     The first camera  303  can be at the front end of the probe head so as to achieve image acquisition of a front scene, and the second camera  304  can be arranged at the side end of the probe head so as to achieve 360-degree panoramic image acquisition of a side, and the two cameras can be displayed simultaneously. The first LED fill lamp  305  can serve as a fill lamp of the first camera  303 , and the second LED fill lamp  306  can serve as a fill lamp of the second camera  304 , so as to realize image collection operation under any light environment. 
     The second probe joint  302  is configured to connect to the first probe joint  203  in the detection apparatus  200  so as to transmit the filmed digital video signal. The second probe joint  302  may be a USB receptacle when the first probe joint  203  is a USB interface or may be a USB interface when the first probe joint  203  is a USB receptacle. 
     The probe  300  may specifically be made of a detachable circular flexible material so as to be able to bend at any angle to facilitate detecting. 
     In the present embodiment, the detection apparatus  200  can send a control instruction to the probe  300  via the first probe joint  203  and the second probe joint  302 . The controller  301  of the probe  300  responds to the control instruction, controls two cameras to collect the image information according to the control instruction, and returns the collected image information to the detection apparatus  200  via the two probe joints. The detection apparatus  200  sends the image information to a display control apparatus  100  via a wireless communication module so that the image information is displayed on the display control apparatus  100  for a technician to perform failure analysis and diagnosis of a vehicle according to the image information. 
     It should be noted that, in addition to the communication connection with the display control apparatus  100 , the detection apparatus  200  can also be connected to the upper computer of the vehicle fault diagnosis system through WIFI, or connected to a PC computer, or connected to a smart phone, etc., so as to realize the respective convenient mobile endoscope detection. 
     Different from the prior art, the endoscope system provided by the embodiments of the present application is capable of performing 360-degree panoramic detection in the front and on the side with a large imaging viewing angle when collecting image information, wherein the probe can be bent at any angle to freely adjust the detection position; when the image information is transmitted, the video signal can be transmitted over a long distance of more than 100 meters; when displaying the image information, one screen can simultaneously display the images of two cameras, and the two views can be freely switched; furthermore, high-pixel high-definition imaging can also be realized, and HDMI high-definition video projection can also be realized. The endoscope system according to the embodiments of the present application realizes the separate operation of image collection and image display, can conveniently and quickly store and read image information, and realizes a convenient, accurate, and highly efficient vehicle fault diagnosis operation while facilitating mobile operation thereof. 
     Finally, it should be noted that: the above embodiments are merely illustrative of the technical solutions of the present application, rather than limiting it; combinations of technical features in the above embodiments or in different embodiments are also possible under the idea of the present application, and the steps can be implemented in any order; there are many other variations of the different aspects of the present application as described above, which are not provided in detail for the sake of brevity; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skills in the art will appreciate that the technical solutions disclosed in the above-mentioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents; such modifications or replacements do not depart the essence of the corresponding technical solution from the scope of the technical solutions of embodiments of the present application.
