The present invention provides a security-based identification and following method, including: acquiring and processing environmental perception data to generate image information; matching the face features with a pre-stored suspect image database to determine the following target; when it is fixed following, According to the image information, a control signal is generated; the control signal is sent to the motor controller on the pan / tilt, so that the motor controller controls the speed of the motor according to the control signal, and drives the acquisition device on the pan / tilt to rotate; when the acquisition device rotates , to follow according to the following path; when following randomly, predict the trajectory of the following target according to the image information and map data, and calculate the time difference between the vehicle and the following target; when the time difference is not greater than the preset time threshold, Follow the target according to the real-time environment perception data and the track of the target. As a result, the environmental perception data is utilized, and the security effect is achieved.
Description
technical field [0001] The invention relates to the field of security technology, in particular to a security-based identification and follow-up method. Background technique [0002] Face recognition is a biometric technology for identification based on human facial feature information. A series of related technologies that use a video camera or camera to collect images or video streams containing human faces, automatically detect and track human faces in the images, and then perform facial recognition on the detected faces, usually also called portrait recognition and facial recognition. [0003] In the prior art, for security purposes, cameras are often arranged, and face recognition is performed through the data collected by the cameras, so as to identify abnormal persons. However, this method often has defects such as huge cost and dead ends in monitoring. [0004] Unmanned driving equipment is an intelligent device that senses the road environment through the on-board...
