Embodiment Construction

[0040] The present invention can be further clearly understood through the specific examples of the present invention given below, but these examples do not limit the protection scope of the present invention.

[0041] like figure 1 As shown, the hardware part includes a CCD camera powered by 9VDC. The dual-core structure OMAP-L137 application processor with TI's C674x floating-point DSP core and ARM9 core is used as the main processor. Intensive real-time image recognition, matching retrieval processing and calculation, and ARM9 is responsible for non-real-time tasks, including the management and control of each module, task allocation, interface display, information query, data storage, etc., using FPGA as a coprocessor to integrate each module The drive is integrated into an FPGA chip, and the 3.7-inch LCD touch screen is used as the display module, which is installed in the casing together with the audio module and power supply. Using WinCE5.0 operating platform and VC6.0 e...

Abstract

The invention relates to a navigation method based on image identification technology and a navigation apparatus. The navigation method comprises the following steps: for an object, object image information is photographed; then, an object information database is created; during the use, a user photographs a particular object, obtains image information, retrieves in the database and obtains navigation information from the database, and then the navigation information is output to the user. The invention is free from easy interference during the use, has simple operation and low system cost, and is favorable for improving the performance of a navigation system and convenient for application scope expansion.

Description

【Technical field】 [0001] The present invention relates to a navigating method and equipment used, especially a navigating method based on PDA personal digital processing technology, adopting image recognition technology, capable of automatically retrieving relevant information, and realizing automatic playback of information and audio and video, and the method for realizing the method Handheld devices. 【Background technique】 [0002] When visiting exhibitions and exhibitions, people tend to be overwhelmed by the dazzling array of booths and exhibits, and tend to miss some exhibits they want to see. Often, the exhibits they are interested in reach out due to the large number of people or the quality of the speakers. Therefore, it is very necessary to study a kind of guide machine that can facilitate people to selectively visit exhibits, improve efficiency and save time. [0003] As a kind of electronic tour guide equipment, tour guide has been widely used in museums, exhibit...
