Description

[Technical field]

[0001] The present invention relates to a technical field of measuring the movement state of a carrier, and more particularly to a measuring system for the start and end points of a carrier movement path that accurately measures the start and end points of the carrier movement path. [Background technology]

[0002] Car racing is a very popular sport these days, and the winner of the race is determined mainly based on the length of time spent moving around the course. The time it takes to leave the starting line and the time it takes to reach the finish line are important factors in determining the winner of the race. For this reason, timers are installed at modern race venues.

[0003] Current timers include electromagnetic induction timers and satellite signal positioning timers. Current electromagnetic induction timers are either embedded in the ground or installed in the air. Timers with this type of installation need to be installed in two fixed locations. Therefore, if the start and end points of a race are changed, the timer needs to be relocated. Timers installed in the air are easy to move and are not restricted to a fixed location, but are easily affected by weather and may cause problems with the stability of the installation structure. Current satellite signal positioning timers are easily affected by atmospheric conditions and terrain objects, and may cause problems with location information drift. Summary of the Invention [Problem to be solved by the invention]

[0004] SUMMARY OF THE PRESENT EMBODIMENT It is therefore an object of the present invention to provide a measurement system for accurately measuring the start and end points of a carrier's travel path. [Means for solving the problem]

[0005] A measuring system for the start and end points of a carrier movement path according to an embodiment of the present invention is installed on a carrier and includes a processor, a high-speed image capture unit, a satellite positioning unit, an image identification unit, and a display unit. The high-speed image capture unit is electrically connected to the processor. The satellite positioning unit is electrically connected to the processor and receives satellite signals to generate position data of the carrier. The image identification unit is electrically connected to the processor. The display unit is electrically connected to the processor. When a specific structure exists on the ground and the position data is within a predetermined range, the processor activates the high-speed image capture unit to capture the same frame image of the standard line and the specific structure as a judgment image, and determines the start point, end point, and travel time of the carrier movement path based on the change in the distance between the standard line and the specific structure on the ground in the judgment image, and displays the start point time, end point time, and travel time all on the display unit.

[0006] According to another embodiment of the present invention, a measuring system for measuring the start and end points of a carrier movement path includes a first host, a second host, and a third host. The first host is installed on a first carrier and includes a first processor, a first electromagnetic wave transmitting and receiving unit, and a first display unit. The first electromagnetic wave transmitting and receiving unit is electrically connected to the first processor and transmits and receives measurement electromagnetic waves. The first display unit is electrically connected to the first processor. The second host is installed on the ground and includes a second processor and a second electromagnetic wave transmitting and receiving unit, and is electrically connected to the second processor and transmits and receives measurement electromagnetic waves. The third host is installed on the ground and includes a third processor and a high-speed image capture unit. The high-speed image capture unit is electrically connected to the third processor. The first processor calculates the change in intensity of the electromagnetic wave received by the first electromagnetic wave transmitting and receiving unit, or the second processor calculates the change in intensity of the electromagnetic wave received by the second electromagnetic wave transmitting and receiving unit to determine the start and end times of the movement path of the first carrier, and the start time, end time, and path time are all displayed on the first display unit. When the intensity of the electromagnetic waves reaches a predetermined value, the high-speed image capture unit captures the same frame image of the standard line and the first carrier as a judgment image, and determines the start point of the carrier's movement path, the end point of the movement path, and the movement time based on whether or not there is a change in the distance between the standard line and the first carrier in the judgment image. Effect of the Invention

[0007] The system of the present invention solves the problems encountered in conventional technology, such as inaccuracy of position information due to environmental influences, inability to accurately measure the time of the start and end points of a carrier's travel path, and difficulty in constructing and installing a measurement system when the start and end points fluctuate.

[0009] 1, 2, 3, and 4 are diagrams showing a measuring system for the start and end points of a carrier movement path according to an embodiment of the present invention. The measuring system 1 for the start and end points of a carrier movement path according to this embodiment is attached to a carrier H, which is a race car for racing, but is not limited thereto, and other types of carriers such as motorcycles, bicycles, ships, or aircraft can also be used. As shown in FIG. 1, the carrier H runs to the vicinity of the start line S of the race, which is a grid structure with black and white stripes.

[0010] As shown in FIG. 2, the carrier movement path start / end point measuring system 1 according to this embodiment includes a processor 10, a high-speed image capture unit 20, a satellite positioning unit 30, an image recognition unit 40, and a display unit 50.

[0011] The high-speed image capture unit 20, the satellite positioning unit 30, and the display unit 50 are all electrically connected to the processor 10. The image identification unit 40 is a program module, which is loaded and executed by the processor 10. The satellite positioning unit 30 receives satellite signals transmitted from the satellite SA and generates position data of the carrier H. The satellite positioning unit 30 is a GPS chipset and receives satellite signals of the Global Positioning System (GPS), but is not limited thereto, and can also receive satellite signals of other satellite positioning systems, such as the Chinese Beidou system, the Russian GLONASS system, or the European Galileo system.

