An image detection method, performed by a server, the method comprising: extracting a first image and a second image at an interval of a preset time period from a video stream; performing pixel matching on the first image and the second image to obtain a total matching value of pixels between the first image and the second image; performing picture content detection on the second image in response to determining that the first image and the second image satisfy a preset matching condition based on the total matching value of the pixels; and determining that the video stream is abnormal in response to detecting that no picture content is comprised in the second image; characterized in that the performing picture content detection on the second image comprises: performing filtering processing on a frame region of the second image to obtain a to-be-detected image after the filtering processing; performing blur processing on the to-be-detected image to obtain a target to-be-detected image after the blur processing; calculating target blurriness of the target to-be-detected image; and determining that no picture content is comprised in the second image in response to detecting that the target blurriness is lower than a preset blurriness threshold; and/or, the extracting a first image and a second image at an interval of a preset time period from a video stream comprises: extracting the first image and the second image at the interval of the preset time period from the video stream at a current detection moment; before the performing picture content detection on the second image, the method further comprises: determining that a current matching result is a matching success in response to determining that the total matching value of the pixels between the first image and the second image corresponding to the current detection moment satisfies the preset matching condition based on the total matching value of the pixels; obtaining a stored historical matching result, wherein the historical matching result is a matching result obtained by performing pixel matching processing on the first image and the second image that are extracted at the interval of the preset time period at a historical detection moment; and determining a number of times of successful matching within a preset detection time period based on the historical matching result and the current matching result; and the performing picture content detection on the second image in response to determining that the first image and the second image satisfy a preset matching condition based on the total matching value of the pixels comprises: performing picture content detection on a current second image in a case that the number of times of successful matching within the preset detection time period is greater than or equal to a preset number of times. extracting a first image and a second image at an interval of a preset time period from a video stream;
