Description

Technical Field

[0001] The utility model relates to the technical field of optical observation equipment, and more particularly to an auxiliary sighting device and a telescope. Background Art

[0002] Telescope-based aiming is a crucial requirement for snipers. However, traditional telescopes often only support functions such as monocular cameras or infrared cameras. While they are quite capable in night vision scenarios, they lack depth information detection, making accurate target location impossible. Traditional depth cameras, on the other hand, are often limited to indoor scenarios. In outdoor scenes, the density of depth cameras drops sharply, making it impossible to construct a dense depth map with complete structure. Therefore, we aim to achieve accurate and dense depth estimation by jointly collecting both images and applying existing algorithms such as registration and depth completion, thereby improving the generalization of depth cameras in outdoor scenes.

[0003] However, existing depth cameras often use a binocular structure with two visible light cameras to estimate dense depth based on parallax. In outdoor scenes, binocular cameras will inevitably produce visual occlusion areas, resulting in the inability to accurately estimate the depth of these areas, reducing the performance of the depth camera. In recent years, algorithms based on visible light images and sparse ranging information from lidar have gradually matured.

[0004] Therefore, how to construct an auxiliary sighting device based on lidar and visible light camera is a problem that technicians in this field urgently need to solve. Utility Model Content

[0037] Example 1

[0038] Reference Figure 1-Figure 4 As shown, the utility model discloses an auxiliary sighting device, including: a housing 22, a laser radar 21, a visible light camera 24, a mainboard 23 and a USB output port 25;

[0039] The laser radar 21 is arranged on the top of the housing 22; the housing 22 is open at one end and hollow inside to form a cavity, and an opening is provided at the tail end of the cavity;

[0040] The cavity houses a visible light camera 24 and a main board 23 connected thereto; the optical path of the visible light camera 24 passes through the opening and is on the same vertical line as the optical path of the laser radar 21;

[0041] The laser radar 21 is connected to the main board 23 via a wire passing through the top surface of the housing 22;

[0042] The USB output port 25 is located at the opening at the rear of the cavity, and the USB output port 25 is internally connected to the mainboard 23 .

[0043] In this embodiment, the shell 22 is a square cavity with an open end, a card slot is provided in the middle of the top surface, and a card foot is provided at the bottom end of the laser radar shell, which is adapted to the card slot of the shell 22; the optical path of the laser radar is parallel to the top horizontal plane of the shell 22; the bottom of the shell 22 is provided with bolts, threaded holes, card slots or card feet adapted to external equipment. For example, if a card foot is provided at the bottom of the shell 22, the external equipment can be provided with a corresponding card slot.

[0044] Among them, the shell 22 and the outer shell of the laser radar are both made of engineering plastics, which have high rigidity, small creep, high mechanical strength, good heat resistance, and good electrical insulation, and can be used for a long time in harsh outdoor environments.

[0045] In this embodiment, the laser radar 21 adopts a micro laser radar with a high detection distance, such as the TFmini-i industrial laser radar ranging sensor. The laser radar 21 is small in size and has a compact structure after being assembled with the shell where the visible light camera 24 is located, and does not add additional weight burden.

[0046] The shell 22 is relatively large, and its cavity can accommodate a visible light camera 24, a mainboard 23, and a USB output port 25. The visible light camera and the mainboard 23 are arranged in sequence in the cavity of the shell 22, and the optical path of the visible light camera 24 is parallel to the top horizontal plane of the shell 22. The USB output port 25 is located at the opening at the tail end of the cavity, opening outward and protruding from the shell 22.

[0047] Reference Figure 5 As shown, the mainboard 23 includes a dual input interface, a processing module, an output interface, and a power supply interface; the power supply interface uses a button battery, and this embodiment uses a CR2032 lithium manganese battery, which is connected to the processing module and is used to provide power support for each module;

[0048] The laser radar 21 is connected to the main board through a wire passing through the top surface of the shell 22, connecting to one of the dual-channel input interfaces; the visible light camera 24 is directly connected to the main board 23 in the inner cavity of the shell 22, connecting to the other channel of the dual-channel input interface; the processing module is connected through the dual-channel input interface to transmit the sensor electrical signals of the laser radar and the electrical signals of the visible light camera to the processing module for processing. After being processed by the currently mature depth completion algorithm, the processed electrical signals are output through the output interface.

[0049] The output interface is directly connected to the USB output port 25 for outputting the processed electrical signal. The USB output port adopts a USB-A type connector structure and complies with the serial bus standard. It can not only assist in aiming the telescope, but also be connected to a computer for data collection and calibration.

[0050] A visible light camera is a device that uses the visible light band (400-1100 nanometers) for image capture and sensing. It converts light signals into electrical signals by sensing the reflection, triggering or emission of visible light. This type of camera uses an electronic sensor (such as CCD or CMOS) to record the intensity and color information of light and convert it into electrical signals.

[0051] In this embodiment, referring to Figure 1 As shown, the visible light camera 24 is a monocular visible light camera, including a visible light camera support frame 241, a visible light camera lens 242 and a visible light camera lens 243;

[0052] Among them, the visible light camera support frame 241 adopts a skeleton support structure to ensure the relative stability of the visible light camera lens 243 and play a protective role; the visible light camera support frame 241 is placed in the square channel of the shell 22.

