The invention discloses a method and apparatus of obtaining depth-of-field distance according to a depth image. The method of obtaining depth-of-field distance according to a depth image includes thesteps: obtaining and processing depth information to obtain the depth-of-field distance, and acquiring image information containing a target object; processing the image information to obtain depth image information; segmenting the depth image information of the target object in the depth image information; and according to the depth image information of the target object, determining the depth-of-field distance of the target object. The method of obtaining depth-of-field distance according to a depth image achieves the purpose of obtaining the depth-of-field distance of the tracking object soas to realize the technical effect of quickly locating the tracking object and accurately obtaining the depth-of-field distance of the tracking object in real time, and has the advantages of being simple in the method, being small in the calculation amount, effectively reducing the requirement for hardware and being easy to implement, promote and use.
Description
technical field [0001] The present application relates to the technical field of image recognition, and in particular, relates to a method and device for obtaining a depth-of-field distance from a depth image. Background technique [0002] With the rapid and in-depth development of the field of robotics, human-computer interaction technology has increasingly become one of the research hotspots. Among them, intelligent human body following is the main research part in the field of mobile robots. This technology can better serve users, improve and perfect the intelligence of human-computer interaction, and make effective responses to the instructions issued by users. The premise of following is that the robot can identify the object it needs to follow and the distance between it and the object to follow. At present, there are many following methods applied to robots, such as based on ultrasonic processing, infrared processing, and visual image processing, etc., all of which a...
