and brightness of the image that is displayed on the monitor and this for each color in the case of a color sensor.
- means programmable amplification (not shown) which would be disposed between the sensor 12 and the means of switching 20 to change the contrast and brightness of the image that is displayed on the monitor and this for each color in the case of a color sensor.
- the pixel matrix forming the sensor 12 is positioned to have the greatest number of pixels in columns than in rows. Similarly we prefer to scan the matrix in the direction of the columns rather than in the direction of the lines.
- the optical axis of camera 8 must be perfectly aligned with the line of passage of objects that we want to film in order, for example, to determine speed or time of passage of objects or competitors in the context of races, with the greatest precision.
- the matrix sensor 12 will also have been adjusted by compared to the camera housing 8 in particular so that the verticality of the pixel columns of sensor 12, i.e. confused with that of the walls of the camera housing. Note in this connection that the optical axis is defined by the direction perpendicular to the plane of the sensor
- Camera 8 equipped with a tripod or support (not shown) adjustable according to all degrees of freedom is firstly placed in the extension of the line of passage 6 so the optical axis of the camera is appreciably directed towards this line.
- the verticality of the pixel columns of the sensor 12 is adjusted by orienting the camera housing 8, for example using a spirit level, by acting on adjustment knobs and / or cranks provided on the tripod.
- the camera is engaged in spatial operation mode in acting on the switching means 20 via the keyboard 34 and the control means 32.
- the camera 8 reads, at a first frequency determined, the image signal 16 from the sensor 12 to form on the monitor or screen 22 an image by example a video image.
- the reading frequency is generated by the timing means 58 in response to the switching of the system to spatial mode via the means of command 32.
- the first frequency varies according to the standard video used and can be for example respectively 50 Hz and 60 Hz depending on whether the standard video is used PAL or NTSC. We can of course also use the multimedia standard.
- the video image of the passage line 6 and the environment of this line appear on the monitor 22. Note that the development and framing of the video image can be made during this surgery.
- the reticle 28 is therefore displayed at a position on the screen, which is determined by the value contained by fault in reference memory 42 when switching on.
- the reference value is the one that corresponds to the 240th column of pixels in the matrix 12 so that the reticle 28 is formed in the middle of the screen.
- the CR column is selected and corresponds to reticle 28.
- the column of pixels CR is the column of pixels that will be used when the the invention will be switched to the operating mode temporal.
- the image signal 16 is supplied in input to the extraction means 40 which receive by elsewhere the control signal 38.
- camera 8 reads, at a second frequency determined, the image signal 16.
- This reading frequency is generated by the timing means 58 in response when switching the system to time mode. This frequency is chosen, and entered by the user via the keyboard 34 and the control means 32, depending on the scrolling speed of objects on the line passage 6. Typically this second reading frequency varies between 100 and 5000 Hz.
- the extraction means 40 do not pass the image signal 16 only when the signal 38 is active to thus output the signal column 54 representative of the intensity profile image of the passage line 6 at a given instant.
- the column signal 54 comes from the column of CR pixels and exactly matches the position of the reticle 28 of the spatial operating mode.
