[0002] Current automotive camera temperature control technologies primarily rely on passive heat dissipation / insulation structures, such as adding metal heat sinks, insulation cotton, or simple temperature-controlled fans. These only achieve basic temperature regulation through physical structures and lack precise algorithmic active control mechanisms. While some technologies introduce simple temperature threshold judgments, they can only be implemented by turning on the fan at high temperatures and the heating wire at low temperatures. They cannot perform dynamic and fine-tuning based on real-time camera temperature, ambient temperature, and image quality feedback, resulting in adjustment lag and failing to meet the image quality stability requirements of extreme high and low temperature environments in automotive scenarios. Summary of the Invention

[0013] Please see Figure 1 The present invention provides a method for adjusting camera temperature and parameters, the method comprising: Step S100: Determine the abnormal vehicle temperature state based on the vehicle camera temperature and ambient temperature, including: When the difference ΔT between the vehicle camera temperature and the ambient temperature is greater than or equal to the first temperature threshold T1 (T1 can be 5-10℃), the vehicle is determined to be in an abnormal high temperature state. When the difference ΔT between the vehicle camera temperature and the ambient temperature is less than the first temperature threshold T1 and greater than the second temperature threshold T2 (T1 can be -5 to 0℃), the vehicle is determined to be in a normal temperature state. When the difference ΔT between the vehicle camera temperature and the ambient temperature is less than or equal to the second temperature threshold T2, the vehicle is determined to be in a low temperature state.

[0014] Step S200: Obtain multiple scene features during vehicle operation, and obtain scene adaptation coefficients based on all the scene features; Specifically, in this embodiment of the invention, the scene features include: ambient temperature, vehicle operating status, ambient weather, and scene duration.

[0015] The method for obtaining the scene adaptation coefficient based on all the scene features is shown in the following formula: ; In the formula, For scene adaptation coefficients; Basic adaptation coefficients; For the first i Weight coefficients for each scene feature; For the first i The quantified score of each scene feature; n is the number of scene features.

[0016] Next, feature segmentation is performed on each scene feature, and values ​​are assigned to each segmentation result, as shown in the table below:

[0017] Take the following scenario as an example: T env <-30℃, idling, cloudy, for 10 minutes.

[0018] Extreme ambient temperature: Extreme cold (< -30℃) → S1=0.7, W1×S1=0.4×0.7=0.28; Vehicle operating status: Idle speed → S2=0.3, W2×S2=0.2×0.3=0.06; Environmental meteorological characteristics: Cloudy → S3=0.1, W3×S3=0.3×0.1=0.03; Duration characteristics: >5 min → S4 = 0.2, W4 × S4 = 0.1 × 0.2 = 0.02; Sum: 0.28 + 0.06 + 0.03 + 0.02 = 0.39; Then finally Value: K = 0.8 + 0.39 = 1.19, rounded up to get 1.2.

[0019] Step S300: Obtain the initial image quality parameters of the camera output image; Specifically, image quality parameters include: sharpness score Q (range 0-10, the higher the score, the sharper the image), frame rate parameter F (unit: fps), noise index N (range 0-1, the larger the value, the more noise), latency parameter L (unit: ms), and blur (used to measure lens frost, range 0-1, the larger the value, the more frost).

[0020] Step S400, obtaining the temperature adjustment power based on the abnormal vehicle temperature state and the scene adaptation coefficient, including: When a vehicle is determined to be in an abnormal high-temperature state, the method for obtaining the temperature regulation power based on the scenario adaptation coefficient is as follows: P hot = P 散 × (ΔT - T1) × K ; In the formula, P hot P represents heat dissipation power. 散 The reference power of the heat dissipation component; ΔT is the difference between the vehicle camera temperature and the ambient temperature; T1 is the first temperature threshold. For scene adaptation coefficients; When a vehicle is determined to be in an abnormal low-temperature state, the method for obtaining the temperature regulation power based on the scenario adaptation coefficient is as follows: P cold = P 加 × (T2 - ΔT) × K ; In the formula, P cold P is the heating power; 加 The reference power of the heating component; ΔT is the difference between the vehicle camera temperature and the ambient temperature; T2 is the second temperature threshold. This refers to the scene adaptation coefficient.

