Embodiment 1

[0042] Embodiment 1 of the present invention provides a device for measuring hidden feature positions under the surface of an object, which includes a detection module, which is used to detect multiple regions and generate multiple feature signals that vary based on differences from the hidden feature positions a controller coupled to the detection module, the controller configured to analyze a combined value of the plurality of signature signals to detect covert features; one or more indicators coupled to the controller, the indication The indicator is switchable between a first state and a second state; the controller is configured to switch the one or more indicators to the first state when the indicated position of the one or more indicators is above the concealed feature , otherwise switching to a second state such that the indicator in the first state identifies the location of the concealed feature.

[0043] as attached figure 1 As shown, in this embodiment, the detect...

Embodiment 2

[0059]The embodiment of the present invention discloses a device for measuring hidden feature positions under the surface of an object, which includes a detection module, which is used to detect multiple regions and generate multiple feature signals that are different from the hidden feature positions; a controller coupled to the detection module, the controller configured to analyze a combined value of the plurality of signature signals to detect covert features; a plurality of indicators coupled to the controller, the indicators capable of Switching between a first state and a second state; the controller is configured to switch one or more of the indicators to the first state when the one or more indicators are over the covert feature, and to switch to the second state otherwise two states, such that an indicator in said first state identifies the location of said concealed feature.

[0060] like Figure 5 As shown, in this embodiment, the detection module includes a plura...

Embodiment 3

[0079] This embodiment provides another device for measuring hidden features under the surface of an object for positioning, which includes a detection module, which is used to detect multiple areas and generate multiple feature signals that vary based on the position of the hidden feature a controller coupled to the detection module, the controller configured to analyze a combined value of the plurality of signature signals to detect covert features; a plurality of indicators coupled to the controller, the indicators capable of switch between the first state and the second state; further comprising a displacement sensor coupled to the controller, the displacement sensor is used to detect the displacement data of the positioning device; the controller is configured to, when a concealment is detected When the displacement generated after the starting point of the feature is equal to or greater than the set distance of the indicator, the indicator is switched to the first state, ...

Abstract

Disclosed in the present invention is a device for positioning a hidden feature. The device comprises: a detection module used to detect multiple regions and generate multiple feature signals varying on the basis of different positions of a hidden feature; a controller coupled to the detection module and configured to analyze a combination of the multiple feature signals to detect the hidden feature; and one or more indicators switchable between a first state and a second state and coupled to the controller. The controller is configured to switch the one or more indicators to the first state if marking positions of the one or more indicators are above a hidden feature, and otherwise switch the indicators to the second state, such that the indicators in the first state mark the position of the hidden feature. Also disclosed in the present invention is a positioning method for detecting a hidden feature. The present invention effectively adapts to a curved or uneven surface of a medium under test by means of combinations of the multiple feature signals, thus providing superior detection accuracy.

Description

technical field [0001] The invention relates to the detection field, in particular to a positioning device and method for hidden features in a medium. Background technique [0002] Currently, houses are built with sheltering features such as beams, columns, joists and other support objects placed under walls and floors, often with various wires and metal pieces Wait. After the floors and walls have been laid, it is often necessary to cut or drill into the supporting surface, or to make openings in the surface, due to the needs of various renovations, but at the same time must avoid damage to the underlying supports, wires and pipes, etc. In these cases, builders often want to know exactly where support items are behind walls or floors before work begins, to avoid cutting or drilling into them. In other cases, the builder may also often wish to anchor heavy objects to concealed support elements to ensure the firmness of the anchorage. Surface mount fasteners. However, onc...
