Abstract:
An image reconstruction method adapted to use with a planting bed is provided. The planting bed is constituted by a work platform disposed on a work plane and for supporting a plurality of plants thereon. The image reconstruction method includes steps of: capturing a plurality of images of the work platform from different positions on a monitoring plane to obtain a plurality of image data, wherein the monitoring plane is opposite to the work plane, the monitoring and work planes are parallel to each other in a visible range and have a predetermined distance therebetween; and performing an image stitching algorithm to stitch the image data into a two-dimensional image of the planting bed. A monitoring system of a planting bed is also provided.
Abstract:
A data transmission method suitable for transmitting a first data table from a server to a mobile device is provided, wherein the first data table has a plurality of first data fields. The data transmission method includes following steps. A maximum used bit number of each of the first data fields is identified, wherein when the maximum used bit number of one of the first data fields is 0, the first data field is deleted so as to form a second data table. The second data table is then transmitted to the mobile device.
Abstract:
A database transforming method suitable for transforming a first database of a host into a second database of a mobile electronic device is provided, wherein the first database has a plurality of original fields. First, a plurality of main fields and a composite field are created in the second database. The main fields are respectively corresponding to at least one of the original fields. The main fields and the composite field are used for displaying data in the original fields. Data displayed in the composite field is separated by separators. Next, data in each field of the first database is written into the corresponding main field or the composite field of the second database. In addition, a compressible database structure and a database transforming system are also provided in the present invention.
Abstract:
A structure of a planting bed includes at least a work platform, a plurality of first and second supporting rods, a sliding track and an image capture apparatus. The first work platform is disposed on a work plane for supporting a plurality of plants. The first supporting rods each extend in a first direction. The second supporting rods are disposed on the work plane and around the work platform to support the work platform on the work plane, and each are connected to two adjacent first supporting rods. The sliding track is disposed on a monitoring plane and extends in a second direction. The sliding structure extends in a third direction and an end thereof is disposed on the sliding track. The image capture apparatus is installed to the sliding structure for capturing images at different positions on the work platform while the sliding structure is being driven to slide.
Abstract:
A positioning method for a sensor node is provided, and the method includes steps of: providing a first antenna having a first omnidirectional radiation pattern on a first plane; rotating the first antenna about an axis substantially parallel to the first plane; transmitting a wireless signal while the first antenna rotates about the axis for every a predetermined central angle; receiving the wireless signal at the sensor node; obtaining Received Signal Strength Indications (RSSIs) of the respective wireless signals; and determining a location of the sensor node according to the RSSIs.
Abstract:
An exemplary locomotion analysis method includes steps of: acquiring a depth map including an image of a measured object, filtering out a background image of the depth map according to a depth threshold, finding out the image of the measured object from the residual image of the depth map, calculating three-dimensional (3D) coordinates of the measured object according to the image of the measured object has been found out, recording the 3D coordinates to reconstruct a 3D moving track of the measured object and performing a locomotion analysis of the measured object according to the 3D moving track. Moreover, an exemplary locomotion analysis apparatus applied to the above method also is provided.
