Example Embodiment
[0068] Embodiment 1. A vehicle size measurement system based on photoelectric sensing and TOF technology (hereinafter referred to as a vehicle size measurement system), such as Figure 1 to 6 As shown, it includes a control system, a detection system and a frame 1. The frame 1 is enclosed to form a detection area, and the detection system performs detection after the vehicle stops in the detection area;
[0069] The control system is connected with the detection system signal, the control system controls the detection system to work, the detection system sends the detected data information to the control system, and the control system analyzes the data information to generate corresponding vehicle size information.
[0070] The control system draws a three-dimensional model of the corresponding vehicle based on the generated vehicle size information.
[0071] The vehicle size information includes vehicle width information and vehicle outline information.
[0072] A mirror-symmetric wa...
Example Embodiment
[0108] Embodiment 2. A vehicle size measurement method based on photoelectric sensing and TOF technology to measure the vehicle in the detection area, such as Figure 8 As shown, including the following steps:
[0109] S1. The control system controls the walking mechanism 2 to move along the length of the vehicle, and records the position information of the walking mechanism 2;
[0110] Note: The position information is the position pulse count, and its acquisition method is the existing technology, so the information is not notified in this manual.
[0111] In this embodiment, the traveling mechanism 2 is made to move 5 times from the rear of the vehicle toward the front of the vehicle.
[0112] S2. Each time the traveling mechanism 2 moves along the length of the vehicle (from the rear to the front of the vehicle), the detection system scans the vehicle body to obtain the vehicle size information at that position;
[0113] The vehicle size information includes vehicle width informatio...

Abstract
The invention provides a vehicle dimensional measurement system based on photoelectric induction and TOF technology. The vehicle dimensional measurement system comprises a control system, a light curtain detecting system and a frame, wherein the control system is in signal connection with the light curtain detecting system; the frame is provided with mirror-symmetrical walking mechanisms; each walking mechanism is provided with a distance detecting module; two distance detecting modules correspond to each other; each distance detecting module is in signal connection with the control system, and is configured to detect a distance from a corresponding position to the vehicle body, generate a distance signal and transmit the same to the control system; and the control system is configured todrive the waling mechanisms to synchronously move along the length direction of the vehicle, record the positional information of the walking mechanisms, determine the positions of the rear view mirrors of the vehicle according to the positional information and the distance signal, and generate vehicle width information. The vehicle dimensional measurement system can accurately measure the width dimensions of various parts of the vehicle body. Compared with an existing measurement system just capable of measuring the widest value of the vehicle body, the vehicle dimensional measurement systemis complete and comprehensive in measurement, and is suitable for various scenes that need to measure the actual dimension of the vehicle.
Description
technical field [0001] The invention relates to the field of measurement technology, in particular to a vehicle size measurement system and method based on photoelectric induction and TOF technology. Background technique [0002] TOF, Time of flight, time of flight ranging technology. [0003] There are many occasions where it is necessary to measure the size of the vehicle outline. For example, in order to save resources during automatic car washing, the vehicle size is often obtained through the car model, or the vehicle size is detected, and then washed according to the obtained vehicle size; another method , During the vehicle inspection, the size of the vehicle will also be tested to determine whether the vehicle has been modified and whether the modification is compliant. [0004] Existing patent documents that have been published to automatically measure the size of the vehicle outline: [0005] Automobile outline size measuring machine (CN101685005B) proposes that ...
