In step 102, an image detection device is activated to acquire a non-radiation detection image of the object to be measured according to the position of the vehicle to be measured. The detection area of the image detection device is equivalent to the detection area of the radiation detection device, and a non-radiation detection image of the detected vehicle can be acquired. In some embodiments, the arrangement position of the image detection device can be equivalent to the position of the ray emitter of the radiation detection device, so that the detection area of the image detection device is equivalent to the detection area of the radiation detection device.
In step 103, the trigger timing in step 102 is adjusted according to the detection range of the first frame of non-radiation detection image. In some embodiments, the target of the adjustment may be such that the first frame of the non-radiographic image does not include the cab and includes a starting position behind the cab. Such as: if the image of the cab part is included, setting a trigger to increase the time delay; if the image of the container part is lost, the trigger time delay of the trigger is reduced. In the security inspection detection process, the trigger triggers the radiation detection device to change the working state at the same time as the trigger triggers the image detection device in the debugging process, or can synchronously trigger and change the working states of the image detection device and the radiation detection device.

In some embodiments, the commissioning may be targeted to reduce the vehicle-free area in the final frame of the non-radiographic image after the tail of the vehicle under test and include the tail of the vehicle under test in the non-radiographic image. If the vehicle-free area behind the tail of the detected vehicle is included, reducing the trigger time delay of the trigger; and if the tail part of the detected vehicle cannot be included, increasing the trigger time delay of the trigger.
According to the debugging method of the security inspection equipment, the radiation detection device can be turned off in time in the security inspection process through the matched debugging of the trigger and the image detection device, the detection of the detected vehicle after passing is avoided, and the safety is further improved.
In some embodiments, the time delay for the image detection device to start acquiring the non-radiation detection image after receiving the activation signal of the trigger may be further adjusted according to the preheating duration of the radiation emitter of the radiation detection device. Because the preheating time of the ray emitter is more obvious than that of the image detection device (such as a camera), the mode can prevent the actual ray emitting time of the synchronously activated ray emitter from lagging behind the image obtaining time of the image detection device, and the accuracy of the triggering time of the ray emitter in the actual use process is improved.

And acquiring a radiation detection image of the detected vehicle according to the detection result of the radiation detection device.
According to the security inspection method, the image detection device is adopted to replace the radiation detection device in the debugging process, the non-radiation detection image is adopted to replace the radiation detection image, and the trigger triggering time is adjusted according to the detection effect of the non-radiation detection image, so that the injury to workers in the debugging process is avoided, and the safety in the debugging process is improved.
In some embodiments, the trigger may synchronously trigger the changing of the operating states of the image detection device and the radiation detection device, and the step 303 is executed simultaneously with the step 302.
In step 303, during the security check, a non-radiation detection image of the detected vehicle is obtained according to the detection result of the image detection device.
By the method, two security inspection images of surface and radiation detection can be provided for workers, the surface and radiation detection images can be combined conveniently, the detection position can be determined, more abundant security inspection information can be provided, and reliability is improved.

In some embodiments, the image detection device 702 may also continuously detect, generate a whole vehicle image of the detected vehicle, and identify the cab avoidance position in the image according to the activation time of the trigger, so as to determine the accuracy of the cab avoidance according to the accuracy of the identified position.
In some embodiments, the image detection device may be configured to acquire the non-radiation detection image of the vehicle under test after delaying for a predetermined time period after receiving the activation signal of the trigger.

Schematic diagrams of further embodiments of the security check device of the present disclosure are shown in fig. 8.
The radiation detection device 701 may include a radiation emitter 11 and a radiation detector 12. The position detection means 3 cooperate with the trigger 4 to determine whether radiation detection or non-radiation detection is triggered.
In the debugging process:
when the cab of the vehicle passes through the detection area of the image detection device, the trigger 4 activates the image detection device to obtain a non-radiation detection image; after it is determined that the tail of the vehicle enters the detection region of the image detection device, the image detection device is prevented from acquiring the non-radiation detection image. The collected image data is collected and processed by the data collection system and then displayed by the display.
In some embodiments, non-radiation detection images during the test process can be obtained through continuous trial and error, and the trigger timing of the trigger can be adjusted according to the obtained images, such as:
adjusting the trigger time of the trigger according to the detection range of the first frame of non-radiation detection image after the trigger is triggered, and if the image of the cab part is included, setting the trigger to increase the time delay; if the image of the container part is lost, the trigger time delay of the trigger is reduced.
In some embodiments, the trigger prevention timing of the trigger may be adjusted according to the detection range of the last frame of the non-radiation detection image before the trigger-prevention-image detecting device acquires the non-radiation detection image of the object to be detected, and if a vehicle-free area behind the tail of the detected vehicle is included, the trigger delay of the trigger is reduced; and if the tail part of the detected vehicle cannot be included, increasing the trigger time delay of the trigger.
The safety inspection equipment can realize quick inspection and active imaging, complete testing and debugging are carried out, no extra radiation dose is generated, no radiation protection safety risk exists, and the avoidance accuracy of a cab and the safety degree of workers are improved.
In some embodiments, by adding a synchronous auxiliary information acquisition device including an adaptive image detection device 702 to the security inspection apparatus including the radiation detection device 701, the position detection device 703 and the trigger 704, the security inspection apparatus can be expanded and upgraded, so that the security inspection apparatus can be safely and quickly debugged, and the surface image of the detected vehicle can be acquired in the security inspection process, thereby improving the detection accuracy.