[0053] The visible light camera lens 242 uses a high-definition camera module. This embodiment uses the Pi HQ Camera M12 module with a focal length of 25 mm, which is compatible with the Raspberry Pi HQ Camera M12. The visible light camera lens 242 is located inside the visible light camera support frame 241 and is firmly welded together using hot melt welding or ultrasonic welding.

[0054] The visible light camera lens 243 is a light-transmitting lens and is nested in the front end of the visible light camera support frame 241 through a mortise and tenon connection; a circular or rectangular tenon is set on the edge of the visible light camera lens 243, and a mortise matching the shape and size of the tenon is correspondingly set at the front end of the visible light camera support frame 241; the material of the visible light camera support frame 241 is engineering plastic. In order to avoid wear, an appropriate amount of grease can be applied to the mortise and tenon connection to reduce friction, and the mortise and tenon connection should be cleaned regularly to remove dust and other impurities.

[0055] This embodiment is based on a monocular visible light camera and a laser radar, and consists of two sets of parallel optical paths: one laser radar and one monocular visible light camera. The signals obtained by the two are simultaneously input into the mainboard 23. A depth completion algorithm based on the laser radar and visible light images is used. This algorithm is a mature algorithm already available on the market and can output a reliable dense depth image. The image can be output through the USB output port 25. The overall structure is compact, and auxiliary observation and aiming without obstruction problems can be achieved.

[0056] The auxiliary sighting device provided by this utility model facilitates highly generalizable dense depth estimation of outdoor scenes. It can be used to assist telescopes in observing scenes, obtaining scene depth and assisting in aiming. It also utilizes a motherboard that supports model deployment and image processing to densify input signals. Combined with existing mature algorithms, this device addresses the practical challenges of depth estimation in outdoor scenes. Its size is significantly smaller than dual-visible-light cameras, allowing for effective integration with existing handheld telescopes.

[0057] Example 2

[0058] Reference Figure 1-Figure 4 As shown, the embodiment of the present utility model further provides a telescope, comprising a monocular telescope body 1 and an auxiliary sighting device as described in the first embodiment;

[0059] The auxiliary sighting device is fixedly installed above the monocular telescope main body 1, and the monocular telescope main body 1 adopts the BURRIS2003444.5-14x42SF structure.

[0060] In this embodiment, the monocular telescope body 1 and the auxiliary sighting device are spliced ​​in an upper and lower aligned manner, the auxiliary sighting device is placed directly above the front end of the monocular telescope body 1, and the bottom of the housing of the auxiliary sighting device is adapted to the monocular telescope body 1 with bolts, threaded holes, slots or feet.

[0061] For example, the relative position between the two is ensured to remain unchanged by a snap-fit ​​connection, and a snap-fit ​​foot adapted to the auxiliary sighting device is provided on the lower end surface of the auxiliary sighting device; in this embodiment, the snap-fit ​​foot is installed on the lower end surface of the shell 22, and the snap-fit ​​foot can be L-shaped or in other shapes; one or more snap-fit ​​grooves corresponding to the snap-fit ​​foot at the lower end of the shell 22 are provided above the monocular telescope body 1, and the snap-fit ​​foot and the snap-fit ​​groove are adapted to be connected, and can be disassembled for calibration when calibration is required.

[0062] In this embodiment, the mainboard 23 of the auxiliary sighting device includes a dual-channel input interface, a processing module, an output interface and a power supply interface;

[0063] The dual-channel input interface receives the electrical signals of the visible light camera sensor and the radar point cloud sensor, and outputs the electrical signals synchronously to the processing module. The output interface can output through the USB output port 25, and an external display device can be connected to assist in viewing and aiming. The display can also be switched in the monocular telescope body 1 to effectively assist the user in viewing and aiming.

[0064] In this embodiment, the monocular telescope body 1 adopts the BURRIS2003444.5-14x42SF structure; with the assistance of the auxiliary sighting equipment, the observer can obtain the target's visual range and depth detection range when observing distant targets, thereby improving the comprehensiveness and accuracy of observation.

[0065] In this embodiment, based on a mature algorithm already available on the market, it helps to achieve the visible light camera obtaining a dense image and the lidar obtaining a sparse depth point. According to the local mapping relationship between absolute depth and relative depth and the estimated linear mapping parameters of the sparse depth points, the relative depth obtained by the monocular depth estimation model is converted into an absolute depth and output. The output absolute depth can help the user better perceive the surrounding environment and prevent the perspective effect of the monocular visible light image from interfering with the user's depth perception.

[0066] The telescope in this embodiment facilitates the observation and detection of distant targets, ensuring consistency between the visual range and the depth detection range; it helps achieve the dual functions of depth perception and visible light image acquisition, providing users with rich observation and aiming information, and improving the efficiency and accuracy of combat or observation; and the rational layout of the components facilitates user operation and maintenance, thereby enhancing the user experience and satisfaction of the equipment.
