Abstract: A thermal image-based temperature measurement calibration method applicable to a thermal image device is provided. The method includes a capturing stage, a processing stage and a calibration stage. During the capturing stage, the thermal image device captures a monitored environment to obtain a measured thermal image. During the processing stage, a processor processes on the measured thermal image to obtain a target information, wherein the target information corresponds to a target in the monitored environment, and the target information includes a target image block and a target measured temperature corresponding to the target image block. During the calibration stage, the processor obtains a distance compensation value according to a pixel number of the target image block, and the processor performs a calibration operation to the target measured temperature at least according to the distance compensation value to obtain a calibrated temperature value corresponding to the target.

Abstract: A particle sensing device, configured to detect a particulate concentration in a fluid, includes a detecting channel, a sensing space, a light source and a sensor. The detecting channel is configured for the fluid to flow therethrough. The sensing space is located on one side of the detecting channel and connected to the detecting channel, and the sensing space is surrounded by a surrounding wall. The light source and the sensing space are located on opposite sides of the detecting channel, and the light source is configured to emit light towards the detecting channel. The light is configured to hit at least one particle in the fluid. The sensor is disposed on an inner surface of the surrounding wall, and the sensor is configured to detect a scattered light energy generated when the light hits the particle. The sensor is a distance apart from the detecting channel.
