Embodiment Construction
[0173] The present application will be further described in detail below with reference to the accompanying drawings.
[0174] This specific embodiment is only an explanation of the application, and it does not limit the application. Those skilled in the art can make modifications to the embodiment without creative contribution as needed after reading this specification, but as long as the rights of the application are All claims are protected by patent law.
[0175] The embodiment of the present application provides a video scene retrieval method, and the main purpose of the vision-based scene retrieval is to find the observation information (image or video sequence) of the same geographical location when the scene map is established according to the current observation information;
[0176] There are three main differences between vision-based scene retrieval and general image retrieval / video retrieval:
[0177] 1. In general image retrieval / video retrieval, the main benchm...

The invention relates to a video scene retrieval method and device, electronic equipment and a readable storage medium, and relates to the technical field of computers.The method comprises the steps that a current video sequence is obtained, the current video sequence comprises multiple frames of images, dense deep learning feature maps corresponding to all the frames of images are extracted from the multiple frames of images, and the dense deep learning feature maps are obtained; then time domain feature fusion is carried out on the basis of the dense deep learning feature maps corresponding to the frames of images to obtain respective fused features, spatial-temporal feature aggregation processing is carried out on the basis of the fused features corresponding to the frames of images to obtain a global feature descriptor corresponding to the current video sequence; retrieving from a global database based on the global feature descriptor corresponding to the current video sequence to obtain a first preset number of video sequences; according to the video scene retrieval method and device, the electronic equipment and the readable storage medium provided by the invention, the accuracy of retrieving the video sequence can be improved, and then the user experience can be improved.
Description
technical field [0001] The present application relates to the field of computer technologies, and in particular, to a video scene retrieval method, apparatus, electronic device, and readable storage medium. Background technique [0002] In recent years, with the emergence of application scenarios such as autonomous memory parking, intelligent logistics trolleys, intelligent robot meal delivery in restaurants, and autonomous drone cruises, it is very important to recognize the scenes that have been reached. In these application scenarios, a correct motion path is planned in advance and a scene map is established in advance when a task is performed for the first time (such as parking a car in its own parking space). Scene, perceive where it is on the scene map, and then follow the pre-planned path to follow the movement autonomously, or autonomously avoid obstacles and navigate according to the scene map. Therefore, the accuracy of scene re-identification is very important fo...
