Method and system for alignment of illumination device
A method for providing assistance in aiming of one or more illumination devices in an area may include, by a processor, receiving photometric data for an area, and using the photometric data to determine an aiming vector for the illumination device. The area may include the illumination device. the method may further include receiving, from an orientation sensor module of the illumination device, orientation data for the illumination device, and using the orientation data and the aiming vector to determine if there is an error in the aiming of the illumination device. The response to determining that there is an error in the aiming of the illumination device, the method further includes causing a controller associated with a driving means of the illumination device for correcting the error in the aiming of the illumination device.
HEIGHT MEASUREMENT METHOD AND HEIGHT MEASUREMENT SYSTEM
The present invention provides a method for calculating a corrected substrate height map of a first substrate using a height level sensor. The method comprises: sampling the first substrate by means of the height level sensor with the first substrate moving with a first velocity, wherein the first velocity is a first at least partially non-constant velocity of the first substrate with respect to the height level sensor, to generate a first height level data, generating a first height map based on the first height level data, and calculating a corrected substrate height map by subtracting a correction map from the first height map, wherein the correction map is calculated from the difference between a first velocity height map and a second velocity height map.

Ground plane estimation in a computer vision system
Estimation of the ground plane of a three dimensional (3D) point cloud based modifications to the random sample consensus (RANSAC) algorithm is provided. The modifications may include applying roll and pitch constraints to the selection of random planes in the 3D point cloud, using a cost function based on the number of inliers in the random plane and the number of 3D points below the random plane in the 3D point cloud, and computing a distance threshold for the 3D point cloud that is used in determining whether or not a 3D point in the 3D point cloud is an inlier of a random plane.

SMART HEIGHT SAFETY SYSTEM
Apparatus and associated methods relate to a smart hook, a safety harness module (125), and associated electronic components that detect a safety state of a user by monitoring various parameters at the smart hook and safety harness module (125) and determining whether the user is using proper safety protocol at extreme heights and/or whether the user has experienced a height-related accident. In an illustrative example, the user may don a safety harness (115) that may include a module (125) that contains sensors that monitor an acceleration/velocity/position of the user and/or ambient air pressure around the user. The module (125) may receive wireless signals from at least one rebar hook (120a, 120b) having sensors that monitor the acceleration/velocity/position and gate position of the rebar hooks (120a, 120b). A controller included with the safety harness module (125) may use these sensors to advantageously determine the safety state of the user and generate alert/warning signals.
