Container truck body measuring method and container truck body measuring system

Abstract

The invention discloses a container truck body measuring method, which comprises the following steps: 1) when a container body of a container truck body enters an acquisition region of an image acquisition device, taking a plurality of partial pictures of the external portion of the container body through the image acquisition device based on a preset frequency, and meanwhile, obtaining a plurality of partial X-ray pictures of the inner portion of the container body through an X-ray imaging system based on the preset frequency; 2) obtaining vehicle speed in any time section; 3) combining the plurality of partial pictures to form an external whole picture of the container body; 4) carrying out combining to form an internal whole picture of the container body; and 5)outputting the external whole picture of the step 3) and the internal whole picture of the step 4) and carrying out comparison display. The invention is to provide the container truck body measuring method and the container truck body measuring system, which can effectively obtain the overall picture of the container and enables the container to be accurately matched with objects in the container, and can carry out accurate positioning on the objects in the container.

Description

technical field

[0001] The invention relates to the field of vehicle inspection, in particular to a container truck body measurement method and a container truck body measurement system. Background technique

[0002] Chinese patent ZL201210196400.5 discloses an X-ray container truck real-time perspective imaging system, which can effectively realize the X-ray imaging display of the container of the container truck. It has the effects of energy saving, environmental protection, safety, real-time, economy and practicality.

[0003] However, the problems that this system cannot overcome are: 1. Due to the limitation of the lane distance and environmental protection, it is impossible for the X-ray imaging system to display the overall image of the container when the vehicle is changing speed. The shape of the object is easily deformed when the terminal display device; 2. Due to the limitation of the distance of the lane, the optical imaging system cannot display the overall ima...

Examples

Embodiment 1

[0055] Such as figure 1 As shown, a method for measuring the body of a container truck, the method is implemented through an X-ray imaging system and an image acquisition device installed at a preset position on one side of the lane, including the following steps:

[0056] Step 1: When the cabinet body of the container truck enters the collection area of ​​the image acquisition device, take multiple partial photos of the outside of the cabinet body through the image acquisition device at a preset frequency, and at the same time obtain multiple cabinet photos at a preset frequency through the X-ray imaging system Partial radiographs of the interior of the body;

[0057] Step 2: According to the overlapping area of ​​any two adjacent partial photos, judge the vehicle speed in the time interval when the two adjacent partial photos are taken; and obtain the vehicle speed in any time interval;

[0058] Step 3: Synthesize the overall external image of the cabinet through multiple p...

Embodiment 2

[0065] Such as Figures 1 to 3 As shown, a method for measuring the body of a container truck, step 1: when the cabinet body of the container truck enters the collection area of ​​the image acquisition device, take a plurality of partial photos of the outside of the cabinet body by the image acquisition device at a frequency of 25 times / min At the same time, the X-ray imaging system is used to obtain multiple local X-ray photos inside the cabinet at a frequency of 25 times / min;

[0066] Step 2: According to the overlapping area of ​​any two adjacent partial photos, judge the vehicle speed in the time interval when the two adjacent partial photos are taken; and obtain the vehicle speed in any time interval;

[0067] Step 2 specifically includes: S21: Obtain multiple feature points of two partial photos taken at adjacent time points;

[0068] S22: Comparing multiple feature points of the two partial photos in S21 to obtain multiple pairs of identical feature points;
