Description

Technical Field

[0001] This utility model relates to the field of laser scanning equipment technology, and more specifically, to a handheld laser scanning device with infrared detection. Background Technology

[0002] With the development of computer technology, the accuracy of information acquisition and reconstruction of 3D scenes by handheld laser scanning is getting higher and higher. Using 3D measurement technology to carry out environmental data acquisition and modeling such as infrastructure mapping, urban modeling, rapid building mapping, and open-pit mine surveying has become one of the mainstream methods for constructing 3D spatial models.

[0003] Thermal imaging technology is a passive infrared imaging technique that uses infrared thermal radiation detectors to capture and measure the surface temperature of objects by receiving the intensity of infrared thermal radiation energy emitted by them. This generates thermal images, displaying different temperatures with different brightness or colors. It can generate thermal imaging videos and images. Later, by combining visible light images and point cloud models and using image registration techniques, a three-dimensional thermal imaging model of the object can be created. This model can be used to analyze the influence of environmental factors on the surface temperature of scanned objects and their relationship to surface defects. It can also be used for energy analysis of objects based on their three-dimensional thermal imaging models, demonstrating a wide range of applications.

[0004] Currently, traditional scanners mainly rely on the operator holding the device with one hand to collect data from the target object. The scanning lens, battery, data processing and storage module of a handheld laser scanner are installed inside the handheld scanner. The battery life is affected by the size, but if the size is too large, it can easily cause arm fatigue for the operator during long-term use, affecting the accuracy of data collection.

[0027] Example

[0028] Please see Figure 1 and Figure 2 As shown, this application provides a handheld laser scanning device with infrared detection, including a scanner 1, a controller 2, and an irregularly shaped paint target 3.

[0029] The bottom of the scanner 1 is provided with a groove 11, and the handle 13 is detachably connected to the groove 11. Handheld scanning is achieved through the handle 13, making the entire handheld scanner more compact and easy to carry.

[0030] The front of the scanner 1 has a ring of laser scanning lenses 4 arranged in a circular pattern, with a thermal imaging lens 6 and an optical imaging lens 5 installed in the center. During scanning, it can perform thermal imaging and image acquisition of objects. To protect the various lenses, the front of the scanner 1 is equipped with a rubber lens cover 7, which can be put on the side of the scanner 1 to protect the lenses after the scanner 1 is turned off.

[0031] The scanner 1 has a power and data transmission cable plug 13 on its side. The scanner 1 is connected to the controller terminal 2 via a power and data cable harness 20 and transmits data.

[0032] The back of the scanner 1 is equipped with a thermal imaging display screen 8 and a thermal imaging control button 9. The thermal imaging display screen 8 can display the thermal image intuitively, while the thermal imaging control button 9 can adjust and control the thermal imaging process and the laser scanning process, so that the two can work separately and independently, or can work simultaneously using an automatic control system, saving operation procedures and facilitating data supplementation and collection.

[0033] Reference Figure 3 As shown, the controller 2 includes a housing, inside which a mobile battery module, a data processing module, and a data storage module are installed. A flip-up scanning display screen 16 and scanning control buttons 17 are mounted on the front of the controller. The battery module, data processing module, data storage module, scanning display screen 16, and scanning control buttons 17 are all electrically connected and electrically connected to the scanner 1 via a transmission harness 20 to process and store the thermal images and images obtained by the scanner. The flip-up scanning display screen 16 allows the operator to conveniently view the screen and operate the device in real time during the scanning process.

[0034] The controller 2 has adjustable elastic straps 14 installed on both sides of its housing. The elastic straps 14 can be wrapped around and fixed to the waist of the user, and secured with Velcro 15 or buckles. This allows the controller 2 to be strapped to the waist, reducing the weight of the handheld scanner. It can also be worn on the body for independent operation, without being limited by the distance to the computer processing unit and power supply.

[0035] The housing of controller 2 is made of common plastic or aluminum alloy. Data transmission ports 19 are located on the side of controller 2 for connecting transmission cables 20. The storage module consists of a built-in solid-state drive and an SD memory card. By configuring the storage module, data can be directly stored in it first, reducing the risk of data loss. Data can then be imported to the host computer for further analysis and processing via wired connection or SD memory card. The battery module uses a common lithium polymer battery, which has the advantages of high capacity and small size.

[0036] Please see Figure 4 As shown, the irregularly shaped paint target 3 consists of two parts: a base 21 and replaceable irregularly shaped paint stickers 22. The base 21 is made of lightweight plastic with embedded magnetic patches. The irregularly shaped paint stickers 22 have magnets on their backs, allowing them to be magnetically attached to the base 21. Alternatively, adhesive backing can be applied to both the base 21 and the irregularly shaped paint stickers 22 for bonding. The irregularly shaped paint stickers 22 are made in different shapes according to specific letters or numbers and are coated with paints of different infrared thermal emissivity, allowing for interchangeable use when scanning objects of different materials.

[0037] When using it, the irregularly shaped paint target 3 needs to be evenly adhered to the surface of the object being scanned. When adhering, avoid the damaged or defective parts of the object's surface. Depending on the surface material of the object being scanned, replace it with a replaceable irregularly shaped paint sticker 22 with different infrared thermal radiation emissivity. The shape of the irregularly shaped paint sticker 22 is clearly distinguishable by referring to numbers or letters, etc., and is used to accurately locate different targets.

[0038] When starting the scan, wear the controller 2 on your body using the adjustable elastic belt 14, connect the controller to the scanner using the transmission harness 20, and insert the handle 10 with a buckle into the groove 11 at the bottom of the scanner as a handheld handle. After powering on, perform a comprehensive and detailed scan and thermal imaging of the object. During scanning and thermal imaging, the scanning distance needs to be controlled between 0.3 meters and 1.5 meters to ensure scanning accuracy and the temperature accuracy of the thermal image.

[0039] After scanning, the collected 3D point cloud data, RGB images, and thermal imaging data are transferred to professional image registration software on a computer using an SD card or data transfer port 19. Using the spatial feature points formed on the RGB images and thermal imaging images by the irregularly shaped paint target and the color brightness reference points representing different temperatures, the RGB images and thermal imaging images are automatically registered, and the registered images are 3D mapped onto the point cloud, thus forming a thermal imaging 3D model with temperature texture more quickly and conveniently.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
