Abstract: A guardrail estimation method based on multi-sensor data fusion is provided. The guardrail estimation method comprises acquiring multi-sensor data and vehicle information, determining a traveling track of the vehicle based on the vehicle information, determining multiple guardrail sample points based on the multi-sensor data and the traveling track, and estimating guardrail information based on the multiple guardrail sample points. When the vehicle is controlled laterally, the guardrail information is used for correcting a lane line of poor quality; and when the lane line cannot be detected, the guardrail information is used for a lateral control downgrade processing, and the guardrail information also facilitates aided realization of fast and accurate expressway lane-level localization and realization of a higher-level aided driving function.

Abstract: An intelligent pesticide spraying robot self-adaptive to terrain of mountain land is provided. Walking mechanisms are respectively connected to both side ends of a chassis. A pesticide spraying mechanism includes rotary drive mechanisms respectively connected to both sides of the rear end of the chassis, telescopic spray boom mechanisms correspondingly connected to the rotary drive mechanisms, rotary nozzle mechanisms correspondingly connected to the telescopic spray boom mechanisms, a liquid pesticide storage box fixed to the top of the chassis, a first water pump fixed in the liquid pesticide storage box, and first water pipes in communication with the first water pump and the rotary nozzle mechanisms. A control chip of a control identification mechanism is communicatively connected to the walking mechanisms, the rotary drive mechanisms, the telescopic spray boom mechanisms, the rotary nozzle mechanisms, the first water pump, a front-end camera, side-end cameras and ultrasonic sensors respectively.

Abstract: The present invention relates to a device, system and method for automatic and unobtrusive caloric intake detection. The device comprises a respiration input for obtaining a respiration signal indicating the subject's respiration, and an analysis unit for analyzing the obtained respiration signal in the frequency domain by determining one or more respiration signal features from the obtained respiration signal in the frequency domain related to changes in oxidation and by detecting changes of the one or more determined respiration signal features to detect periods of caloric intake by the subject.
