Description

Technical Field

[0001] This invention belongs to the field of scalp detection technology, and in particular relates to a hemispherical multi-view image acquisition device. Background Technology

[0002] Three-spectrum scalp detection uses physical imaging technology to observe the superficial, dermal, and subcutaneous tissues of the scalp using standard white light, cross-polarized light, and UV light. The control system selects and emits different spectra by controlling the illumination system. After amplification and filtering by the optical system, the light signals are received by the image acquisition chip and converted into digital photoelectric signals. These signals are then transmitted to the DSP processor for further processing and encoding, forming a standard USB signal required by the host computer. This USB signal is transmitted to the computer via a USB interface, received by the software system, and processed through calculation, decoding, and data processing to create a real-time video image.

[0003] Traditional scalp imaging tools require manual angle adjustment, making it difficult to obtain a full scalp image at once, which poses a risk of missed detections. When the patient's head moves or the lighting is uneven, the image may become blurry and of inconsistent quality, affecting the accuracy of hair loss area calculation. Doctors need to manually take multiple photos and synthesize a 3D model, which is time-consuming and relies heavily on operational experience. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a hemispherical multi-view image acquisition device, which can effectively solve the problems of the existing technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a hemispherical multi-view image acquisition device, including an acquisition housing and a connecting rod A disposed at the lower end of the acquisition housing, and further including:

[0007] A positioning sleeve is fitted onto the outer surface of the connecting rod A, and a fixed base is fixed to the lower end of the positioning sleeve. A positioning mechanism is provided on one side of the positioning sleeve for adjusting the height of the connecting rod A.

[0008] An extension plate is fixed to one side of the collection housing. A fixing mechanism is provided on the inner side of the extension plate to fix the patient's head and neck.

[0009] The acquisition component is located inside the acquisition housing.

[0010] Furthermore, a reinforcing rod is fixed to one side of the connecting rod A, and the reinforcing rod is inclined and has a triangular cross-section with the connecting rod A.

[0011] Furthermore, the positioning mechanism includes positioning screw holes and positioning bolts. Positioning screw holes are evenly provided inside the connecting rod A, and the connecting rod A is slidably engaged inside the positioning sleeve. The positioning bolts are threadedly connected to the inner side of the positioning sleeve and connected to the positioning screw holes.

[0012] Furthermore, the fixing mechanism includes a bracket, a connecting rod B, and a forehead soft rubber bracket. The bracket is fixed to the inner side of the extension plate, the connecting rod B is fixed to the inner side of the acquisition housing, and the forehead soft rubber bracket is fixedly connected to the upper end of the connecting rod B.

[0013] Furthermore, the forehead soft rubber support has a circular arc-shaped cross-section and is equipped with a silicone soft pad inside.

[0014] Furthermore, the acquisition components are arranged in groups and respectively located inside the acquisition housing at the front, upper left, left side, left rear, rear right, right side, front right, and top.

[0015] This utility model has the following beneficial effects:

[0016] This invention features a connecting rod A that can be slidably engaged with the inner side of a positioning sleeve. A positioning bolt passes through the positioning sleeve and connects to a positioning screw hole inside the connecting rod A, allowing adjustment of the connecting rod A's position. This enables adjustment of the acquisition housing's position according to the patient's needs. The patient's head is then placed in the center of the inner side of the acquisition housing, with the neck supported by a bracket and the forehead secured by the connecting rod B and a forehead soft rubber bracket. This ensures the patient's head is positioned at the central axis of the acquisition housing. Finally, multiple acquisition components capture images of the patient's scalp. Synchronous triggering of these components ensures image time consistency, and data is transmitted to a computer terminal via a wired network for observation and recording by medical personnel.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Please see Figure 1-4 As shown, this utility model is a hemispherical multi-view image acquisition device, including an acquisition housing 1 and a connecting rod A2 disposed at the lower end of the acquisition housing 1, and also includes:

[0026] A positioning sleeve 5 is fitted onto the outer surface of the connecting rod A2, and a fixing base 7 is fixed to the lower end of the positioning sleeve 5. A positioning mechanism is provided on one side of the positioning sleeve 5 for adjusting the height of the connecting rod A2. A reinforcing rod 3 is fixed to one side of the connecting rod A2, and the reinforcing rod 3 is inclined and its cross-section forms a triangle with that of the connecting rod A2. The reinforcing rod 3 strengthens the connecting rod A2 and prevents it from shaking during patient imaging, which would affect subsequent use. The positioning mechanism includes positioning screw holes 4 and positioning bolts 6. Positioning screw holes 4 are evenly distributed inside the connecting rod A2, and the connecting rod A2 is slidably engaged inside the positioning sleeve 5. The positioning bolt 6 is threaded into the inside of the positioning sleeve 5 and connected to the positioning screw hole 4. The connecting rod A2 can slide up and down along the inside of the positioning sleeve 5, which can be adjusted according to the height of the bed board and the position of the patient's head. The positioning bolt 6 can pass through the positioning sleeve 5 and connect to the positioning screw hole 4 inside the connecting rod A2, so that the position of the connecting rod A2 can be adjusted. Thus, the position of the collection shell 1 can be adjusted according to the patient's needs. At the same time, an electric push rod can be set inside the positioning sleeve 5, which can automatically adjust the position of the connecting rod A2, further improving the adaptability of the equipment.

[0027] An extension plate 8 is fixed to one side of the collection housing 1. A fixing mechanism is provided on the inner side of the extension plate 8 to fix the patient's head and neck. The fixing mechanism includes a bracket 9, a connecting rod B10, and a forehead soft rubber bracket 11. The bracket 9 is fixed to the inner side of the extension plate 8, the connecting rod B10 is fixed to the inner side of the collection housing 1, and the forehead soft rubber bracket 11 is fixedly connected to the upper end of the connecting rod B10. The patient's head can be placed in the center of the inner side of the collection housing 1, and the patient's neck is supported by the bracket 9. The forehead is fixed by the connecting rod B10 and the forehead soft rubber bracket 11, thus ensuring that the patient's head is positioned at the central axis of the collection housing 1. The forehead soft rubber bracket 11 has a circular arc cross-section and contains a silicone pad. The circular arc shape of the forehead soft rubber bracket 11 allows it to fit the patient's forehead, preventing discomfort and ensuring proper subsequent treatment.

[0028] The acquisition components 12 are located inside the acquisition housing 1. Nine sets of acquisition components 12 are respectively positioned at the front, upper left, left side, left rear, rear, right rear, right side, right front, and top of the acquisition housing 1. Each acquisition component 12 includes a visible light camera, a near-infrared camera, and a ring-shaped LED array. The visible light camera has a resolution of 2000... The camera has 10,000 pixels and is used for surface morphology imaging. The near-infrared camera can detect the activity of subcutaneous hair follicles. The ring-shaped LED array provides a uniform cold light source with fixed brightness and temperature. A laser projects a crosshair reference line to assist in positioning and detecting whether the head is in the camera's focus. Finally, the optical locator is installed at the top center of the acquisition housing 1, projecting a crosshair laser line downwards to mark the center position of the patient's head. When the laser locator detects a deviation in the head position (such as a difference in patient height), the height of the connecting rod A2 can be adjusted to align the center plane of the hemispherical housing with the highest point of the patient's scalp, ensuring that all cameras are focused on the scalp surface (focal length error ≤ 0.5mm). Multiple acquisition components 12 are triggered synchronously to ensure image time consistency. Data is transmitted to a computer terminal via a wired network for medical staff to observe and record.

[0029] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
