Car door monitoring system and car door monitoring method

Even in a case where an external camera image-captures a door of a car, with high precision, it can be set to be determined whether or not a foreign substance inserted into the door is present. A monitoring apparatus acquires a camera image that results from a camera image-capturing the vicinity of a door of a car using an external camera, from a camera. A processor of the monitoring apparatus detects the door from the camera image, sets a determination area based on a position of the detected door, acquires an image of the determination area from the camera image, determines whether or not a foreign substance inserted into the door is present, based on the image of the determination area, and performs report outputting to a monitor and a reporting apparatus according to a result of the determination.

SYSTEMS AND METHODS FOR IMPROVED OPERATIONS OF SKI LIFTS
20230192151 · 2023-06-22 ·

Systems and methods for improved operations of ski lifts increase skier safety at on-boarding and off-boarding locations by providing an always-on, always-alert system that “watches” these locations, identifies developing problem situations, and initiates mitigation actions. One or more video cameras feed live video to a video processing module. The video processing module feeds resulting sequences of images to an artificial intelligence (Al) engine. The AI engine makes an inference regarding existence of a potential problem situation based on the sequence of images. This inference is fed to an inference processing module, which determines if the inference processing module should send an alert or interact with the lift motor controller to slow or stop the lift.
