Abstract: A method for target detection based on a visible camera, an infrared camera, and a LiDAR is provided. The method designates visible light images, infrared images, and LiDAR point clouds, which are synchronously acquired, as inputs, and generates an input pseudo-point cloud using visible light images and infrared images, to realize alignment of multimodal information in a three-dimensional space and fusion feature extraction. Then the method adopts a cascade strategy to output more accurate target detection results step by step. In the present disclosure, different characteristics of multi-sensors are complemented, which improves and extends traditional target detection algorithms, improves the accuracy and robustness of target detection, and realizes multi-category target detection in a road scene.

The input unit is provides the processing unit with a monitor infra-red image of the switchgear. The processing unit implements a machine learning classifier algorithm to analyse the monitor infra-red image and determine if there is one or more anomalous hot spots in the switchgear. The machine learning classifier algorithm has been trained based on a plurality of different training infra-red images. The plurality of training infra-red images include a plurality of modified infra-red images generated from a corresponding plurality of infra-red images, each of the modified infra-red images having been modified to remove an effect of obscuration in the image. The output unit outputs information relating to the one or more anomalous hot spots.

Abstract: A thermal image sensor to acquire a relative temperature and a temperature sensor to acquire an absolute temperature are provided in a space; a reference point is set at a position different from a temperature sensor installation position; and an absolute temperature of the reference point is estimated from a measurement value of the temperature sensor, a vertical component of a distance from the temperature sensor installation position to the reference point, a vertical component of a distance from the upper surface to the lower surface of the space, and a temperature coefficient of the space. A correction value is determined from the absolute temperature and relative temperature of the reference point, and an absolute temperature distribution is generated from the relative temperature distribution and the correction value. This allows a non-contact measurement of the absolute temperature of a measurement target with a simple configuration and without installation location restriction.
