[0002] Depth cameras are often used in computer vision and robotics to obtain three-dimensional information of objects. The indicator light status of a depth camera is usually related to the function and status of the camera.

[0003] Generally speaking, the depth camera indicator light may light up in the following situations:

[0004] Normal working status: When the depth camera is operating normally, the indicator light may remain on, indicating that the camera is in a usable state.

[0005] Power On: When the Depth Camera is on, an indicator light may light up to indicate that the camera is receiving power and is ready to use.

[0006] Data transmission: When the depth camera is transmitting data, the indicator light may flash to indicate that data is being transmitted.

[0007] Failure or abnormality: When the depth camera fails or has an abnormality, the indicator light may light up or flash in different ways to alert the user and take appropriate measures.

[0008] The indicator light of the depth camera may have the following disadvantages:

[0009] Limited indicators: Depth cameras usually have indicator lights that only have a few states, such as on, off, or flashing, which may not provide enough information to understand the detailed status of the camera.

[0010] Susceptible to interference: Depth cameras are often used in complex environments, such as robots or self-driving vehicles. In these environments, other electronic devices may generate electromagnetic interference, causing the depth camera's indicator light to misjudge or flicker.

[0011] Visual blind spot: If the indicator light of the depth camera is located in front of or on the side of the camera, the status of the indicator light may not be observed from the outside due to the field of view.

[0012] Poor stability: When the depth camera works in a low-light environment, the indicator light may be dim or difficult to see, making it difficult for users to accurately judge the working status of the camera.

These all fall within the scope of protection of the utility model.

[0059] The embodiment of the utility model provides a frosted cover plate depth camera, which aims to solve the problems existing in the prior art.

[0060] The following specific embodiments are used to describe in detail the technical solution of the utility model and how the technical solution of the present application solves the above technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the utility model will be described below in conjunction with the accompanying drawings.

[0061] The utility model proposes a frosted cover depth camera, the cover is located in the front, and a frosted surface is provided on the inner side of the transparent area in front of the indicator light to achieve a uniform light effect, so that the uniform light effect is better, the field of view angle is larger, and the indication effect is better.

[0062] Figure 1 Schematic diagram of the structure of a frosted cover depth camera in the embodiment of the utility model. Figure 1 As shown, a frosted cover plate depth camera in an embodiment of the utility model includes:

[0063] Shell 1.

[0064] Specifically, the housing is the main external structure of a device, used to protect and support the internal components. The housing can be made of many materials, depending on the environment and needs of the device.

[0065] for example:

[0066] Metal materials: such as aluminum alloy, stainless steel, titanium alloy, etc. These metal materials have high strength and corrosion resistance and are suitable for various harsh environments.

[0067] Plastic materials: such as polycarbonate (PC), nylon (PA), etc. Plastic materials are light and low in cost, but their strength and corrosion resistance are relatively low.

[0068] Glass material: such as quartz glass, tempered glass, etc. Glass material has high transparency and is suitable for devices that need to display internal components.

[0069] When choosing a housing material, you need to consider factors such as the purpose of the device, environmental conditions, and cost. For example, metal may be a better choice for devices that need to withstand greater pressure or impact; glass may be more suitable for devices that need to display internal components; and plastic may be a more economical choice for cost-sensitive devices that do not require special corrosion resistance.

[0070] The infrared transmitter 2 is used to transmit infrared light.

[0071] Specifically, the infrared transmitter is used to emit infrared light. Infrared light is a type of light that is invisible to the naked eye and can be used for illumination or detection in bright or dark environments. The infrared transmitter can be a TOF camera or a structured light camera. The TOF (Time of Flight) camera calculates the distance from each sensor pixel to the target object by measuring the time difference or phase delay between the emission of the infrared (IR) signal and the reception of the infrared signal. The structured light camera measures the depth information of the target object through the parallax of infrared light reflection. Its advantage is that it can achieve higher accuracy and spatial resolution, and has lower requirements for ambient light.

[0072] The infrared receiver 3 is used to receive the infrared reflection signal of the target object.

[0073] Specifically, infrared receivers are used to receive infrared reflected signals from target objects. When infrared light hits the target object and reflects back, the infrared receiver can capture these reflected signals to determine the location and shape of the target object. There are mainly the following types of infrared receivers:

[0074] Photodiode: A photodiode is a semiconductor device that can convert light energy into electrical energy. In a depth camera, it can be used to receive infrared light and convert it into an electrical signal.

[0075] Avalanche Diode: Avalanche diode is a semiconductor device with high sensitivity and low noise characteristics. It can operate at high voltage, thus achieving longer-distance infrared reception in depth cameras.

[0076] Phototransistor: A phototransistor is a semiconductor device that can convert light energy into electrical energy. It has high sensitivity and low noise characteristics and is suitable for infrared reception in depth cameras.

