Still another condition is whether it has already been judged to be a front going vehicle (Step ST13). Fast Measure FMGPS Distance Measuring Device Vehicle Mount Kit. Fig. Figs. If the flag is already set (YES in Step ST22), this object is added to a list (candidate list) of candidates as the front going vehicle (Step ST24). Fig. It is preferable, however, to additionally consider the conditions in Steps ST12 and ST13 (together referred to as the third condition) and even more preferable to further consider all conditions in Steps ST10-ST15, as described above in order to make certain that the object is a vehicle. The item you've selected was not added to your cart. Fig. If the own vehicle is stopped, the object may be erroneously identified as a vehicle by the process of Step S12 et seq. The front going vehicle judging process is for judging which of the objects which have not been identified as road surface is the front going vehicle. After these processes are completed for all of the detected objects (YES in ST4), the front going vehicle judging process is carried out (Step ST5). In Step ST21, it is judged on the basis of the predicted shape of the road ahead as shown in Fig. In Step ST10, it is determined whether the distance to the detected object being processed (hereinafter sometimes referred to simply as "the object") is within a specified preset range or not. 14 is an example of measured data from which a front going vehicle is recognized and confirmed as a truck by data processing. Fig. As measured data obtained by a rightward scan of any frame are taken into the memory 18, an area for a confirmation flag for a newly detected object is assigned at a specified area of the memory 18 (initialization of the confirmation flag) (Step ST1). With its small footprint (3w x 1.5h x 1.75d), it mounts on your dashboard. wherein said second condition is that the difference between the distance to said object measured by a scan that is earlier than said later scans and is the highest or nearly the highest in the vertical direction and the measured distance to a front going vehicle corresponding to said object is within a predetermined range. For each of the objects for which a flag has been set (YES in Step ST2), Step ST3 is skipped. 4 is a block diagram of a laser radar (as an on-vehicle distance measuring device) embodying this invention. For example, it is judged from the output of the vehicle speed sensor 19 whether the own vehicle is moving with a speed of 5km/h or not to determine whether it is stopped or not. Still another condition is whether or not the absolute value of the difference between the measured distance to the object in the leftward scan (up) and the distance to the corresponding front going vehicle is 5m or less (Step ST15) because if this difference is within a certain predetermined range (such as 5m or less), the probability of the object being a vehicle increases. 12 whether or not there is an object within the own traffic lane. The speed of the object relative to the road surface is obtained from its speed relative to the own vehicle that can be calculated from the difference between the measured distance from the previous frame and that from the present frame. 10 shows a routine for the vehicle confirmation process. 9 is a flowchart of a data processing routine as a whole. 2003, no. Thus, the road surface judging process can be carried out by extracting these characteristics from a received light signal. If a front going vehicle is confirmed, the routine for the measured data obtained by the rightward scan of this frame is completed. Over dit object zijn geen vragen of antwoorden geplaatst.

Next, a routine for data processing is explained in detail with reference to Figs. If this speed relative to the road surface is less than a threshold value, there is a high probability that it is not a vehicle. The shape of the road ahead may be obtained by processing an image of the front taken by the camera or by means of a navigation system. In Step ST20, the shape of the road in front is predicted from the yaw rate measured on the basis of the output from the gyroscope 20. Unless the object was judged to be a front going vehicle in the previous frame, probability is low that it is a vehicle. One rightward scan and one leftward scan forming one frame, as explained above, the process is repeated in units of three frames. vehicle-mounted distance measuring device was developed by a paving contractor for contractors. Fig. De verkoper neemt de volledige verantwoordelijkheid voor deze aanbieding.

If the object is determined to be outside the aforementioned range (YES in Step ST10), it may be concluded that the object is not a road surface but is a vehicle and a confirmation flag assigned to this object is set (Step ST19). View cart for details. 2 and 3 show situations where laser light emitted from a laser radar is not reflected by the reflector on a front going truck but is reflected by its other parts and detected. This range is specified as that in which the object may be a road surface and may be set as less than 20m such as 5-20m. Something went wrong. If it is judged that there is an object within the predicted own traffic lane (YES in Step ST21), it is examined whether or not a confirmation flag has been set regarding this object (Step ST22). 6 shows the optical paths through the light projection and receiving lenses moved by the scanner. If the object has been identified as a front going vehicle continuously for a plurality of frames over a specified length of time (such as 10 seconds), probability is high that it is a vehicle. Although many conditions are examined in Steps ST10-ST15, some of the conditions are more conclusive than the others. FastMeasure Distance Measuring Device Vehicle Mount Kit VeRO: Bescherming van intellectuele eigendomsrechten. After all objects are thus processed (YES in Step ST25), the object at the shortest distance is selected out of the candidate list to be judged as the front going vehicle (Step ST26), and a relevant judgment flag (judgment as front going vehicle) is set. 8 is a drawing for showing a routine for processing rightward and leftward scans. - Backlight 8-digit display is 2 1/8" wide x 5/8" tall. 9, 10 and 11 are flowcharts for showing a routine for processing measured data. If all of the conditions considered above are satisfied, it is reasonably safe to conclude that the object in question is a vehicle and a confirmation flag is set (Step ST16) for this object. Processes carried out for each frame include the "vehicle confirmation process", the "front going vehicle judging process" and the "road surface judging process". In this example, the front going vehicle is judged as a road surface at time intervals 1.5s - 2.2s, 2.6s - 3.6s and 6.6s - 7.2s by the road surface judgment task but since the confirmation flag is set at 0.2s, the road surface judgment flags in the set condition are ignored and the relevant judgment flag for judgment as front going vehicle is maintained in the set condition. {"modules":["unloadOptimization","bandwidthDetection"],"unloadOptimization":{"browsers":{"Firefox":true,"Chrome":true}},"bandwidthDetection":{"url":"https://ir.ebaystatic.com/cr/v/c1/thirtysevens.jpg","maxViews":4,"imgSize":37,"expiry":300000,"timeout":250}}. Since the laser light does not reach the road surface immediately in front, the starting point of the road judgment range is some distance away. If an object for which the confirmation flag has not been set is judged to be a road surface in Step ST23 (or the road surface judgment flag is set), nothing is done to such an object. In the vehicle confirmation process, if an object is once recognized as a vehicle, a confirmation flag is set for this object and thereafter thisobject is confirmed as a vehicle. If the center of the front going vehicle is off the center of the traffic lane of the own vehicle by less than one half of the width of the traffic lane, for example, it may be concluded that the front going vehicle is traveling within the own traffic lane. It is designed to help contractors quickly, easily and accurately measure in the field right from the comfort of your car. 1996, no. The distance measuring device of claim 2 wherein said vehicle confirming means, if said object is once judged to be outside said specified preset range, confirms said object to be a vehicle in scans carried out thereafter. In what follows, this range is referred to as the "road judgment range".