[0021] The camera temperature control component operates according to the temperature control power and adjusts the camera parameters according to the initial image quality parameters, including: Step S410: When it is determined that the vehicle is in an abnormal high-temperature state, the camera temperature adjustment component is controlled to adjust the heat dissipation power P according to the heat dissipation power P. hot run; Step S420: Under the abnormal high temperature condition, when the noise index N is detected to be greater than the noise threshold N0 or the sharpness score Q is less than the sharpness threshold Q0, the frame rate F is reduced to reduce hardware power consumption and heat accumulation. Step S430: Under the abnormal high temperature condition, when the delay parameter L is detected to be greater than the delay threshold L0, the image transmission bandwidth of the camera is increased to reduce the transmission delay and ensure the smoothness of the image. Step S440: When it is determined that the vehicle is in an abnormal low temperature state, the camera temperature adjustment component is controlled to adjust the temperature according to the heating power P. cold run; Step S450: Under the abnormal low temperature condition, when the frame rate parameter F is detected to be less than the frame rate threshold F0 or the delay parameter L is detected to be greater than the delay threshold L0, the response speed of the camera image sensor is reduced. Step S460: Under the abnormal low temperature condition, when the detected ambiguity M is greater than the ambiguity threshold M0, the heating power P is increased. coldThe heating power can be increased by 20%-50%; In step S470, when it is determined that the vehicle is in a normal temperature state, the camera temperature adjustment component is controlled to operate so that the camera temperature is kept within the preset temperature range, while maintaining the standard parameters of the image sensor to ensure the basic clarity and smoothness of the image quality.

[0022] Step S500: Obtain the current image quality parameters of the camera output image after adjusting the preset time; Specifically, after the preset time of 1-3 seconds has elapsed, the current image quality parameters of the camera output image are obtained, and then compared with the preset standard to see if they meet the standard.

[0023] Step S600: When it is detected that the current image quality parameters have reached the preset standard, the camera temperature adjustment component is controlled to continue operating according to the temperature adjustment power; Specifically, the preset standards are: the sharpness score is greater than or equal to the sharpness threshold, the noise index is less than or equal to the noise threshold, the frame rate parameter is greater than or equal to the frame rate threshold, and the latency parameter is less than or equal to the latency threshold.

[0024] Step S700: When it is detected that the current image quality parameters have not reached the preset standard, the temperature adjustment power is adjusted until the image quality parameters of the camera output image reach the preset standard.

[0025] Specifically, when the current image quality parameters are detected to be below the preset standard, the temperature control power is increased. Specifically, when the vehicle is in an abnormally high temperature state, the heat dissipation power is increased by 10%-30%; when the vehicle is in an abnormally low temperature state, the heating power is increased by 10%-30%.

[0028] S3. When it is determined that the vehicle is in an abnormal high temperature state, the heat dissipation power is obtained according to the scene adaptation coefficient, and the camera parameters are adjusted according to the initial image quality parameters under the abnormal high temperature state; at the same time, it is detected whether the current image quality parameters meet the preset standard. If they do not meet the standard, the heat dissipation power is adjusted until the image quality parameters of the camera output image meet the preset standard.

[0029] S4. When it is determined that the vehicle is in an abnormal low temperature state, the heating power is obtained according to the scene adaptation coefficient, and the camera parameters are adjusted according to the initial image quality parameters under the abnormal low temperature state; at the same time, it is detected whether the current image quality parameters meet the preset standard. If they do not meet the standard, the heating power is adjusted until the image quality parameters of the camera output image meet the preset standard.

[0030] S5. When it is determined that the vehicle is in a normal temperature state, control the camera temperature adjustment component to operate so that the camera temperature is kept within the preset temperature range.