[0012] The high-speed image capture unit 20 according to the present embodiment includes a high-speed camera that captures images at a very high frame rate per second. Currently available high-speed cameras have a capture speed of 30 fps, 60 fps, 120 fps, and 240 fps, and can be set to a maximum of 1000 fps.

[0013] The satellite positioning unit 30 according to this embodiment is a module that assists the high-speed image capture unit 20. At both the start and end points of the circuit according to this embodiment, a specific structure (a grid structure with black and white stripes) of the start line S shown in FIG. 1 is installed. The processor 10 compares the position data generated by the satellite positioning unit 30 with a preset position data range, and when the position data generated by the satellite positioning unit 30 is within the preset range, for example, when the carrier H enters a reserve position near the start line S, as shown in FIG. 3, the processor starts the high-speed image capture unit 20 to start capturing the same frame image F of the standard line L and the specific structure on the ground (for example, the start line S) as a judgment image. This preset position data range can be input from an input unit (button or touch screen) of the carrier H attached to the measurement system 1 of the start and end points of the carrier movement path according to this embodiment, or can be input from a mobile device M.

[0014] The standard line L in this embodiment is a marked line on the high-speed camera lens of the high-speed image capture unit 20. The image recognition unit 40 determines the start point, end point, and travel time of the movement path of the carrier H based on the change in distance between the standard line L in the judgment image and a specific structure (start line S) on the ground, and the start point time, end point time, and travel time are all displayed on the display unit 50.

[0015] As shown in FIG. 4, the image identification unit 40 determines that the time corresponding to the judgment image where the distance between the standard line L and the specific structure on the ground (start line S) changes from no change is the start point of the movement process of the carrier H. For example, assuming that the high-speed camera is 100 fps, after the high-speed image capture unit 20 starts capturing images, in FIG. 4, the time of the first judgment image F1 is 15:05:00, the time of the second image F2 is 15:05:01, and the time of the 50th image F50 is 15:05:50. In the first image F1 and the second image F2, there is no change in the distance between the standard line L and the specific structure on the ground (start line S), but in the 50th image F50, the distance between the standard line L and the specific structure on the ground (start line S) begins to decrease. Therefore, it is determined that carrier H has started moving, and the time 15:05:50 corresponding to the 50th image F50 is the starting point of the carrier's movement path, and the time of the starting point is also determined to be 15:05:50.

[0016] Similarly, when the carrier approaches the end point, the processor 10 activates the high-speed image capture unit 20, and the distance between the standard line L and the specific structure on the ground (the goal line) in the captured judgment image continues to change until it falls within a certain range, compared with the position data generated by the satellite positioning unit 30 when the carrier approaches the goal line, which indicates that the carrier has passed the specific structure on the ground (the goal line), and the time corresponding to this judgment image is determined to be the end point of the carrier H's travel journey.

[0017] In some races, the carrier runs a certain number of laps on the same course, and the start and finish lines are the same ground feature, and the carrier repeatedly passes the ground feature of the start or finish line, which can be used as evidence that the carrier has completed the race. Also, if there is a ground feature between the start point and the finish point that is close to the start point or the finish point, the processor 10 can use the position data generated by the satellite positioning unit 30 to determine not to activate the high-speed image capture unit 20.

[0018] The starting time, the ending time and the journey time are all displayed on the display unit 50 and can also be transmitted using the wireless transceiver unit and displayed simultaneously on multiple mobile devices M via the network N or sent to the cloud server SE for storage.

[0019] The system 1 for measuring the start and end points of the carrier's travel may also include an acceleration sensor 60, which is electrically connected to the processor 10 and generates acceleration data when the carrier H starts or stops moving. The processor 10 determines the start and end points of the carrier H's travel based on the value of the acceleration data. The acceleration sensor 60 assists the high-speed image capture unit 20 in determining the start and end points of the carrier H's travel.

[0020] The system 1 for measuring the start and end points of a carrier movement path according to this embodiment may also be equipped with various sensors, such as a pressure sensor, a humidity sensor, a gyro sensor, a magnetic sensor, and / or a temperature sensor. Observation data from these sensors is also transmitted to the mobile device M and the cloud server SE via the network N. In addition, various engine data and tire pressure detection data detected by the carrier's on-board diagnostic system (OBS) can also be transmitted to the mobile device M and the cloud server SE via the system 1 for measuring the start and end points of a carrier movement path according to this embodiment and through the network N.

[0021] 5, 6 and 7 are diagrams showing a system for measuring the start and end points of a carrier movement path according to another embodiment of the present invention. The system 1' for measuring the start and end points of a carrier movement path according to this embodiment includes a first host 100, a second host 200 and a third host 300. The first host 100 is installed on a first carrier H1, and the first host 100 includes a first processor 110, a first electromagnetic wave transmitting and receiving unit 120 and a first display unit 130. The first electromagnetic wave transmitting and receiving unit 120 and the first display unit 130 are all electrically connected to the first processor 110. The first electromagnetic wave transmitting and receiving unit 120 can transmit and receive measurement electromagnetic waves.

