Embodiment 1
[0027] An embodiment of the present application provides a method for detecting an abnormality in a video display state, such as figure 1 As shown, the video shows that state anomaly detection methods include:
[0028] Step 101 , when a video monitoring start signal is received, obtain a first video image currently displayed by a video player, and store the first video image in a database as a reference video image.
[0029] Exemplarily, when the vehicle-mounted video monitoring subsystem is turned on, the camera installed in the compartment transmits the collected video images to the video player in the driver's cab for display, and the video monitoring start signal can be triggered by turning on the subway After the vehicle-mounted video monitoring subsystem is installed, the camera and the video player in the vehicle-mounted video monitoring subsystem start synchronously. When the video player is turned on, a video monitoring start signal is triggered. At this time, the vid...
Embodiment 2
[0048] The embodiment of the present application also provides a video display state abnormal detection device, such as figure 2 shown, including:
[0049] The first acquisition module 201 is used to acquire the first video image currently displayed by the video player when receiving the video monitoring start signal, and store the first video image in the database as a reference video image;
[0050] The second obtaining module 202 is used to obtain the second video image currently displayed by the video player as the target video image when the target interval is reached;
[0051] The determination module 203 is configured to determine whether the display state of the video player is abnormal according to the pixel comparison result of the target video image and the reference video image.
[0052] The video display state abnormality detection device provided in the embodiment of the present application, when receiving the video monitoring start signal, acquires the first v...
Embodiment 3
[0059] The embodiment of the present application also provides an electronic device, such as image 3 As shown, the electronic device includes: a processor 301, a memory 302, and a computer program stored in the memory 302 and operable on the processor 301. When the processor 301 executes the program, the video display state described in the above-mentioned embodiments is realized. The steps of the abnormal detection method, wherein the processor 301 and the memory 302 can be connected through a bus or in other ways, image 3 An example can be connected via a bus.
[0060]The processor 301 may be a central processing unit (Central Processing Unit, CPU). The processor 301 can also be other general-purpose processors, digital signal processors (Digital Signal Processor, DSP), application-specific integrated circuits (Application Specific Integrated Circuit, ASIC), field-programmable gate array (Field-Programmable Gate Array, FPGA) or Other chips such as programmable logic devi...