[0031] According to a method for adjusting camera temperature and parameters according to the present invention, the following three specific embodiments are provided: Temperature difference thresholds: T1=8℃, T2=-3℃; Image quality parameter thresholds: Q0=7, N0=0.3, F0=25fps, L0=50ms, M0=0.4; The scene adaptation coefficient K can be preset: high temperature and sun exposure driving K=1.2, low temperature and severe cold idling K=1.3, rainy and low temperature driving K=1.1, foggy and high temperature driving K=1.0, and normal scene K=0.8.

[0032] Example 1: High temperature and sun exposure driving scenario, ambient temperature Tenv=60℃, vehicle speed v=80km / h, vehicle status S=1, S=1 is driving, S=0 is idling; The camera temperature Tcam was 68℃, and ΔT = 68-60 = 8℃, which was determined to be an abnormal high temperature state. The scene adaptation coefficient K was determined to be 1.2. The image quality parameters were N = 0.45, Q = 6.2, F = 55fps, and L = 55ms, where N > N0, Q < Q0, L > L0, and F > F0. Calculate heat dissipation power P hot =20×(8-8)×1.2=0W, and at the same time, the image quality was found to be substandard, so the heat dissipation power was adjusted to P. hot =20×0.5×1.2=12W, start the camera's semiconductor heat sink to run at full speed; slightly reduce the frame rate from 55fps to 50fps to reduce hardware power consumption and heat accumulation, and at the same time start the noise optimization algorithm to reduce image noise; to address the issue of latency L>L0, adjust the image transmission bandwidth parameter, increase the transmission bandwidth from 100Mbps to 120Mbps to reduce transmission latency. After 2 seconds of adjustment, the current image quality parameters monitored are: N=0.28, Q=7.3, F=50fps, L=48ms. All image quality parameters have reached the preset standards; the current heat dissipation power is maintained at 12W.

[0033] Example 2: Low temperature and severe cold idling scenario, ambient temperature Tenv=-30℃, vehicle speed v=0km / h, vehicle status S=0; Data collected: Tcam = -34℃, ΔT = -34 - (-30) = -4℃, ΔT ≤ T2 = -3℃, indicating an abnormal low temperature condition; scene adaptation coefficient K = 1.3; initial image quality parameters: Q = 5.8, F = 20fps, L = 65ms, M = 0.5, where Q < Q0, F < F0, L > L0, M > M0, indicating that the lens has a frosting phenomenon.

[0034] Calculate heating power P cold =15×(-3 - (-4))×1.3=15×1×1.3=19.5W; The embedded ceramic heating element is activated to focus on heating the lens area; At the same time, the image sensor response speed parameter is improved, shortening the response time from 10ms to 6ms, accelerating image acquisition and transmission, and reducing latency.

[0035] After 3 seconds of adjustment, the following data was collected: Tcam = -31℃, ΔT = -1℃, switching to normal temperature state; Q = 7.5, F = 28fps, L = 46ms, M = 0.25, all image quality parameters have reached the preset standard; then the camera temperature adjustment component is controlled to keep the camera temperature Tcam stable within the range of -30±2℃.

[0036] Example 3: Driving in low temperature in rainy weather, ambient temperature Tenv=-5℃, vehicle speed v=60km / h, vehicle status S=1, humidity Hum=85%.

[0037] Data acquisition: Tcam = -9℃, ΔT = -9 - (-5) = -4℃, which is determined to be an abnormal low temperature state; the scene adaptation coefficient K is determined to be 1.1; initial image quality parameters: Q = 6.5, F = 23fps, L = 52ms, where Q < Q0, F < F0, L > L0; Calculate heating power P cold =15×(-3 - (-4))×1.1=15×1×1.1=16.5W; The heating component is activated, and the image sensor response speed parameter is increased, adjusting the frame rate from 60fps to 30fps, balancing smoothness and power consumption.

[0038] After 1.5 seconds of adjustment, Tcam = -6℃, ΔT = -1℃, switching to normal temperature state; current image quality parameters: Q = 7.2, F = 30fps, L = 47ms, reaching the preset standard; then control the camera temperature adjustment component to keep the camera temperature Tcam stable within the range of -6±2℃.