[0077] The infrared receiver needs to match the infrared transmitter. For example, when the infrared transmitter is a structured light camera, the infrared receiver is a structured light receiver; when the infrared transmitter is a TOF camera, the infrared receiver is a TOF receiver.

[0078] Indicator light 4 is used for signal display.

[0079] Specifically, the number of indicator lights is at least two. The indicator light is used for signal display. It can display different information by flashing, changing color, etc., such as power status, working mode, data transmission status, etc. The number of indicator lights is at least two, so that there are multiple working states and richer information display. The indicator light is usually an LED indicator light, a digital tube, etc. The specific number and position of the indicator light can be selected according to the application scenario of the depth camera. The indicator light is usually located at the edge of the depth camera. The arrangement of the indicator lights is usually symmetrical.

[0080] The cover plate 5 is connected to the housing and is located in front of the infrared transmitter, the infrared receiver and the indicator light.

[0081] The cover plate 5 comprises a transparent area 6. The transparent area 6 is located in front of the indicator light, and a frosted surface is provided inside the transparent area in front of the indicator light to achieve a uniform light effect.

[0082] Specifically, the cover is connected to the shell and is located in front of the infrared transmitter, infrared receiver and indicator light. Its main function is to protect the internal components, and it can also play a certain aesthetic role. The transparent area is located in front of the indicator light and is used to display the status of the indicator light. Since the cover is transparent, the light of the indicator light can penetrate the cover and be directly displayed to the user. In the transparent area, a frosted surface is provided on the inner side. The main function of the frosted surface is to achieve a uniform light effect, making the light of the indicator light more uniform and beautiful. The cover is divided into two parts: a transparent area and other areas. The other areas can be the same as the transparent area or different. For example, the other areas can be made of opaque materials. However, no matter how the transparent area and the other areas change, it is necessary to ensure that infrared light can penetrate in front of the infrared transmitter and infrared receiver. In some embodiments, the other areas are made of materials that can penetrate infrared light but not visible light.

[0083] Frosting is a surface treatment method that is mainly achieved by making the originally smooth surface of an object become rough. Specifically, Figure 2 As shown, it mainly roughens the surface of the object, that is, obtains a frosted surface 9, so that when light is irradiated on the surface, diffuse reflection is formed instead of mirror reflection. For example, frosted glass is a typical object with a frosted surface. Its surface is rough, light is transparent but not see-through, and the light transmittance is about 50%-95%, which can make the indoor light soft and not glaring. A frosted surface is provided inside the transparent area to improve the uniform light effect. The frosted surface can reduce the reflection of light, so that the light is more evenly distributed in the entire transparent area, thereby improving the visual effect.

[0084] In some embodiments, Figure 3 As shown, the transparent area is composed of a plurality of independent areas having the same number as the indicator lights. Each indicator light corresponds to a transparent area. The transparent areas corresponding to different indicator lights are not connected to each other. When the transparent area can transmit visible light, while other areas cannot transmit visible light, the transparent area in this embodiment also has the function of limiting the field of view of the indicator light, so that only the target object that is currently undergoing identification, such as face recognition, can see the current indicator light information, thereby improving data security. This embodiment can also provide a more intuitive operating experience. Each independent indicator light area can represent a different state or function, which can be more easily understood and operated by the user.

[0085] In some embodiments, Figure 4As shown, the transparent area is a continuous area. The shape of the transparent area can be any shape such as a ring, a square, a circle, etc. When the depth camera is working normally, the entire indicator light area usually remains on. If the frosted cover depth camera is measuring the distance of an object, the relevant indicator light area may show a gradient effect to show the measurement progress. This design not only helps users understand and operate the depth camera more conveniently, but also provides a more continuous and smooth visual effect.

[0086] In some embodiments, Figure 3 and Figure 4 As shown, the transparent area is composed of at least two independent areas, but the number of transparent areas is less than the number of indicator lights. At least two indicator lights share one transparent area. The setting of the transparent area can be referred to the above part, which will not be repeated here.

[0087] In some embodiments, Figure 5 As shown, compared with the above-mentioned embodiment, a frosted cover depth camera in this embodiment further includes:

[0088] The rotator 8 is used to rotate the transparent area.

[0089] Specifically, the rotator is a mechanical device whose main function is to rotate the transparent part. In the implementation process, a common way is to provide elastic force to drive the transparent part to rotate by providing an elastic component and a cam part. In addition, there is also a transparent area of ​​a rotary transformer with an adjustable angle, which is characterized in that a plurality of lugs are provided on the outer wall of the transparent area. This design helps to adjust and determine the angle of rotation to meet different application requirements. At the same time, there is also a device called a one-way rotary buffer, which is mainly used to slowly screw on the toilet ring cover to prevent the impact and noise caused by rapid screwing. These different types of rotators differ in structure, function and application, so they need to be considered according to actual needs when selecting. The transparent area in this embodiment is a continuous whole, such as Figure 4 As shown in . During the rotation of the transparent area, the area in front of the indicator light is transparent, so that the signal of the indicator light can be transmitted in time. Since the transparent area is a part of the cover plate, in this embodiment, the transparent area can be rotated separately, and the cover plate can be rotated as a whole, thereby driving the rotation of the transparent area.

