Abstract: 一种温度测量方法,包括如下步骤:S101、获取视场区域内至少一个待测目标的第一温度值(T0);S102、获取视场区域中对应待测目标的距离值;S103、根据步骤S102中获得的距离值,通过预先标定的距离与温度误差的函数关系计算温度误差,利用温度误差修正第一温度值(T0),得到第二温度值(T1),第二温度值(T1)即为待测目标的温度。通过利用深度相机(302)和红外探测器(301)采集同一视场区域,根据深度图像中待测目标的像素点确定待测目标在远红外图像中的位置;进一步根据深度图像中获取的距离值修正远红外图像中获取的温度值,获得待测目标的精确温度值,通过深度相机(302)与红外探测器(301)的协同作用提高测温的准确性。

Abstract: Techniques are disclosed for providing vehicular radiometric calibration systems and methods. In one example, a method includes capturing, by an array of infrared sensors mounted on a vehicle, a thermal image of a scene during navigation of the vehicle and/or while the vehicle is stationary. The thermal image comprises a plurality of pixel values. Each infrared sensor of the array is associated with a respective one of the plurality of pixel values. The method further includes determining temperature data associated with a portion of the scene, where the portion is associated with a subset of the plurality of pixel values. The method further includes generating a correction value based on the thermal image and the temperature data. Related systems, vehicles, and devices are also provided.

Abstract: Embodiments of the present disclosure provide a method for temperature detection. The method comprises obtaining a sensed temperature from a sensor, the sensor being in a mounted mode where the sensor is thermally radiated by a variable heat source and a fixed heat source; determining a temperature change rate of the sensor and at least one affecting factor that affects temperature sensing of the sensor; and determining a temperature of the variable heat source based on the sensed temperature, the temperature change rate, and the affecting factor. According to the method of the present disclosure, the temperature of the variable heat source such as an ambient temperature can be obtained or determined without a dedicated sensor and cables. With this method, the ambient temperature can be determined by a sensor for sensing a temperature of a heating element such as a battery, a control unit or the like. In this way, extra spaces and product designs for mounting a dedicated sensor for the ambient temperature are no longer needed, which reduces costs of the product. Furthermore, user experience can be improved without increasing costs.
