Description

Laser aiming device and method based on mobile phone app and camera

Technical Field

The invention relates to the field of image positioning and laser, in particular to a laser aiming device and method based on mobile phone app and a camera.

Background

At present, the use of CCD image sensors is the main means for viewing invisible light spots, the principle of operation of charge coupled devices is charge as a signal, and unlike most other devices which use current or voltage as a signal, the basic function of CCDs is charge storage and charge transfer. It stores signal charges generated by optical or electrical excitation, and when a pulse of a specific timing is applied thereto, the stored signal charges can be directionally transferred within the CCD. The main problems in the operation of CCDs are the generation, storage, transmission, and detection of signal charges. However, these devices have the following problems:

1. the price of the ccd equipment is high and small companies cannot afford expensive equipment.

2. For a linear object or a rod-shaped object, such as an overhead power transmission line of a power grid, a red flag pole, a suspended rope and the like, since far infrared laser is irradiated in the air, the infrared laser is difficult to be irradiated on the power transmission line or the flag pole, and the laser spot cannot be observed by using the ccd, so that the laser cannot be positioned on a target object.

Disclosure of Invention

The invention mainly solves the problems that in the prior art, a CCD image sensor is adopted to position a laser aiming position, the price is high, and a thread or a rod cannot be positioned, and provides a laser aiming device and a laser aiming method based on a mobile phone app and a camera.

The technical problem of the invention is mainly solved by the following technical scheme: the utility model provides a laser sighting device based on cell-phone app and camera, includes camera, laser instrument, WIFI router and cell-phone end, the camera is installed on the laser instrument, and the camera links to each other with the WIFI router is wireless, and the WIFI router links to each other with the cell-phone end is wireless, installs the app that the position was aimed to the adjustment laser in the cell-phone end. The structure formed by the camera, the laser, the WIFI router and the mobile phone end is adopted to replace the existing CCD equipment, the structure is simple, the installation is convenient, the manufacturing cost is low, the CCD equipment is not required, and the bearing pressure of small companies is reduced. The invention has small volume and light weight, and is easy to be integrated into other systems. The invention utilizes the camera to watch the facula of the laser irradiated on the object.

As a preferable scheme, the camera adopts a high-resolution long-focus camera and a UVC-driven camera, the resolution is 700-900 ten thousand pixels, and the focus is 10-30 mm. This scheme has injectd camera resolution ratio and focus, can wash through the camera that satisfies the requirement and see the small-size debris within 200m, and the sighting position of maring will be more accurate like this, the precision is higher. The resolution ratio is lower than 700 ten thousand, the resolution ratio is too low, the aiming position cannot be found conveniently at the mobile phone end, the precision is influenced, the resolution ratio is higher than 900 ten thousand pixels, the price of the camera is improved, and the cost is increased. Similarly, the focal length is too short when being less than 10mm, so that a clear image cannot be acquired, calibration of the aiming position is influenced, the precision is reduced, the focal length is too long when being more than 30mm, the price of the camera is improved, and the cost is increased.

A laser aiming method based on mobile phone app and a camera comprises the following steps:

s1, setting a calibration plate, and irradiating laser of the laser on the calibration plate;

s2, acquiring image data of the laser in real time by the camera, sending the image data to the mobile phone end through the WIFI router, and calibrating the aiming position of the laser by the mobile phone end;

and S3, acquiring the calibration position as a laser aiming position, and aiming the calibration position at the irradiation object according to the mobile phone end video image to finish laser aiming. According to the invention, the camera is used for checking the laser position from the mobile phone terminal picture, and the mobile phone terminal picture position is calibrated to be used as the laser aiming position, so that a user can aim an object according to the calibrated aiming position, and the operation is simple and rapid.

As a preferable scheme, the process of targeting location calibration in step S2 includes:

s21, the mobile phone end carries out image analysis processing on the received video information;

s22, finding out the position of the laser irradiation on the calibration board in the video picture of the mobile phone end;

and S23, taking the found position as a calibration position, and setting a calibration symbol for the calibration position in the video picture of the mobile phone terminal.

Therefore, the invention has the advantages that: 1. the structure that adopts camera, laser instrument, WIFI router and cell-phone end to constitute replaces current CCD equipment, simple structure, simple to operate to the cost is low, need not to adopt CCD equipment, has reduced the little company and has born the pressure.

2. The resolution and the focal length of the camera are limited, and the camera meeting the requirements can clean and see small impurities within 200m, so that the calibrated aiming position is more accurate and the precision is higher. The resolution ratio is lower than 700 ten thousand, the resolution ratio is too low, the aiming position cannot be found conveniently at the mobile phone end, the precision is influenced, the resolution ratio is higher than 900 ten thousand pixels, the price of the camera is improved, and the cost is increased. Similarly, the focal length is too short when being less than 10mm, so that a clear image cannot be acquired, calibration of the aiming position is influenced, the precision is reduced, the focal length is too long when being more than 30mm, the price of the camera is improved, and the cost is increased.

3. The camera is used for checking the laser position from the mobile phone terminal picture, and the camera terminal picture position is calibrated to be used as the laser aiming position, so that the user can aim at the object according to the calibrated aiming position, and the operation is simple and rapid.