[0090] In some embodiments, within the transparent area, the transparent area that can be illuminated by the indicator light is provided with a frosted surface. This embodiment is suitable for a scene in which the transparent area can rotate. When the transparent area rotates, the annular area in front of the indicator light will be illuminated by the indicator light. Therefore, in this embodiment, all transparent areas illuminated by the indicator light are provided with a frosted surface, so that the signals emitted by the transparent area during the rotation process can pass through the frosted area, thereby obtaining a stable uniform light effect.

[0091] In some embodiments, the frosted surfaces corresponding to the indicator lights of different brightness are different. In practical applications, the brightness and color of the indicator lights may be different, and these differences can help users better understand and interpret the status of the device. Specifically, indicator lights of different brightness may correspond to different frosted surfaces. For example, an indicator light of higher brightness may be equipped with a coarser frosted surface, while an indicator light of lower brightness may be equipped with a finer frosted surface. This embodiment helps users quickly and accurately identify the current working status of the device. For example, a green high-brightness indicator light may indicate that the device is working normally, while a red low-brightness indicator light may mean that the device has encountered a problem or needs maintenance. It should be noted that the human eye has different perceptions of light of different wavelengths. For example, for LEDs with the same radiant energy, we will feel that red light is much brighter than green light. Therefore, when designing indicator lights, it is necessary to fully consider the perceptual characteristics of the human visual system to ensure that the design of the indicator light is both beautiful and practical.

[0092] In some embodiments, Figure 6 As shown, a groove 10 adapted to the indicator light is provided inside the transparent area to make the light emit more evenly. The groove design can be implemented in the following ways:

[0093] 1) By adjusting the shape and depth of the groove, the propagation path of light in the transparent area can be changed, so that the light is more evenly distributed in the entire transparent area.

[0094] 2) By using special materials or coatings, the light distribution effect can be further improved. For example, light-scattering materials or anti-reflective coatings can be used to reduce the reflection and scattering of light, thereby improving the utilization rate of light.

[0095] 3) By rationally arranging multiple grooves, multi-angle and all-round light emission can be achieved, thereby further improving the uniformity of the light.

[0096] 4) By adjusting the position and number of the grooves, the intensity and direction of the light can be flexibly controlled according to actual needs.

[0097] In some embodiments, Figure 7As shown, a protrusion 11 adapted to the indicator light is provided inside the transparent area to make the light more evenly emitted. Specifically, this design can be achieved in the following ways:

[0098] (1) By adjusting the shape and size of the protrusions, the propagation path of light in the transparent area can be changed, so that the light is more evenly distributed in the entire transparent area.

[0099] (2) The light distribution effect can be further improved by using special materials or coatings. For example, light-scattering materials or anti-reflective coatings can be used to reduce the reflection and scattering of light, thereby improving the utilization rate of light.

[0100] (3) By rationally arranging multiple protrusions, multi-angle and all-round light emission can be achieved, thereby further improving the uniformity of the light.

[0101] (4) By adjusting the position and number of protrusions, the intensity and direction of light can be flexibly controlled according to actual needs.

[0102] In some embodiments, the size of the groove or the protrusion is related to the FOV of the indicator light. Specifically, the size of the groove or protrusion needs to be designed according to the field of view (FOV) of the indicator light to ensure that the light can effectively cover the entire field of view. For example, if the FOV of the indicator light is large, it may be necessary to set a larger groove or protrusion to better scatter the light; conversely, if the FOV of the indicator light is small, it may only be necessary to set a smaller groove or protrusion. In addition, the shape and depth of the groove or protrusion will also affect the propagation path of the light in the transparent area, thereby affecting the uniformity of the light. By rationally arranging multiple grooves or protrusions, multi-angle and all-round light emission can be achieved, thereby further improving the uniformity of the light.

[0103] The embodiment of the utility model further provides an electronic device, which includes a frosted cover plate depth camera provided by any of the above embodiments, and the electronic device can be a mobile phone, a tablet computer, a payment device, a drone, a robot, a digital camera, etc. The utility model proposes a frosted cover plate depth camera, the cover plate is located in the front, and a frosted surface is provided on the inner side of the transparent area in front of the indicator light to achieve a uniform light effect, so that the uniform light effect is better, the field of view angle is larger, and the indication effect is better.
