Detailed Description
Embodiments of the positional data loading apparatus and method of the present invention will be described in detail below with reference to the accompanying drawings.
The image detection expands the idea of edge detection to identify the whole image, and generally achieves the purpose of judging whether the detected image belongs to a certain image in a known image database or deducing that the image is most similar to a certain known image after comprehensive judgment. Image detection is also sometimes used to retrieve a given sub-image from a known image.
In real-world operations, image detection can be applied to various fields, such as detection of various types of objects in an image and various specific actions based on the detection result.
Currently, when a video terminal plays a video picture, the roll captions are loaded in a video content dense area, for example, an object dense position, which inevitably results in confusion of original content and delays a user from watching details, while a monotonous area of the object plays and loads fewer roll captions, and a large area of the video picture is wasted.
In order to overcome the defects, the invention builds a positioning type data loading device and a positioning type data loading method, and can effectively solve the corresponding technical problem.

In addition, the precursor of the GPS is a meridian satellite positioning system (Transit) developed by the U.S. military, which was developed in 1958 and put into use formally in 1964. The system works with a star network of 5 to 6 satellites, bypasses the earth at most 13 times a day, cannot give altitude information, and is not satisfactory in terms of positioning accuracy. However, the meridian system enables research and development departments to obtain preliminary experience on satellite positioning, verifies the feasibility of positioning by the satellite system and lays a cushion for the development of the GPS. The satellite positioning shows great superiority in navigation and the meridian system has great defects in navigation of submarines and ships. The American sea, land, air and military and civil departments feel urgent need for a new satellite navigation system.
For this reason, the united states naval research laboratory proposed a global positioning network project named Tinmation with an altitude of 10000km composed of 12 to 18 satellites, and launched one test satellite each in 1967, 1969 and 1974, on which an atomic clock timing system was preliminarily tested, which is the basis of accurate positioning of GPS. The united states air force proposed 621-B plans to form 3 to 4 constellation groups from 4 to 5 satellites per constellation group, wherein all the satellites except 1 satellite using a synchronous orbit use an inclined orbit with a period of 24h, and the plan propagates satellite ranging signals based on pseudo random codes, which have a powerful function of detecting signals with a signal density lower than 1% of the ambient noise. The successful use of pseudorandom codes is an important basis on which GPS has been successful. The naval plan is mainly used for providing low-dynamic 2-dimensional positioning for ships, and the air force plan can provide high-dynamic service, but the system is too complex. Since the development of both systems at the same time incurs significant costs and both plans are designed to provide global positioning, in 1973 the united states department of defense united states 2 into one, led by the united satellite navigation and positioning planning office, which was at the lead of the department of defense, and the establishment of a handling agency at the air force space in los angeles. The organization members are numerous, including representatives of the united states army, navy army, department of transportation, the national defense mapping office, the north convention, and australia.
