Embodiment 1

[0034] see Figure 1a , is a flow chart of an indoor fingerprint collection method provided in Embodiment 1 of the present invention. The method of this embodiment is suitable for fingerprint collection in a certain indoor place, and the method can be realized by an indoor fingerprint collection device configured in an indoor fingerprint collection device. The acquisition equipment generally needs to be equipped with a walking device, a rangefinder and a signal receiving equipment. The indoor fingerprint collection device can be implemented by software, configured in the processor of the collection device, and controls the actions of the walking device, the range finder and the signal receiving device.

[0035] As shown in Figure 1, the method includes:

[0036] 110. Control the walking device of the collection equipment to move in the area to be measured;

[0037] This operation specifically controls the movement of the walking device of the acquisition device in the area t...

example 1

[0050] see Figure 1b and Figure 1c . Place the collection device in the Figure 1b In the area to be measured shown, the collection device 11 moves within the area to be measured under the drive of the walking device, and the range finder measures the relative distance between the surrounding objects of the collection device 11 and the collection device 11 , the contour map of the area to be tested determined according to the relative distance can be as follows Figure 1c shown. Figure 1c The two-dimensional point cloud data is used to show the Figure 1b A contour map of the area to be tested is shown.

[0051] It can be understood that, in this example, the contour map of the region to be measured includes a boundary contour of the region to be measured.

example 2

[0053] see Figure 1d , place the acquisition device in another area to be tested, and the area to be tested contains objects such as "table" and "chair". Wherein the acquisition equipment moves in the area to be measured under the driving of the walking device, and the distance finder measures the relative distance between the surrounding objects of the acquisition equipment and the acquisition equipment, and the to-be-measured area determined according to the relative distance A contour map of a region can be obtained as Figure 1d shown. Wherein, the first section of the outline (shown as d1) and the second section of the outline (shown as d2) of the outline map correspond to the edge of the ground two-dimensional space occupied by the object "table" in the area to be measured.

[0054] It can be understood that, in this example, the contour map of the region to be measured includes the contour of the object itself contained in the region to be measured.

Abstract

The invention provides an indoor fingerprint collection method, device and apparatus. The method includes that a walking device of a collecting device is controlled to move in a to-be-measured area; a distometer of the collecting device is controlled to work, and the relative distance between an object around the collecting device and the collecting device is measured; an outline map of the to-be-measured area is determined according to the relative distance; longitude and latitude coordinates of measuring points in the to-be-measured area are determined according to the outline map and the longitude and latitude coordinates of preset basic points of the to-be-measured area; a signal receiving device of the collecting device is controlled to receive wireless signals of the collecting device at the measuring points; according to the wireless signals and the corresponding longitude and latitude coordinates of the measuring points, fingerprint information of the measuring points is obtained. By means of the indoor fingerprint collection method, device and apparatus, indoor fingerprint collection is automatically finished during movement of the collecting device, manual route pre-planning is not required, the collecting efficiency is increased, manpower costs are saved, positioning and wireless signal collecting are real-timely performed on the measuring points during movement, and therefore, the indoor fingerprint accuracy is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of information technology, and in particular, to an indoor fingerprint collection method, device and equipment. Background technique [0002] At present, with the widespread popularity of wireless networks and the rapid development of mobile smart terminals, location-based services have received more and more attention, and have been widely used in emergency rescue, medical care, social networking, navigation and monitoring and other fields. Show a huge market prospect. [0003] In indoor environments, especially in hotspot areas, such as supermarkets, exhibition halls, hospitals, clubhouses, theaters, libraries, and prisons, people's demand for indoor location information is becoming stronger and stronger, in order to realize navigation and positioning, and personnel and material monitoring And other comprehensive intelligent services. The realization of wireless positioning is based on indoor...
