Abstract

The invention relates to the technical field of computer vision, and particularly discloses an event camera, a depth event point diagram acquisition method and device, equipment and a medium, the acquisition method comprises the following steps: acquiring event information and infrared point cloud information, the infrared point cloud information being acquired and generated based on a TOF module; obtaining first timestamp information of the event information and second timestamp information of the infrared point cloud information, wherein the first timestamp information and the second timestamp information are marked based on the collection frame rate of the TOF module; integrating the event information and the infrared point cloud information according to the first timestamp information and the second timestamp information to obtain the event point diagram with the depth information; the acquisition method has the advantages of being simple in operation logic and high in response speed.

Description

technical field [0001] The present application relates to the technical field of computer vision, in particular, to an event camera, a method, a device, a device and a medium for acquiring a depth event point map. Background technique [0002] Due to the limitation of frame rate and light intensity when sampling, traditional cameras have great difficulties in identifying high-speed moving objects or moving objects in dark light environments. Event cameras can solve these problems well, mainly through Set the illumination threshold and detect the light intensity changes at each point to passively trigger the output of event information, and then accelerate the output of event information through FPGA, so as to obtain the displacement information of approximately continuous high-speed moving objects in dark or strong light environments. [0003] However, the current event camera only has monocular output, and binocular construction is required when acquiring depth information....