[0022] The second host 200 is installed on the ground, and includes a second processor 210 and a second electromagnetic wave transceiver unit 220. The second electromagnetic wave transceiver unit 220 is electrically connected to the second processor 210 and can transmit and receive measurement electromagnetic waves.

[0023] The third host 300 is installed on the ground, and includes a third processor 310 and a high-speed image capture unit 320. The high-speed image capture unit 320 is electrically connected to the third processor 310.

[0024] In a situation where the measurement system 1' for measuring the start and end points of a carrier movement process according to this embodiment is used on a track where there is no clear start line or finish line (specific structure on the ground), the first host 100 installed on the first carrier H1 detects changes in the intensity of electromagnetic waves to the second host 200 installed on the ground and close to the start line, which is inversely proportional to the square of the distance to the electromagnetic wave source, and determines whether or not there is a change in the distance between the first carrier H1 and the second host 200, thereby determining the start or finish of the movement of the first carrier H1.

[0025] The first processor 110 calculates the change in intensity of the electromagnetic wave received by the first electromagnetic wave transmitting and receiving unit 120 from the second electromagnetic wave transmitting and receiving unit 220, or the second processor 210 calculates the change in intensity of the electromagnetic wave received by the second electromagnetic wave transmitting and receiving unit 220 from the first electromagnetic wave transmitting and receiving unit 120, to determine the start and end times of the travel path of the first carrier H1, and the start and end times and the travel time are all displayed on the first display unit 130. Data such as the start and end times and the travel time can also be transmitted using the wireless transmitting and receiving unit and sent to the mobile device M or the cloud server SE via the network N.

[0026] Also, the high-speed image capture unit 320 of the third host 300 can more accurately determine whether the first carrier H1 has started moving or reached the end point. When the strength of the electromagnetic wave received by the first electromagnetic wave transmitting / receiving unit 120 of the first host 100 from the second electromagnetic wave transmitting / receiving unit 220 reaches a predetermined value, the first processor 110 sends a control signal to the third host 300, and the third processor 310 of the third host 300 starts the high-speed image capture unit 320 and captures the same frame image of the standard line and the first carrier H1 as a judgment image (see FIG. 7). The standard line is a mark on the high-speed camera device of the high-speed image capture unit 320. The third processor 310 loads the image identification unit 330 and determines the start point, end point, and travel time of the carrier's movement journey based on the presence or absence of a change in the distance between the standard line and the first carrier H1 in the judgment image. In another embodiment, the high-speed image capture unit 320 of the third host 300 also operates continuously and does not need to be started by a control signal from the first host 100.

[0027] 8 and 9 are diagrams showing a system for measuring the start and end points of a carrier movement path according to yet another embodiment of the present invention. Since this embodiment has some configurations that are the same as those of the previous embodiment, the same parts are labeled with the same symbols and their explanations are omitted. The system 1" for measuring the start and end points of a carrier movement path according to this embodiment further includes a fourth host 400. The fourth host 400 is installed on the second carrier H2. The fourth host 400 includes a fourth processor 410, a fourth electromagnetic wave transceiver unit 420, a fourth display unit 430, and a fourth identification unit 440. The fourth electromagnetic wave transceiver unit 420, the fourth display unit 430, and the fourth identification unit 440 are all electrically connected to the fourth processor 410. The first host 100 of this embodiment further includes a first identification unit 140, which is electrically connected to the first processor 110. The first identification unit 140 and the fourth identification unit 440 each transmit an identification signal to the second host 200.

[0028] The fourth electromagnetic wave transmitting / receiving unit 420 transmits and receives the measurement electromagnetic wave. The fourth processor 410 calculates the change in intensity of the electromagnetic wave received by the fourth electromagnetic wave transmitting / receiving unit 420, or the second processor 210 calculates the change in intensity of the electromagnetic wave received by the second electromagnetic wave transmitting / receiving unit 220, to determine the start and end times of the journey of the second carrier H2, and the start time, end time and journey time are all displayed on the fourth display unit 430.

[0029] In this embodiment, when multiple carriers race, the host of each carrier determines the change in electromagnetic wave intensity and at the same time transmits an identification signal, so that the second host 200 can determine the location of each carrier's host and determine the starting time, ending time, and journey time of each carrier.

[0030] The measuring system for the start and end of the carrier movement path of the present invention is installed on the carrier, and uses a high-speed image capture unit to capture the same frame image of the standard line installed in the lens and the specific structure on the ground, and also uses image identification technology to determine the distance between the standard line and the specific structure, and determine whether the carrier has started moving or reached the goal. In addition, the start and stop of the high-speed image capture unit are controlled by the satellite signal from the satellite position unit and the strength of the electromagnetic wave from the electromagnetic wave transmitting and receiving unit. Therefore, since the measuring system for the start and end of the carrier movement path of the present invention is installed on the carrier, even if the starting point and the end point of the circuit are changed, it can perform the measurement, and there is no need to install it again. In addition, the image identification technology can accurately determine the time of the start and end of the carrier's path, and is not affected by weather or natural environment.
