DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0018] As Figs. 1-2 shown, a planar scanning device for making floor pattern template is provided. A large platform support 1 is set as the core support framework of the entire device. High-quality steel is selected and precisely forged to make the large platform support 1, which has excellent rigidity and anti-deformation ability, and lays a solid foundation for the stable operation of subsequent components. On the upper surface of the large platform support 1, a scanning platform 3 is firmly spliced by using high-precision welding technology. The table surface of the scanning platform 3 is treated by super-fine grinding, and the flatness error is controlled within a very small range, which strictly ensures that the floor can be placed in an absolutely horizontal state, creating basic conditions for accurate scanning. Along the long sides of the scanning platform 3, high-strength bolts are used to tightly fix transverse electric guide rails 2. The selected guide rail model has very low running resistance and excellent positioning accuracy, which can ensure the stability during frequent start-stop and variable-speed movement. According to the short side direction of the scanning platform 3, a longitudinal electric guide rail 8 is accurately installed on the transverse electric guide rail 2. Through careful adjustment, the two are perfectly perpendicular and orthogonal, and together build a precise and flexible two-dimensional moving frame, so that the subsequent loaded equipment can cover the scanning platform area in all directions.

[0019] On the longitudinal electric guide rail 8, a specially designed camera support 7 is first installed. The camera support 7 is designed to consider stability and adjustability, and aluminum alloy material is used to reduce weight while ensuring strength. Linear light sources and industrial cameras are cleverly placed in the upper and lower parts of the camera support.

[0020] The color line array camera 10 in the industrial camera is installed above the camera support 7, and the shooting direction is adjusted repeatedly and accurately set to 45° with the horizontal direction, so that the color light reflected on the surface of the floor 4 enters the camera lens at the best angle and captures the most abundant color details. The first linear light source is composed of the red and blue linear light source 9 and the green linear light source 6, wherein the red and blue linear light source 9 is strictly calibrated during installation, so that the irradiation direction is accurately perpendicular to the scanning platform, and the green linear light source 6 is adjusted to 45° with the horizontal direction, and after installation, the professional optical debugging equipment is used to ensure that the light source focal point of the first linear light source on the scanning platform is perfectly overlapped with the imaging focal point of the color line array camera 10, so that the light reflection information is efficiently taken by the color line array camera without omission, and the high-quality acquisition of the color image is ensured.

[0021] The black and white line array camera 11 is located directly below the color line array camera 10, and the inclination angle with the scanning platform 3 is small, which is finely calibrated and set to 22.5° with the horizontal direction. This angle setting helps to focus on the subtle changes of the floor texture in black and white grayscale and enhances the black and white contrast effect. The second linear light source cooperating with the black and white line array camera 11 selects the blue linear light source 5, which is installed to ensure that the irradiation direction is 15° with the horizontal direction, and the light source focal point of the light source on the scanning platform 3 is accurately overlapped with the imaging focal point of the black and white line array camera, providing strong support for black and white image capture.

[0022] The control system of the upper computer mainly consists of an industrial control computer as the upper computer and multiple distributed microcontrollers. The industrial control computer is placed in the operation console near the equipment, connected with the distributed microcontrollers through high-speed Ethernet cable, and a stable and reliable communication link is established. The drive motor of each horizontal electric guide rail 2 and vertical electric guide rail 8 is connected with a microcontroller respectively, which receives the motion instructions sent by the upper computer and accurately controls the speed, steering and start-stop of the motor, so as to realize the precise movement of the guide rail. The color line array camera 10 and the black and white line array camera 11 are connected with the upper computer through the image acquisition card, which converts the analog image signals collected by the camera into digital signals, and controls the exposure time, frame rate and other parameters of the camera according to the instructions of the upper computer. The red and blue linear light source 9, the green linear light source 6 and the blue linear light source 5 in the linear light source are respectively connected with an independent light source controller, which communicates with the upper computer and adjusts the brightness, color ratio and switching state of the light source according to the instructions sent by the upper computer.

[0023] The actual operation process of the embodiment is as follows: first, the floor to be scanned is placed stably and centrally on the working area of the scanning platform, the operator starts the computer control system connected thereto, enters the color image acquisition stage, and the system accurately controls the transverse electric guide rail, the longitudinal electric guide rail, the color line array camera, the red and blue line light source and the green line light source to work cooperatively. After starting, the color line array camera and the line light source scan at a uniform speed along the transverse direction row by row, after each row of scanning is completed, the longitudinal electric guide rail is accurately moved according to the preset interval, the next row of transverse scanning is started, and the above process is repeated until the floor is completely covered on one side and the color image acquisition is completed.

[0024] For the black and white image acquisition mode, the transverse electric guide rail, the longitudinal electric guide rail, the black and white line array camera and the blue line light source are controlled respectively, and the above similar scanning process is repeated to capture the black and white image information of the same side of the floor.

[0025] In the specific scanning step, the floor can also be carefully turned by 180° in the horizontal direction, and then the color image acquisition program and the black and white image acquisition program are started again in sequence, and the previous scanning action is repeated. Finally, a series of optimization processes such as fusion, noise reduction and contrast enhancement are performed on the collected multiple groups of images, and high-quality image data containing all clear and complete texture details of the floor are output, which will be directly used for accurate production of the floor pattern template, and provide accurate and reliable pattern blueprint for the floor production link.

[0026] The above only describes the embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent structure or equivalent process transformation using the contents of the utility model specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection range of the utility model.
